Armacell combines safety and sustainability with improved fire behaviour for Tubolit® Split & DuoSplit


Armacell has achieved one of the highest fire performance ratings for its pre-insulated seamless drawn copper pipes. The enhanced safety of the environmentally sustainable Tubolit Split and DuoSplit products makes them ideal for use as part of the external air source heat pump systems that the government is encouraging in its drive to achieve carbon neutrality.

Pre-insulated with Armacell’s Tubolit closed-cell polyethylene, Tubolit Split and DuoSplit are designed for both domestic and commercial use. Versatile in application, they can be used to connect the indoor and outdoor components of split and multi-split air-conditioning systems, as well as being ideal for connecting to external air source heat pumps. The products are suitable for use with refrigerants R-410A and R-407C, as well as R-32 and R-290 in accordance with EN 12735-1. Whilst Tubolit Split is a single pre-insulated copper pipe, DuoSplit is a pair of flow-and-return pipes for use when the two follow the same route.

The certification comes at an important time for the UK, as the government has identified heat pumps as a key technology in the country’s drive to achieve net zero carbon emissions by 2050, stipulating that 600,000 units must be installed by 2028. It has extended the Green Homes Grant until 2022 and in 2020, initiated a £1bn Public Sector Decarbonisation Scheme. The Tubolit products’ new fire rating means that they can safely be used on the hundreds of thousands of new heat pumps being installed to provide sustainable heat for radiators and underfloor heating.
