Spray Foam Insulation

Overview

Closed cell spray foam insulation is an inert semi-rigid foam that expands as it forms, creating countless air pockets in the process. Most insulation experts consider it to be the best performing insulation that’s commonly available.

Specialized spray foam insulation companies and spray foam installers simultaneously mix and spray two liquids that, when combined at a specific temperature and pressure, expand and solidify with countless tiny air pockets inside.

This process is somewhat like molding foam insulation boards to the location in seconds. The air pockets (or “cells”) are isolated or closed off from each other, which is what makes it closed cell spray foam.

Because there are so many individually separated air pockets, the material acts as an incredibly effective insulator.

More on Spray Foam Insulation

Manufacturers create different versions of the product, but most spray foam R Values are between 6 – 7.5 per inch. Because R Value doesn’t consider air sealing and fluctuating temperatures, effectively all spray foams outperform traditional insulation with an equal R Value. 

Not all foams are created equal, which is why good spray foam insulation contractors stay updated with the latest foam advancements.

Spray foam installers utilize a similar technique to spray painting, though the 3 dimensional nature of the foam requires highly specialized techniques and equipment.

Spray Foam Explained

What is Spray Foam?

Spray foam insulation is a polyurethane based compound that spray foam insulation companies apply to form insulation and an air seal barrier on walls, roofs, and other surfaces. Insulation contractors consider this to be the top-of-the-line category of insulation.

Open vs Closed Cell Foam

Overview

Closed cell spray foam insulation is an inert semi-rigid foam that expands as it forms, creating countless air pockets in the process. Most insulation experts consider it to be the best performing insulation that’s commonly available.

More on Open vs Closed Cell Foam Insulation

Two prominent types of spray insulation exist: open cell spray foam and closed cell spray foam. Open cell foam has connected air pockets, so it provides less R-Value, isn’t an air barrier, and is much softer. 

Closed cell foam fully seals around the air cells, making it much stronger and better at insulating (see R-Value). Closed-cell foam has grown in the insulation market, while open-cell foam has become increasingly rare.

Benefits of Spray Foam Insulation

Insulation Density

Higher R-Value

The single most important differentiator between this and other insulation types is spray foam r values are much higher, often more than double, r values of fiberglass and cellulose.

If there is unlimited room in walls or attics for insulation, this wouldn’t be a consideration. But outside of flat attics, for example in walls and sloped ceilings, there’s usually only a few inches of space for insulation.

Lower Bills

More Efficiency

Reduce your energy bills for as long as you own your home or business. An insulation upgrade will generally pay for itself in just a few years through reduced energy costs alone while extending the life of other building systems like the roof. 

Compared with conventional insulation, the savings in heating and cooling can be considerable, up to a 40 percent total reduction.

A Safer Home

Stop Issues Before They Start

The many safety benefits of foam work together to make homes and buildings far safer for the occupants. There are fewer rodents and pests, less chance of lumber rot, and a lower chance of mold development. It even can help the building resist damage from extreme weather.

Foam insulation only takes a few hours to set. After this and the air cycles, spray foam insulation is as safe as any plastic or styrofoam in a home. 

Reduce Mold

Health & Safety First

Mold requires 4 things to grow: air, moisture, warmth, and food. The use of polyurethane as insulation eliminates condensation on surfaces to reduce or fully eliminate moisture accumulation. This kills existing mold and prevents future growth by indefinitely cutting off a lifeline.

Closed-cell foam is so good in high-moisture areas that it’s approved by FEMA for use in flood regions.

Lasting Application

A Permanent Solution

Good spray foam insulation contractors will conform foam to the specific requirement of your building. It doesn’t sag or collapse over time, and doesn’t have seams for air and heat to slip through. 

Spray foam is a permanent and custom-fit solution every time.

Reduce Pests

Extra Rodent Control

The best spray foam insulation contractors use equipment that allows for highly expanding foam. This means tiny passageways that mice and pests use for access into the building get blocked off.

Rodents rarely manage to burrow through closed cell foam, making this a lasting solution to rodent and pest issues.

Automatic

State Rebates & Incentives

Many (though not all) insulation projects are eligible for hundreds of dollars in rebates through the Wisconsin Department of Energy. We typically capture at least 1 rebate per week for our clients.

We are certified to implement these rebates and complete nearly all the paperwork for you. We even instantly discount the rebate from your invoice, so you’re not left waiting for the rebate check to arrive.

Know YOUR Numbers

Planning with general numbers often leads to inaccurate estimations and budgets. That’s one of the many reasons we offer free estimates. Whether you need a quick fix or are planning for work next year, work with numbers specific to your home.
