The RoofLITE+ TRIO PVC is a window with a centre pivot, manufactured from white PVC that is reinforced internally  with steel profiles.

The TRIO PVC is set apart by its wide, reinforced frame, triple glazing, and  enhanced moisture resistance. The first guarantees resistance to the most  adverse weather conditions, including intense rain and strong winds. Meanwhile,  the window’s triple glazing guarantees outstanding thermal insulation  parameters, with a Uw value of 1.1 W/m²K, while its PVC structure means that the  window requires virtually no regular maintenance, and makes the window surface  exceptionally easy to keep clean.

The TRIO PVC is triple-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+ TRIO PVC is a window ready to face any  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 every RoofLITE+ window, the TRIO PVC APY B1500 is covered by a ten-year  guarantee (provided that it is installed using an original RoofLITE+ flashing).
