Product Information

Full details

The TIMco Metal PIR Insulation Fixings are designed for professionals and DIY enthusiasts needing to securely attach insulation boards to concrete, brick, and block substrates. They offer robust anchoring with a large head for secure retention and a minimum embedment depth marker for ease of installation, ensuring a reliable fit. A key caveat is their suitability only for clean, dry, low-humidity environments, and the requirement to tape and seal the head post-installation to prevent plaster damage.

FAQs

What substrates can these fixings be used on?

These fixings are designed for use with concrete, brick, and block substrates.

What is the maximum thickness of insulation these fixings can accommodate?

The maximum fixture thickness these fixings can accommodate is 250mm.

Can these fixings be used in damp or outdoor conditions?

No, these fixings have a Corrosion Rating of 1 and are only suitable for clean, dry, low-humidity environments. They are not designed for damp or outdoor use.

Why do I need to tape and seal the fixing head?

The head of the fixing must be taped and sealed after installation to prevent contact with wet plaster, which can cause surface damage.

How do I ensure correct installation depth?

Each fixing features a minimum embedment depth marker that you should align with the surface of the insulation board to ensure correct seating.

Are TIMco plastic cover caps included?

No, TIMco plastic cover caps are sold separately. They are recommended for use to reduce thermal transmission.

What is the minimum drill hole depth required?

The minimum drill hole depth required for these 8 x 300mm fixings is 60mm.

Troubleshooting

Fixing does not secure insulation properly

Ensure the drill hole is the correct diameter and depth. Verify the fixing has reached the minimum embedment depth marker. Check that the substrate is suitable (concrete, brick, block).

Difficulty driving the fixing

Confirm the pilot hole is clean and free of debris. Ensure you are using the correct size drill bit for the fixing.

Corrosion observed on the fixing

The fixing may have been installed in an environment exceeding Corrosion Rating 1 (clean, dry, low humidity). Ensure the product is used only in appropriate conditions.

Pros and Cons

Pros

  • Delivers strong and reliable anchoring for insulation.
  • Large head provides excellent holding power.
  • Installation is made easier with the embedment depth marker.
  • Durable construction suitable for its intended environment.
  • Helps improve thermal performance when used with cover caps.

Cons

  • Only suitable for clean, dry, low-humidity environments.
  • Requires additional step of taping and sealing the head to prevent plaster damage.
  • Not suitable for exterior applications or damp conditions.
  • Maximum fixture thickness is limited to 250mm.

Setup, Compatibility & Care Instructions

Setup:

  1. Determine the required drill hole depth based on the substrate and fixing size (minimum 60mm for this 8 x 300mm fixing).
  2. Drill a hole into the substrate of the appropriate diameter (typically 8mm for this fixing).
  3. Insert the fixing into the pre-drilled hole.
  4. Push the insulation material onto the fixing.
  5. Ensure the fixing is driven to the minimum embedment depth, using the marker on the fixing as a guide.
  6. Crucially, after installation, the head of the fixing must be taped and sealed to prevent contact with wet plaster. This protects the substrate and prevents potential surface damage.

Compatibility:

  • Substrates: Compatible with concrete, brick, and block.
  • Insulation: Suitable for rigid insulation boards.
  • Thermal Performance: Can be used with TIMco plastic cover caps (sold separately) to minimize thermal transmission.

Care:

These fixings are designed for clean, dry, low-humidity environments (Corrosion Rating 1). They do not require specific maintenance, but their longevity depends on being installed in the appropriate conditions. Avoid exposing them to moisture or corrosive substances.
