With energy bills and the cost of living continuing to increase, it’s essential to find ways to lessen the amount of energy we use every month. Replacing old installations with newer energy efficient windows can help reduce the amount of energy wasted within a home.

But where can you find the best energy efficient windows for your customers’ homes?

At Quickslide, we manufacture highly energy-efficient windows, including sliding sash windows, casement windows, and flush casement windows. With almost years of experience, we have evolved our expertise of sliding sash windows into products that can offer some of the best energy efficient windows on the market in the UK.

Incredible Thermal Performance

Our uPVC sliding sash windows have a window energy rating of ‘A’, which means they can offer great thermal performance. They come with a u-value of 1.4 W/m2K and a built-to-last double glazed glass unit sealed to withstand the worst the UK weather can throw at them.

Within the 24mm double glazing you’ll find a layer of argon gas and because argon is a heavy atom, the atoms don’t move very fast, and the gas is therefore considered as a poor conductor of heat. We use argon as another measure for great insulation. uPVC is considered by many as better at retaining heat than other window materials, and the multi-chambered profile ensures that every part of the window is designed for optimal warmth and comfort. 

Our sliding sash windows come standard with a unique slide and tilt function, letting homeowners tilt both the bottom and top sash inwards, so come the warmer months, homeowners can enjoy the warm weather to the max. This function is also ideal for cleaning the window from inside the home. 

Durable Design

The best energy efficient windows don’t just have double glazing, low U-values, and great energy ratings; they also must be tested to the British weather condition standards to prevent leaks and cold draughts. At Quickslide, our uPVC sliding sash windows surpass the standards and come with high-quality integral window cills to stand firm against intense weather conditions.

Additionally, the wool pile strips that feature across our range of sliding sash windows are available in multiple colours to blend in seamlessly with the rest of the window, meaning customers won’t have to compromise on style for optimal weather performance.

The trickle vents included across our energy efficient sliding sash window range can blend in with the rest of the frame, providing excellent air ventilation even while the windows are shut. Please note, trickle vents are now required by law on most windows across the UK.

Modern Security Features

Double glazing isn’t just helpful in creating the best energy efficient windows, but also for improving the security of a home. Having twin panes makes the glass more energy efficient as well as robust and harder to break through. All our windows, including our sliding sash window range, come with leading locking mechanisms and the full window can be upgraded to a comprehensive high security PAS 24 package which meets the latest building regulations and requirements for enhanced security. Please note PAS 24 is required on new buildings.

Homeowners can have peace of mind when you choose Quickslide for some of the best energy efficient windows on the market.

Authentic Sliding Sash Windows

The uPVC sliding sash windows we manufacture are designed to combine the best energy efficient technology with classic sliding sash design. Our uPVC windows can be upgraded to mechanical joints, combined with our woodgrain foils, to create a totally authentic traditional style. These mechanical joints replace the 45 degree welds with 90 degree joints that mimic the appearance of conventional timber joints.

Alternatively, we also offer seamless welds for a cost-friendly but still totally uninterrupted finish across the whole window profile. Your customers can enjoy all the benefits that only the best energy efficient windows can provide without compromising their home’s original and unique aesthetic.

Customisable Colours

At Quickslide, our uPVC sliding sash windows are very energy efficient and can also be customised to suit almost any property style. Our extensive range of finishes is designed to last and to be exposed to the British weather, so homeowners won’t have to worry about the durability of their window finishes for years to come. Even traditional style homes can benefit from our modern performance sliding sash windows with our authentic woodgrain foils that can mimic the appearance and feel of classic timber frames.

We also offer dual colourways, providing a mixture of styles for both outside and inside a property. Whether you’re looking for a natural agate grey or a bold anthracite grey, our energy efficient windows can suit your needs.
