What is a mock sash uPVC window?

mock sash upvc windows with upvc sash horns

Mock sash uPVC windows are a popular choice among UK homeowners who want the classic look of a traditional sliding sash window without the high maintenance, energy efficiency and higher costs of the original design. 

The term "mock sash windows uPVC" refers to the fact that the window appears to be a traditional uPVC sash window, but in reality, it is a modern uPVC casement window. You might also find these windows referred to as fake uPVC sash windows, faux sash, and dummy sash.

These mock windows are the best of both worlds because although they look like sash windows that slide vertically, they actually function as casement windows which open outwards. 

Mock sash windows also come in other materials such as timber and aluminium. However, mock sash windows made of uPVC are the most common. uPVC windows are known for being durable, energy efficient, and cost-effective.

What is the difference between traditional sash windows and mock sash windows?

Although mock sash windows are designed to replicate traditional sash windows, there are still some distinct differences. The most prominent difference is the opening mechanism. 

Whereas the original sash window has two traditional sashes which open vertically on sliding rails, the mock sash window's opening mechanism is more similar to a casement window. That is, mock sash windows usually have one sash that tilts open like a standard casement window and a fixed pane.

uPVC sash windows are known to have a distinctive look, with two sashes made up of multiple glass panes separated by small wooden bars, known as glazing bars and exterior uPVC sash horns. While mock sash uPVC windows come close to replicating the original design, their exterior is not as authentic as actual uPVC sliding sash windows when viewed closely. 

Benefits of mock sash uPVC windows

Apart from the aesthetic appeal, mock sash uPVC windows offer numerous benefits for your home. In this section, we'll explore the advantages of mock sash uPVC windows, including increased energy efficiency and reduced maintenance costs.

1. Increased energy efficiency

In terms of energy efficiency, mock sash windows are often considered superior to traditional sash windows. This is because they are designed with multi-chambered frames and low-emissivity glass, which helps to keep heat inside the home and reduce your energy bills.

In contrast, traditional sash windows can be prone to draughts and heat loss, which can make them less energy-efficient. You can also increase energy efficiency simply by double glazing or triple glazing your mock sash windows.

2. Lower energy bills

Because mock sash windows made of uPVC provide good insulation and retain a lot of heat it means you'll need to spend less money on energy to regulate your home's temperature. This makes them an excellent choice for homeowners who want to reduce their carbon footprint and save money on heating and cooling costs.

3. Weatherproof

Mock sash uPVC windows are an excellent option for those seeking enhanced weather resistance. uPVC windows are highly resilient to weather-related damage and do not rust or corrode, making them a durable long-term solution. Moreover, many mock sash windows come equipped with compression seals and stormproof hinges, which improve their draught-proofing capabilities. 

Additionally, if your mock sash window operates like a lipped casement, featuring sashes that close and overlap over the frame, it provides an additional layer of protection against unpredictable and wet weather conditions.

4. Easier maintenance

Mock sash uPVC windows are easier to clean and maintain than traditional sash windows because the bottom sash of a mock sash window usually has a tilt function, allowing it to be easily cleaned from inside the house. 

Meanwhile, traditional sash windows can be difficult to clean, as sometimes single-hung windows require the removal of the takeout clips and double-hung windows can require the removal of the sash from the frame in order to access the glass.

5. Many style and colour options

Mock sash uPVC windows come in a variety of styles and colours, making them a versatile option for any home. For instance, you can improve aesthetics by getting white, black, or even grey uPVC mock sash windows.

They can be designed to match the existing windows on your property, or to provide a contemporary contrast to a traditional design. Many homeowners also choose to add decorative features, such as Georgian bars or uPVC sash horns, to enhance the aesthetic appeal of their mock sash uPVC windows.

6. More affordable

uPVC mock sash windows are often considered a more affordable alternative to traditional sash windows. This is because they are designed to mimic the appearance of traditional sash windows –which are usually made of timber– while using cheap yet sturdy materials, such as uPVC. Also, mock sash windows are usually less complex to manufacture and install.
