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.
