Why Choose Closed Cell Spray Foam?

Peritus closed cell spray foam insulation makes complete sense from the moment it bonds to a home or any building.

You can actually see the seal created as foam thoroughly fills every crevice to provide a seamless high performance barrier, specially formulated to protect the building, the occupants, and your investment. Consider the benefits: higher R-values, increased energy savings, low long-term maintenance costs, effective sound insulation, added structural strength, resistance to mold, pests and pollutants, and even reduced installation and construction waste. Start smart with Peritus spray foam insulation and stay strong with energy savings of up to 40% over other insulation techniques.

Closed-cell foams resist water penetration and moisture build-up. Moisture can eventually attract bacterial growth, promoting mold, which can eat away at wood and compromise structural integrity. Closed-cell foams can be exposed to water without absorbing it, making it particularly useful against a subgrade foundation, for example. It does not expand in volume as much as open-cell foams do.

Closed-cell foam uses the same suspended bubbles in a polyurethane matrix as the open form but the bubbles are filled with a blowing agent. The blowing agent provides a more effective thermal barrier than air, leading to higher R-values compared to other insulations. Closed-cell foam insulation is denser than open-cell foam, which breathes; closed-cell foam is essentially incompressible once cured. It is the more common of the two types of polyurethane spray foams. In the trades, it is known as “medium-density” or “two-pound” foam. Closed-cell polyurethane foams have R-values around 6.0-7.14/in.

The Benefits of Closed Cell Spray Foam

  • 1. All in one product

    Closed cell spray foam insulation performs as an all-in-one product – insulation, air barrier, vapor retarder and, many are classified as a water resistive barrier (WRB). This combination means that there is an opportunity to reduce additional costs (and therefore, also labor costs) as well as time during the construction phase. Closed cell, medium density spray foam insulation can insulate to an R-value up to 7.1 per inch, can reduce air leakage, minimize water and moisture transfer and also, optimize energy efficiency.

  • 2. Smooth and even application

    Closed cell spray foam insulation can deliver a tight air seal around conventional brick tie penetrations. The conventionally used XPS rigid foam board requires mechanical fastening which adds labor to the project. Plus, mechanical fastening can compromise the continuity and integrity of the insulation. Closed cell spray foam insulation, like Icynene ProSeal, on the other hand is sprayed to adhere to the wall, completely sealing around all connectors and attachments. Greater flexibility in attachment placement is also possible.

  • 3. Less is more

    By eliminating the requirement of additional materials as well as the labor associated with it, there is an opportunity for architects and builders to use a high performance material that outperforms alternatives such as XPS rigid foam board, more cost effectively. Spray foam insulation to be installed with fewer steps and at a lesser cost than assemblies using rigid foam insulation.

  • 4. Easily applied to curves and unique angles

    As a liquid that is sprayed onto the exterior surface, closed cell spray foam in a continuous insulation application allows architects to maintain their unique design elements without compromise. The curves of a building that uses XPS rigid foam board would likely lead to a very labor intensive process since the foam boards need to be cut to shape and then taped at each joint. An installation of closed cell spray foam insulation would be quick, smooth and far less labor intensive as it insulates and air seals in one step while also providing a water resistant barrier.

Are you tired of your cold basement smelling like a cold basement? Encapsulate it with “Closed Cell” Spray Polyurethane Foam insulation and get rid of the damp, moldy, musty smells. Closed cell spray polyurethane insulation is waterproof, meaning no ground water that normally seeps through the wall will penetrate through the closed cell structure of the sprayfoam. Closed cell insulation is ideal for a basement because you never have to worry about mold growth behind your drywall like with Fiberglass insulation. It will help keep your energy bills down while helping to keep your basement war,  healthy and mold free.
