Bridging the gap with Kooltherm Cavity Closer
15/06/2010
Meeting the demands of modern construction requires something more than cobbled together methods of closing cavities around door and window openings. New Kooltherm Cavity Closer from Kingspan Insulation has been specifically developed to meet those demands simply and effectively, offering a unique combination of high levels of thermal efficiency with tested fire performance.
As buildings become more highly insulated, thermal bridging has a greater impact on heat loss and carbon dioxide emissions, and will be a significant factor in achieving compliance with the requirements of ADL1A 2010. Designed to maintain a continuous insulated barrier around window and door openings, Kingspan Kooltherm Cavity Closer has a rigid thermoset insulation core with an exceptionally low lambda value of 0.022 W/m.K, providing far better psi values than any other cavity closer in the same construction.
Another important attribute is fire performance; Kooltherm Cavity Closer has achieved over 47 minutes integrity and 41 minutes insulation with a PVC window in a UKAS accredited fire resistance test in line with BS 476 Part 20: 1987.
There are also a number of other benefits; the PVC–U J–section forms a positive integral damp proof barrier and key for the direct application of plaster, effectively preventing the problems frequently associated with traditional methods of closing cavities and thermal bridging. It avoids the need for cut bricks, blocks or special reveal blocks, thereby simplifying and speeding up the construction process and saving both time and money. It is weather resistant, easy to handle and install, and is unaffected by air infiltration. It is suitable for use with timber, metal or plastic window frames.
Manufactured in six sizes from 50–150 mm, the Closer can either be built in with frames or used to pre-form openings when frames are fitted later, helping to ensure the accuracy of opening sizes, it can also be supplied to order in curved sections. Jointing clips extend the range further by allowing the Cavity Closer sections to be joined to suit cavity widths of up to 305 mm. Kingspan Kooltherm Cavity Closer PLUS comprises sections of Kooltherm Cavity Closer factory pre–formed into a frame, designed specifically to reduce the labour and time involved in installing individual sections and allowing complete flexibility on specified opening sizes.
