What is a uPVC Sash Window?

A uPVC sash window consists of two glass panels that slide vertically thereby allowing for better airflow. The word “sash” refers to a frame that holds the glass. A sash sliding window typically features two sashes that slide up and down.

Our vertical sliders are stylish, safe and secure, and made of quality components. What’s more, they are easy to clean and low maintenance. If you are looking for a traditional look to suit your home, we can fit your sash windows with Georgian bars or even astragal bars before finishing them with sash horns for that added character.

Featuring a UPVC profile, our sliding sash windows are easy to maintain, energy-efficient and extremely durable. Whether you are looking to replace the existing windows in your period building or looking to add character to your new build project, our UPVC sash windows are a wonderful choice.

Sash Window Frame Colours

When it comes to sash window frame colours, the choice is as diverse as the preferences of homeowners. In South Wales, the most popular colour for sash window frames remains classic white. The timeless elegance and versatility of white frames seamlessly blend with a wide range of architectural styles, making them a preferred choice for many. However, there is an emerging trend towards incorporating light greys and greens into sash window designs.

These subtle yet refreshing hues add a touch of contemporary sophistication to homes, creating a harmonious connection with the surrounding natural environment. Light greys exude a sense of understated modernity, while greens evoke a calming and organic ambiance. With their increasing popularity, light greys and greens have become sought-after alternatives to traditional white frames, allowing homeowners in South Wales to infuse their personal style and enhance the visual appeal of their properties with these subtle and stylish color choices for their sash window frames.

Anthracite Grey Sliding Sash Frames

Anthracite grey sliding sash frames offer a modern and stylish twist to the classic sash design. The anthracite grey colour exudes a sleek and contemporary aesthetic, creating a striking visual impact that enhances the overall appeal of any home. These windows combine the timeless charm of period style with the on-trend colour choice, adding a touch of sophistication and character to both traditional and contemporary architectural styles.

The anthracite grey hue provides a versatile backdrop that complements various exterior colour schemes, allowing homeowners to create a cohesive and visually appealing look. With their sleek lines and eye-catching colour, anthracite grey sliding sash windows are a popular choice for those seeking to make a bold statement and elevate the overall aesthetic of their living spaces.

5 star review (1)

I could not be happier with the installation of my UPVC sash windows and the entire service from Heath Windows. The product itself looks great and authentic, and also the cost surprisingly competitive. I always struggle with trusting trades implementing work to a high standard, but Heath Windows, James, Richie and Mark went out of their way to do everything they could to achieve what I wanted, and they did it. I was also so great to see and hear their pride in the company they work for. I could not recommend Heath Windows enough to anyone wanting windows installed with quality and service at a great price. Honestly my windows just make me so happy.

Can you have uPVC double glazed sliding sash windows in conservation areas?

UPVC sliding sash windows can often be installed in conservation areas to replace timber sash windows. However, it is important to note that the guidelines and restrictions regarding window replacements can vary between different conservation areas and local planning authorities.

Conservation areas are designated to protect and preserve an area’s historic and architectural character, so any alterations or replacements, including windows, may be subject to specific regulations and requirements.

When considering uPVC sliding sash windows in a conservation area, it is advisable to consult with the local planning authority or a conservation officer. They can guide the specific criteria and guidelines that need to be met for window replacements in that particular area.

Some conservation areas may have strict guidelines that dictate the materials, design, and colour options for replacement windows to ensure they are in keeping with the area’s historic character.

In cases where uPVC sliding sash windows are allowed, it is essential to choose a design and finish that closely resembles traditional timber sash windows to maintain the visual integrity of the conservation area.

How secure are uPVC sliding sash windows?

Our uPVC sash windows are designed with robust security features to provide homeowners with peace of mind. These windows incorporate multi-point locking systems, which engage several points around the sash frame, ensuring a high level of resistance against forced entry.

The locking mechanism secures the sash firmly in place, making it extremely difficult for intruders to gain unauthorized access.

The use of internally beaded glazing prevents the removal of glass from the outside, further enhancing the security of the windows.  These security features are designed to exceed industry standards and provide homeowners with a reliable and secure solution for their window needs. With our uPVC sash windows, you can have peace of mind and confidence in the enhanced security measures that help protect your property and loved ones.

Traditional Style uPVC Sash 

The sliding sash window is popular in Cardiff, Swansea and Newport due to the large number of traditional-style homes. Usually, if a home already has white sash timber windows with concrete supports, it makes sense to replace them with modern-style white sash uPVC. The modern sash double glazing combines the benefits of traditional style with superb energy efficiency. We’ll be happy to discuss options with you if you want a different colour or to replace your sash windows with a different style such as casement windows.
