For those who don’t cut corners. Paroc presents PAROC Hvac Bend AluCoat T, a stone wool pipe elbow insulation

Insulating heating and water pipes may not usually count among the most challenging installation works, however it certainly requires maximum precision, especially when it comes to pipe elbows. In order to make it easier for builders to design and construct complex HVAC systems, Paroc has developed high-quality, factory produced bends for efficient and fast insulation – PAROC Hvac Bend AluCoat T.

PAROC Hvac Bend AluCoat T is a non-combustible stone wool pipe section bend for thermal and condensation insulation of pipework in buildings and ships. Coming with a prefabricated layer of reinforced aluminium foil facing and tape in the longitudinal seam, the product effectively prevents condensation and makes it easier for installers to fit the insulation to the existing HVAC pipes.

Factory produced bends are ready-to-use solutions which ensure fast and easy fitting. Instead of cutting out individual pieces of pipe sections manually and fitting them back together to every pipe elbow in the installation, installers may use dimensionally accurate, prefabricated insulation components which improve the quality of the pipe insulation. PAROC Hvac Bend AluCoat T performs just as effectively as straight pipe insulation made with PAROC pipe sections, thus being a fully complementary solution.

Installing PAROC Hvac Bend AluCoat T is a technically effective, fast and economical way of insulating pipe elbows. Unnecessary heat loss is minimised due to the stone wool’s low thermal conductivity and the fact that no metal support is needed, which leads to further reduction of operational costs. This insulation method not only helps to avoid potential thermal bridges and heat losses, but also saves precious time.
