Mounting set for polystyrene ELEKTROPLAST Kolek KWM-80 Ø18 mm 78 mm length 4 pcs

ELEKTROPLAST Kolek KWM-80 Ø18 mm 78 mm length is a mounting set designed for mechanical fixing of polystyrene (EPS) insulation boards on façades. The set includes four plastic anchors with a head diameter of 18 mm and a total length of 78 mm, intended for use with masonry or concrete substrates. These anchors are produced by ELEKTROPLAST for installation situations where reliable retention of thermal insulation layers is required.

Advantages

The anchors provide a stable mechanical connection between EPS boards and solid substrates, reducing the risk of insulation detachment. The 18 mm wide head offers good load distribution across the insulation surface, while the 78 mm length allows for sufficient embedment into typical masonry or concrete base layers. Being made of plastic, the anchors resist corrosion and are lightweight, simplifying transport and handling on site.

Suitable for

• Fixing polystyrene (EPS) insulation boards to masonry or concrete façades
• External thermal insulation composite systems (ETICS) where mechanical anchors are required
• Renovation and new construction projects that need durable mechanical fastening of insulation

Key specifications

• Head diameter: 18 mm
• Total anchor length: 78 mm
• Material: plastic anchor body suitable for use with EPS insulation
• Quantity per set: 4 pieces
• Designed for use with masonry and concrete substrates

How to use

Drill holes through the polystyrene board and into the substrate with a drill bit sized to the anchor shank. Insert the anchor through the insulation into the drilled hole until the head sits flush against the insulation surface. Fasten according to the system installer’s instructions, ensuring the anchor is firmly embedded into the substrate and the insulation board lies flat without gaps. Follow any additional ETICS manufacturer guidance for spacing, pattern, and number of anchors required per board.

Usage recommendations

Use the anchors in combination with appropriate washers or caps if required by your insulation system. Avoid using anchors in weak or heavily cracked substrates without prior reinforcement; test pull-out strength in critical locations. Store in a dry place and protect from direct UV exposure during prolonged on-site storage.
