Prodex Vapor Barrier Insulation

Vapor Barrier Insulation - Basements, Foundations and Metal Buildings


Prodex Total Insulation can help protect your home and building from the damages caused by moisture.

The primary purpose of a vapor barrier is to keep moisture from getting inside your walls. Condensation within the walls can cause wood rot, mold, mildew, and fungus growth. Signs of condensation within the walls include blistering exterior paint and mildew stains on the walls.

Prodex Total Insulation = Vapor Barrier: Class 1. perm<0.1 Eliminates condensation + Reflective Insulation + Radiant Barrier.

A building vapor barrier must be continuous to work - no holes, leaks, un-taped seams or edges. Leakage will negate the effectiveness of the barrier. Any tears, openings, or punctures that may occur during construction must be completely sealed with tape. Ending the vapor barrier at the floor or ceiling junction has the same effect as a large hole. To create the vapor barrier, the seam between the ceiling and wall must be sealed well. Think of your house as a large balloon with the vapor barrier as the skin of the balloon. A leaky barrier is not better than no barrier at all. .

Prodex Total Insulation will keep heat and moisture in during the winter. It will keep heat and moisture out during the summer. It will not absorb moisture in the event of a water leak. If you are finishing your basement, install Prodex Total Insulation (vapor barrier) on the basement walls before framing.

Basements Have Different Insulation Requirements Than The House Above

Recommended Vapor Barrier Insulation for your basement: Prodex Total Fast Action

Due to the underground environment, moisture is the primary consideration in developing  a basement insulation strategy. Excess moisture can cause mold, mildew, odors, decay, fungus growth and wood rot.

A vapor barrier is an essential part of the moisture control strategy for a basement, foundation, home or metal building.

A vapor barrier (moisture barrier) refers to any material that prevents moisture from passing through the walls or roof of a building. This material can be plastic  or better yet, Prodex Total Insulation - 13/64 inch, 5mm closed cell polyethylene foam covered on both sides with .0012-inch (00.03mm) aluminum foil facing. Prodex Total Insulation (Vapor Barrier, Class 1. perm<0.1 ) also provides R-value 16 and a radiant barrier.

Permeability (perms) refers to the measure of the rate of transfer of water vapor through a material. The lower the perm, the fewer the vapor that can pass through. Look for a vapor barrier with a perm of less than 1. Transmission rates are established by standard test methods. One common set of units is g/m²/day. or g/100in²/day. (1.0 US perm = 1.0 grain/square-foot·hour- inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa).

A Vapor Barrier Will Protect Your Foundation

A vapor barrier should be used under a slab-on-grade foundation or poured cement basement floor. Since a damp basement is one of the greatest producers of moisture (up to 50 lbs/day of vapor), the vapor barrier under concrete floor slabs and over earth floored crawlspaces are integral structural components of interior moisture control. A vapor barrier is also needed in your crawlspace to prevent moisture penetration. Recommended vapor barrier insulation for under slab and radiant in floor heat: Prodex Total Under Concrete. Recommended vapor barrier for crawl space ceiling: Prodex Total 48 Inch Insulation

Protect Your Metal Building With A Vapor Barrier Insulation

Condensation can be more significant problem in a metal building than temperature control. Moisture from condensation, rain and ground can create several problems in metal buildings. First, the presence or water or ice in the insulation seriously degrades both the thermal performance and service life of fiberglass, paper, wool and other traditional insulation materials. Second, water in contact with steel contributes to corrosion and lowers the service life of the building. Third, collection of water can lead to dripping, staining, mold, mildew and odors. All of the problems can be solved with properly installed vapor barrier insulation. Even in only moderately humid climates, condensation can cause serious problems in an unprotected metal building. Recommended vapor barrier and metal building insulation: Prodex Total Fast Action.
