Armacell Tubolit is widely popular among laggers in the UK and EU, and why not the pipe insulation is cost-effective, flexible and very easy to install. We recommend the tubolit range of pipr lagging 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 the pipework. Low thermal conductivity also means that the insulation does not let the pipes placed outside lose heat and freeze.

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

Acoustic Insulation: Tubolit from Armacell gives effective acoustic insulation to the pipework. 

Versatile Application:  Tubolit polyethene pipe insulation is mostly used as a lagging for indoor heating and plumbing applications. However, it can also be used as a short-term, inexpensive fix for outside pipework, if you are looking to protect pipes from freezing. It's also utilised in loft installations as it effectively protects the pipes in the loft areas from freezing over. Tubolit is a versatile solution that arrives split and ready to use, making it simple to apply to your piping.

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