Canadian group lcynene Inc. has spent the last 25 years promoting its novel soft PU insulation foam as a good solution for the building industry. The group has done this via an extensive programme to educate architects and specifiers as well as by training a network of approved contractors to install the soft foam to high standards worldwide.
Most polyurethane insulation used worldwide is rigid material, so what is the value of the soft material?
Back in the 1980s we developed a water blown foam that was both an air barrier and breathable,” said Jeff Hood, vice president of international sales with lcynene Inc., based in Mississauga , Ontario.
The density of lcynene’s soft foam is 0.5 lb/ft3 as opposed to a density of 2 lb/ft3 for rigid,and the material, “lends itself to interior use,” he added, in a 1 March interview at the Ecobuild exhibition at the Excel centre in London’s docklands.
Hood noted that the details of lcynene’s technology and formulations are proprietary.
One valuable aspect with the water-blown foams is that the product does not need brominated flame retardants to push up its fire resistance, he claimed. Icynene has now broadened into spray and injected foams of low-medium density and closed- and open-cell types. But “the bread and-butter product is our open-celled foam,” Hood said.
The company has imitators but Hood said some of these products are hydrophilic, “whereas ours are hydrophobic. As to their…
