BULLET-PROOF WINDOWS AND DOORS
When you need the highest levels of security, anti-burglar qualities and weather resistance, choose the CS77 door from Prestige Aluminium Bi-Folds in Bootle, Liverpool.
The ConceptSystem 77 collection
CS77 is a thermally broken, multi-chambered system for windows and doors that offers excellent levels of security, weather resistance and thermal insulation.
Some extreme situations require bullet resistance, and this variant offers it in various classes. However, it is just as suited to residential settings as it is to high-security commercial ones.
The CS77 system offers a comprehensive range of inward-and-outward-opening window and door designs, which come available in three different styles, making it an incredibly versatile choice for any setting. Choose from a variety of colours and finishes – you can even have a different colour inside and out!
The fibreglass-reinforced polyamide strips and weather gaskets are designed with ribs and hollow chambers to achieve superior thermal insulation levels.
