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.

External thermal insulation anchors: role, types and certification

Anchors designed to withstand strong winds

External wall insulation (EWI) anchors complement the bonding of the insulation. They absorb wind-induced pull-out forces and hold the system in place should the bonding fail. To ensure they hold securely, they must be suited to three factors: the substrate, the insulation and its thickness. The Centrale External Wall Insulation range:

  • LFM 10 hammer-in anchors (Klimas), from 140 to 300 mm. They feature a galvanised steel nail and an insulated head that minimises localised thermal bridging. They are covered byETE-17/0450, which applies to all categories of substrate.
  • LMX8 wall plugs, in 95 and 115 mm, for thin insulation layers.
  • Perfix wall plugs (10 to 30 cm).
  • Spiral helical wall plugs, which are screwed into the insulation.
  • TD-60 rosettes with cover, for screw fixing to timber studs.
  • 6 × 40 hammer-in anchors, for fixing the starter rails.
On mineral wool, a larger-diameter fixing plate is added (TDX-90 or TDX-140, as per the manufacturer’s specifications).

Length, number and installation of external insulation anchors

The right anchor, in the right place, at the right depth

The length of an external thermal insulation (ITE) anchor is calculated as follows: thickness of the insulation + thickness of the adhesive and the existing render + anchorage depth. For the LFM-10, ETE-17/0450 specifies an anchorage depth of at least 70 mm, in a hole 10 mm in diameter and at least 75 mm deep. With approximately 10 mm of adhesive, this gives: 100 mm 180 mm 120 mm 200 mm 140 mm 220 mm 180 mm 260 mm The number of wall plugs. Allow for at least 5 wall plugs per 1200 × 600 mm panel, i.e. approximately 7 per m², positioned at least 15 cm from the edges. In areas exposed to wind and at the edge of the façade, the fixing plan set out in the Technical Approval may require more. Installation:

  1. Fit the wall plugs after the panels have been bonded in place.
  2. Drill into hollow bricks using a non-percussion setting to avoid breaking their internal walls.
  3. In solid substrates, drill 10 mm deeper than the anchor and clean out the hole.
  4. Install at temperatures between 0 °C and +40 °C.
  5. Flush the head with the surface of the insulation, without pushing it in or allowing it to protrude.

How to choose your external insulation?

Steps involved in an EWI installation

Which fixing for which substrate?

External thermal insulation anchors: role, types and certification

Getting it right: the key answers

Des chevilles à frapper pour la plupart des supports pleins, des chevilles à visser pour les supports creux ou friables et les isolants épais. Les rosaces améliorent le maintien des isolants plus souples, comme la laine de roche.
Identifiez la nature du support (béton, brique pleine ou creuse, parpaing, béton cellulaire) : chaque cheville indique les supports pour lesquels elle convient et la profondeur d'ancrage nécessaire.
Comptez en général 6 à 8 chevilles par m² en partie courante, et davantage en rive et dans les angles du bâtiment, selon sa hauteur et son exposition au vent.
