FAQs

Can I use this insulation on internal pipes?

While designed for external use, it is fully compatible with internal pipework, though it is specifically optimized for weather and UV protection.

What tools are needed for installation?

A sharp utility knife or insulation saw is sufficient for cutting, along with a compatible sealant or adhesive for the seams.

Is this product compatible with all pipe types?

It is sized for 28mm pipes, which are commonly used in heat pump systems regardless of the material, provided the outer diameter matches.

How often should I apply the maintenance coat?

The maintenance coat should be applied during your annual heat pump service, or sooner if you observe signs of wear on the outer coating.

Does this insulation prevent pipes from freezing?

It provides excellent thermal insulation to slow heat loss, but no pipe insulation can guarantee total freeze prevention in extreme, prolonged sub-zero conditions without a heat source circulating.

Troubleshooting

Insulation feels loose around the pipe

Ensure you are using the correct 28mm inner diameter size and use a high-quality insulation adhesive to secure the seam.

Water pooling near pipe penetrations

Re-apply PrimaryPro Bond & Seal to ensure the gap between the pipe and the wall is completely watertight.

Surface coating looking faded or brittle

Clean the surface thoroughly and apply a fresh layer of PrimaryPro Maintenance Coat to restore the UV resistance.

Pros and Cons

Pros

High-grade UV-resistant outer layer for durability
Fully waterproof to prevent freeze-thaw damage
Easy to cut and manipulate for complex pipe runs
Fully compliant with Part L building regulations

Cons

Limited to 28mm pipe diameter sizes
Requires specific compatible sealants for maximum performance
May require touch-up maintenance over long-term outdoor exposure

Setup, Compatibility & Care

Installation requires standard cutting tools and the manufacturer-recommended adhesive systems. To install, measure the length required, cut the section, and wrap it securely around the 28mm pipe. Always ensure all seams are sealed tightly to prevent moisture entry.

For wall penetrations, apply a generous bead of PrimaryPro Bond & Seal to the transition point. Maintenance is straightforward; perform a visual inspection during your annual system service to check for any physical damage or gaps. If the protective coating shows signs of wear, apply a fresh coat of the PrimaryPro Maintenance Coat to ensure the insulation continues to function effectively for another year.
