Q: Can this sleeve be used for both hot and cold pipes?

A: Yes. The closed-cell rubber foam construction is engineered to reduce thermal transfer on both hot and cold medium pipes, minimising heat loss on warm pipes and preventing condensation on chilled lines such as air conditioning refrigerant tubes.

Q: Is this pipe insulation sleeve easy to install?

A: Absolutely. The sleeve is highly flexible and can be slid directly onto pipes or slit lengthways and wrapped around existing pipework. No special tools are required, making it ideal for home DIY and professional installations alike.

Q: Is this product safe for use in enclosed spaces such as walls and ceilings?

A: Yes. This sleeve features built-in flame-retardant properties and is fibre-free, meaning it produces no dust and will not harbour mould or other harmful substances — making it safe for use in enclosed spaces in residential and commercial buildings.
