FAQ: Insulating Your Metal Roof

What is the best insulation to put under a metal roof?

The National Construction Code (NCC) offers guidelines for insulation under metal roofs, emphasizing the importance of effective thermal resistance. Reflective foil insulation and blanket with foil attached insulation are commonly recommended options. Reflective foil insulation reflects radiant heat away from your home, while permastop insulation provides excellent thermal resistance, keeping your home comfortable year-round.

What is the best insulation for a corrugated roof - Choosing the Right Insulation Material

According to the NCC and Fletcher Insulation, a leading provider of insulation solutions, high-quality insulation materials that suit your area's climatic conditions are recommended. For metal roofs, reflective insulation or insulation blankets with foil attached are commonly used. These materials are effective in preventing heat transfer and are suitable for the narrow spaces typically found under metal roofs.

What is the most efficient insulation for a roof?

Roof insulation efficiency is crucial for energy conservation and comfort. Reflective foil insulation, in accordance with the NCC guidelines, is renowned for its efficiency. Reflecting radiant heat away from your home helps maintain cooler temperatures in the summer. It reduces the need for excessive air conditioning, contributing to energy savings and environmental sustainability.

Is sarking required under the Colorbond roof?

As per the NCC regulations, sarking, while not always mandatory, can enhance the performance of a Colorbond roof. Acting as a secondary barrier against water ingress and providing additional insulation, sarking improves weatherproofing and thermal efficiency, particularly in regions prone to extreme weather conditions. Incorporating sarking into your Colorbond roof installation can provide long-term comfort and protection.
