Crawl Space & Basement Insulation in Raleigh

Stop Throwing Money Out the Window!

crawl space insulation


It's no secret that a well-insulated house operates much more efficiently than one that is not insulated properly. It also can greatly reduce the size of the HVAC equipment that you need to reach peak results.

The real secret lies in the understanding of our building codes and realizing these codes are minimum standards. For maximum efficiency and control of your home, the standard must be raised to meet modern, energy-efficient standards.

Retrofit vs. New Construction

Crawl Space & Basement Technologies works with existing homes. We do not work in the new construction arena. This has given us a very specialized knowledge of energy efficiency in an existing home, especially older construction. In new construction, it is easy to design a modern home with maximum insulation to gain the ultimate energy efficiency. However, an existing home must be retrofitted to receive its own realistic energy efficiency target. It usually is not feasible to remove all the sheetrock, ceilings, etc..  So, a retrofitted house or existing house can benefit by having attic insulation and crawl space insulation added to the home.

Raleigh Crawl Space and Attic Insulation

Crawl Space Insulation in Raleigh

Crawl Space Insulation can range anywhere from a simple R-19 replacement to a full crawl space encapsulation where we use closed-cell spray foam or foam board on the wall of the crawl space to achieve maximum efficiency. There are other choices and combinations as well to seal the crawl space in your Raleigh home. Our team will inspect and report our findings to help you determine what the best option is for you.

Raleigh Attic Insulation is very similar to crawl space insulation in that both areas have virtually been ignored in building sciences in recent years. The attic is the second reason air is pulled from the crawl space inside the home. It is the second part of the "Stack Effect" or "Chimney Effect." An attic can reach temperatures as high as 165 degrees in our hot, humid climate. This extreme heat causes great energy loss and inefficiency. The EPA reports that the average home loses over 40% of its heated or cooled air through a ventilated attic!

Get Control Over Your Rising Energy Costs and Choose Spray Foam Insulation for Your Raleigh Home!

You can't beat the benefits of Spray Foam Insulation! It seals your home from air and moisture, reduces your utility bills, strengthens your home, and protects your family's health from dangerous mold, pollutants, and allergens.

How Does Spray Foam Insulation Work?

A two-part mixture is applied by trained applicators to the inside surface of the walls, to the underside of the roof, and to the walls in basements and crawl spaces. The spray mixture expands rapidly to fill all cracks and voids completely, and permanently adhering to wood, masonry, metal studs, and joists.

Why Choose Spray Foam Over Other Types of Insulation?

First, its high R-Value per inch provides outstanding thermal performance, so it minimizes hot and cold spots that can affect the efficiency and comfort of a building. Second, its rigidity provides added structural integrity to your basement and attic walls. Third, it acts, as a secondary moisture vapor barrier to help reduce the risk of moisture intrusion in the wall cavity.

When it comes to insulation, no competing product can compare to the features of spray foam. Take a look at the insulation rating chart to see how conventional insulation measures up to foam.
