Question:
Can this product be used on the underside of rafters, whilst maintaining a ventilation path between the rafters and sarking boards. There is no roofing felt beneath the slates - and large gaps in the barking which is 150 ears old…i want to avoid any condensation forming both inside the insulation - floor joists etc or outside the insulation on the rafters and sarking boards. (All of which are in good condition.) thanks Mark
Answer:
The SuperFOIL SF19BB Breathable Thermal Insulation is designed to be versatile and can be used on the underside of rafters. It's breathable properties allow moisture to pass through, thereby reducing the risk of condensation. However, for your specific situation with large gaps in the sarking and no roofing felt beneath the slates, you might want to consider some extra steps to ensure optimal performance and protection against condensation. Before installation, it's essential to ensure that any existing gaps or defects that could allow unwanted air or water ingress are sufficiently sealed. This could involve using a breathable membrane on your sarking boards before installing the insulation. For detailed installation instructions, you can refer to the product's Installation Guide which provides step-by-step guidance. Here is the link to the Installation Guide. Since every project is unique, it's recommended to consult with a professional or contact our technical team for advice tailored to your specific situation.
