Condensation in post frame buildings can be damaging not only to the building itself, but also to the assets you have stored in them. Blunier Builders controls condensation issues with MoistureLok. MoistureLok is a bacteria resistant, anti-condensation membrane that is factory applied to the underside of the roof steel. This membrane traps the condensation until conditions change and then releases it back in the air as normal humidity. MoistureLok is the superior alternative to conventional vapor barrier methods in appearance, installation, & effectiveness.
