PRESS RELEASE 03/2017
NEW PRODUCTS FOR THE BAU 2017
NEW TYPES FOR THE IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER
ISO-Chemie surprised visitors to the BAU 2017 with two new variants of the IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER.
The three system types now available are tailor-made for different building situations. The flexible in front of wall installation system provides a suitable solution for the installation and sealing of windows in the insulating layer virtually every time.
Prefabrication of complete supporting frames using ISO-TOP WINFRAMER “TYPE 1” PREFAB
In order to optimise time and costs and make project-related prefabrication in the factory possible, ISO-Chemie has now introduced the “TYPE 1” PREFAB to its range. This is based on the successfully launched “TYPE 1” and has all its tried-and-trusted technical features and functionalities.
Project-related delivery lengths
One major advantage for installers using “TYPE 1” PREFAB is the fact that the PURATHERM system brackets can be produced individually to project-related lengths. Delivery in tailor-made project lengths makes it possible to prefabricate complete supporting frames for different window openings for a building project in your factory. Thus the respective window frames can be pre-installed in the prefabricated supporting frame together with a RAL-compliant sealing system.
Pre-assembled frame system
The in front of wall installation system ISO-TOP WINFRAMER “TYPE 1” PREFAB can thus be used for complete pre-assembly with a window element as a closed frame system. The four individual frame parts are delivered with a project-related cut length of up to 3,600 mm. ISO-Chemie has ISO-TOP WINFRAMER SYSTEM BRACKETS ”TYPE 1” PREFAB in the dimensions 80/80, 90/80, 140/90, 160/110, 180/110 and 200/110 (width/height) in the range for typical in front of wall installation applications. Since the system brackets can be ordered in building-related cut lengths of up to 3,600 mm, there is no residue on site and expensive adaptation can be avoided.
The corners of the 4-sided frame system can be mitre-cut or butt-jointed. The prefabricated ISO-TOP WINFRAMER INSULATING BLOCKS can be used for thermal insulation at butt-jointed corners.
ISO-Chemie supplies specially developed corner consoles made of metal for the mechanical connection of the four ISO-TOP WINFRAMER SYSTEM BRACKETS “TYPE 1” PREFAB to a prefabricated supporting frame. The ISO-TOP WINFRAMER CORNER CONSOLES are screwed in the rebate area and then covered with the movable insulating core. The optional ISO-TOP WINFRAMER CRANE EYELETS allow the ready-to-assemble facade element made up of a supporting frame and window frame to be transported by crane to the respective installation spot.
Simple on-site assembly
On the construction site, only a few steps are required to install the prefabricated supporting frame “in front of the wall”. Just as with the tried-and-trusted “TYPE 1”, the new “TYPE 1” PREFAB is glued to the outside masonry all the way round the window opening first using the system adhesive ISO-TOP FLEX ADHESIVE WF and then screwed in place. Subsequently, a segment of the movable insulating core is partially broken out via a pre-designed break-off line to positively fit the corner consoles and then fixed using a few adhesive points. The insulating core guarantees reliable integration in the EWIS by reducing thermal bridges.
Adjustment of the window frame
During the development of the IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER “TYPE 1” PREFAB possible building tolerances were considered, since, as is widely known, facade fronts rarely provide a perfect base that windows simply need to be screwed to. Pre-fixing of the window frame in the supporting frame of the in front of wall installation system is done from the outside. The screws for pre-fixing are offset to the window installation screws used later. This guarantees that the screws driven last will find a new firm base and not slip into an old screw hole. Once the facade element has been glued and screwed to the outer wall, the fixing screws can be removed from the outer side. The window frame, sealed using multi-functional joint sealing tapes for example, can then be “aligned plumb” and fixed in its final position using window installation screws in the IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER “TYPE 1” PREFAB from inside the building.
Optimised installation process
The use of the in front of wall installation system ISO-TOP WINFRAMER “TYPE 1” which is certified for use in passive energy houses, has been awarded the RAL quality seal and tested to RC 3 and TRAV requirements, brings numerous advantages, particularly where large-scale projects are concerned. Workflows in your factory can be optimised in terms of time and costs under controlled conditions. This saves money and makes costing calculations more reliable. Assembly in the factory – no matter the weather conditions outside – prevents any problematic assembly delays. Furthermore, assembly times on the construction site can be significantly reduced.
ISO-TOP WINFRAMER “TYPE 3”- the in front of wall installation system for large window elements
The other new member of ISO-Chemie’s IN FRONT OF WALL INSTALLATION SYSTEM family is ISO-TOP WINFRAMER “TYPE 3”. This type is made up of load-bearing, thermally insulating system profiles made of high-compressed THERMAPOR which are ideal for the direct installation of window systems in front of the load-bearing wall. Here, the excellent thermal conductivity of the moulded parts guarantees perfect integration in the EWIS and optimum Psi values. Thermal bridges can thus be optimised and a high degree of insulation achieved in the soffit area. This prevents the risk of mould formation in the connection area around the window opening.
The IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER “TYPE 3” can be used for the installation of windows in the insulating layer. The wind suction, dead and casement loads are absorbed directly by the ISO-TOP WINFRAMER SYSTEM PROFILES and transferred to the load-bearing wall. To achieve this, the ISO-TOP WINFRAMER SYSTEM PROFILES are glued directly to the masonry using the hybrid polymer-based system adhesive ISO-TOP FLEX ADHESIVE WF and additionally screwed in place. The mechanical attachment of the window elements is by means of standard window screws. Multi-functional joint sealing tapes or window connection foils from our ISO³-WINDOW SEALING SYSTEM range are ideal for sealing the windows.
Load-bearing capacity and load transfer in one
With the very high material density of 150 kg/m³ and outstanding load-bearing and thermal insulation properties, the system profile is ideal for in front of wall installation in single and multi-family homes and other building projects. The high density not only provides a very good load-bearing capacity for bearing window weights, it makes the material sturdy enough to transfer all other loads safely to the masonry.
The ISO-TOP WINFRAMER SYSTEM PROFILES can also be further reinforced using bearing brackets made of aluminium for another interesting solution. For this purpose, tightly fitting console slots have been integrated in the system profiles for the insertion of any number of consoles cut to length on site from extruded aluminium profiles. This can be an advantage particularly when very large elements are to be installed, very high casement loads occur or other additional requirements are made on structural design or attachment such as e.g. TRAV and ETB.
Optimum length adjustment
The system profiles have a dovetail connection on the end for quick and easy installation of the ISO-TOP WINFRAMER SYSTEM PROFILES. This allows the system profiles to be fitted together easily and practically. The joints are sealed using the system adhesive ISO-TOP FLEX ADHESIVE WF before the system profiles are fitted to the wall surface. There are special adhesive grooves in the butt joints for this. Suitable lengths can be prepared in advance in the workshop. For individual adjustment to the External Wall Insulation system, the ISO-TOP WINFRAMER SYSTEM PROFILES have a through groove on the front. This contains clamping fins to fix optional insulating bars and window sill moulds in place.
The 1,200 mm system profiles are available in two different dimensions. With a height and width of 80 mm each, ISO-TOP WINFRAMER SYSTEM PROFILE 80/80 are the perfect size for most applications. In addition, system profiles with a projection of 140 mm and a height of 80 mm are also available.
ISO-TOP WINFRAMER INSULATING BARS
The EWIS usually projects significantly beyond the window layer to the outside. In order to ensure a perfect connection between the ISO-TOP WINFRAMER SYSTEM PROFILES and the EWIS every time, ISO-TOP WINFRAMER INSULATING BARS can be used. These insulating bars 1,200 mm long are available in the standard dimensions 30/80 mm and 50/80 mm (width/height) as well as in window sill form. ISO-Chemie also offers custom solutions and tailor-made production depending on project requirements.
With its latest product innovations, the sealing specialists have once again proved their innovative strength in their jubilee year, where they can look back on 40 years of manufacturing Expertise.
