Fixing insulation

Fixing insulation : solutions pour l'isolation par l'extérieur

Fixing an insulation panel to a façade involves more than just bonding: additional mechanical fixing, using wall plugs, absorbs the wind-induced negative pressure loads throughout the system’s service life. Hammer-in anchors with metal nails, helical anchors and fixing rosettes meet the requirements of an external thermal insulation (ETI) project, from concrete substrates to hollow masonry, in both new-build and energy-efficient refurbishment projects.

SPIRAL 85 mm helical anchor for insulation

The SPIRAL helical anchor is a fixing designed to be screwed directly into the rigid insulation of external thermal insulation systems (ETIS), without the need for pre-drilling. Its 85 mm length allows it to secure lightweight items such as letterboxes, outdoor lighting or house numbers.

Its spiral design ensures a secure hold in the insulation whilst minimising the thermal bridge created by the fixing, providing a quick and cost-effective solution for low-load accessories on façades.

Hammer-in anchors with metal nails for fixing external wall insulation

A mount that stays secure, whatever the surface

Hammer-in anchors consist of a plastic body and a metal nail that is driven in with a hammer once the anchor has been inserted into a hole drilled perpendicular to the substrate. Designed to withstand wind suction loads – but never the dead weight of the insulation system itself – they can be installed on ordinary concrete, solid, hollow or perforated masonry, lightweight aggregate concrete or autoclaved aerated concrete, depending on the category of substrate covered by their technical assessment. Two installation methods are possible: for surface mounting, the flange sits flush with the render; for recessed mounting, a recess milled into the insulation houses the flange beneath an insulation plug for a flush finish, thereby preventing any hotspots or visible marks once the façade has been painted. The length to be selected depends directly on the thickness of the insulation installed and the required anchoring depth in the substrate: the thicker the insulation, the longer the anchor must be, with ranges covering standard thicknesses up to several tens of centimetres. The number of wall plugs per panel – generally between 3 and 9, depending on the site’s wind exposure and the height of the building – is determined by the fixing plan for the chosen ETICS system, without ever falling below the specified minimums or placing the anchors closer than 150 mm from the edge of the panels. A stock of various lengths allows for coverage of edges, corners and standard areas within the same building site.

Helical anchor and fixing rosette for external thermal insulation cladding

Quicker to fit, with no need for additional drilling

For building sites seeking a quicker, dust-free installation, a helical anchor is screwed directly into the substrate through the insulation, without first drilling a hole for the anchor body: its helical thread grips the substrate as it is screwed in, reducing installation time and minimising drilling dust, which is a real benefit on busy or renovation sites. A PVC fixing rosette with an integrated cover conceals the heads of the timber screws used when fitting accessories or additional framing to the insulated façade, ensuring a clean finish with no visible screws and preventing water ingress behind the fixed accessory. These solutions usefully complement the stock of hammer-in anchors for specific points and finishing touches on an external thermal insulation (ITE) project, whether for discreetly fixing a service box, a ventilation grille or a rainwater downpipe bracket.

How to choose your external insulation?

Steps involved in an EWI installation

Which fixing for which substrate?

Hammer-in anchors with metal nails for fixing external wall insulation

How many, where and how should they be installed?

As a rule, allow 6 to 8 anchors per m² in the main area of the wall, and more along the edges and corners of the building, where wind loads are higher. The exact number depends on the building height, its exposure and the system documentation.
Add the insulation thickness, the thickness of the adhesive and any existing render, then the anchoring depth required in the wall, given by the manufacturer for each type of substrate.
In most rendered external insulation systems, the insulation is first bonded and then anchored, especially on old, painted or weak substrates. On some new and sound substrates, bonding alone may be enough depending on the system.
