Door Glass Glazing System Options



R-Value reflects properties of the glass only. Center of glass calculations are based upon software from Lawrence Berkeley National Laboratory.

Depending on the region in which you live, you’ll want door glass that keeps cold out and prevents heat from leaving your home in winter and keeps heat out and air conditioning in during the summer. 

ProVia’s ComforTech™ Warm Edge Glazing System is designed to do just that.  Combined with a high R-value, double- or triple-glass unit, insulating chambers filled with Krypton or Argon gas and Super Spacer®, ComforTech improves the comfort and energy efficiency of ProVia’s doors.   Our ComforTech system is available in seven options, including high-performance Low E glass and increased UV protection.  All ProVia doors with glass using ComforTech DLA-UV are ENERGY STAR qualified for all climate zones.  Use our Energy Performance Calculator to determine which other glass and glazing combinations qualify for ENERGY STAR rating in your region.
