A Weather-Resistant Barrier for Homes and Buildings

In today’s world of rising energy costs and changing weather patterns, it’s more important than ever to build energy-efficient homes and buildings that save energy and money while keeping residents, employees and visitors comfortable. Insulation is a vital component of conserving energy. It provides a thermal barrier that helps slow down the transfer of heat into a home or building.

At Cullen Insulation, we provide tailored insulation solutions for residential and commercial buildings throughout the area we serve. Our expert team installs a variety of effective insulation materials. One insulation that we often recommend and install is rigid foam board insulation. It could be the perfect fit for your insulation project.

What is Rigid Foam Board Insulation?

Rigid foam board is a rigid polyisocyanurate or polystyrene insulation product that is formed into insulation sheets. Its lightweight, rigid, Styrofoam-like panels can be easily cut to size for a snug fit in any insulation project. The R-value of rigid foam board insulation is high, at R-6 per inch for polyisocyanurate and R-5 per inch for polystyrene. This gives it better thermal resistance than other types of insulation.

Where to Install Rigid Foam

Rigid foam is most often installed in the exterior walls of residential and commercial buildings, where it acts as a weather-resistant barrier to enhance a building’s resistance to air and moisture. Builders considering above grade vs below grade foam insulation can rest assured. We install both based on a structure’s specifications. It’s appropriate for concrete walls as well as either wood or steel framing.

Benefits of Rigid Foam Insulation

There are a variety of long-term benefits that the installation of rigid foam brings to homes and buildings:

Energy Savings

The thermal barrier rigid foam provides gives HVAC units a break, lowering energy bills.

Prevents Air Leaks

It helps block air flow to increase energy efficiency.

Easy to Handle

Rigid foam is quick and easy to cut to size for the perfect fit every time.

Moisture Control

It offers exceptional moisture resistance that acts as a weather resistant barrier to help with structural integrity. It even retains its R-value after exposure to standing water.

Long-term Durability

It has a long lifespan and needs little maintenance, making it one of the best insulations for cold climates.

Compatibility

Rigid foam works seamlessly with other insulation materials to maximize energy efficiency.

Improves Indoor Air Quality

Its air and thermal barrier properties help keep pollutants and allergens outside for cleaner air inside.

Prevents Corrosion and Decay

Rigid foam insulation resists common acid soils and effectively helps prevent corrosion and decay.
