Wraptite combines important properties of vapour permeability and airtightness in one affordable self-adhering membrane. It fully bonds to virtually any substrate, with a key benefit being its ease of installation, negating the requirement for sealants or tapes. It makes a significant contribution to a building’s thermal performance by preventing lateral air movement, but it also contributes to a healthy living environment and a healthy building thanks to its vapour permeability. With an Sd of 0.039m, it provides a high degree of vapour permeability in a commercial-quality, self-adhered, airtight breathable membrane.
