WARMUS Insulation Board Fixing Washers - 35mm Galvanised Steel, Pack 100.
These 35mm-diameter washers are the industry-standard solution for securing underfloor heating insulation boards to timber or metal studwork. Designed to prevent 'pull through', these washers ensure the insulation remains flat and secure, providing a stable base for the heating system.
Key Features:
Large 35mm surface area: Specifically sized to spread the load and prevent screws from tearing through insulation boards (XPS, PIR, or cement-faced boards).
Corrosion Resistant: Manufactured from high-quality galvanised steel to prevent rusting in damp environments or screed-based installations.
Low Profile: The ultra-slim design ensures the washers fit flush with the board surface.
Universal compatibility: Designed for use with standard wood screws or drywall screws.
Diameter: 35mm
Material: Galvanised Steel
