Foam Spray Insulation

Foam Spray Insulation: What You Need to Know

Foam spray insulation, also known as expanding foam or polyurethane sealant, is used to seal gaps, block air, and improve energy efficiency in residential and commercial settings. Products are available in Standard or Pro formats, with insulation rated by R-value—the higher the R, the greater the resistance to heat flow. Some foams also reference R per inch, which measures thermal resistance based on thickness for easier product comparison.

Type:

• Standard: Designed for everyday residential or light commercial use, these formulas offer reliable insulation and sealing for common gaps and joints. Most come with built-in nozzles for simple application, making them ideal for homeowners or contractors doing smaller jobs.
• Pro: These high-performance cans are engineered for professional applicators, requiring a dispensing gun for controlled, continuous flow. Pro foams deliver greater precision and volume coverage, perfect for large-scale or repeated use.

Application:

• Fireblock: Formulated to resist flame spread through concealed spaces, such as wall cavities or floor gaps. Meets fire safety codes and adds an extra layer of protection in sensitive areas.
• Foam System: Heavy-duty insulation foam designed for large coverage, typically packaged in a 5-gallon kit. Ideal for construction professionals working on full-room or high-volume projects.
• Gap Filler: Targeted solution for sealing larger voids that standard foams may not handle effectively. Expands deeply into irregular gaps, helping to stabilize and insulate troublesome spaces.
• Gaps and Cracks: The most versatile option for sealing around plumbing, HVAC, wiring, and trim. Expands moderately to fill gaps without creating excess pressure.
• Pestblock: Specialized foam that helps block entry points for insects and rodents. Contains additives that deter nesting and intrusion without being harmful indoors.
• Windows and Doors: Designed to provide airtight seals without overexpanding, preventing frame warping and ensuring smooth operation of doors and windows. Ideal for energy efficiency upgrades and retrofit projects.

Size & Volume:

• 12 oz. (5–12 sq. ft): These cans are the most common and are designed for household projects such as sealing window frames, door jambs, and small cracks. They’re easy to use with a built-in nozzle and deliver moderate R-values (typically R-2 to R-4.5).
• 20 oz. – 24 oz. (7–14 sq. ft): Found in Pro-grade options, these cans deliver higher foam output for contractors working on multi-application or larger jobs. They maintain R-values around R-2 per inch and require a foam gun for controlled dispensing.
• 5 gal. (200 sq. ft): Foam system kits are professional solutions designed for large-scale insulation projects. With R-values up to R-6, these are ideal for subflooring, crawl spaces, and full-room coverage where total thermal protection is needed.
