 | | NEW FIXING SOLUTION FOR EWI-CLAD WALLS FROM FISCHER | | | Fischer fixings UK Ltd | | 10/12/2007 | | | Fischer is introducing a unique new fixing solution specially designed for anchoring into walls which have external wall insulation (EWI).
EWI is increasingly common on properties of all types, especially public sector housing refurbishments, as it upgrades the thermal insulation characteristics of a building and also renews the aesthetics in one step. However EWI presents a notorious fixings challenge, when it comes to mounting external services.
The fischer Thermax provides a very strong anchor into any substrate and eliminates the problem of thermal bridging, which is caused by traditional methods of anchoring through the external wall insulation. The design ensures that the load is transferred to the building substrate itself, ensuring maximal load-bearing characteristics.
The fischer Thermax comes in two different versions. There is an M8 and M10 version which comes complete with a fischer UX universal nylon fixIng. This variant is ideal for light and medium-weight applications such as fixing downpipes, lights, signs, aerials and satellite dishes. There is also a heavy-duty version recommended for use with fischer FIS V 360 S resin. This is available in M12 and M16 versions and can take a loading of 2.5 tonnes. Its particular application is for the installation of canopies and awnings. It is sold individually and also in packs of three, since such awnings normally have three fixing points. All sizes of Thermax are available in a range of lengths and can be used in virtually any building substrate.
Traditionally, fixing into EWI-clad walls has involved stand-off installation methods, such as spacer tubes or wooden blocks. These methods tend to be time-consuming to install, while not necessarily giving a very strong fix. Additionally with such techniques, every threaded rod inserted or bracket fixed entails creating a cold-bridging path through the thermal insulation.
The fischer Thermax however has none of these disadvantages due to its unique design. It features a glassfibre reinforced high-performance anti-cold cone to interrupt the heat flow through the threaded rod. This cone is self-tapping, and during installation cuts its own way into the insulation. This allows economic installation without the need for special tools.
The threaded rod is infinitely adjustable to allow uniform installation when fixing to even or uneven surfaces. All external parts are manufactured from stainless steel to guarantee maximum durability.
“Thermax is a totally unique product from fischer,” says David Harvey, EWI manager at fischer fixings UK Ltd. “There is nothing else on the market which gives these types of loads into externally-insulated walls, while also not compromising the insulation of the structure. We believe this product will find an enthusiastic audience, due to the rapid growth of EWI techniques.” | |
