Wraptherm®
Wraptherm® is a composite comprising 10mm Spacetherm Insulation blanket bonded to the face of Wraptite vapour permeable, airtight self-adhesive membrane. Use of Wraptherm® provides improved airtightness levels combined with a reduction in thermal bridging. Wraptherm® was developed for use in the refurbishment of existing buildings where there was a requirement to enhance both the thermal and airtightness performance of the building. Wraptherm® can be applied to the internal face of the existing façade, providing a vapour neutral yet airtight layer, fully self-adhered to the substrate layer with the added benefit of a 10mm thick layer of high thermal performance Spacetherm insulation. Over this airtight/thermal composite framing can be installed with the cold bridging being reduced thanks to the Spacetherm layer. Additional thermal insulation can be included within the frame to meet the u values required for the refurbishment.

Installation
Spacetherm® WRB should be glued to the existing wall structure. Drilling is not recommended although it may be required for wiring and services. If drilling is required then care should be taken to compress the panel as much as possible to reduce the risk of insulation fibres wrapping around the drill bit.
Installation GuideInternal & External Reveal Angles
Spacetherm® WRB panels should be cut in such a way as to allow for the jointing of the plasterboard or fermacell and an unbroken run of insulation to the existing wall in both internal and external angles. Refer to Installation Guide for details.
Spacetherm Cold Bridge Strip
Spacetherm® CBS (Cold Bridge Strip) uses Spacetherm aerogel insulation encapsulated in polyethelene for use in the prevention of cold bridging through a component or element of a structure. Spacetherm CBS is an ideal specification when trying to reduce cold bridging in timber or steel frame structures. Upon request the Spacetherm CBS can be cut to a variety of widths to suit different applications.
Cutting
Spacetherm® CBS can be cut using scissors or knife. Care should be taken that cutting blades are kept sharp, if using a knife, the angle between the blade and the Spacetherm® CBS should be kept as low as possible. It is advisable to reseal the ends with tape after cutting is complete.
Fixings
Spacetherm® CBS is supplied with double sided adhesive tape for ease of installation. Spacetherm® CBS can be applied to either timber or metal framing systems.
