Proper ventilation and the installation of a moisture barrier are important to preserving the wood foundation and subflooring of your home. Wood damage in homes due to wood-destroying insects is a serious problem and causes approximately $1 billion in damage annually. Cook's offers two effective ways to reduce the risk of damage.

1. Temp-Vents
Temp-Vents are the premier automatic foundation vents used as a defense against excess moisture in crawlspace homes and buildings. Once installed by a Cook's professional, Temp-Vents open and close automatically depending on air temperature, allowing the proper amount of air to circulate under the structure. No electricity is needed.

Additional Temp-Vent features include:

• Help save heating costs in winter
• Dual screens on both sides of vent prevent pest entry into the crawlspace
• Enhance the value and beauty of your home
• Help prevent frozen water and sewer pipes
• Peace of mind knowing that your vents are opened or closed during the appropriate season
• Convenient - Automatic action avoids manual opening and closing of vents outside

2. Moisture Barriers
The installation of a moisture barrier and proper foundation ventilation are important to preserving the wood foundation and subflooring of your home.

The installation of a Cook's moisture barrier in the crawlspace will cause soil moisture to condense on the underside of the barrier and return to the soil. This reduces condensation on floor joists, subflooring and other structural timbers that lead to attack by wood-destroying insects.

A Cook's moisture barrier is professionally installed in 70 to 80% of the crawlspace, allowing wood to dry slowly, minimizing warping and cracking. Each barrier is made of 6-mil polyethylene and is non-transparent, a combination proven to provide protection over the years and reduce barrier deterioration.
