Em-Domes are quality thermoformed rooflights, designed to make optimum use of natural light.
They are offered in a wide range of sizes, shapes and glazing options to meet virtually any specifier and client requirement.
Light transmission - 77%.
Solar heat gain factor - 69%.
Sound reduction (db) - 20.
Thermal transmission (w/m2k) - 2.68.
High security screwbolts
Unique to the Em-Dome are the patented high security screwbolts, supplied factory fitted as standard to all units.
Once installed, the fixing cannot be removed using common tools.
The screwbolt provides a high level of resistance to tampering or forced entry.
The fixing screw or bolt is sleeved within the body of the screwbolt which avoids pressure being exerted on the rooflight glazing as the fixing is tightened.
This virtually eliminates the risk of stress fractures caused by over-tightening.
Thermoformed Glazing
Em-Domes are thermoformed from polycarbonate sheet and are available in single, double and triple skin plus certain sizes available in quad skin or Eco multiwall construction.
Polycarbonate is virtually unbreakable, with an impact strength up to 250 times greater than glass.
Glazing Options
Em-Domes can be supplied in clear, opal diffused, bronze or ‘Heat Reflect’ (which reflects up to 68% of the heat radiation) glazing.
All polycarbonate Em-Domes have a minimum 3 mm thick glazing.
Acrylic Em-Domes have a minimum 3mm outer skin.
Inner skin thickness varies according to the dome size.
