When the right insulation material is used properly, your house can become energy-efficient as well as comfortable. More specifically, you can reduce your cooling and heating cost by up to 20% by adding insulation to your crawl spaces, floors, attics, basement rim joists, and by reducing air leaks throughout your house. If you’re exploring spray foam insulation costs Colorado, you’re in the right place. In general, the cost of spray foam insulation depends on various factors. To understand the dynamics of spray form insulation, including its costs, you should first understand the basics of spray form and the industry lingo. Here’s some more information on this topic.

Spray Foam Basics

Some of the common industry terms and the essentials of spray foam insulation include, among others:

What’s R-Value?

R-value is the gauge of how effectively a material resists heat transmission. A high R-value means greater heat resistance. In other words, a material with a high R-value is a good insulator and vice versa. Take note that R-value works regardless of where the heat is emanating from, the outside or inside, meaning it uses the same principle as a typical vacuum flask. With that in mind, the R-value per inch represents the effectiveness of every inch of thickness of the insulation material.

What Are Board Feet?

Board Feet is essentially square feet with depth or thickness added. One board foot is 1 ft by 1 ft by 1-inch depth/thick. Put differently, a 100-foot kit is one inch thick and it covers 100 square feet. When calculating the cost of a spray foam insulation project, it necessary to use board feet because the work may entail the use of several inch layers to get to the desired R-Value for the insulation project.

Types Of Spray Foam

Here’s an in-depth look at the similarities and differences between the two main variants of spray foam:

Open-Cell Spray Foam Insulation

Open-cell spray foam is a soft and lower-density type of spray foam that uses less material compared to closed-cell foam but this means its insulation ability (R-Value) is lower. Its thickness is about 3 inches after application.

On average the open-cell foam’s R-value is 3.5 to 3.6 for every inch. Therefore, a single application yields a 10 to 11 R-value. It’s an economical choice of insulation for milder climates and it’s perfect for soundproofing, too.

Other pros of open-cell foam include:

  • Enables bi-directional drying
  • The average cost per square foot is lower
  • Can adapt to seasonal movement and long haul creep

Closed-Cell Spray Foam Insulation

This variant of foam is denser compared to open-cell spray foam. Its R-value is 6.5-7 for every inch. With its higher R-value, it gives higher thermal protection. Its thickness is 1 inch after application and you can get a higher R-value after multiple applications. This makes it ideal for small areas that require a high R-value to fulfill the building code requirements. Other pros of closed-cell spray foam include:

  • Can resist mass water
  • Can be applied even in extremely low temperatures (5°F at least)
  • Includes impact resistance as well as wall racking strength
  • Lower vapor permeance
  • Higher bond and tensile quality

How To Estimate Spray Foam Insulation Cost

To estimate the cost of a spray foam insulation project, you need these two numbers, the surface area you want to cover as well as the R-value you want to attain.

Size Of Insulation Space

One of the main reasons why you should hire an expert for your insulation projects is that they can conduct a thorough assessment of the areas that you want to insulate. A home energy audit conducted by a professional identifies the particular spots where energy is being lost. Once you’re clear on the surface areas that need to be covered and the ideal R-value, you can then calculate the cost based on the surface area and the R-value offered by the type of spray foam you opt to use. A professional contractor can help you choose the type of spray foam that’s ideal for your home.

Is Spray Foam Safe?

Once the spray foam is cured and inert, it’s safe. However, uncured spray foam is a health hazard, and therefore, only a certified insulation contractor should handle it.
