New components provide extra support for window installation system
3rd February 2015

Extended reach and increased overhang of installed windows is provided following the addition of new components to ISO-Chemie’s thermal insulating and load bearing bracket system, ISO-TOP WINFRAMER.

ISO-TOP WINFRAMER system is based around a 1,200mm length pre-fabricated composite installation frame, which can be cut to size on-site and secured in position using an adhesive. This enables installers to quickly fit windows into the insulation area between the inner and outer walls, avoiding the need to use metal brackets which can cause non-repeating thermal bridging and give extensive problems when the windows need replacing.

Now, a selection of new system brackets have been introduced to provide increased overhang whenever necessary. These are available in three sizes: a 80mm wide x 80mm high bracket to fit the majority of UK window sizes and a 140mm wide x 90mm high option for deeper window profiles, or for use with combination products such as roller shutters.

A third bracket size (200mm wide x 110mm high) is ideal for reaches from 160mm to a maximum of 200mm, providing a robust, strong and high performance support frame with a high load-bearing capacity that’s capable of supporting heavier window loads as well as bi-fold doors.

Installation is quick with windows attached directly and secured mechanically using either standard fixing screws or fixing lugs in the usual manner. A hinged insulation core combines with the composite wood structural bracket to become an integral part of the overall wall structure, providing compliance with window energy saving regulations (EnEV) and the RAL quality assurance association.

New system boards, available in thicknesses of 30mm wide x 50mm high, 50mm wide x 60mm high, 30mm wide x 80mm high and 50mm wide x 110mm high, are available in a 1,200mm length for additional overhang capacity or incorporation in a front-of-wall installation system.

ISO-TOP WINFRAMER can be used with a range of ISO-Chemie foam tape sealant systems to provide effective and high performance window sealing. These include ISO-BLOCO One, ISO-BLOCO One Control, ISO-BLOCO 300 and 600, the ISO-CONNECT Vario range of self-adhesive foils and fleeces, and ISO-TOP Flex Adhesive WF for bonding and sealing to masonry and joint/corner sealing

A major end-user benefit of the new system is that when a window needs to be replaced at a later date it is not necessary to remove the internal plaster finish of the reveal wall to remove the old metal brackets and fit new ones, saving further disruption, refurbishment time and costs.

Resistant to temperatures between -50ºC - +100ºC, ISO-TOP WINFRAMER offers excellent acoustic insulation performance (up to 50dBA), high humidity resistance and can be over plastered for decorative finishes.
