DATA SHEET Reﬂectatherm Plus REFLECTIVE VAPOUR CONTROL LAYER Reﬂectatherm Plus is a reﬂective, high resistance vapour barrier for internal walls, ceilings and ﬂoors, speciﬁcally designed to enhance the thermal performance when placed on the warm side of the insulation. PHYSICAL PROPERTIES Property Roll Size Mass per unit area Water vapour resistance Sd Vapour resistance Water penetration Class W1 (Before and After ageing) Tensile strength Tear resistance The membrane should be installed with the foil side facing the cavity. In ceilings the product is placed between the underside of the rafters and the ceiling lining. In ﬂoors the product is placed on top of the structural decking or insulation (where present) and below any screed or sensitive ﬂoor coverings. Adjacent sheets should be lapped by 150mm and sealed with a suitable tape. Minimise penetrations caused by services and seal all joints. Test Method Mean Results U Value - Performance Ready Reckoner Stud Reﬂectashield TF Reﬂectatherm Plus Reﬂectashield TF & Reﬂectatherm Plus * When utilising rigid insulation boards between studs, accommodation for services should be considered. The above calculations are based on fully ﬁlling the stud with insulation and the provision of a service cavity. KEY BENEFITS > High vapour resistance. > Improved airtightness. > Creates service void. > Creates an unbroken vapour control layer. > Improved thermal resistance. > R value of 0.79 m2K/W when used with a minimum 19mm service cavity. > Vapour Resistance of 750 MNs/g. > Help meets the requirements of the Part L in England and Wales, Section 6 in Scotl
