Key Features

Thermal Efficiency

Our sliding sash windows not only meet but exceed building regulations. With the multi chambered uPVC profile, our casement windows have *U-values from 1.3W/m²K.

*The U-Factor, also known as the thermal transmittance, is a crucial metric for evaluating a window’s insulating capabilities. It quantifies the rate at which heat transfers through the window assembly. Lower U-Factor values indicate superior thermal performance, meaning the window is more effective at maintaining comfortable indoor temperatures.

Environmentally Friendly

SFX Trade is committed to sustainable practices. Our casement windows are crafted from lead-free uPVC, minimizing environmental impact during their production. Furthermore, these windows are 100% recyclable at the end of their lifespan, promoting resource conservation. By choosing SFX Trade, you contribute to a more sustainable future.

High Security Locking System

We prioritise the safety and security of your home. Our casement windows incorporate a robust shoot bolt locking system, offering exceptional protection against unauthorised entry. For added peace of mind, we also provide the option to integrate child restrictors into the windows, ensuring the well-being of your loved ones.

Customisation Options

Our sliding sash windows come with the optional hardware including sash lifts, pole eyes and tilt knobs. Simply get in touch with our team to specify your requirements and we’ll take care of the rest.

What is the difference between the window frame and sash?

The sash is the component of the window which holds the glazing and keeps it in place. The sash is designed so your window can be more air tight and less prone to draughts. In contrast, the frame holds the sash and the rest of the window in place. With our sliding sash window frames, they can be customised to arched or swept head specifications.

How popular are sash windows?

Sliding sash windows are a very popular choice among homeowners in today’s housing market. This is due to their practicality and excellent flexibility. These windows are suited to most homes. With their wide range of customisation options, it is no wonder they are a popular choice

As well as a vast selection of RAL colours, woodgrain or foil finishes, your customers will also have the option to choose from sculptured and chamfered options. The sculptured option creates a decorative vintage feel and greatly suits a home with older architecture. The chamfered choice is more modern and sleek, perfect for new builds and those going for a contemporary look.

What homes do sash windows suit?

Sliding sash windows are popular due to their traditional look. Homeowners with heritage houses tend to lean towards a more classic look when upgrading their windows. These windows are also well known for their excellent ventilation and insulation through the use of components such as trickle vents, which makes them a perfect choice to combat British summers and winters. 

How long do sash windows last?

Since our sliding sash windows are made from uPVC, they typically have a long life span of 20+ years. However, with little maintenance and care, your customers could see their windows lasting much longer. If you require more information on sash window maintenance, please contact us to find out more.
