Installation without setting tool. This saves time.
Self-milling plastic cone.
Exact alignment of the attachment without pressure marks and damage to the ETICS.
Suitable for all building materials.
The advantages / Product description
The thermally separated stand-off installation in external thermal insulation composite systems (ETICS).
The stand-off installation allows for the fixture to be adjusted to the exact position required, which avoids pressure marks and damage to the ETICS.
The plastic cone creates a thermal barrier between the fixture and the inner fixture, and offers an energy-optimised fixing.
The glass-fibre-reinforced plastic cone cuts its own way through the ETICS with a positive fit, and allows for a simple and fast installation without the need for any special tools.
Combining with the universal plug UX provides secure anchoring in the substrate.
Without the UX plug, direct installation in a wooden substrate is possible after pre-drilling, too.
The fischer stand-off insulation system TherMax 8 is a solution for fixing into external walls without a thermal bridge in ETICS. The stud screw with the glass-fibre reinforced cone cuts its own way through the plaster into the insulation. During mounting, the stud screw is rotated into the universal fixing UX and is therefore secured within the building material. The anti-cold cone at the tip of the stud screw creates a thermal barrier and holds the outer fixing. The TherMax fixes light loads such as lights, letterboxes, or lightning conductors to concrete, aerated concrete, and masonry from solid and perforated brick.
Application and approval
For the thermally separated fixing of:
Blind guide rails
Vertically perforated brick
Hollow blocks made from lightweight concrete
Perforated sand-lime brick
Solid sand-lime brick
You can find detailed information on building materials in the registration document.
The TherMax 8 is suitable for pre-positioned installation.
The self-tapping, glass-fibre-reinforced cone cuts its own way through the plaster into the insulation during installation.
The anti-cold cone uses a thermal barrier to minimise heat losses.
Installation does not require any special tools.
For use in wood without a plug, the wood (see the footnote beneath the load table) and plaster must be pre-drilled: TherMax 8: d02 = 14 mm, h02 = 50 mm.
The assortment offers connection possibilities using M6 metric screws, 6.3 mm self-tapping screws, 6.0 mm chipboard screws, and 4.5-5.5 mm chipboard screws if using an SX Plus 5 plug.
