Crawlspace Insulation In Bergen NJ

Crawlspace Insulation Contractor In Bergen County, NJ

How you insulate a crawlspace depends on whether it’s ventilated or unvented. Most building codes require vents to aid in removing moisture from the crawlspace. However, many building professionals now recognize that building an unvented crawlspace (or closing vents after the crawlspace dries out following construction) is the best option in homes using proper moisture control and exterior drainage techniques.

 

If you have or will have an unvented crawlspace in Bergen County, NJ, the best approach is to seal and insulate the foundation walls with close cell spray foam rather than the floor between the crawlspace and the house. This strategy has the advantage of keeping piping and duct-work within the conditioned volume of the house so these building components don’t require insulation for energy efficiency or protection against freezing.

The recommended strategy is to reduce air leakage as much as possible and to provide controlled ventilation as needed. Before air sealing, you should first:

• Detect air leaks
• Assess your ventilation needs for indoor air quality
•     You can then apply air sealing techniques and materials, includingspray foam, rigid foam board, caulking and weather-strips

Consider a home energy audit in Bergen County, NJ, to identify all the ways your home wastes energy and money.

Note that air sealing alone doesn’t eliminate the need for proper insulation to reduce heat flow through the building envelope.
