We have manufactured the market leading Spectus vertical slider for over twelve years, for more information on the specification of this Traditional UPVC sash window profile system please see our downloads section.
A Sash Window or more commonly Vertical Sliding Sash Window provides all the benefits that a 21st century window should do, combining technology and improvements in thermal efficiency delivering better performance than the age old tradition sash windows, offering a long term, cost effective solution for period style properties in conservation areas, new build properties and buildings which you would not even expect, especially with the new range of real wood effect foils on offer. The PVCu window frames have been designed to provide optimum strength, superior thermal properties and excellent weathering performance whilst retaining their pristine appearance year after year with the minimum of maintenance.
Manufactured from a formulation which includes a high impact modifier to withstand cold weather and a UV light resistant pigment to maintain colour and appearance for years to come, the profile will not degrade, bend or warp.
Structural strength is enhanced through the use of steel or aluminium reinforcement through the internal chambers of the profile. To further increase stability and strength all fixings and hardware are secured to this reinforcement.
