9 in Outside Foam Closure Strips for Metal Roofs - 20 Pack, 3 ft

In this review of the 9 in Outside Foam Closure Strips for metal roofs, the bottom line is simple: these foam strips are for homeowners and contractors who need an economical, effective way to seal R panel seams against wind, rain and heat transfer. The reviewer found the set of 20 strips, each 3 ft long, to be a practical solution when a precise fit and thermal performance are the priority. Installation was straightforward and the strips deliver the primary benefits promised: noise reduction, cold resistance and improved thermal sealing.

Key Features

• Superior materials: The foam is sturdy and cold resistant, which helps maintain its shape and sealing ability in low temperatures.
• Thermal performance: The strips provide heat insulation that reduces air leakage in winter and limits hot air ingress in summer, easing the load on HVAC systems.
• Waterproof protection: When fitted correctly to R panel profiles, the closures prevent rain and snow from entering roof seams.
• Noise reduction: The foam dampens metal-on-metal noises and reduces rattling during wind or thermal expansion.
• Value pack: The package includes 20 pieces of outside closure strip, offering coverage for multiple runs or spare parts for repairs.
• Long service life: Designed as a durable accessory, the foam strips are intended to last several seasons with normal exposure.

Who It's For

This product suits homeowners, farmers, and small contractors working with R panel metal roofing who want a low-cost way to improve weatherproofing and thermal comfort. It is especially useful for outbuildings, garages and agricultural roofing where long lengths of identical profile need consistent sealing.

Those who need a finished decorative trim, custom-shaped closures, or a pre-applied adhesive backing should look elsewhere; some buyers noted mixed experiences with adhesive availability and may prefer a version with factory-applied tape if ease of mounting is critical.

Pros & Cons

Pros

• Effectively seals gaps to keep water and wind-driven debris out when cut and set to the R panel profile.
• Helps reduce heating and cooling loss, which can lower seasonal energy use.
• Easy to handle and install; customers reported a good fit and straightforward trimming to length.
• Good value for the quantity provided in the 20-piece pack for larger projects.

Cons

• Adhesive strip is not consistently present on all packs, so extra sealant or fasteners may be required for some installations.
• Designed for Classic Rib R panels only; not universal for every metal profile without verification.
