Description

Enjoy the comfort of double glazing—without replacing your timber windows or doors. 🪟🚪❄️

Love the look of your classic awning, casement, or French doors—but hate the draughts, condensation, and noise? DIY ecoGlaze On Sash is a discreet, high-performance secondary glazing solution designed specifically for hinged windows and doors. It allows you to retain the charm of your existing timber frames while gaining the thermal and acoustic benefits of double glazing.

Frequently Asked Questions

What is ecoGlaze, and why is it a good alternative to double glazing?

ecoGlaze is a secondary glazing system that gives you many of the same benefits as double glazing—better insulation, reduced noise, improved comfort, and lower energy bills—without replacing your windows. It works by adding a clear acrylic panel to the inside of your existing window, creating an insulating air gap that helps keep your home warmer in winter and cooler in summer.

Do I have to replace my windows to use ecoGlaze?

Not at all! That’s the beauty of ecoGlaze. It works with your existing TIMBER windows—no need to rip anything out. It’s a much easier, more affordable way to get the benefits of double glazing without the cost or construction mess.

Will ecoGlaze change how my windows look?

Nope! ecoGlaze is designed to be discreet and neat. The acrylic panels are crystal clear and the frame options (timber or white aluminium mouldings) blend in beautifully. Once it’s installed, you’ll hardly notice it—apart from how much more comfortable your home feels.

Can I install ecoGlaze myself?

Yes! ecoGlaze is a DIY-friendly solution with clear instructions and step-by-step videos to guide you through the process. If you’re handy and confident with a measuring tape, it’s a satisfying weekend project.  If you could prefer for an ecoGlaze installer to install for you  please contact us for a referral to a trusted ecoGlaze technician in your area.

How do I know which ecoGlaze kit I need?

That depends on your window type! We have kits for fixed windows, sash/hinged windows, and even ready-to-go standard sizes. If you're unsure, our friendly team can help you pick the right kit for your window style.

The kit worked well. Installation required care. I have a decent collection of tools that made it easier looks good and can tell the reduction in heat flow.

Hi Clive,

We're delighted to learn that our DIY ecoGlaze kit worked well for you and that you were able to see a reduction in heat flow. We understand that installation can require care, as it is a multi-step install it is something that a moderately competant DIYer should undertake. We are happy to hear your collection of tools helped with that. Thank you for your support and sharing your thoughts with the community.
