Rigid Foam Insulation Installation in Denver
Eco-Friendly, High-Performance Insulation That Fills Every Gap
Rigid foam board is the quiet workhorse of a well-insulated house: thin, high R-value per inch, moisture-tolerant, and ideal where fibreglass fails — concrete basement walls, crawl space walls, rim joists and under siding. PIKA installs XPS, EPS and polyiso board, cut tight and sealed at every seam, so it performs as an air and vapour control layer, not just a thermal one. Every job starts with a free in-home evaluation — we walk the house with thermal-imaging readers, show you where heat is leaving, and give you a written quote. No cost, no obligation.
Signs you need rigid foam insulation
- A finished or soon-to-be-finished basement with bare concrete walls behind the framing.
- Efflorescence, damp spots or a musty smell on foundation walls.
- A crawl space you want encapsulated rather than re-batted.
- A re-side or addition where continuous exterior insulation can be added under the new siding.
- A bonus room over a cold garage ceiling.
Attic Insulation – Your First Line of Defense Against Energy Loss
Your attic is responsible for the majority of your home's heat loss. We install high-performance attic insulation that:
Improves your R-value to meet or exceed Denver climate recommendations
- Prevents warm air from escaping during winter months
- Keeps your home cooler in the summer
- Lowers heating and cooling bills significantly
A properly insulated attic can cut your energy use by up to 20% annually—and we make sure it’s done right the first time.
Where We Install Rigid Foam Insulation
Basement walls
Rigid foam board is glued and sealed to the foundation before framing begins, creating a thermal barrier. It helps prevent cold concrete from affecting comfort and reduces moisture problems in finished basements.
Crawl space walls
Continuous rigid foam board covers the stem walls as part of a complete crawl space encapsulation system. It replaces failed floor batts and helps reduce heat loss while improving moisture control beneath the home.
Rim joists and band joists
Rigid foam board is cut to fit each cavity and sealed around the edges with canned spray foam. This approach reduces drafts and heat loss without the higher cost of full spray foam installation.
Exterior continuous insulation
Rigid foam board is installed beneath new siding during a re-side or home addition to improve the building envelope. It reduces thermal bridging through 2×4 wall studs and helps maintain more consistent indoor temperatures.
Garage ceilings and knee walls
Rigid foam board with a fire-rated covering insulates rooms located above unheated garages. This added barrier helps limit heat loss, reduce cold floors, and improve comfort in the living space above.
Materials and How We Choose
We’re not just installers—we’re local insulation experts focused on quality, comfort, and energy performance. With PIKA Insulation, you get:
XPS (extruded polystyrene)
R-5 per inch, ideal for below-grade foundations and crawl space walls. Its moisture resistance makes it a practical choice for areas exposed to damp soil conditions.
EPS (expanded polystyrene)
R-4 per inch, offering cost-effective insulation for large exterior areas. Its lightweight structure makes it suitable for broad wall surfaces where budget and coverage matter.
Polyiso
R-6 per inch, delivering high thermal resistance for above-grade applications. It works well on exterior sheathing and garage ceilings where space is limited and insulation performance matters.
How a PIKA Job Works
Free In-Home Evaluation
We use thermal-imaging readers to identify heat loss throughout your home. You see exactly where insulation is underperforming instead of relying on guesswork.
Clear, Written Estimate
Receive a written quote during the same visit, with recommended work clearly outlined. We also flag potentially rebate-eligible items to help you plan costs.
Professional Installation Crew
Our own trained crew completes the installation without outside subcontractors. Most projects are finished in one day, depending on the home's size and scope.
Final Walkthrough and Testing
We clean the work area, walk you through the completed installation, and explain the results. When required for rebates, we also arrange post-work testing.
Serving Denver and The Metro
Based in Denver, we serve homeowners throughout the metro area, including Lakewood, Aurora, Littleton, Highlands Ranch, Westminster, Thornton, Parker, and Broomfield, along with the surrounding neighborhoods. Our crew provides the same professional insulation services and free in-home evaluations across our service area, helping homeowners identify heat loss, improve comfort, and reduce wasted energy. Wherever you're located in the metro, you can expect the same straightforward recommendations and reliable installation process.
Frequently Asked Questions
How much does rigid foam insulation cost in the Denver area?
Most basement or crawl space wall projects land between $2.50 and $5.50 per square foot installed, depending on board thickness and how much sealing and fire-rated covering the space needs. You get an exact number after the free evaluation.
Is rigid foam better than spray foam?
They solve different problems. Rigid board wins on flat, open surfaces like foundation walls; spray foam wins in irregular cavities and rim joists with lots of penetrations. We often use both on one job.
Does foam board need to be covered?
Yes — building code requires an ignition barrier (drywall or an approved coating) over exposed foam in living spaces and most crawl spaces. Our quote includes it.
Do you sell foam board?
No — PIKA is an installation contractor. We supply and install the board as part of the job; we don't sell material separately.
