Further Detail The YardLITE Pine and YardLITE Pine Vented roof windows are made from high quality raw materials: FSC certified pine wood that comes from sustainable forests. The glass pane has a Ug-Value of 1,1 W/m2K and has 24-mm double glazing (argon filled), a low E coating and a toughened outer pane. The toughened outer pane prevents the glass breaking in the event that it is hit by something from outside. The low-E coating allows light into the room, and at the same time, reflects heat from outside out of the room, keeping the room cool in the summer. It also traps the heat on a cold day thereby keeping the room warm. The “slimline” design gives a modern look from the inside of the room. This unique design by YardLITE also allows up to 10% more daylight in (than some other branded windows). The high quality moulded zinc handle allows the window to be locked in three positions; for passive ventilation on demand or to close the window. In addition the YardLITE Pine Vented provides a ventilation valve that allows airflow into the room even when the window is closed, so that when you’re not at home, you can still ventilate the room. Installing YardLITE windows is easy. Just follow the tried and tested procedure which is clearly set out in the installation guide included with every window.
