A skylight can give your home day lighting and ventilation.
Skylights are situated on the rooftop, so they can bring about undesirable late spring sunlight based warmth gain and wintertime heat loss. GTEPL uses different coating technologies on the glass to reduce these effects, including heat-retaining tints, protected coating and low-emissivity (low-e) coatings.
Skylights can provide ventilation as well as light. Ventilating a building with an operable skylight releases the hot air that naturally accumulates near the ceiling. Ventilating skylights usually open outward at the bottom, and some units vent through a small, hinged panel. Skylights may be opened manually with a pole, chain, or crank.
Skylight glazing is usually either polycaronate sheet or glass, although other glazing technologies may be used for solar heat control. Depending on the performance you expect from a skylight, you may choose different types of glazing for different skylight locations throughout your home.
