CertainTeed FlintBoard CV Polyisocyanurate Roof Insulation is a rigid board insulation specifically for use over sloped unventilated roof decks.FlintBoard CV is designed to provide thermally efficient insulation with uniform cross venting that promotes the air circulation required by many shingle manufacturers. FlintBoard CV allows heat to dissipate while providing a nailable surface and efficient insulation in a one-step process.
FlintBoard CV is offered in a variety of thicknesses, and consists of a thermally efficient polyiso insulation board with 1.0", 1.5" or 2.0" ventilation channels separating APA/TECO rated OSB or plywood from the polyiso foam insulation to create a cross ventilating airspace. Flint board CV is made to order in 4' x 8' (1220mm x 2440mm) size panels and in nominal thicknesses of 2.5" to 6.0". Non-standard vent spaces are available on special order.
Do not leave exposed. Technical Information :- is a polyiso organic plastic foam and will burn if exposed to an ignition source of sufficient heat and intensity, or open flame, such as a welder's torch. Do not apply flame directly to FlintBoard roof insulations.
