New Construction Insulation

Build It Right Before The Walls Are Closed

New construction gives you one opportunity to get it right from the beginning.

New construction insulation gives you access to every wall cavity, attic space, rim joist, and other areas that will be much harder to reach after the home construction is finished. Choosing the right insulation for new home construction isn’t just about meeting code. It’s about creating an energy efficient home that stays comfortable year-round while helping reduce unnecessary energy loss.

Insulation Options Matter More Than Most People Realize

Every new home is different. We’ve insulated two houses on the same street that ended up with different insulation systems because the layouts and performance goals weren’t the same.

The floor plan, wall depth, roof design, mechanical systems, and even the way the house faces the sun all influence which insulation materials make the most sense. That’s why we start by looking at the building as a whole instead of recommending the same product for every project.

Colony Insulation works with homeowners, builders, and contractors throughout Southeast Michigan to install insulation for new construction that fits the building, the budget, and the performance goals.

Some of the most common insulation options include:

  • Spray foam insulation
  • Fiberglass insulation and fiberglass batts
  • Fiberglass batt insulation
  • Cellulose insulation
  • Wet applied cellulose
  • Mineral wool for selected applications

New construction home insulated with spray foam in exterior wall cavities to improve energy efficiency and air sealing

Air Sealing Should Come Before Adding Insulation

One thing we see fairly often is a house with plenty of insulation but noticeable drafts because air leaks were never addressed. Air leakage around framing joints, plumbing penetrations, wiring, and framing transitions can account for a significant amount of wasted heating and cooling.

That’s why we focus on the air seal first. It’s a lot easier to seal those gaps now than after drywall covers everything.

Reducing air movement helps keep conditioned air inside the home where it belongs. Proper air sealing also improves energy efficiency, reduces drafts, and helps lower energy bills over time. In many homes, energy losses from air leakage can exceed the heat lost through the insulation itself.

Our Process

We Make Insulation Easy

We keep the process simple: inspect the property, recommend the right insulation system, complete the work with professionalism, and make sure you understand the finished result before the job is done.
Step 1

Evaluate the Property

We look at the space, identify where energy loss or comfort issues are coming from, and assess what type of insulation will perform best in the attic, crawl space, walls, basement, floor, or other key areas.
Step 2

Recommend the Right Solution

Every building is different. We recommend the right mix of spray foam, fiberglass, cellulose, and other insulation products based on the structure, the problem areas, the budget, and the performance goals of the project.
Step 3

Complete the Installation

Our expert team handles the work with the right equipment, careful prep, and quality-focused installation practices. We complete each job with attention to detail so the finished system performs the way it should.
Step 4

Review the Finished Work

Before the project wraps up, we walk you through the completed work, explain the benefits of the insulation upgrade, and make it easy to contact us with any final questions.

Spray Foam Insulation For New Construction

Because spray foam expands as it’s applied, it fills spaces that other insulation materials can’t. In some applications, it expands up to 100 times its original size, making it an excellent choice for difficult-to-reach areas.

Both open cell spray foam and closed cell spray foam have their place. One isn’t automatically better than the other. It depends on what that part of the house needs to do.

Open cell spray foam provides an R-value of roughly R-3.5 to R-4 per inch and works well where sound control and complete cavity coverage are priorities.

Closed cell spray foam offers one of the highest R values available, typically beginning around R-6 per inch. Closed cell foam also creates a durable air barrier while providing added moisture resistance, making it a strong option for rim joists, crawl spaces, and other areas where moisture issues are more likely.

For many projects, cell spray foam provides the best energy efficient insulation when air sealing and insulation need to work together.

Fiberglass And Cellulose Still Have An Important Place

Spray foam isn’t automatically the best insulation for every part of a home.

Fiberglass insulation remains one of the most cost effective choices for many new construction projects. Fiberglass batts fit neatly into open wall cavity framing and are commonly used in exterior walls, interior walls, and attic assemblies.

Blown fiberglass also performs well as attic insulation because it creates consistent coverage across the attic floor.

Cellulose insulation is another practical option. Made largely from recycled materials, it can be installed as loose fill or wet applied cellulose depending on the application. The bonding agent used in wet applied cellulose helps it stay in place within open wall cavities before drywall installation.

Choosing between these insulation options usually comes down to balancing thermal performance, moisture control, budget, and the specific needs of the construction homes being built.

Don’t Forget The Attic And Crawl Space

They’re also two of the easiest areas to get right while the house is still under construction.

Attic insulation helps slow heat loss through the roof while keeping hot air from building up in the attic space during warmer months. The best attic insulation for one project may not be the same for another, but proper coverage combined with good air sealing can make a noticeable difference in comfort and energy savings.

In the crawl space, foam insulation is often the preferred choice because it helps limit moisture, improves the air barrier, and reduces cold floors above. Proper crawl space insulation can also help prevent mildew growth by limiting unwanted moisture movement.

Rim joist insulation is another area that shouldn’t be overlooked. Rim joists frequently allow outside air into the home, making them one of the key areas where spray foam insulation performs especially well.

Building To Code Is Only The Starting Point

Some builders choose to exceed code using the performance method, allowing different insulation systems to work together to achieve better overall energy efficiency. Increasing insulation levels in exterior walls, improving cavity insulation, or selecting higher R value products may provide better long-term performance without dramatically changing the building process.

The goal is to install proper insulation that supports the home’s heating and cooling system instead of making it work harder than necessary.

Choosing The Right Insulation For Your New Home

We’ll look at the wall cavity depth, exterior sheathing, attic design, crawl space, rim joists, moisture exposure, and the overall home construction before recommending a system. Sometimes that means spray foam insulation throughout key areas. Other projects are better served with fiberglass batt insulation, cellulose insulation, or a combination of materials.

Our job is to recommend insulation for new home construction that fits how the building will actually perform for years to come.

Frequently Asked Questions

Questions builders and homeowners often ask before choosing insulation for a new construction project.

What is the best insulation for new construction?
There isn’t one answer for every project. Spray foam insulation often provides the best combination of air sealing and thermal performance, while fiberglass insulation and cellulose insulation remain cost effective options for many new homes. The best choice depends on the walls, attic, crawl space, budget, and overall performance goals.
Mineral wool is not a food source and generally does not attract rodents. However, no insulation material can prevent mice if they already have access to the structure.
Yes. R-38 has a higher insulation value than R-30, but the recommended R-value depends on where the insulation is being installed, local code requirements, and the design of the home.
It varies by climate zone and where the insulation is installed. Attics, exterior walls, crawl spaces, and rim joists can each have different requirements.
