A Comparison of Breathable Multifoil Insulation

The introduction of Breathable Multifoil Insulation is a notable progression in the field of building technology, as it provides a distinctive blend of thermal efficiency and moisture control. Unlike conventional insulation materials, this product enables the passage of vapour while still retaining exceptional heat retention capabilities. Let's compare Breathable Multifoil Insulation. Breathable multifoil insulation comprises several layers of reflective foil and insulating materials, strategically designed to create a product that balances thermal efficiency and breathability. The top layers usually have a microporous membrane that permits water vapour to pass through while blocking any liquid water from entering. This design effectively tackles a common problem in building insulation, which is the build-up of moisture and irs resulting complications. The incorportation of foil layers plays a significant role in enhancing the insulation's overall thermal efficiency. These layers effectively reflect radiant heat, thereby reducing the amount of heat transferred through the building. As a result, this dual functionality helps to manage both conductive and radiant heat transfer, ultimately creating a more sustainable and comfortable living environment. It is worth mentioning that although all breathable multifoil insulations posses these common qualities, there can be significant variations in the properties thickness, and performance ratings of individual products, it is essential to comprehend these distinctions when choosing the most suitable product for your specific project needs.

YBS BreatherQuilt

BreatherQuilt is our highest performing breathable multifoil insulation, comprising of 11 layers. The first layer is made from true aluminium foil, which enhances its thermal properties. The core is made up of multiple layers of low-emissivity foil and fibrous insulation, strategically arranged to create air pockets that further enhance its thermal performance. The final layer is a breathable membrane that enables efficient transmission of moisture vapour, ensuring the insulation maintains its dryness and effectiveness over time. Technical Details Width - 40mm can be compressed to 7mm Approved Roof R-value - 1.62 m²K/W External Emissivity - 0.05 Vapour Resistance - 0.15 MNs/g Accreditations and Quality Control YBS BreatherQuilt has received approval from both LABC and BBA, indicating that it meets the requirements of building regulations.  

YBS Breathe-R

Breathe-R is a top choice when it comes to breathable multifoil insulation. It comprises of two layers and has a thickness of 2mm. The outer layer is made of a high-quality breathable roofing membranewhile the inner layer is a perforated aluminium foil for breathabilty. This particular multifoil has the lowest thermal performance but us the thinnest option available, making it ideal for situations where space is limited. Technical Details Width - 2mm Approved Roof R-value - 0.45 m²K/W External Emissivity - 0.05 Vapour Resistance - 0.15 MNs/g

YBS Breathe-R Ultra

YBS Breathe-R Ultra offers slightly better thermal performance compared to the original YBS Breathe-R. It comprises of three layers, with the first being a highly effective breathable membrane, followed by a layer of recycled internal wadding. The third layer is made of perforated true aluminium foil, allowing for optimal breathability. Technical Details Width - 11mm Approved Roof R-value - 0.71 m²K/W External Emissivity - 0.05 Vapour Resistance - 0.25 MNs/g
