TECHNICAL DATA

GLAZING OPTIONS
All Artistic Skylights are available with either domed, pyramid or flat acrylic glazing, or flat glass glazing. Acrylic glazing is available in three colours:1.CLEAR– recommended when the maximum amount of light is desired.2.WHITE 2447–translucent material used for light diffusion, reduced heat and glare, and privacy.
3.BRONZE 2412–transparent material used to reduce interior solar heat gain, control glare, and prevent bleaching of furnishings while permitting clear vision to exterior.

SPECIAL ACRYLIC COLOURS: A wide range of transparent and translucent acrylic colours are available for special effect. Consult with Artistic Skylight Domes Ltd. for special acrylic colours.
INSULATION(U VALUES)
Plastic glazing has one fourth the thermal conductivity of glass, therefore giving it an insulation value of approximately 20% better than standard glass.(Please see Energy Efficiency Table for plastic glazing u-valves below) The recent advent however, of specialty glass such as low emissivity and reflective mirror glass has drastically improved the insulation and heat transmittance of glass.
