Summary

A number of HCFCs, HFCs and hydrocarbons are proven to replace the blowing agent R11 in foam insulations. R141b, R134a and cyclopentane are mostly used, all giving an increased thermal foam conductivity compared with the original R11 blown product. Blowing agents with a better outcome are being investigated. Very efficient insulations can be obtained with advanced solutions like powders or granules in vacuum. In order to get more light-weight products in this category vacuum insulations are being developed with an open cell foam or structural elements inside to resist the external force as well as panels that contain a gas with a low thermal conductivity.
