Experience the Difference
Sapphire Windows uses world-class systems developed by Deceuninck. Our windows have been designed with emphasis on security and simplicity. Innovative hardware technology ensures that you are well protected against all elements, both natural and human.
The surrounding environment provides light, warmth and fresh air, and our windows are able to let these desirable elements in when required, yet remain secure and well insulated both thermally and acoustically when closed. The multi-chambered profiles of the window are the reason such insulations are realised, while the galvanished steel reinforcements located in the heart of the profiles ensure strength and security of the windows.
Glazing options are available from 6mm to 31mm, with the type of glass an option to you. Choose either single glazed float glass, double glazed, tempered or laminated glass to suit your needs.
Absolute Top in Insulation
Engineering tests carried out in Germany have shown that our windows are able reduce sound transmittance (soundproofing) and achieve a maximum Sound Transmission Class (STC) of 38dB. A maximum heat transfer coefficient U=1.6w/m2K is also possible, which is up to 4 times better than traditional aluminium windows. View our real world acoustic test at the bottom of this page!
