Crawl Space Insulation & Radiant Heat Barrier 

Fiberglass dripping off of the ceilings of a Port Alberni crawl space

Fiberglass insulation in a crawl space tends to soak up moisture and humidity, goring mold and eventually causing it to "drip" off the ceiling. And even when it's where it belongs, wet fiberglass is a poor insulator.

Crawl spaces narrow structures installed directly into the dirt under your home. As such, they tend to soak up the natural cold of the earth around your home and transfer it into the air in your crawl space.

If you have utilities in your crawl space such as your water heater, furnace, hot water pipes, or furnaces, your energy bills will suffer. This cold will bombard your utilities, forcing them to work harder just to maintain status quo.

At Island Basement Systems, we can upgrade your crawl space's energy efficiency with products that are durable, long-lasting, and made especially for a the crawl space environment.

Crawl Space Insulation

TerraBlock is a unique, durable crawl space insulation and liner in one. It's the first insulation product created specifically for rough, uneven crawl space floors, which can be as cold as 55 °F.

Made for floors and walls alike, this provides a puncture-resistant, padded solution for your crawl space.

If you've already decided to repair your crawl space and install a liner, this is the product for you.

TerraBlock provides energy-savings and moisture protection at the same time!

TerraBlock Specifications

  • Padded, Insulated Design -- TerraBlock is made of ¾" of foam insulation. It's padded, puncture-resistant, and durable enough for access by servicemen and homeowners.
  • Installs On Walls & Floors-- TerraBlock is appropriate for crawlspace walls and floors. However, intricate details will need to be wrapped with our CleanSpace Vapor Barrier.
  • Compatible With Our CleanSpace System -- TerraBlock can be used as a standalone product, or it can be combined with our drainage matting, radiant heat barrier, or other products.

Crawl Space Radiant Barrier

Another great way to make your crawl space more energy efficient is to install a radiant heat barrier on the walls and floors. For this, we recommend our HeatBlock system.

Like TerraBlock, this radiant heat barrier also serves as a vapor barrier in your crawl space -- holding back moisture while keeping heat in your home. For the best in energy efficiency, combine HeatBlock and TerraBlock together to keep the cold out -- and the heat in!

HeatBlock Specifications

  • Anti-Mold Additive -- HeatBlock is installed with our UltraFresh antimicrobial additive, so it won't support growth of mold or mildew.
  • Tough, Durable Design -- As a 10-mil cord-reinforced liner, HeatBlock is strong enough to hold up to normal wear and tear as servicemen and homeowners crawl or walk on top of it.
  • Installs On Walls & Floors With Our System-- Install HeatBlock on your walls, floors, or both. Our radiant heat barrier combines well with TerraBlock, our drainage matting, or any of our other crawl space products.
