CONDENSATION CONTROL REFLECTASHIELD TF 0.81 Reflective Breather Membrane DESCRIPTION Reflectashield TF 0.81 is a high performance breather membrane specifically designed to enhance the thermal performance of timber and steel frame structures. Reflectashield TF 0.81 is a non-woven polypropylene film laminate, providing excellent emissivity and breathability, as well as secondary protection to the building during construction. The product is installed on the external face of the timber frame, foil side face out, similar to that of a traditional breather membrane but with added thermal benefits. The A. Proctor Group are constantly reviewing their product portfolio to keep up with current legislation. The A. Proctor Group have re-tested Reflectashield TF at the National Physics Laboratory (NPL) resulting in an increase of the claimed thermal performance to 0.81 m2K/W R-value. The resulting increase in thermal performance does not affect any of the high performance characteristics afforded by the use of Reflectashield TF 0.81. Reflectashield TF 0.81 complies with the vapour resistance requirements set out by BS 4016, TRADA and the NHBC. The existing legislation requires a breather membrane to have a vapour resistance not greater than 0.60 MNs/g. Reflectashield TF 0.81 has a vapour resistance of 0.44 MNs/g. PHYSICAL PROPERTIES Property Roll Sizes Water vapour resistance Sd Water penetration Class W2 (Before and After ageing) Before ageing: Tensile strength Reflectashield TF 0.81 must be covered as soon as practically possible on completion of installation. Any damaged areas should be repaired or replaced before completion. KEY FEATURES • R value 0.81 as tested by NPL. • Competitively priced. • Enhanced foil surface. • Unique patented three layer composition. • Low vapour resistance - complies with BS4016, TRADA and NHBC requirement. • Water resistant. • High strength to weight ratio. • Improved thermal resistance. • 1.45 & 2.7 metre wide rolls. • UK manufactured ensuring consistent supply. • Custom printed material available on request. Reflectashield is a vapour permeable low emissivity membrane for use externally on timber frame buildings. As such to maximise the thermal efficiency of the membrane the time of exposure should be kept to a minimum. However the membrane will maintain the function of a breather membrane in terms of water hold out for up to three months exposure. Mass per unit area The A. Proctor Group can provide a range of solutions, with U-values, down to as low as 0.17W/m2K in standard timber frame walling applications. Test Method Before ageing: Elongation Tear resistance
