Insulation Screw Panel Fixings for Timber – Box of 100

• These insulation screw panel fixings for timber are designed for the fast and secure fixing of rigid insulation boards directly into timber substrates. Suitable for applications where insulation panels are installed over timber frames, battens, or studwork, these fixings provide reliable mechanical anchorage with minimal installation time.
• Each fixing consists of a 4.5mm diameter mild steel pin, white zinc plated for corrosion resistance, combined with a polypropylene insulation head that distributes load evenly across the insulation surface. This helps prevent pull-through and damage to insulation boards, even when used with softer materials such as EPS, PIR, XPS, and phenolic foam panels.

Key Features and Benefits

• Purpose-designed for fixing insulation panels to timber

• Hammer-fix installation for quick and efficient fixing

• Polypropylene head reduces thermal bridging

• Wide head diameter improves load distribution and holding strength

• White zinc plated steel pin offers good corrosion resistance for external use

• Suitable for use on external wall insulation systems and timber-framed constructions

Installation Guidance

• These insulation fixings are installed by drilling through the insulation panel and positioning the fixing into the timber behind.
• The pin is then hammered into place, expanding within the timber to create a firm mechanical hold.
• As the fixing passes mainly through insulation material before anchoring into timber, hammer installation provides fast and effective fixing without the need for powered drivers.

Typical Applications

• External wall insulation fixed to timber frames

• Timber batten systems

• Timber stud walls

• Lightweight insulation panel installations
