Product Information
Full details
This guide is for builders, renovators, and insulation installers who need a reliable method for anchoring insulation to concrete and masonry. The key benefit is a secure, durable fix that ensures insulation stays in place, with a crucial caveat: the fixing head *must* be taped and sealed post-installation to prevent surface damage from wet plaster. This 8 x 250mm fixing system features an all-metal construction with a large 35mm diameter head and a galvanised finish for corrosion resistance, accommodating fixtures up to 200mm thick.

FAQs
What is the main purpose of this metal insulation fixing?
Its primary purpose is to securely anchor insulation materials to concrete, brick, and block substrates, commonly used in building and renovation projects.
Why is it essential to tape and seal the head of the fixing?
The head must be taped and sealed to prevent any contact with wet plaster. Failure to do so can result in surface damage or staining.
What is the maximum thickness of insulation this fixing can accommodate?
The fixing can accommodate a maximum fixture thickness of up to 200mm, making it suitable for various insulation depths.
Can I use these fixings in damp or outdoor conditions?
The galvanised finish provides corrosion resistance in clean, dry, low humidity environments. For persistently damp or highly corrosive conditions, these fixings may not be suitable, and alternative materials should be considered.
What does the minimum embedment depth marker signify?
This marker helps ensure the fixing is installed to the correct depth within the substrate, which is crucial for achieving a reliable and strong hold.
Are these fixings suitable for all types of walls?
They are suitable for concrete, brick, and block substrates. Ensure the substrate is sound and capable of supporting the insulation.
What is the size of the fixing head?
The fixing has a large 35mm diameter head, which provides a secure bearing surface for the insulation material.
Troubleshooting
Fixing does not anchor securely.
Ensure the drill hole is clean, of the correct diameter, and the minimum embedment depth of 60mm has been reached. Verify the substrate material is suitable (concrete, brick, block).
Surface damage observed around the fixing head.
This is likely due to contact with wet plaster. Ensure the head is *always* taped and sealed immediately after installation in applications involving plaster.
Difficulty inserting the fixing.
Check that the pre-drilled hole is clear of debris and is the correct size for the 8mm fixing. Ensure the substrate is not excessively hard or contains obstructions.
Corrosion observed on the fixing head.
The galvanised finish is for clean, dry environments. If used in damp or more corrosive conditions, or if the seal has failed, corrosion may occur. Consider alternative fixings for such environments or ensure a robust sealing method is used.
Pros and Cons
Pros
- Durable all-metal construction for long-term performance.
- Large head provides excellent holding power for insulation.
- Embedment depth marker aids installation accuracy.
- Suitable for a range of concrete, brick, and block substrates.
- Accommodates thick insulation materials up to 200mm.
Cons
- Requires post-installation taping and sealing of the head.
- Not suitable for wet or high-humidity environments without proper sealing.
- Galvanised finish may not be sufficient for highly corrosive conditions.
- Potential for surface damage if the head is not sealed against wet plaster.
Setup, Compatibility & Care
Setup:
- Drill a hole in the substrate material (concrete, brick, block) to the appropriate depth, ensuring it is at least 60mm deep (minimum drill hole depth).
- Insert the 8 x 250mm fixing into the pre-drilled hole.
- Push the insulation material onto the fixing until it is securely seated against the substrate.
- Crucially, tape and seal the head of the fixing with an appropriate waterproof tape and sealant to prevent contact with wet plaster.
Compatibility:
- Substrates: Concrete, brick, block.
- Environments: Clean, dry, low humidity.
- Maximum Fixture Thickness: 200mm.
- Optional: Can be used with TIMco plastic cover caps for enhanced thermal efficiency.
Care:
- These fixings are designed for permanent installation. No ongoing maintenance is typically required for the fixing itself, provided the post-installation sealing is correctly applied and remains intact. Regularly inspect sealed areas if there's a risk of moisture ingress to ensure the seal is maintained.
