In order to prevent the loss of energy and to meet legislator requirements, increasing numbers of exterior walls contain external thermal insulation composite systems. As these systems are usually incapable of carrying heavy structural loads, marquees and other attachments often need to be anchored in the construction material. The most commonly used construction elements, such as spacer sleeves or wooden or plastic subframes, often create unfavourable load conditions and thermal bridges.

The fischer Thermax 12 and 16 enables the structurally optimised installation of French balcony rails, marquees, conservatories and numerous other components, while thermal isolation allows its installation on outside walls, the front faces of ceilings or in ventilated curtain facades. The anti-cold cone made of glass-fibre reinforced plastic connects the zinc-plated anchor rod for installation in the anchoring substrate and the stainless steel threaded pin for mounting the console. This prevents a thermal bridge and related damages caused by moisture.

Variants with 12 and 16 mm threaded rod diameters (Thermax 12 and 16) are available for anchoring heavy loads in insulation thicknesses of between 60 to 295 mm. All common construction materials are suitable as an anchoring substrate. Installation doesn’t require any specialist tools, and all necessary components are included with the Thermax. 

Once the drillhole has been created, the anchor rod is individually adapted. Next, the plaster and thermal insulation is milled with the entire Thermax using the hexagonal bit. fischer provides a special milling blade for particularly stubborn plaster, which is simply placed on the cone. After the drill hole is cleaned, the anchor sleeve is inserted in perforated bricks. Next, the fischer FIS V injection resin is injected and the Thermax is inserted using slight turning movements. The fischer Thermax can still be adjusted after the injection mortar’s curing time, allowing anchor plates and consoles to be adjusted.  Afterwards, the annular gap between the plaster and the anti-cold cone is sealed with fischer DK sealant adhesive and the console or installation object is fixed with the hex nut to permanently and securely anchor the attachments.

Thermax types 8 and 10 can be used to firmly and securely install moderately heavy attachments such as awnings. They can “bridge” insulation thicknesses between 45 to 240 mm. They consist of the fischer Universal nylon plug (UX 10 or 12), a zinc-plated stock screw (M 8 or M 10) and a glass-fibre reinforced plastic cone. The annular gap around the fischer Thermax is sealed with a sealant adhesive and a special cap.
The plugs can be installed quickly without the need for any special tools. Minus tolerances in the wall structure of as much as 20 mm are easily bridged and compensated. Cutting spacer sleeves to size to fit conditions on site is also no longer required.

Thermax 8/10 fixings for various applications provide a diverse range of connection options: 4.5 mm to 6 mm chipboard screws, 6.3 mm sheet metal screws, as well as metric screws M6, M8 and M10. In wooden subframes, the fischer Thermax elements can be inserted directly without plugs.
