What is Spray Foam Insulation?

Spray foam insulation is a versatile and effective solution used to insulate walls, roofs, lofts, and crawl spaces. It expands on contact to fill gaps, cracks, and hard-to-reach spaces, creating a seamless insulation layer. Available in both open-cell and closed-cell formulas, spray foam not only helps regulate indoor temperatures but also acts as an air and vapour barrier.

Variety of Spray Foams 

HandiFoam, known for its innovative and quality products, presents a variety of spray foams that cater to different needs.

Adhesive Foams: Products like HandiFoam Pro Adhesive GF are crafted to provide a strong bond, ideal for adhering surfaces and components in roofing structures.

Window and Door Foams: Tailored for sealing gaps around windows and doors efficiently, ensuring no air leakage and providing excellent insulation, e.g., HandiFoam Window & Door Gun Foam Sealant.

Straw Foams: Available in various formulas such as HandiFoam Black Straw Foam, these are ideal for quick patchwork and sealing small gaps with precision.

Key Benefits of Spray Foam

  • Superior Energy Efficiency: Reduce your energy bills with spray foam's high insulation value and complete air sealing.
  • Improved Indoor Comfort: Enjoy stable indoor temperatures and fewer draughts year-round.
  • Moisture & Mould Resistance: Closed-cell formulas help resist water ingress, reducing the risk of mould and mildew.
  • Structural Reinforcement: Closed-cell spray foam can add strength to your walls and roof assemblies.
  • Noise Reduction: Open-cell foams offer excellent sound dampening between floors and walls.

Practical Applications of Spray Foam Insulation

Spray foam is ideal for both residential and commercial projects. Common use cases of insulating spray include:

  • Insulating roof decks and attic spaces
  • Sealing crawl spaces and rim joists
  • Creating air barriers around HVAC and ductwork
  • Filling gaps in new construction or renovation projects

Spray Foam Insulation Selection Guide

Choosing the right spray foam insulation depends on your project needs, application area, and performance goals. Here's a quick guide to help you make the best choice:

1. Decide Between Open-Cell vs. Closed-Cell

  • Open-Cell Spray Foam: Lightweight, flexible, and breathable. Ideal for interior walls, ceilings, and soundproofing. Offers a lower R-value but excellent acoustic performance.
  • Closed-Cell Spray Foam: Dense and rigid with a higher R-value. Best for exterior walls, roofs, basements, and areas exposed to moisture. Adds structural integrity and vapour resistance.

2. Evaluate R-Value Requirements

Higher R-values mean better thermal performance:

  • Open-Cell: ~R-3.5 per inch
  • Closed-Cell: ~R-6.5 per inch
    Match your insulation needs to local building codes or energy efficiency goals.

3. Consider Application Size

  • For small repairs or touch-ups, opt for Handi-Foam Quick Cure or low-volume kits.
  • For large-scale projects, choose Touch 'n Seal 600 kits or similar high-yield systems to reduce refills and maintain coverage consistency.

4. Assess Moisture Conditions

If you’re insulating areas like basements, crawl spaces, or roof decks where moisture can be an issue, always choose a closed-cell foam for its superior water resistance and vapour barrier properties.

5. Don’t Forget Accessories

To ensure smooth application and maintenance:

  • Use spray foam applicator guns for precise control.
  • Keep a foam cleaner on hand to prevent clogging and maintain equipment.

Spray Foam vs. Traditional Foam Insulation

When comparing spray foam insulation to traditional foam board insulation, the key differences lie in application, performance, and efficiency. Spray foam is applied as a liquid that expands to fill every gap and crack, creating an airtight seal and delivering superior thermal performance, especially in hard-to-reach or irregular spaces. Closed-cell spray foam also acts as a moisture barrier, making it ideal for basements, crawl spaces, and roof decks. In contrast, traditional foam boards (such as EPS, XPS, or polyiso) are rigid sheets that require manual cutting and sealing around edges, which can leave gaps if not installed precisely. While foam boards are more budget-friendly and suitable for DIY projects on flat surfaces, they typically lack the comprehensive air sealing and higher R-values that spray foam provides. If you’re looking for maximum energy efficiency and long-term savings, spray foam is the more advanced and effective solution.
