ClassicBond 2 Inch EPDM Base Fixing Plate

The ClassicBond 2 Inch EPDM Base Fixing Plate is designed for use with insulation fixing screws to mechanically secure roof insulation boards as part of a flat roofing installation.

Measuring 2 inches in diameter, the fixing plate provides a larger bearing surface around the fixing screw, helping distribute the fixing load across the insulation rather than concentrating it around the screw head.

Ideal for mechanically fixed insulation applications, the plates provide a simple and effective method of securing compatible insulation boards to the roof deck before installation of the roofing system.

What Is an EPDM Base Fixing Plate Used For?

The ClassicBond Base Fixing Plate is used in conjunction with a suitable Insulation Fixing Screw to mechanically secure roof insulation.

The fixing screw passes through the centre of the plate and insulation before fixing into the appropriate roof deck or substrate.

The plate spreads the load over a wider area of the insulation board, providing a more secure fixing than the screw head alone.

Typical applications include:

• Flat roof insulation
• EPDM roofing projects
• Warm roof constructions
• Mechanically fixed insulation boards
• New flat roof installations
• Flat roof refurbishment projects

Use with Insulation Fixing Screws

The ClassicBond Base Fixing Plate is designed to work together with an appropriately selected Insulation Fixing Screw.

The fixing plate sits against the surface of the insulation board, with the screw passing through the plate and insulation into the roof deck beneath.

The correct type and length of fixing screw will depend on factors including:

• Insulation thickness
• Roof deck construction
• Required fixing depth
• Roofing system specification

Always select fixings suitable for the particular roof build-up and substrate.

Why Use a 2 Inch Fixing Plate?

Insulation boards are relatively soft compared with the structural roof deck beneath them. Using a fixing screw without an appropriate plate can concentrate the fixing pressure into a small area.

The 2 inch Base Fixing Plate increases the surface area around the fixing point, helping spread the load across the insulation board.

This creates a more effective mechanical fixing while reducing the tendency for the screw head to pull into or damage the insulation.

Mechanically Securing Flat Roof Insulation

Mechanical fixing is commonly used to secure insulation boards as part of suitable flat roof constructions.

The number and positioning of fixing plates and screws should be determined according to the insulation, roof system and project requirements.

Correct fixing is particularly important around roof perimeters, corners and other areas where wind uplift forces may be greater.

Always follow the relevant roofing system, insulation and fixing manufacturer’s specifications when determining fixing quantities and layouts.

ClassicBond Flat Roof Insulation Fixing Plate

The ClassicBond 2 Inch EPDM Base Fixing Plate provides a straightforward solution for mechanically securing compatible insulation boards within a flat roofing system.

Used together with suitable Insulation Fixing Screws, the 2 inch plate distributes fixing pressure across a wider area of the insulation, helping provide a secure and reliable installation before the remaining roofing system is applied.
