Decking will normally require additional insulation to meet today’s energy codes. Rigid insulation or structural insulated panels can be installed over the decking to provide the desired insulating capacity.
Thermal Resistance Calculation (R) For Laminated Roof Deck Systems
Decking Thermal Resistance – R1
1R = Total thermal resistance of the assembly without roofing or air film resistance.
Examples of Typical Roof Assemblies
Roof Slopes Over 4:12
Roof Slopes Under 4:12
