Armacell Tubolit is widely popular among laggers in the UK and EU, and why not? These foam pipe insulation sections are cost-effective, flexible and very easy to install. We recommend the tubolit range of pipe lagging solutions from Armacell for the following reasons:

Thermal conductivity: Tubolit has a low thermal conductivity of 0.040 W/m·K, which means it will keep the heat inside pipework. This also means that hot water will remain hot, and just warm, so you do not have to re-heat water. Low thermal conductivity also means that these foam pipe insulation sections do not let pipework lose heat and freeze.

Make: Tubolit pipe lagging from Armacell is made with the highest quality polyethene in accordance with EN 14313. It is a low-density product with a very low water transmission rate. Foam tubing insulation wicks moisture and protects pipework from condensation and other moisture-related issues. 

Acoustic Insulation: Tubolit from Armacell also functions as excellent acoustic pipe insulation. 

Versatile Application:  Armacell pipe insulation is mostly used for indoor heating and plumbing applications. However, it can also be used as a short-term, inexpensive fix for outside pipework. It's also utilised in loft installations as it effectively protects the pipes in the loft areas from freezing over. Tubolit is a versatile pipe insulation solution. 

Environmentally Friendly: Armacell Tubolit is a long-lasting, sustainable and environmentally friendly product. Foam pipe lagging does not have any CFCs or HCFCs.
