EcoTherm develops and manufactures polyisocyanurate (PIR) rigid thermal insulation boards, helping to provide insulation for every construction need. we at Online Insulation are in a fortunate position to be able to offer this type of PIR (polyisocyanurate) insulation for less than other suppliers as we buy in bulk and pass our savings on to our customers.  The EcoTherm boards we provide have composite foil facing on both sides, and provide the perfect solution for any new build or upgrading thermal performance of existing buildings. Their insulation boards are recognised for their compressive strength, low weight, ease of installation and dimensional stability.
