UPVC Windows & Doors


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.

With energy bills at an all-time high, UPVC windows are the way to go when it comes to saving money.

Energy-rated UPVC windows are incredibly energy efficient. Because of the materials used in production, they have an extremely low thermal conductivity. This prevents heat from escaping as easily as it might with other types of construction materials.

All our double-glazing products are built here in the UK, and we utilise the best window materials to ensure the highest level of quality and security. All our windows and doors are sturdy, reliable and long-lasting.
