Typically most UPVC windows and doors will come in white. However, developments in the manufacturing process have meant homeowners are no longer limited to not only color but a series of customizable shapes, styles and imitation effect. UPVC is a low conductor of heat meaning when fitted correctly it will form a closed air system minimising the heat experience by non-insulation materials. While UPVC can stand up to the weather and requires less maintenance than naturally occurring counterpart materials.
