A two step vented Nailable Base insulation system that allows for staggering of the joints between the polyiso foam and the vented nailing panels. Staggering of the joints between the two components minimizes the risk of thermal short-circuits in the total system. This system also makes spacing the nailing panels easier, which allows them to expand properly. The nailing panels come with the required wood furring strips for easy installation of the system.
This product produces maximum air movement between the polyiso foam and the nailing surface. Utilizing small wooden blocks, this product allows for 92% air movement. This product is effective on roofs that have hips or valleys where complete ventilation is difficult without a system that lets the air move in multiply directions. Rmax Multi-Vent Nailable Base-3 ensures ventilation in all areas of the roof to comply with shingle manufacturer requirements.
This product is most often used in the roofing industry when recovering the roof of an existing building.
Re-Cover Board-3 is a rigid foam plastic thermal insulation board composed of polyiso foam bonded to glass fiber/organic mat facers on each side.
This product is designed for use in roofing applications where a non-permeable (aluminum) facer is preferred. Thermaroof Plus-3 is a highly efficient thermal insulation board composed of a rigid closed cell polyiso foam core bonded to reinforced aluminum foil facers.
