ExoAir® Eco is a UV-stable, pre-compressed, self-expanding, flexible joint seal. It is a polyurethane foam that is impregnated with a modified acrylic resin and treated with a pressure-sensitive adhesive on one side for ease of installation. ExoAir Eco self-expands to fill the joint creating an elastic, vapor permeable, weather tight seal.
Tremco compressed tapes are compatible with and can be sealed with silicone, urethane and acrylic sealants. If the tape is sealed, however, the vapor-permeability is reduced due to the moisture vapor transmission value of the sealant. Tremco compressed tapes are UV- and weather-resistant and require no additional seal.
