## Long description

FISCHER dowel TERMOFIX PN 8 mm × 135 mm is a mechanical fixing solution for attaching thermal insulation boards made of polystyrene (EPS) or mineral wool to substrates such as concrete, brick and aerated blocks. Supplied in a pack of 100, the dowel is designed to secure external and internal insulation layers during facade insulation, thermal renovation and other insulation installation tasks that require durable mechanical anchoring.
Advantages
The TERMOFIX PN dowel combines a corrosion-resistant plastic body with a shape and length optimized for deep anchoring through insulation into the base material, reducing the risk of pull-out. Its 8 mm diameter allows reliable fixation with compatibility for standard fixing drives and tools. Supplied in a bulk pack of 100, the product supports efficient on-site work and consistent fixing spacing for thermal insulation systems.
Suitable for
 Fixing expanded polystyrene (EPS) insulation boards to masonry and concrete
 Securing mineral wool insulation in external wall insulation systems
 Thermal renovation of facades and replacement of insulation layers
 Internal insulation applications where mechanical anchors are required
Key specifications
 Dowel type: thermal insulation dowel designed for polystyrene and mineral wool
 Diameter: 8 mm
 Length: 135 mm
 Material: plastic/engineered polymer body suitable for long-term use in insulation systems
 Pack quantity: 100 pieces
How to use
Drill a hole through the insulation board and into the substrate using the recommended drill diameter for an 8 mm dowel. Clean the hole from dust and position the insulation board against the substrate. Insert the TERMOFIX PN dowel through the board and hammer it gently until the washer sits flush with the insulation surface. Ensure that the embedded length in the base material meets the project’s required anchoring depth. If needed, use corrosion-resistant fixing screws or caps compatible with the dowel to complete the mechanical fixation.
Usage recommendations
Choose drill depth and embedment according to substrate type (concrete, solid brick, hollow brick or aerated blocks) and follow applicable building regulations for thermal insulation systems. Store the dowels in a dry place and avoid prolonged UV exposure before installation. For projects with heavy wind loads or thin insulation layers, assess required fixing spacing and anchoring depth with technical guidance or manufacturer recommendations.
