Savings
Up to 80% more affordable than regular double glazing.
Insulating your home shouldn’t cost the Earth.
Gecko allows you to keep your existing windows while feeling the benefits of double glazing, costing you less time and money.
Efficiency
Lower bills, same charm.
Gecko Panes seamlessly blend in without affecting the appearance of a traditional, wooden sash window. You won’t know they’re there, until you check your bills.
Performance
We rely on science.
Gecko Panes trap a layer of air, turning it into a strong insulator, which reduces escaping heat and emissions by up to 50%.
This improves your Energy Performance Certificate (EPC) while delivering enhanced comfort and savings.
With a sustainable, eco-friendly approach, Gecko Panes help save tonnes of CO2 annually and reduce noise by 25%.
Installation
Gecko Panes fit 99% of windows.
We designed Gecko Panes to slot into almost every wooden sash window.
Our patent pending sponge surround means each pane is fully removable and installed without drilling any holes for additional fittings or clips, preserving the look for heritage homes.
A community you can trust.
