FAQs

Why is aluminium suitable for soffits in all climates?

Aluminium is ideal for various climates, including coastal and high-humidity areas because of it’s corrosion resistance which makes it suitable for harsh weather conditions, while also withstanding heat and cold without warping.

Does aluminium cladding on soffits affect energy efficiency?

Aluminium soffits can help with energy efficiency by promoting air circulation, reducing moisture buildup, and preventing heat from building up in the roof. Reflective finishes can also help mitigate heat in warmer climates.

Can using aluminium for soffits help with ventilation?

Our aluminium systems allow for a small space between the product and substrate which allows for airflow and ventilation. This ventilation helps prevent moisture buildup and condensation, which can lead to mold or structural damage.

Does aluminium on soffits contribute to fire safety?

Yes, aluminium is a non-combustible material, making it an excellent choice for soffits in areas with higher fire risk. It helps provide additional fire protection by creating a barrier around the roof’s edges.

Can our aluminium products be installed on existing soffits?

Yes, our aluminium cladding or batten systems can often be retrofitted onto existing soffits. A professional installer or one of our customer service reps can advise on how best to apply our products over the existing framework.
