With over 20 years’ experience, C-THRU WINDOWS, DOORS & CONSERVATORIES LTD have been producing UPVC windows and doors for thousands of satisfied customers in the East Sussex area. Our uPVC windows are made using cutting-edge technology, ensuring that they not only look amazing but also perform well in terms of heat retention, weather resistance, and security.
Unplasticized Polyvinyl Chloride, or UPVC, is a cost-effective building material that is commonly used as a substitute for painted wood when replacing older single-glazed windows. UPVC is the first-choice material in the double-glazing home improvement market due to its strength and durability. To comply with strict Building Regulations, all UPVC windows and doors must be energy certified. They also come in a variety of appealing colours and woodgrain timber finishes.
