HOW DOES envelopeseal WORK?

EnvelopeSeal adheres to many surfaces,

forming a closed bond wherever it’s applied. Its elastomeric properties allow it to stretch and move naturally with the building. Even in cold weather conditions, EnvelopeSeal has excellent elongation and flexibility at extreme sub-freezing temperatures. The Alberta Research Council has conducted two sets of tests in order to determine the low temperature flexibility and tensile resilience of EnvelopeSeal, both of which confirm its resiliency.

EnvelopeSeal acts as a barrier.

The Canadian Mortgage and Housing Corporation (CMHC) has determined that the window to wall interface is the major contributor to moisture problems in buildings. EnvelopeSeal is an elastomeric co-polymer thermal plastic that acts as a primary barrier to moisture and air penetration at the window to wall interface. Its physical properties allow it to adhere to most surfaces while staying flexible over a wide range of temperatures. These characteristics enable the product to move and adjust with building settling, while maintaining a watertight seal around building openings. Use of EnvelopeSeal is part of the Built Green initiative, and contributes to reducing new home warranty claims while improving air tightness by as much as 43%.

EnvelopeSeal bonds directly

from the flange of the window or door to the substrate of the building whether it be OSB, plywood, or fiberglass board. The excellent adhesion of the product to most surfaces ensures that no moisture or air will penetrate the opening. Furthermore, the product’s elastomeric properties allow it to move and stretch with any building settling making for a permanent seal.
