Sold in packs of 20, these black foam closures provide a durable, weatherproof seal that resists UV, extreme temperatures, moisture, and pests.

Proudly made in the USA, these strips enhance the longevity and performance of metal roofing systems.

## Description

UPGRADE YOUR METAL ROOF: Duco's R panel foam closure strips are designed to keep rain, snow, rodents, insects, moisture, pests and much more out of any building or structure that has metal roofs. Each strip is incredibly lightweight and easy to cut and install under your metal roofing sheet and plugs the gaps of the roofing sheets when placed above the roof's eaves. Being that the strips are made from a polyethelene foam material and not styrofoam, rubber, plastic, steel, clear acrylic, fiberglass, vinyl or polycarbonate they can withstand high heat. Each strip inserts seamlessly at the edge of most PBR or R panel metal roofing systems and creates an almost decorative look in the way they blend into the shadow of the overhanging roof, acting as a perfect foam underlayment. In addition to all of the aforementioned features and benefits, these strips have a joiner (fasteners) on each side, allowing them to dock and clamp onto the end points of one another, making sure they stick together and can continually form an extension of one another. These do not come with sticky self adhesive fixtures. These closure strips are specifically for the 12” R Panel profile and WILL NOT FIT ANY 9” PROFILE.

Item is exactly as described. Pay attention to the V-pattern of your metal. If I would have purchased the correct one first, would have been better.
