Type-RFeatures• Waterproofing, Insulating and Self Locating inone fully assembled piece.• TYPE-R’s unique design incorporates a flexiblewater seal which reduces the possibility ofwater penetration. (in robust detail)• Robust, easy to use on-site and can be cut tosize and jointed, minimising waste.• Eliminates the need for blockwork to close thecavity.• Both are CFC & HCFC Free - TYPE-R brick tie -kind to the environment.YBS Type-RType-R can be installed in a variety of ways• Tack to window frame if built-in• Built-in as work progresses using special ties (see fig. 2)• TYPE-R can be installed after the reveal has been constructedby fixing to the inner leaf using holes provided.Vertical JointingIf required, sections of (Therma-Close) TYPE-R can be jointedto minimise waste. All joints must be tightly butted - 45ºdown wards towards the outer leaf. This will stop potentialwater penetration.TYPE-R and Type-R Fire-Stop are specially designed tocreate a more rigid water proof cavity closer system.TYPE-R and Type-R Fire-Stop comprise two rigid extensions,one of which has a unique, flexible, water seal.Once the window is in place the flexible seal sits againstthe window frame and acts as a secondary water seal.These two rigid extensions allow TYPE-R and Type-RFire-Stop to be made to any cavity width. TYPE-R andType-R Fire-Stop are now available for both standard andcheck reveals to suit Robust Details.YBS TYPE-R and TYPE-R Fire-Stop ties are also availableto enable, if required, the closer to be built into bothleaves. TYPE-R and TYPE-R Fire-Stop is designed tobe used in door thresholds and both jambs and cills ofwindows, this provides a total solution to cold bridgingproblems associated with openings in traditional cavitywall construction.Corner JointingWhen jointing horizontal to vertical, trim both PCV flangesand allow the vertical to extend below the horizontal - thisstops water ingressCheck Reveal & Robust DetailsThe diagrams below shows a window jamb in a masonrycavity wall, with Type-R and Type-R Fire-Stop closingthe cavity. Robust details require a cavity closer with aminimum Thermal Resistance Path of 0.45m2K/W .The approach used to calculate the thermalresistance of its minimum thermal resistancepath was in accordance with the guidancegiven in BRE IP 8/08. The minimum thermalresistance calculated for Type-R is 0.865m2k/wContinual demand for greater thermal efficiency has leadto the reduction of the ‘U’ value requirements of structures,emphasised in the recent revision of Building Regulations(L1 & L2) and Building Standards Part J. TYPE-Rand TYPE-R Fire-Stop are designed to offer the perfectsolution for the specifier to satisfy this requirement.The only rigid Cavity Closer availablewhich creates a secondary water sealby use of a flexible strip.
