Timber Folding Sliding Doors

All Sunflex timber systems are strengthened and stabilised by a process of lamination, often referred to as engineered timber. This is where the timber is separated into three solid sections and bonded back together with opposing wood grains, creating a timber with greater durability and stability. The resulting strength of this process combined with the fibrous make up of the timber ensures minimal framework and a lifetime of continued reliability. In addition to this are the timbers superior thermal qualities.

All timber used during manufacture is sourced from sustainable forests and produced in some of the most eco friendly factories across the world. The standard available timbers are knot free Nordic pine and Meranti hardwood although other special timbers such as European oak and mahogany are also available by special request.

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.
