The RoofLITE Slim Vent centre pivot window has a reduced width Slim frame, which gives the window a contemporary look when viewed from the inside. Manufactured using FSC certified wood, the RoofLITE Slim Vent roof window is fitted with a ventilation valve ensuring an inflow of sunlight and fresh air, making it a great way to bring extra light into your loft. Despite its reduced frame width, the Slim Vent provides a high thermal insulation parameter whilst its glazing unit, featuring a toughened pane, makes it highly durable in all weather conditions, including hail. The Slim Vent centre pivot window has a centre pivot (hinges mounted at half window height) together with a handle at the base of the frame, making the window easy and convenient to use at any installation height. The window's handle has two ventilation positions, as well as a ventilation valve installed into the upper part of the sash, which allows an inflow of fresh air into the room without the need to fully open the window. RoofLITE Slim Vent windows must be installed using a dedicated installation flashing kit, which ensures 100% tightness of fit between window. The flashing must be selected in accordance with the roofing material. Why choose RoofLITE? All RoofLITE windows are manufactured in Europe, ensuring high production standards and quality control.
