Choosing the Right Insulation for Your Next Job
Posted: December 1, 2025 | By: PPM Supply
Insulation shouldn't be an afterthought in the planning process for any renovation or building process - it sets the stage for long-lasting comfort. Any contractor who's had to update insulation knows the importance of choosing the right materials from the start. Helping your clients make informed decisions from the start can help them avoid costly upgrades down the line. In this blog, we break down five types of insulation, their practical applications, essential accessories, and three key factors every contractor should keep in mind for a successful insulation job.
Choose The Right Insulation For Your Project
Whether you're insulating a new project or upgrading an existing one, picking the right insulation starts with understanding your options.
-
Stone (mineral) wool insulation:
Made from natural stone and minerals, this insulation is the premier choice for protection and comfort. Mineral wool offers superior fire and moisture resistance, R-value, and soundproofing compared to its fibreglass competition. As the industry leaders in stone and mineral wool insulation, ROCKWOOL products are our recommended product for mineral wool insulation.
-
Fibreglass insulation:
As a cost-effective, easy-to-install option that provides reliable thermal performance for walls, attics, and ceilings, there's no question why fibreglass insulation is a versatile job-site staple. Consider Owens Corning “Pink” insulation for large-scale projects or budget-friendly options, available in a range of sizes and R-values.
-
Styrofoam (rigid foam) insulation:
When keeping moisture out and adding strength to foundations and exterior walls is a priority, consider styrofoam insulation. A few good styrofoam insulation options include DuPont XPS, Type II Expanded Polystyrene and Isolofoam. The product really depends on the project and budget.
-
Spray foam insulation:
Spray foam insulation expands to seal gaps like no other material can. It may be an excellent option for clients looking for superior air and moisture control in tight spaces or high-performance builds.
-
Key Factors To Consider For Your Next Insulation Job
R-value, moisture resistance and energy efficiency are the three pillars of an insulation job done right. Here's what you need to know:
-
R-value:
The higher the number, the better the insulation keeps heat in or out.
-
Moisture resistance:
Keeps materials dry, preserving the structural integrity and long-term thermal performance.
-
Energy efficiency:
Good insulation saves energy, lowers bills and keeps your clients happy long after you've wrapped the job.
