uPVC stands for “unplasticized polyvinyl chloride,” which is a type of durable and weather-resistant plastic commonly used in windows and doors. PVC windows are commonly known as vinyl windows. PVC stands for “polyvinyl chloride,” which is a softer and less durable form of plastic used in pipes and other building materials. uPVC is generally considered to be more durable and weather-resistant than PVC, making it a better choice for windows and doors.

Typically, UPVC is cheaper than aluminum. However, the cost of windows can vary depending on the size, style, and features you choose, so it’s important to compare quotes from multiple suppliers before making a decision. Additionally, the cost of installation should also be taken into account when making a purchase.

Although uPVC windows are designed to resist fading, some fading may occur over time due to exposure to ultraviolet (UV) light from the sun. To reduce the risk of fading, it is recommended that you choose a window with a UV-resistant coating and keep your windows clean by regularly wiping them down with a damp cloth. Additionally, installing window coverings can also help to protect your windows from UV radiation over time.

One alternative to un-plasticised polyvinyl chloride windows that may offer better durability, aesthetics, and cost is aluminum windows. Aluminum is a strong and durable material that is resistant to weathering and corrosion, making it a long-lasting option for windows. Aluminum windows also have a sleek and modern appearance and can be customized with a variety of finishes and colors to suit your aesthetic preferences. However, In terms of cost, aluminum windows may be more expensive upfront compared to uPVC windows, but they often have a longer lifespan and require less maintenance, which can result in lower overall costs in the long run. Other options to consider include wood and fiberglass windows, which offer their own unique benefits in terms of durability, aesthetics, and cost.

UPVC, PVC, and vinyl are all types of plastic that can be used to make windows. All of these are strong, durable materials that can be used to make windows. The main difference between the three is the specific type of plastic used and the manufacturing process.

UPVC stands for “unplasticized polyvinyl chloride.” It is a type of plastic that is commonly used in the construction industry for things like window frames, doors, pipes, and siding. UPVC is known for its durability and low maintenance, as it does not rot or corrode like other materials.

PVC stands for “polyvinyl chloride.” It is a type of plastic that is often used in the construction of pipes, window frames, door frames and siding. PVC is also known as vinyl, which is known for its strength and low cost, but it is not as durable as UPVC and may require more maintenance.

What are uPVC windows?

UPVC windows are windows that are made from unplasticized polyvinyl chloride (UPVC), a type of plastic material. They are a popular choice for windows because they are strong, durable, low maintenance, and energy efficient. UPVC is also a good insulator, so this type of window can help keep your home warm in the winter and cool in the summer. They are also relatively inexpensive and easy to install.


UPVC (unplasticized polyvinyl chloride) has been used for windows and doors since 1935. It was initially developed as an alternative to traditional materials like wood and metal, which required more maintenance and had shorter lifespans. UPVC windows and doors became particularly popular in the 1970s and 1980s, as homeowners and builders were looking for low-maintenance, energy-efficient alternatives to traditional materials. The use of UPVC has continued to grow in popularity due to its features. Today, UPVC windows and doors are widely used in both residential and commercial buildings around the world.

What are some popular types of UPVC windows?

There are many different types of UPVC windows available on the market, each with its own unique features and benefits. These windows can be categorized according to their function, design, and energy efficiency. Some popular types of these windows include:

UPVC casement window

UPVC casement windows are windows that are hinged on one side and open outward like a door. They are a popular choice for both residential and commercial buildings because they provide good ventilation and are easy to open and close. Moreover, they are available in a range of styles, colors, and sizes to suit different tastes and needs.

To open a casement window, you simply turn the handle and push the window outward. The window will then pivot on its hinges, allowing you to open it fully. Some windows of this type have a crank handle that you turn to open and close the window, while others have a lever handle that you push or pull.

These windows are a good choice for hard-to-reach areas and offer excellent ventilation. They can also be used in commercial buildings, such as offices or retail spaces.

UPVC sliding window

UPVC sliding windows are similar to casement windows, except that they slide open instead of swinging outward. They are ideal for those looking to achieve a modern, efficient, and cost-effective solution to their window needs. Their slim profile and contemporary design allow them to blend seamlessly into any interior or exterior space. 

The working mechanism of these windows is very simple and easy. To open the window, you can simply pull the handle and slide the window to the side. Sliding windows are easy to open and close, making them a great choice for rooms where you often need to adjust the ventilation level. They are a good choice for areas with limited space, such as above a kitchen sink, small bedrooms, or bathrooms.

Single/double hung UPVC windows

Single/double hung UPVC windows are a type of window that consists of two sash frames, one above the other. This type of window has been used for centuries and is still a popular choice for residential buildings today. They are a classic and versatile choice for any room or space.

Single-hung windows The bottom sash is usually fixed in place, while the top one can be opened by sliding it up and down. They can also be used in rooms that require frequent ventilation, as the top sash can be opened to allow air to circulate.

Double-hung windows are similar to single-hung windows, with the addition of a second sash frame that can be opened. This allows for better ventilation and is often used in bedrooms or living rooms that require more airflow. Additionally, the second sash can be used for cleaning, as you can tilt it inwards for easy access.

Crank out UPVC window

Crank-out UPVC windows are a type of window that is opened and closed using a crank handle. This handle is attached to a mechanism inside the window frame that turns a gear, which in turn opens or closes the window. Crank-out windows are often used in homes and other buildings to provide ventilation or to allow light in, and they can be opened to various positions to control the flow of air or light. They are generally easier to open and close than windows that require manual lifting or sliding, and they can also be more energy efficient due to their ability to seal tightly when closed.

 They are often used in both new construction and retrofit projects. They are available in a range of sizes and styles to suit different needs and design preferences.

Tilt turn UPVC window

Tilt turn windows are a type of UPVC (unplasticized polyvinyl chloride) windows that have the ability to both tilt inwards at the top or open inwards from the side on a horizontal axis. They are popular in Europe and are gaining popularity in other parts of the world due to their versatility and energy efficiency. These windows are particularly useful in small spaces or in situations where full-size windows are not practical. They can be installed in both modern and traditional houses and can be customized to fit the style of the home.

Tilt-turn windows offer the benefits of both casement window and hopper window in one design. When tilted inwards, they allow for ventilation while providing a secure barrier against intrusions. When fully opened, they provide easy access to the outside and allow for maximum airflow.

These are some of the most popular types of best UPVC windows, each providing its own unique benefits and advantages. They are also available with some additional features like double glazing, mosquito net, sunscreens, etc. Besides these windows there are also other less popular forms of windows like bay windows, awning window and other. Moreover, door frames are also made with this uPVC material.

What are the benefits of UPVC Windows?

UPVC windows offer a number of advantages, making them a popular choice for both new constructions and retrofitting projects. UPVC offers the following benefits over other materials:

  • Durability – Durability is one of the greatest benefits of these windows. These windows are resistant to fading, cracking, and deterioration due to exposure to the elements or daily wear and tear. While on the other hand wood windows are more prone to fading, rotting, or warping with time. With proper care and maintenance, UPVC windows can last for decades.
  • Energy Efficiency – No one wants to pay extra for energy bills, and UPVC windows can help to reduce your energy costs. The uPVC frames offer superior insulation, while the double-glazed insulated glass, keeps the warmth in during the cold winter months and the heat out during the hot days of summer. That translates into less energy being wasted and lower energy bills for homeowners.
  • Cost-effective – How can we forget to mention the cost-effectiveness of these windows? UPVC windows are a cost-effective window choice. They’re generally less expensive than other types of windows, such as wood or aluminum. In addition, the long-term savings from energy efficiency and low maintenance make them a great option for homeowners. UPVC windows are a great choice for any budget-conscious homeowner.
  • Lower Maintenance – Another plus point of these windows is that they require very little maintenance. They just need to be wiped down with a damp cloth once in a while and they will remain looking like new for years.
  • Security – These windows are incredibly secure, providing a strong and durable barrier between the outside world and your home. They also provide added security with effective locking mechanisms that are designed to keep your home safe and secure.
  • Aesthetics – UPVC windows come in a wide variety of colors, styles, and sizes, so they can be customized to match any design style. They also add an attractive and stylish touch to any home or office space.

In addition to these common benefits, uPVC windows offer a range of benefits for wholesalers, retailers, and construction contractors. For example:

  • Easy Installation – These windows can be easily and quickly installed with minimal tools, saving time on installation.
  • Transportable – They are lightweight and easy to transport, making them a great option for large-scale projects.
  • Low purchasing cost – Their low purchasing cost means that contractors, wholesalers, and retailers can offer competitive pricing for their services and these products.

UPVC windows offer a great combination of practicality, durability, and aesthetics that is unmatched by any other type of window. With a wide range of benefits, they are an ideal choice for both commercial and residential projects. Whether you need to replace existing windows or add new ones, UPVC windows are an excellent choice for your project.

UPVC windows vs Aluminum windows, which is best?

The answer to this question depends on the needs and preferences of each individual. Both UPVC windows and aluminum windows offer great benefits in terms of durability, energy efficiency, and affordability. However, if you find yourself in a state of confusion and are unable to decide which one is best for your project, here are some points that will help you make an informed decision:


  1. Cost: UPVC windows tend to be more affordable than aluminum windows.
  2. Durability: Aluminium windows are more durable and long-lasting than UPVC windows, which may become brittle and discolored over time.
  3. Energy efficiency: UPVC windows are generally more energy efficient than aluminum windows, as they have a higher insulation value and are better at retaining heat.
  4. Maintenance: UPVC windows require very little maintenance and are easy to clean, while aluminum windows may require more regular cleaning and maintenance to keep them in good condition.
  5. Appearance: When it comes to appearance and aesthetics, no other window can beat aluminum windows. Aluminum windows have a sleek, modern appearance, while UPVC windows have a more traditional look.


Ultimately, the best choice for you will depend on your budget, the style of your home, and your specific needs and preferences. If you are seeking style, a modern look, and durability, then aluminum windows are the best choice for you. However, If you want an affordable yet durable window that is easy to maintain and has good insulation value, then UPVC windows are the right choice for you.

What types of colors are available with UPVC windows?

There are a huge number of colour options available in upvc windows and doors, including white, cream, beige, brown, and various shades of grey. Some manufacturers also offer wood grain finishes, which can give the windows a more natural look. In addition, many UPVC window manufacturers offer the option to customize the color of the windows by mixing and matching different colors for the frame and sashes. This can allow you to choose a color that matches the style and aesthetic of your home.

There are two main methods for achieving different colors on uPVC windows: coextruded uPVC profiles and film lamination.

Coextruded UPVC profiles

This involves adding a layer of color onto the profile during the manufacturing process. This can give you more vibrant and consistent colors, at an economical cost.

coextrued upvc profile

Colored Coextruded UPVC profiles are made by a process called coextrusion, which involves the simultaneous extrusion of two or more layers of different materials to create a single, composite profile. Although it is the most popular method to give color to UPVC windows’ profiles, it has many disadvantages. The following are some of the disadvantages: 

  • When the temperature fluctuates between hot and cold, the internal stress in the co-extruded profile may be released, causing the profile to deform and potentially leading to cracking in the weld
  • High investment for single and multi-color molds.
  • A log of negative feedback has been received from customers in extreme weather conditions.  
Film lamination  

Film lamination is a process in which a decorative colored film is applied to the surface of UPVC profiles using an adhesive. The process is typically carried out using a laminating machine, which applies heat, pressure, and adhesive to bond the film to the surface of the profile.

The film used for lamination is typically a high-quality, weather-resistant material that is available in a wide range of colors and patterns, including wood grain, stone, and solid colors. The film is first cut to size and then placed in the laminating machine, where it is positioned over the UPVC profile. The machine applies heat, pressure, and adhesive to bond the film to the surface of the profile.

profile color

Which coloring process is best, co-extrusion or lamination?

As mentioned earlier co-extrusion is economical but it has many cons like deforming of surface, peeling, and others. On the other hand, laminated UPVC profiles have more advantages over co-extruded profiles. The following are some of the advantages of lamination over co-extrusion:

  1. Non-bending of surface or deforming – The surface of lamination films will not bend or deform due to the lack of internal stress, as the film is applied to the surface of the UPVC profile rather than being co-extruded as an integral part of the profile.
  2. More design options –  Lamination films are available in a wide range of colors and patterns, including wood grain, stone, and solid colors, which can be easily and quickly changed during the lamination process. This allows for more design options compared to co-extrusion, which may be limited by the need to maintain the structural integrity of the multi-layered structure.
  3. Environmental friendly – Lamination is generally considered to be more environmentally friendly than co-extrusion, as it produces less waste and does not require the use of multiple layers of material.
  4. Small batch production – Lamination allows for flexible small batch production, as the film can be easily changed to produce different colors and patterns. This is not as easily achievable with co-extrusion, which is a more complex process that may not be suitable for small-batch production.
Do colored uPVC windows peel? 

UPVC windows made with laminated upvc profiles are highly durable and are not prone to peeling. However, windows made with co-extruded profiles may peel or fade over time, especially if they are exposed to harsh weather conditions or UV radiation. To ensure the longevity of your colored uPVC windows, it is important to choose windows made with laminated profiles and to follow the manufacturer’s recommendations for care and maintenance. Therefore, at Oridow we always use high-quality products. We are using Renolit films for achieving specific colors on upvc profiles

How to choose quality uPVC windows?

When shopping for uPVC windows, it’s important to choose windows that are of high quality to ensure they last for years to come. Here are some factors to consider:

  • Upvc profile – One factor to consider when choosing quality uPVC windows is the thickness and quality of the uPVC profile. The profile is the main structural component of the window and plays a significant role in the overall strength and durability of the window. A thicker profile with a higher wall thickness will generally provide better structural support and be more resistant to warping or deforming over time.


In addition, the number of chambers in the profile can also impact the overall performance of the window. A profile with multiple chambers can provide better insulation and energy efficiency, as well as increased structural strength and stability.

It is also important to consider the brand of the uPVC profile. German brands such as VEKA, REHAU, and DIMEX are known for their high-quality materials and advanced manufacturing processes, which can result in a more durable and reliable window. Chinese brands such as CONCH and Zhongcai may offer lower prices, but it is important to carefully evaluate the quality and performance of these products before making a purchase. At Oridow, we have both these German and Chinese brands.

  • Energy efficiency – The second most important factor that decides the quality of a window or a door is its energy efficiency. The energy efficiency values are measured in terms of U-value and g-value. They are measurements of thermal properties, or how well glass insulates. Make sure that you choose windows with the lowest U-value and highest g-value, and always choose windows manufactured and certified by a reputable organization.
  • Glazing – The importance of glazing cannot be overstated. Glazing helps to keep your home warm in winter and cool in summer, as well as reduce outside noise. Therefore, the glazing of the uPVC windows should also be of superior quality to ensure proper insulation and protection against noise, dust, and UV radiation. You should choose double-glazed uPVC windows or Tripple glazed for an extra layer of insulation. Moreover, you should also look for glazing that is certified to meet the standards of your local building codes.
  • Window type – As mentioned earlier, there are several different types of uPVC windows to choose from. Consider the size, shape, and style of your windows and choose a type that best meets your needs and preferences.
  • Hardware – The hardware, such as handles, locks, and hinges, should be of high quality to ensure smooth operation and longevity. There should be no gaps between the hardware and the window, which can allow air or water to get into your home.
  • Mosquito net – If you live in an area with a high prevalence of mosquitoes, you may want to consider choosing uPVC windows with a built-in mosquito net. This can help to keep your home or building protected from pests while still allowing for ventilation.
  • Multi-point locking mechanism –  Security is one of the features that a window or door must have in it to be considered of high quality. After all, you wouldn’t want to compromise your safety. A multi-point locking mechanism is an effective way to provide additional security for your windows and doors, as it engages more than one point along the uPVC frame to lock the window or door. Therefore, always look for windows and doors that have a multi-point locking system to ensure better safety and security.
  • Warranty – The product warranty is also an important factor to consider when evaluating uPVC windows. Make sure that the manufacturer offers a warranty for the product and its parts, including the frame, hardware, and glazing, so that you can be confident in the window’s quality.


By keeping all these factors in mind, you can ensure that you choose quality uPVC windows that will last for years to come.

How to choose the best uPVC window manufacturer?

When choosing a uPVC window manufacturer, it’s important to do your research and choose a company with a reputation for producing high-quality products. Here are some factors to consider:

  • Experience- Experience matters a lot in this industry, as it gives the manufacturer a better understanding of window designs and technologies. Choose a company that has been in business for many years and has a wealth of experience in the window industry with a proven track record of producing high-quality uPVC windows and doors.
  • Product Quality- The quality of the product is also a crucial factor when deciding on the manufacturer. After all, you don’t want to compromise on the quality of your windows and doors. One of the best methods to get insights on the quality of the products is to ask for a sample product from the manufacturer and inspect it closely for any signs of poor craft or inferior quality. You should also ask for a detailed list of product features and should check if it meets the standards.
  • Product range- As a wholesaler, you should have a complete range of windows and doors to meet the needs of your customers. Every customer has their own requirements. One can be interested in purchasing grey uPVC windows or double-glazed windows. The other might be interested in buying uPVC window with mosquito net or uPVC windows with vents. Therefore, look for a manufacturer that offers a range of uPVC window styles, colors, and sizes to choose from. This will allow you to cater to the needs of your customers.
  • Customization options- As a construction contractor, you might also have some specific requirements for your customers and business needs. For such cases, look for a manufacturer who offers customization options and can customize their products to meet the requirements. This will ensure that you can get the product of your choice without any kind of compromise.
  • Customer service- Choose a company that offers good customer service and is willing to answer any questions or queries that you may have in a timely manner.First, consider the responsiveness of the manufacturer to your inquiries. Second, look for customer reviews and ratings as this will provide a good indication of how the company performs when it comes to customer service. These two things will give you an indication of the quality of customer service you can expect.
  • Price- Last but not least, price is an important factor. However, remember that the cheapest option is not always the best choice. Thus, make sure you are getting value for money and not compromising on quality. Check the prices of different manufacturers and compare them to get an idea of the lower cost, average cost and high cost.

So, these are some of the important factors to consider when choosing a uPVC window manufacturer. If you keep all of them in mind, you will be able to find the most suitable window manufacturer for your needs and ensure you get a quality product that will last for years to come.
