RoofLITE+ SOLID VENT AVY B900
A reinforced frame together with a ventilation valve Learn about all of the advantages of SOLID VENT.
RoofLITE+ SOLID VENT windows are centre pivot windows (hinges mounted at half window height) manufactured from sustainably sourced pine wood that has undergone an impregnation process during production, ensuring that it remains durable and robust over many years.
The SOLID VENT window is set apart by a reinforced frame and a ventilation valve built into the upper part of the sash. The first ensures high insulation parameters and resistance to the most adverse weather conditions, including intense rain and strong winds. Meanwhile, the ventilation valve provides increased comfort for everyday use.
The SOLID VENT is double-glazed with two low-emission (heat reflective coatings) which prevent heat loss in the winter, in addition to a toughened external pane that ensures the RoofLITE+ SOLID VENT is a window ready to face all conditions.
A handle mounted at the base of the sash ensures convenient operation at any installation height. The handle has two ventilation positions which allow an inflow of fresh air into the room without the need to open the window.
Like all RoofLITE+ windows, the SOLID VENT AVY B900 is covered by a 10-year guarantee (provided that it is installed using an original RoofLITE+ flashing).
When selecting a RoofLITE+ roof window, don't forget to explore our range of dedicated accessories that make daily use more comfortable. We especially recommend our set consisting of a DUA blackout blind in combination with an MIA external antiheat blind. This guarantees both privacy and protection from overheating for your room.
