Enhancing Insulation for a Standard Vented Crawl Space in Toms River, NJ

Wednesday, June 5th, 2024 by Michael Gloeckler

Challenge

We are inspecting a typical crawl space in a 55+ community in Toms River, NJ. In these neighborhoods, it's common to find crawl spaces lacking proper insulation and protection for the homes. Without insulation or a liner, moisture can build up, and outside air can infiltrate the crawl space. Additionally, open vents, remnants of outdated construction practices, should be closed and sealed. Unprotected moisture, combined with leaky rim joists and unwanted gases, can infiltrate the crawl space, potentially causing uncomfortable conditions and indoor air quality issues in the living areas above.

Solution

To address this issue, we'll start by spray foaming the exposed rim joists to prevent air leakage. Next, we'll install SilverGlo insulation boards on the inside of the exterior walls to stop unwanted air from entering the crawl space. Then, we'll lay down TerraBlock foam mats to insulate the floor and cover them with a 20 mil thick CleanSpace Liner to prevent gases and moisture from rising. With these measures, we'll establish a solid thermal barrier at the base of your home, blocking unwanted hot or cold air and moisture from entering.

This is the entrance to the crawl space; you'll notice that the cinderblock walls are exposed without any insulation.

Towards the far end of the crawl space, there's an open vent, and the floor consists of dirt.

In this image, we're showcasing the exposed rim joists and porous walls. This is where outside air can seep into the crawl space, leading to cold floors and discomfort in the rooms above.

We're highlighting the exposed floor in the crawl space. The presence of humidity, moisture, and unwanted gases from the dirt floor can lead to indoor air quality issues and discomfort in the rooms above.

This image showcases the installation of CleanSpace liner and TerraBlock insulation on the floors. TerraBlock provides excellent insulation for the floor, while CleanSpace effectively encapsulates the floors, guarding against moisture and reinforcing the thermal barrier between the ground and the house.

This is a comprehensive view of the crawl space, fully insulated and encapsulated.
