Emseal Log Home Gasket Tape
Emseal offers 2 Types of Log Home Gasket Tapes:
CLASSIC: For more than 30 years EMSEAL has offered an economical, expanding, open-cell, foam tape impregnated with water-based, acrylic-modified asphalt. Classic Log Home Gasket Tape provides UV stability and sealing ability, as well as resistance to aging and to vermin (bugs, rodents, birds, etc.).
ACRYLIC: EMSEAL Acrylic Log Home Gasket Tape was developed in the early 1980’s using in place of asphalt, a water-based, acrylic impregnation. Compatible with liquid sealants, chinking, and stains and preservatives, it is clean-handling and free from visible contact staining.
EMSEAL Acrylic Log Home Gasket Tape is particularly suitable for construction methods such as Swedish cope and is widely used by handcrafters. It is also suitable for flat-on-flat construction where sealant tape is installed at the outer edges of the logs AND where sprayed-on log sealer or stain may come in contact with the tape.
