Thermal Roof Sheathing

The glass fiber reinforcement contributes to improved fire performance and dimensional stability.

Thermal roof sheathing.

Thermax sheathing is a non structural rigid board insulation consisting of a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum facers on both sides. 7 16 osb is standard and 5 8 or 3 4 osb or plywood and fire pressure treated sheathing is available for special applications. This improved energy efficiency makes thermostat radiant barrier the ideal choice for new homes additions and renovations in warm to hot climates. Thermacal 1 and 2 ventilated roof insulation panels are composite ventilated roof insulation panels combining standard osb sheathing an air space made by solid wood spacers and polyisocynurate.

Made of a high density rigid polyisocyanurate core and coated glass fiber facer it combines the weather barrier and sheathing functions allowing completion of the building envelope to be faster and more cost effective. Roof sheathing basics the skeleton of a roof is formed with rafters or trusses generally spaced 16 inches or 24 inches apart from the center of one rafter to the center of the next. The standard 1 vent space layout leaves over 92 open vent area for maximum airflow. Thermo ply is manufactured to withstand the most rigorous of job site conditions.

Its core is constructed of 4 cross laminated plies that resist puncture breakage and vandalism.
