Profile: Kitson Trade Windows Ltd. manufactures and installs PVCu products, including windows, patio & french doors, conservatories, roof & porch canopies, sealed units, secondary glazing and roofline products. We design and manufacture PVCu vertical slide sash style windows that are extremely strong and durable windows with interlocking sashes for increased security and perfect weather sealing, with both insulation, soundproofing and solar PV cells. Our patio doors can be tilt and slide or straight slide patio master doors. They allow maximum light into the room, and allow easy access, combining well engineered smooth operation with high security. The unique tilt and slide action allows the patio door leaf to tilt inwards to provide ventilation without compromising security.
