Rigid

Solid foam boards that deliver strong insulation and moisture resistance for walls, roofs, and foundations.

What is rigid insulation?

Rigid insulation — also known as foam board insulation — is a durable, high-performance material made from solid foam panels. Common types include expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate (Polyiso). These boards are designed to provide superior thermal resistance (high R-value per inch) and moisture protection, making them ideal for walls, roofs, foundations, and basements. Rigid insulation is a popular choice for both residential and commercial applications thanks to its strength, energy efficiency, and versatility.

Why choose rigid insulation?

Rigid insulation stands out for its exceptional durability, moisture resistance, and insulating power. While batt and blown-in insulation work well inside walls and attics, rigid foam boards deliver unmatched performance in areas exposed to moisture or extreme temperatures. Here’s why homeowners and builders often choose rigid insulation:

Higher R-value per inch

Provides more insulation power with less thickness.

Excellent moisture resistance

Perfect for basements, crawl spaces, and exterior walls.

Long-lasting performance

Doesn’t sag, settle, or degrade over time.

Versatile applications

Can be used under siding, concrete slabs, or roofing systems.

If you want insulation that’s built to last and offers maximum energy efficiency, rigid foam boards are an excellent investment.

Benefits of using rigid insulation

High R-value for outstanding energy efficiency.

Moisture Resistance

Ideal for below-grade or high-humidity areas.

Durable & Long-Lasting

Maintains performance for decades without sagging or settling.

Structural Support

Adds stability and strength to walls, roofs, and foundations.

Versatile Use

Works for interior, exterior, and under-slab applications.

Energy Savings

Helps reduce heating and cooling costs by maintaining consistent indoor temperatures.

What are the different types of rigid insulation?
Addition sign

Rigid insulation typically comes in three main types: EPS (Expanded Polystyrene): Cost-effective and moisture resistant. XPS (Extruded Polystyrene): Strong, durable, and excellent for below-grade use. Polyiso (Polyisocyanurate): Offers the highest R-value per inch and is ideal for roofs and walls

Where is rigid insulation used in a home?
Addition sign

Rigid insulation can be used in many areas, including exterior walls, foundations, crawl spaces, attics, roofs, and under concrete slabs. Its strength and moisture resistance make it suitable for both interior and exterior applications.

Is rigid insulation environmentally friendly?
Addition sign

Many modern rigid foam boards are made with eco-conscious materials and blowing agents that reduce environmental impact. They also improve your home’s energy efficiency, lowering your carbon footprint over time.

Can rigid insulation be combined with other types of insulation?
Addition sign

Yes — rigid insulation is often used alongside other materials like spray foam or batt insulation for optimal energy efficiency. For example, foam boards can be installed on exterior walls while fiberglass batts insulate the interior cavities.
