Weatherlock uPVC Windows and Doors are manufactured FREE of BPA’s so there is no fear of contamination. uPVC, unplasticized Polyvinyl Chloride, is an environmentally friendly material. Our uPVC manufacturing material is certified for use in medical and dental equipment.
Not only do Weatherlock Windows and Doors lock out weather, heat, cold and humidity, they are also extraordinarily soundproof. The perfectly calibrated manufacturing process provides a natural sound barrier to make your interior environment quieter. Weatherlock Windows and Doors will not rattle on windy days and the same thermal insulation barrier that locks out weather acts to buffer exterior sounds.
