Double Hung window

A double-hung window has movable top and lower sashes that can be raised and lowered to let in air. You can frequently generate better circulation in a room (or across an entire floor) than you could with other window styles because you can open both the top and bottom. Warm air vents out the top while cool air can enter through the bottom aperture. In order to provide wholesalers and contractors with clarity before their upcoming projects, this page will provide an exhaustive guide to double-hung windows.

uPVC Double Hung Window

Builders and contractors favor using uPVC double-hung windows for their projects frequently. They are constructed to last for a long time, use little energy, and need little in the way of upkeep (no matter your zip code). Here are some of the most highlighted characteristics of uPVC double-hung windows: 

 

1.    Dust and Termite Resistant: A peculiar feature of uPVC double-hung windows is that it reduces dust attraction to the windows and displays durability. Unlike many window types, uPVC is fully termite-free. They also do not serve as a breeding ground for other insects. Since they are made of synthetic materials, they are very simple to clean.

2.    Sound-Insulation: Besides offering durability, the double-hung uPVC windows also offer a certain level of sound insulation. If they are processed properly for soundproofing, they can offer excellent results. 

3.    Adaptability: Double-hung windows are appropriate for most house types, and they are available in various shapes, sizes, and stock colors. Different materials can be used to construct double-hung windows besides uPVC, which makes it pretty adaptable for every home. 

4.    Easy to clean and maintain: Modern double-hung windows include bands on both the top and lower sashes that may tilt out (the piece of the window that holds the glass). The ease with which UPVC double-hung windows may be cleaned and maintained contributes to its minimal maintenance requirements. 

5.    Energy-efficient: You can increase your property’s energy efficiency by installing uPVC window frames. uPVC is an excellent heat insulator with a low thermal conductivity, which means it does not allow heat to pass through its frames easily. 

6.    Varying degrees of permeability: Although double-hung windows may be outfitted with a four-sided weatherstripping option if not installed, the windows are not as secure as other types of windows, such as casement or fixed windows. It is to everyone’s advantage that modern double-hung windows are often constructed over older windows. 

7.    Sufficient ventilation: The bottom scarf or the top band may be moved vertically to open and close double-hung windows. This indicates that just fifty percent of the window may be open. However, this space is sufficient to keep homes well-ventilated in all seasons.

Ultimate Guide For Double Hung Windows

The History And Evolution Of Double-Hung Windows

Old objects have a certain allure, whether they be vintage movies, opulent homes, or design concepts that have been imported from earlier times. Particularly old-fashioned windows are still preferred by contractors and wholesalers owing to the increasing demand. Double hung windows stand out among the more conventional options and that is why they are preferred more.

Double Function

The majority of residential windows prior to the introduction of these devices were casement windows. The contractors and wholesalers had observed that the side-hung windows had a problem with their weighty hardware. Larger units couldn’t be produced by manufacturers due to the weight.

Robert Hooke developed a window design in the 17th century that enabled residents to raise and lower the sashes for simpler operation. By using a system of counterweights, he did away with the need for cumbersome equipment. This made it possible for producers to make these units in any quantity they desired.

Wholesalers can find unique selling points for these windows easily. The finished product fulfills two crucial needs: attractiveness and functionality. With their vertical orientation, narrow frame, and unique sizes, they are beautiful to gaze at. Additionally, when fresh air is required, they open widely. 

Benefits Of Double-Hung Windows

Like any other component of the house, a window gradually loses its usefulness. Wholesalers and contractors should realize when and why the windows should be replaced so that they can guide their customers accordingly.

Several issues are made worse by outdated windows, including:

  • allowing indoor air to penetrate from outside.
  • allowing the home’s heat or air conditioning to leave.
  • compromising the home’s security with shoddy fittings, damaged locks, or rotten frames.
  • letting moisture into the home, increasing the danger of water damage, mold, and mildew.

The cost of replacing a window is not as exorbitant as the buyers would only look at the long-term cost savings energy bill and piece of mind from single and double hung windows. 

Single-hung windows are a prevalent feature in older houses. It has two sashes, but the lower one slides up and down vertically while the top one is fixed (cannot move).

Double-hung windows have two sashes and resemble single-hung windows in appearance, but both sashes can be opened and closed. It can help keep the house better ventilated.

Double Hung Windows Provide Greater Long-Term Benefits To Your Customers

Although it is not as expensive as other house improvements, replacing old windows is still an investment. Depending on the style and quality, replacing a window can cost anywhere between $9,000 and $20,000.

Since home improvements are unquestionably an investment, consumers put a lot of time in doing research about the best manufacturer and latest styles within their price range.

If your customer already had a specific style of window installed previously, it does not mean that you need to offer them the same type of window. Replacement can be done using the latest styles. 

The windows’ price may change based on:

  • The state of the window casings right now
  • How many windows are required to be changed
  • Additional window elements (energy efficiency, double glazed, etc)
  • The window’s design (single hung vs. double hung)

If your customers are cost-conscious then they might have a difficult time choosing between a single hung window and a double hung window. Typically, single-hung windows cost between 10 and 20 percent less than double-hung ones. Although double hung windows cost more up front, they are ultimately a better option for replacing house windows.

Single hung windows are less expensive than double hung windows, which makes them seem like the “common man’s” solution. However, this is one of the few advantages single hung windows have over double hung windows.

There are many egregious disadvantages to single hung windows. For instance, they are more challenging to clean, offer fewer ventilation choices, are more challenging to access from the lower level, and need a little more upkeep.

Easy Installation, Simpler Cleaning

Because they are affordable and simple to install, the single operating sash form is a standard in the majority of new homes, apartments, and workplaces. The window’s more constrained range of motion makes it more challenging to install correctly.

Compared to other types of windows, installing a double hung window is pretty easy. However, when the installation is supposed to be done on second or third storey, you’ll need a ladder or extension pole to reach the top part of a single hung window since you can’t do it from the outside.

More Ventilation of Double Hung Windows Attracts Customers

Double hung windows are much more suitable for spaces where moisture tends to accumulate, such as restrooms. To fight humidity as well as the development of mildew and mold, the double operable sashes can offer more ventilation. Additionally, it will help with odor management more.

This is one of the prime reasons why customers demand double hung windows from wholesalers and contractors frequently. 

Double hung windows are unquestionably the better option for those who really appreciate having fresh air enter their interiors. They also aid in the removal of smells from spaces like restrooms and kitchens. 

Owing to this feature, wholesalers can expect increased demand over long term.

Luring Customers With Energy Saving Windows 

Double hung windows cost more up front, but the long-term benefits offer greater incentives. And that is what the wholesalers should be aware of. 

Insulated double hung windows will reduce the customers energy costs more and allow for more ventilation. In order to encourage residents to upgrade their windows and make them more energy-efficient, utility companies are now providing more rebates. 

Consumers now believe that it would help with the prices of new windows enough to possibly cover the cost difference between single hung and double hung designs.

Budget is frequently the deciding factor when deciding between single and double hung windows. Your customers would not mind paying a little bit more for double hung windows owing to the increased benefits.

Double Hung Window Vs. Single Hung

A single-hung window, also called a single-sash window, has a top, fixed sash, and a lower, operable sash. As a result, only the lower portion of the window moves up and down, while the top portion does not. Single-hung windows have a lower sash that allows for ventilation.

Single and double-hung windows have very similar appearances, and most businesses offer them in the same designs with the same glass packages and color choices. What, then, distinguishes them? 

Due to its reduced price and double-hung window-like appearance, the single-hung window is the most popular option for new homes. In contrast, the double-hung window is the most popular option for residential replacement windows. 

The single hung window has a fixed top sash and an operable lower sash, which is the primary distinction between a single-hung and double-hung window. That means the single-hung window offers less ventilation and is more difficult to clean on higher levels when compared to the double-hung window.

The appearance of single-hung and double-hung windows can be very similar, and they are frequently found in the same areas throughout a home, such as living rooms, family rooms, kitchens, and dining rooms.

Because the upper sash of double-hung windows can slide down and tilt inward, enabling you to easily clean both sides of the window from inside your house, they are a common window choice for second and third-story rooms, such as bedrooms. 

Double-hung windows are common in restrooms and kitchens because they effectively improve air circulation in a space prone to moisture build-up.

Here are a few interesting differences:

Appearance

The manner in which they each function is the primary distinction between the two. Because the upper sash of single-hung windows is not removable, the only way to open the window is to raise the bottom sash. Because both sashes of a double-hung window are movable, that type of window can have both sashes open at the same time.

When viewed from the exterior, single-hung and double-hung windows appear to be the same type of window. Some property owners decide to put single-hung windows on the ground level of their homes and double-hung windows on the upper stories of their dwellings. 

Both choices are available in a diverse range of frame materials, including aluminum, vinyl, fiberglass, and wood. There are also a number of different style alternatives available. The function of single and double-hung windows is what differentiates them from one another; their appearance is not particularly different.

Ventilation

The amount of ventilation provided by single-hung and double-hung windows is distinct from one another. In contrast to their single-hung counterparts, double-hung windows have two sashes that can be opened simultaneously, which results in increased ventilation. 

When both sashes are opened, they allow fresh, cool air to enter through the bottom sash while simultaneously allowing warm air to escape through the upper sash. 

Choose double-hung windows if your house has a stuffy atmosphere on a consistent basis or if you reside in a region that experiences high temperatures.

Upkeep and Tenant Management

When compared to single-hung windows, double-hung windows are much simpler to clean and maintain. Because the sashes of double-hung windows tilt inward, it is possible to clean the glass on both the interior and exterior of the window without leaving your house.

It’s possible that this won’t be a deal breaker when it comes to the single-hung windows on the first story house, but anything on the second story or higher will be difficult to clean. 

Costs

The cost of double-hung windows is typically higher than that of single-hung windows. Single-hung windows are typically the most cost-effective option when replacing existing windows with new ones. 

When compared to single-hung windows, double-hung windows can be up to 75% more expensive. In addition, the labor to install double-hung windows is more expensive. 

Installation

Installation of both single-hung and double-hung windows is easy. It can be done by homeowners too! However, professional wholesalers and contractors should offer the installation since advanced level carpentry is required to install these windows professionally.

Resale Value

The resale value of double-hung windows is greater than that of single-hung windows due to the fact that double-hung windows cost more and include more features. But in general, installing high-quality windows will almost certainly increase that home’s worth, particularly if the windows are designed to complement the house’s architectural style.

Concerning Health and Other Dangers

Double-hung windows can be a potential security danger if they aren’t closed and locked in the appropriate manner. If double-hung window is left open all the way, the higher sash can slowly slide down to the bottom of the window. 

This will prevent the window from locking, which could allow an intruder to enter your home. Before leaving the area, checks should be made to ensure the double-hung windows are thoroughly shut and locked, just as with any other type of window.

A home with young children and single-hung windows is another recipe for disaster when it comes to potential injuries. When the window is opened, it is simple for toddlers to get their hands on the bottom sash. This is a recipe for catastrophe if they are of a size that would allow them to pass through the opening.

Every window presents its own unique set of dangers. One can simply overcome them by following some basic precautions against potential danger.

Common Issues With Aluminum Double-Hung Windows

Here are three typical problems with double-hung windows and solutions for each.

Damaged Seal

During the cold weather, the windows may get fogged up and sometimes there is a smog that will not dissipate on its own. A tiny gap between the seal and the glass may develop as a result of the manufacturing process or impact damage.

Difficulty in Opening

Another common issue with aluminum hung-window is that sometimes the hinges attract dust and this makes it difficult to close or open the windows. However, lubricating the window hinges would help solving the issue. 

Chilly Windows

The window sashes around the weather stripping likely need to be replaced if they frequently feel a draft emanating from them. Energy-efficient windows would be required to halt the draft. 

How To Clean And Maintain Aluminum Double-Hung Windows

Double-hung windows typically require more upkeep than other kinds of windows. They do, however, have a number of benefits over other kinds of windows. For instance, these windows complement the majority of house styles. They come in a variety of hues, sizes, and materials.

However, cleaning them is pretty simple. When maintained correctly, they last longer. They are also energy-efficient in that they use less energy to heat and chill a house.

Cleaning and Maintaining Double-Hung Windows 

Every autumn and spring, clean the windows to allow for clear views of the backyard and allow you to check them for any issues carefully.

The cleaning advice provided below applies to plastic and wood, two of the most popular materials used to make these windows.

Apply the cleaning technique to any other window material if the frame material is not mentioned in some of the suggestions below. 

Screen Cleaning

Initially, take the screen out of the window frame. Dish soap and tepid water are combined. (mild option). You should dip a sponge into the concoction. Use the sponge to scrub the insect screen carefully.

To prevent damage, hold the insect screen cloth while cleaning it. Use tepid water to rinse it. Let it air for a while. Install it back into position after it has dried. 

Casing cleaning

The casing should be cleaned frequently to remove grime and debris accumulation that can cause the windows to stick.

To ensure that the sash operates without difficulty, vacuum any grime and debris that may have amassed in the sill and track. Any vinyl window components should be washed with water and a gentle detergent.

Tips For Installing Double-Hung Windows

The proper installation is essential to ensuring that all doors and windows will continue functioning properly and trouble-free for many years.

Before you begin, check that you are outfitted with the appropriate protective gear for the location where you will be operating and the instruments you will be using.

You will need the following instruments:

  • Drill with a bit measuring 3 millimeters, which is used for pre-drilling the holes for the fixings.
  • Hammering in nails or screwing in screws that are appropriate for your particular installation
  • Spirit level
  • Tape measure
  • Hammers\Packers
  • Tiny pinch bar
  • Screwdriver with a flat head
  • Staple gun and staples for flashing
  • A second set of hands to help out (depending on the size and weight of the product)

Before Installation

Measure the product’s height, breadth, and depth, as well as the aperture it will be installed into, before commencing installation.

To ensure a square and level installation, the opening size has to be larger than the product by 20 millimeters in width and 30 millimeters in height. Please refer to the sample that may be seen below about spacing requirements.

The total depth of the product must correspond to the kind of cladding it will be fitted into. This was likely decided when the goods were purchased; nonetheless, it does not harm to check more than once. You must also decide what kind of flashings are necessary for the job. While we provide a selection of typical flashings, the builder must choose how the structure will be made waterproof.

It is necessary to advance the flashing and secure it to the front face of the stud. A standard staple gun may be used to do this task.

It is a good idea to check again to see whether the product you are installing has any particular installation criteria that must be followed. They could include customized head heights, unique finishing elements, or the ability to match other items.

You may start the installation when all of the checks have been double-checked. 

Installing double-hung window

  • To begin, position the pack level where the product will sit on the bottom plate and the spirit level where it will rest. If packers are necessary, secure them using brad nails to ensure they do not slide about.
  • Make a mark on the reveal of both jambs one hundred millimeters down from the top and one hundred millimeters up from the bottom.
  • Use a drill bit with a diameter of 3 millimeters to create a hole in each mark.
  • Put the product in via the opening while it is still on the outside.
  • Overhang the reveal back into the house by 10 millimeters, using a 10-millimeter packer or the thickness of a basic brickies ruler as a reference. A conventional installation allows 10 millimeters of plaster to be applied inside.
  • Install a nail into the stud by driving it into the pre-drilled hole closest to the sill on both sides of the product.

Note: Do not completely hammer them in at this point.

  • Insert a nail into the hole pre-drilled at the very top of the reveal. Remember, you should not hammer it in completely. On the other side of the product, repeat the same sentence.
  • Check that the product is square and plumb by pressing your spirit level against the jamb while inspecting.
  • To ensure the product is square, measure it diagonally in both directions. Both dimensions should ideally be identical to one another. However, a difference of up to a few millimeters is considered acceptable.
  • Use the pinch bar to place the product into the appropriate position carefully if necessary.
  • Examining how the product functions before packing it and putting it away are important. To check that the sash is operating correctly, slide it open and back into the closed position.

Finishing  

When you are satisfied with the product’s location, pack between the reveal and the start above the nails, then hammer all the nails into place.
