Aluminium is in a class of its own when it comes to energy efficiency thanks to its capacity to be repeatedly recycled while retaining its unique qualities. The nature of this material is such that many technically developed industries such as aircraft construction utilise its lightweight properties. The uses of aluminium are numerous not least in the area of double glazing, it gives itself easily to unusual shapes in a number of thicknesses and can be coloured with RAL or BS powder coatings in many shades. TWS offer an excellent range of aluminium double glazed windows in addition to UPVC replacement windows, doors, bi-fold & multi-fold doors, conservatories and orangeries. FENSA registered TWS are also specialised in manufacture and installation of secondary double glazing, a concept which due to its specifications of slimline strength makes aluminium a perfect material.
