PUCCS NC (NON-COMBUSTIBLE) (Patent Pending)

DuROCK’s PUCCS NC is the latest addition to the PUCCS series of Exterior insulated Finish Systems. The GDDC circular grooved PUCC-ROCK virgin wool insulation board has a 10mm deep air space required by building code and professional insurers. PUCC-ROCK non-combustible insulation and its integral reinforcing mesh are simultaneously fastened to the supporting wall using DuROCK’s liquid applied WRB’s and mechanical fasteners. The PUCC-ROCK insulation board effectively forms a water-repellant gasket around each fastener. PUCC-ROCK insulation boards are face-marked at 4 inch intervals to pinpoint stud locations, which makes this system much easier and faster to install. PUCCS NC has dual reinforcing meshes for increased impact resistance. PUCCS NC liquid-applied WRB’s effectively control air leakage, yet permit vapour diffusion to the exterior. PUCCS NC can be easily detailed to direct precipitation to the exterior.

PUCCS is continuous insulation cladding that includes a Geometrically Defined Drainage Cavity (GDDC) that is 10 mm deep and 37% open. PUCCS complies with National Building Code of Canada Subsection 5.9.4 (OBC 5.10.3) and Subsection 9.27.13, PUCCS complies with the CAN/ULC-S716.1 EIFS Materials and Systems test standard, PUCCS satisfies the test criteria in National Building Code of Canada Article 3.1.5.5 when tested in accordance with CAN/ULC-S134, and PUCCS satisfies the test criteria in National Building Code of Canada Article 3.2.3.8 when tested in accordance with CAN/ULC-S101.
