Testing Envelope Seal

The Alberta Research Council has conducted two sets of tests in order to determine the low temperature flexibility and tensile resilience of Envelope Seal. These tests both indicated that Envelope Seal has excellent elongation and flexibility at extreme sub-freezing temperatures.

Envelope Seal was also tested by EnerVision to determine the extent to which it aids in air tightness. It was found that Envelope Seal can improve air tightness by as much as 43% when compared to other window/door preparations.
