Is Spray Foam or Fiberglass Insulation More Cost-Effective for DIY Homeowners?

by Wendy Wiegand 01/03/2022

While upgrading a building’s insulation may not feel as exciting as an expansive new kitchen, the potential energy savings add up. Here are a few things about fiberglass and spray foam insulation property owners may want to consider.

What Homeowners Need To Know About Fiberglass Insulation

The upfront investment of fiberglass insulation proves attractive to DIY homeowners because it remains quite low by comparison. In addition, this type of insulation can be purchased at local home materials outlets and easily transported. The rolled “batts” typically present yellow or pinkish fiberglass on one side and a paper layer on the other.

Installation requires DIYers to unfurl them directly into the spaces between the joists above your ceiling. The process makes installing new fiberglass insulation incredibly easy for a DIY homeowner. In terms of being cost-effective, a reasonably fit and agile homeowner may not require the help of a construction professional.

What Homeowners Need To Know About Spray Foam Insulation

The upfront cost of spray foam insulation generally exceeds that of fiberglass batts. This product typically involves equipment to disburse it into attics and behind walls. Other key differences involve where spray foam insulation installations are placed.

Rather than spray the materials between ceiling joists, it makes more sense to install it between roof rafters (support timbers directly holding up the roof). That key difference has significant implications to reduce air penetrations. Unlike fiberglass batts that lay over the ceiling and trap cold air in the attic, spray foam creates a determined barrier against drafts. As a result, the conventional wisdom is that properly installed spray foam can better nearly eliminate air penetrations from entering the building.

How To Decide Between Spray Foam and Fiberglass Insulation

Making an informed decision between spray foam products and fiberglass batts requires DIY homeowners to draw a few simple distinctions. These include upfront costs, reduced air penetrations and the installation process.

Handy DIY homeowners tend to have little difficulty rolling out fiberglass batts. Spray foam, on the other hand, may require enlisting a professional installer and incurring the cost associated with a construction professional. Last, it’s essential to weigh the upfront expenses against how much money each product will save you.
