Arpex screw-in insulation anchors for EPS foam, pack of 12, threaded fixings for styrofoam

Arpex screw-in insulation anchors for EPS foam, pack of 12 are mechanical fasteners designed to securely fix expanded polystyrene (EPS) insulation boards to façades and internal insulation structures. The threaded body provides reliable grip in mineral substrates and common façade constructions, reducing reliance on adhesives and helping to stabilise panels during installation. Supplied in a set of 12, these anchors are intended to provide long-term mechanical support for thermal insulation layers where a screw-in attachment method is preferred.

Advantages

The threaded design ensures steady anchoring in porous and mineral base layers, improving holding power compared with smooth fasteners. Pack of 12 offers a convenient quantity for small to medium projects or repairs. These screw-in anchors enable faster installation by simplifying alignment and temporary support of EPS boards without large amounts of adhesive. Designed for mechanical load-bearing, they contribute to the durability of insulation systems when used according to substrate and spacing guidelines.

Suitable for

• Fixing EPS (styrofoam) insulation boards on external façades
• Internal insulation systems where mechanical fastening is required
• Renovation and repair work on mineral or masonry substrates
• Temporary stabilization of insulation panels during adhesive setting

Key specifications

• Fastener type: screw-in insulation anchor with threaded body
• Intended insulation material: expanded polystyrene (EPS / styrofoam)
• Quantity: 12 pieces per pack
• Application method: mechanical fixing into mineral substrates and typical façade constructions
• Primary function: mechanical support and stabilization of insulation panels

How to use

Select anchor positions according to the insulation system manufacturer’s spacing recommendations. Pre-drill a pilot hole if required by the substrate, insert the anchor through the EPS board and drive the threaded body into the base material until the anchor head sits flush with the insulation surface. Ensure the board is held uniformly against the substrate and check alignment before final tightening. Use appropriate tools and follow safety practices to avoid over-tightening, which can compress EPS and reduce holding performance.

Usage recommendations

Use these anchors in combination with the adhesive and mechanical fastening pattern recommended by the insulation board manufacturer. Verify substrate condition and load requirements before installation; avoid using the anchors in weakened or friable areas without preparatory repair.
