Alu-wood Folding Sliding Doors

Alu-wood products offer even further qualities and advantages over just the timber or aluminium alternatives. Alu-wood simply incorporates all of the winning credentials and combines them to. give the very best u-values, thermal efficiency, performance, beauty and wow factor

Aluminium is extremely lightweight and strong, which is one main factor when it comes to the width of the frame profile, in addition to its durability and minimal maintenance when compared to other materials. The Sunflex 50c, 55c and SF75c provide all the same benefits as their SF50, SF55 & SF75 donors but with the natural beauty and warmth of a timber frame to the inside. The high performance, longevity and thermal properties of thermally broken aluminium with the refinement of timber to the inside, provides the very best of both worlds…

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.
