First let's dispel the
myth. Heat Mirror is not a highly reflective product like the
"mirror" in its name might suggest. Heat Mirror consists of a
family of window insulation materials that are transparent to light,
but highly reflective to heat.
The best way to remember how this technology works is that Heat Mirror
reflects HEAT back to its source; to the outside in
the Summer when you want to reject it, to the inside in the Winter when
you want to retain it. Refer to Application
Guide Section - what to use where for use suggestions.

HEAT MIRROR® INSULATING GLASS
|
|
|
Heat Mirror® is
a low-emissivity coated film product suspended inside an insulating
glass unit. The result is a triple unit with two airspaces without the
weight of triple insulating glass and with far superior insulating and
shading performance. There are many different Heat Mirror® coatings: HM
88, HM 77, TC88, SC75, 66, 55, 44, 33, and 22. These
range from the low reflectance, high-light transmittance performance of
Heat Mirror 88 through the maximum shading performance of Heat Mirror
22.

All
Heat Mirror products can be used with virtually any type of glass -
clear, heat absorbing, reflective, heat-strengthened, tempered,
laminated - to achieve superior performance in a wide range of
aesthetics.

Mirror insulating glass is available with a variety of clear coatings
for mastering the sun's heat. From Heat Mirror 77 to Heat Mirror 22,
solar heat gain is properly controlled, and offers you energy
efficiency with relation to HVAC costs.

Dual Seal vs.
Single Seal
Alpen prides itself in being the only domestic
fabricator currently providing dual seal polyurethane
for fully captured glazing systems as well as dual
seal silicone Heat Mirror units for "butt"
glazed applications. This important and advanced feature has
been requested by all of our customers. We must be apprised
of what seal is required on any job. Your investment in the
quality and integrity of Alpen's dual seal units make for a
dramatically superior alternative to those utilizing a single sealed
approach and enables Alpen to offer an improved warranty to that of any
single sealed Heat Mirror unit. This extremely important fact should be
brought to the attention of the owner, architect or general contractor.
