Aluminium Folding Sliding Doors

Aluminium is renowned for incredible strength and lightweight construction making it a highly versatile material. With the market quickly moving away from the traditional UPVC, aluminium provides an almost incomparable structural stability, life expectancy and integrity whilst maintaining minimal, sleek and stylish sightlines. Unlike aluminium years ago the ability to achieve excellent thermal qualities when separated by a polyamide insulation strip makes it undoubtedly the material of the future. Excellent U-values can now be achieved without compromise to. With over 200 RAL finishes and even dual colour available aluminium can now be tailored like never before.

Laboratory tested

You should only trust systems that have been fully tested and certified. Gaskets that have been tested to provide a weather rating, do not actually mean the system itself has been tested and brush piles on their own are not an effective seal. The Sunflex range of systems together with the individual components have been motion tested in a laboratory controlled environment over 20,000 times. They have been subjected to many vigorous tests including prolonged air pressure and water permeability in order to be certified and carry the CE stamp of approval.
