YBS Breathe-R is a high-performance multifoil insulation and breather membrane designed to revolutionise how you insulate your home. Unlike traditional breather membranes, this 2 in 1 insulation and membrane offers both moisture protection and superior thermal performance in a single, easy-to-install solution.
YBS Breathe-R consists of 2 layers and is 2mm thick. It is manufactured using a durable and highly performing roofing membrane.
Key Features
- Dual-Action Technology: It functions as both a performing roofing membrane and a thermal insulation layer, allowing you to replace a standard membrane with a product that actually helps retain heat.
- Highly Reflective Surface: Manufactured using a highly reflective true aluminium foil, it works by reflecting heat back into the structure, significantly contributing to the reduction of heat loss.
- Breathable Design: The aluminium foil layer is perforated allows moisture to pass through, preventing condensation buildup within your timber structures while maintaining an airtight seal against the elements.
- High Thermal Efficiency: Provides an R-value of 0.45, which is equivalent to 20mm of mineral wool or around 30mm of some traditional materials. When used correctly, it can increase the reduction of heat loss by up to 39% compared to a traditional breather.
- Durable Construction: This heavy duty material is manufactured using a durable multi-layered composite, making it tear-resistant and long-lasting.
Applications
YBS Breathe-R foil insulation is versatile and specifically engineered for modern construction needs:
- Roofing: Ideal for both pitched and flat roofs. It is commonly applied over the timber rafters on a pitched roof to provide immediate weather protection and improved energy efficiency.
- Wall Insulation: Excellent for timber frame wall applications, where it acts as a secondary line of defense against water ingress while boosting the wall's high thermal resistance.
- New Builds & Renovations: Whether you are working on a new pitch or retrofitting an old property, these insulation roll Breathe-R Ultra 1.2m x 20m are designed to meet modern building regulations.
