Mishawaka, IN - Cor-A-Vent Inc. introduces the next in a growing line of ventilation products for metal roofing, the new Sturdi-Spacer™ – a heavy-duty, breathable spacer strip for retro-fitting new metal roofing over existing shingle roofs.
Sturdi-Spacer installs in continuous rows, 2' on-center up the roof, like wood batten strips. The difference, though, is the airflow – Sturdi-Spacer allows over 3 square inches of net free vent area to create a breathable batten system between the two roofs, allowing trapped moisture to drain away and fresh air to pass through. With the creation of a minimum 1/8” air gap at the bottom of the roof behind the drip edge, Sturdi-Spacer will provide an extra boost of intake ventilation from the eave to the ridge, enhancing the performance of ridge/exhaust ventilation at the top of the newly-installed metal roof.
Sturdi-Spacer (product code: SP-1) is made from 5/16” (8mm) thick single-ply polypropylene plastic and comes in strips that are 2" wide by 4' long. They are power-nailable and power-screwable, and designed to not compress. Metal panels or hidden clip systems can be applied directly to the Sturdi-Spacer.
