Metal Building Vapor Barrier

Radiant barriers and vapor barriers.

Metal building vapor barrier.

The goal of vapor barrier strategies is to prevent moisture from collecting and corrupting building materials. Metal roofs are notorious for the annoying drips that occur inside the building. Improperly installed a vapor barrier may actually trap moisture inside a wall while a wall that is more porous can breathe effectively and be less susceptible to long term moisture problems. Avoidance of the installation of vapor barriers such as polyethylene vapor barriers foil faced batt insulation and reflective radiant barrier foil insulation on the interior of air conditioned assemblies a practice that has been linked with moldy buildings lstiburek 2002.

This tough and durable fabric barrier lasts and lasts. Like a car warming in the summer sun a building with a metal roof traps heat. Constructed with factory welded double extrusion seams this product provides maximum protection from cold heat condensation and dust. Controlling condensation and moisture infiltration is vital to maintaining the thermal performance of the insulation system within these buildings and homes.

Radiant barriers vapor barriers and your roof. Rhino s vapor barriers rhino steel building systems offers an optional professional insulation system includes a high quality vapor retarder. They are rated by the amount of moisture that can pass through them called perm ratings. A high quality weather resistant barrier wrb is essential to controlling condensation and moisture infiltration in steel sided structures.

Most metal building insulation already comes with a vapor retarder over the fiberglass batt. Metal building insulation vapor barrier alpha manufactures a full range of high quality metal building insulation facings including paper backed and paper free facings that meet industry permeability standards. For example the requirements for a fulfillment center may be different from the requirements of an agricultural application. Rhino s vapor barrier fabric is 300 stronger the metal building facing typically used by other companies.

Two types of barriers are relevant to energy efficiency and moisture control in post frame attics. Metal building construction encompasses a multitude of vapor barrier uses depending on the application. In fact rhino s vapor retarder rates 300 stronger than the vinyl barriers typically offered by most metal building companies. One challenge with post frame structures is that they often come with metal roofs.
