Insulation

When foundation vents were installed in crawlspaces they allowed cold air to enter. In the winter months the cold air had the potential of freezing water pipes and allowing the floors to remain cold. This challenged the heating system to try to warm the home. Fiberglass insulation had to be added to the floor joists in an attempt to prevent the cold crawl space air from making the floors cold. The same foundation vents that allow the cold air to enter in the winter also allowed humid air to enter in the summer.

The humidity would condense in the cool crawl space and collect on the fiberglass insulation. Between the humidity and occasionally rodents, the fiberglass insulation often would fall to the ground. Styrofoam insulation is also often used to insulate the exterior crawl space walls. This is a preferred method. If foundation vents are installed the insulation value will be decreased by the foundation vent openings allowing cold air to bypass the insulation.

Creating a "Conditioned Crawlspace" utilizing Styrofoam insulation and eliminating foundation vents is the preferred method for energy efficiency and humidity control. Crawlspace Doctor has developed systems for all crawl space insulation needs.

 

Testimonials

This is a brief note of appreciation for your work on our crawlspace. Your work was excellent; we are very pleased with the results. We do not get any moisture inside the house and the crawl space itself is dry. The pump you installed there has done a wonderful job during the recent heavy rains, which caused problems for many people. It is great to have peace of mind, knowing that the crawl space is protected. We are also happy with your prompt response to any questions and special requests that we had. Keep up the good work. We can recommend your work to anyone without any reservations
