Where and When to Use Each Heat Mirror Product

All Heat Mirror products block 99.5% of the ultraviolet radiation to slow the rate of fading.

• Substantially improved insulation over standard, double-pane insulating glass. 
• Low reflectance; highest light transmittance (north and east side of structures). 
• Passive solar structures where solar heat gain is desired (south and west side of structures).

  Examples:

  1. Residential projects where insulation is the primary concern and for "view" homes.
  2. Smaller commercial or institutional projects where low reflectivity is desirable

Heat Mirror TC88:

• High insulation - (Coating on both sides of film) U-Value = .21 vs. .26 over HM 88. (1/8" glass, air filled, 1" overall).
• Greatest transparency -  less reflective than HM 88.
• High light-transmittance.
• Color neutral.

  Examples:

  1. Residential - improved insulation over HM 88 with or without gas filling.
  2. Commercial - any project needing improved insulation and minimum reflectance such as retail storefronts, restaurants, airports, schools, hospitals, museums, historic renovations.

Heat Mirror 77:

• Improved Solar Control with minimal reflectance and high light transmittance.
• Less Reflectance  than HM 66.

  Examples:

  1. Residential - view homes with a south or west orientation.
  2. Commercial - any project needing additional control of heat gain with minimal reflectance. 

Heat Mirror SC75:

• Excellent Solar Control with minimal reflectance and high light transmittance.
• Less Reflective  than HM 66 but with similar shading performance.

  Examples:

  1. Residential - view homes with strong need for control of heat gain and good insulation.
  2. Commercial - all types of projects where a reflective glass appearance is undesirable but solar control is necessary.

Heat Mirror 66:

• Stronger solar control but non-reflective enough to meet City of San Francisco code requirements. 
• Residential or commercial product needing solar control and insulation WITH low reflectance.

  Examples:

  1. Residential projects  with south or west-facing glass.
  2. All types of applications with strong need for clear solar control but minimal reflectance such as: schools, hospitals, museums, libraries, vertical portions of solariums and conservatories, smaller skylights.

Heat Mirror 55:

• Moderately reflective, high light transmittance. 
• Vertical and sloped glazing for commercial projects needing stronger solar control without losing visible light.

  Examples:

  1. Office buildings needing clear glass.
  2. Sloped glazing needing good light transmittance (solariums).
  3. Small to moderate-sized skylights.

Heat Mirror 44:

• Reflective, but with high light transmittance. 
• Sloped glazing or commercial projects where reflectivity is not an issue but needing stronger solar control.

  Examples:

  1. Sloped glazing for skylights, atriums, or conservatories needing a favorable light to heat ratio.
  2. Projects needing a very high light transmittance versus solar control.
  3. Often used with tinted glass for vertical applications.

Heat Mirror 33:

• Reflective, high light transmittance where maximum solar control is needed. 
• Sloped glazing or commercial projects where reflectivity is not an issue but control of glare is desired.
• Can be combined with tinted glass for excellent solar performance and daylighting.

  Examples:

  1. Large commercial skylights and all types of overhead glazing needing strong solar control and glare reduction.

Heat Mirror 22:

• Highly reflective exterior appearance - maximum solar control. 
• Sloped glazing projects where reflectivity is not an issue.

  Examples:

  1. Wide use in solariums for maximum solar control and insulation in sloped glazing.
  2. Large skylights
