COMPOSITION
SOF庐SEAL is an extruded, dry, pre-formed foam gasket made of a non-absorbing skin and a soft, highly resilient interior network of open and closed
cells. SOF庐SEAL is clean, free of scale, foreign matter, oil, or water. It has low water vapor permeance making SOF庐SEAL a higher performer than
fiberglass if condensation is formed by moisture laden air leaking through wall cavities and joint openings.
BENEFITS
The Bi-cellular composition of this product outperforms closed cell backer rod, with its ability to resist 鈥渃reep鈥? and compression set. The material is
super resilient and able to conform to irregular contours without leaving voids. This feature provides superior ability to eliminate drafts when used
as an environmental seal.
INSTALLATION (Factory or Field)
Verify that the joint is clean, moisture free and clear of obstructions. Select the SOF庐SEAL in a size that is approximately 25-50% larger than the
joint opening. Fasten SOF庐SEAL uniformly to the joint using roofing nails or staples. Good air leakage control means lower heating bills and a
more comfortable home.
