windows can be fitted in the outer thermal insulation level

The in front of wall installation system with integrated thermal insulating core

The IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER „TYPE 1“ makes it exceptionally easy to position and fit windows on the insulation plane. It comprises a load-bearing system angle made of PURATHERM and a highly thermally insulating core which can simply be  hinged out of the way during the fixing process.


In addition, the convenient insertion system makes installation even easier for wide or long rows of windows. The tongue and groove design allows the ends of ISO-TOP WINFRAMER SYSTEM BRACKETS to be fitted together easily and quickly, which means attachment work can be done by one person working alone. Other advantages include the fact that the practical tongue and groove connection makes levelling of the system brackets easier and gives the installed product a high-quality look.

Application Areas

For optimising the energy balance of passive energy and energy plus houses

The IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER „TYPE 1“ is an installation frame for optimising the Ψ-value. The wood composite profiles are suitable for bearing the loads of windows, balcony and patio doors.

In principle, the in front of wall installation system offers an optimum base for the energy-efficient sealing of window connection joints.



Optimum hold on the outer thermal insulation level

The IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER „TYPE 1“ wood composite profiles are pre-fabricated in 1200 mm lengths and can be cut to length on site using a mitre saw. Attachment to the wall is by means of a 1-component adhesive sealing agent matched to the wall, which guarantees optimum adhesion to mineral bases.


Wide range of applications thanks to different system components

In order to do justice to the special demands of cavity wall structures, brick facades and other installation situations which require larger projections, there is a range of different system components available for our in front of wall installation system ISO-TOP WINFRAMER. 



Use of the ISO-TOP WINFRAMER SYSTEM BRACKET, 80 resp. 90 mm wide and 80 mm high and adapted to the majority of standard window systems available on the market, is recommended wherever windows are fitted in the direct transition area between the wall and the thermal insulation composite system.



With a width of 140 mm and a height of 90 mm, the ISO-TOP WINFRAMER SYSTEM BRACKET 140/90 provides a larger projection. This version is suitable for deeper window profiles or for use with combination products such as roller shutters.


ISO-TOP WINFRAMER SYSTEM BRACKET 160/110, 180/110, 200/110

With a projection of between 160 mm and maximum 200 mm, this system component is suitable for use not only with thicker External Wall Insulation (EWI) systems but also on buildings with cavity wall systems and brick facades. Its large size copes well with the higher loads and thus provides long-term safety.



To supplement the system brackets of our in front of wall installation system ISO-TOP WINFRAMER, we also supply system boards in the thicknesses 30/50 mm, 30/60 mm, 30/80 mm, 50/60 mm, 50/80 mm and 50/110 mm, all of which are 1,200 mm long. The boards can be used for partial installation in the External Wall Insulation system and be adapted with the system brackets to achieve a greater overhang. We therefore offer you even more flexibility for your own installation Situation.


ISO-TOP FLEX-ADHESIVE WF is a high-quality, neutral cure, single-component, permanently flexible adhesive on a hybrid-polymer basis. It was developed especially for gluing the IN FRONT OF WALL INSTALLATION SYSTEMs ISO-TOP WINFRAMER and makes tension-free structural bonding of the system possible. ISO-TOP FLEX-ADHESIVE WF is also used for sealing and bonding corner connections and can be used on damp surfaces. Refer to the ISO-TOP FLEX-ADHESIVE WF product data sheet for further information.
