New Home/Construction Insulation
Trust in Foam Co.’s exceptional home insulation services as you embark on your new investment journey in St. Louis, MO, and its surrounding areas. Insulating during the construction phase not only saves on costs but also provides long-term benefits, including critter deterrence and safeguarding against structural moisture damage.
Whether it’s your attic, walls, garage, or basement, our collaborative approach with builders ensures custom insulation plans that meet the unique needs of each project.
Why Insulate During Construction?
Installing insulation before drywall and finishing offers several long-term benefits:
- Improved energy efficiency and HVAC performance, as proper insulation reduces the need for heating, keeps warm air inside during winter, and blocks hot air in summer.
- Enhanced indoor air quality and comfort by maintaining a consistent temperature inside the home year-round.
- Protection from moisture, pests, and structural damage.
- Compliance with local building and energy codes.
- Lower utility bills and higher resale value by reducing energy bills and heating and cooling costs.
Foam Co. works closely with homeowners and builders to deliver efficient, code-compliant insulation systems tailored to each project. Proper insulation helps maintain year-round comfort and reduces energy bills.
Insulation Products We Offer for New Construction Projects
Foam Co. provides four types of insulation that can be applied throughout your build. Many contractors recommend specific insulation materials—such as spray foam, cellulose, fiberglass, or mineral wool—for different parts of the home to ensure optimal performance. We’ll help you add insulation and select the right materials for effective insulation of your new property, based on the layout, budget, and performance goals.
Spray Foam Insulation
Spray foam is ideal for new builds that require airtight sealing and high energy performance. We offer both open-cell and closed-cell spray foam options for walls, attics, basements, and crawl spaces.
- Expands to seal gaps and prevent air leakage, creating an effective air barrier and air seal
- Excellent thermal resistance and moisture control
- Supports services like attic insulation, rim joist sealing, and vaulted ceilings
Blow-In Insulation
Loose-fill cellulose insulation, made from recycled paper products and treated with fire retardants, is blown into walls and attic floors, filling voids and irregular spaces. This product is especially effective in open attic areas or where full coverage is needed.
- Adapts to complex spaces and layouts, effectively reducing air leaks
- Excellent thermal coverage for attics and ceiling voids
- Used for attic insulation, roof decks, and dense wall cavities
Batt and Roll Insulation
Batt insulation uses pre-cut fiberglass sheets (commonly referred to as fiberglass insulation, the traditional material for batts) and is commonly used in new wall cavities, ceilings, and floors. It’s a cost-effective option that offers both soundproofing and thermal benefits.
- Budget-friendly and fast to install
- Ideal for dry areas and interior sound control
- Often used in garage insulation, interior walls, and unfinished spaces
Mineral Wool Insulation
Mineral wool provides exceptional fire resistance, soundproofing, and moisture protection. Made from stone fibers, it’s a great choice for safety-critical or damp areas.
- Non-combustible and mold-resistant
- Helps meet fire-rated wall assembly codes
- Commonly installed in basements, garages, and floor assemblies

FAQs about attic & wall insulation
What type of insulation is best for new construction?
Spray foam is often preferred for its air sealing and moisture resistance, but batt, blow-in, and mineral wool are also excellent choices depending on the area and budget.
Can I combine insulation types?
Yes. It’s common and effective to use a mix of insulation types, like spray foam in key areas and fiberglass batts elsewhere.
When should insulation be installed during the build?
After plumbing, HVAC, and electrical rough-ins, and before drywall installation.
Do your products help meet code and HERS ratings?
Absolutely. We install insulation that supports HERS-rated construction and helps meet Missouri’s energy efficiency requirements.
Are there any incentives or rebates for installing insulation?
Yes, installing insulation might qualify you for government incentives, tax credits, or utility rebates. You could receive up to 30% of the cost back, up to $1,200, but this doesn’t cover installation costs. Eligible products include typical bulk insulation and products that reduce air leaks, given they have a Manufacturer’s Certification Statement. This can make insulation one of the most cost-effective home improvements.
