A warm roof and warm wall serve as innovative designs crafted to conserve heat effectively.


In these configurations, insulation is strategically positioned atop the deck, distinguishing them from conventional structures where insulation is sandwiched between rafters.


The waterproof membrane or top skin, whether it be roofing iron or wall cladding, is then laid over this insulation. This exterior insulation placement ensures that the house structure and ceiling, or wall space, maintain a similar temperature to the building interior, contributing significantly to warmth retention during winter months.

Warm roofs and warm walls are renowned for their efficacy, creating a comfortable interior temperature in winter and a cooler environment during the summer. The advantages and benefits of these designs extend beyond temperature regulation:

  • Thermal bridging is significantly reduced, thanks to the continuous insulation covering the entire roof and wall structures.

  • The necessity for roof space ventilation diminishes or decreases as the dew point temperature is positioned on the exterior side, minimizing condensation risks.

  • Energy efficiency receives a notable boost.

  • Reduction in heating and cooling costs, ultimately offsetting the initial investment over time.

Furthermore, the flexibility of warm roofs and warm walls accommodates various roofing and wall products, including membrane roofing (TPO and torch one) and an array of steel profiles such as corrugate, five rib, tray, and commercial profiles.


Embrace a holistic approach to insulation with warm roofs and warm walls, elevating comfort while promoting sustainable energy practices.
