Protect TF200 Thermo is a high performance breather membrane designed for protection of external timber framed walls during the construction process and provides secondary protection after construction minimising the risk of interstitial condensation. Its highly reflective and durable surface also enhances the thermal performance of the final wall construction. Protect TF200 Thermo is a high performance timber frame membrane with high tear strength, weather resistance and vapour permeability. Protect TF200 Thermo has all the features and benefits of the tried and tested Protect TF200 membrane, but with the addition of a highly reflective surface enhancing the thermal performance of the final wall construction. Low emissivity technology Protect TF200 Thermo provides a highly reflective yet permeable low emissivity layer. When installed facing into an unventilated airspace this effectively blocks infra red radiation and enhances the thermal performance of the airspace, and hence the overall U-value of the wall construction. Normal high emissivity airspaces are compared with low e spaces in the table below. Thermal resistance has been tested in accordance with BS EN ISO 8990. Properties Length: 100m. Width: 3m. Roll size: 300m2. Roll weight: 45kg. Weight: 150gsm. Brand: Protect. Certification: CE marked. Features Further thermal performance can be obtained using Protect TF200 Thermo in conjunction with Protect VC Foil insulating vapour control layer. Low emissivity reflective surface used to improve the overall u-value of the wall. Helps to meet the requirements of Approved Document Part L. Meets the permeability requirements recommended by TRADA and NHBC. Corrosion and damage resistant. Good nail tear resistance.
