Flat roof insulation techniques.

The insulation for flat roofs is commonly produced as rigid boards making them easy to handle and install with the variety of waterproofing types and systems. If insulation is being added to an older building then it is common practice for the ceiling itself to be taken down. Flat roof insulation is also used with conventional bur and mechanically or adhesively attached single ply and modified bitumen membranes when field applied cover boards are used. Rigid foam panels are available in thickness.

Warm roof is the best way to insulate your flat roof as there are no condensation issues to contend with. This will enable the airflow to circulate freely. The insulation material is placed between the supporting joists leaving a gap of 50 60mm between the roof and insulation. Ordinarily polyisocyanurate pir insulation is used within warm roof construction as it has excellent dimensional stability and compressive strength which enables it to withstand foot traffic without depression.

Use rigid foam insulation panels on your flat roof before applying the final roof covering or inside the house before adding sheetrock or paneling. Foam control plus flat roof insulation.
