What width is the correct width for thermal break??

To eliminate heat loss and heat gain through the steel frame to the exterior cladding, there has been a lot of energy studying what width Thermal Break is required.

The width of Thermax B® is dictated by the width of the steel frame it is being attached to.

Working on the minimum optimum and maximum scenario for choosing the right width Thermax B® .

(If steel frame was 40 mm in width)

Minimum = 5mm oversize of framing (45mm) only deals with conducting heat

Optimum = 30mm oversize of framing (70 mm) this deals with both conducting and radiating heat transfer

Maximum = full sheets – adds to the overall insulation value of the wall.
