Hammer-in anchors, helical anchors and rosettes: these mechanical fixings securely anchor the insulation to the wall and absorb wind loads on the façade. Centrale ITE offers external wall insulation (EWI) anchors with European Technical Approval, ranging from 95 to 300 mm, for concrete, brick, aerated concrete blocks and timber frames, at trade prices for both private individuals and professionals.
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:
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:
