Blow-in Insulation

Engineered Blow-In Insulation


The range of blow-in insulation from Knauf Insulation is a silicone treated, non-combustible glasswool which is designed to be installed by Approved Installers. Knauf Insulation are world-leaders in blow-in products and systems, and our products have been used in millions of homes throughout Europe and North America.

For many existing homes, blow-in insulation can improve the thermal performance of external walls without the expense and mess of removing and replacing wall-linings, and it can also be blown in internal walls and mid-floors to improve acoustic performance. Blow-in insulation is also a good solution for ceilings without insulation or as a top up to existing insulation to improve thermal performance and create a comfortable home. Blow-in insulation is an ideal solution where there is restricted space to install traditional insulation, and it offers superior thermal performance due to its ability to reduce thermal bridging by covering over all horizontal timber trusses and rafters.

The range of applications is not limited to the residential sector as it also provides a great thermal and acoustic solution for existing commercial structures, such as rest-homes, hotels and motels, offices and high-rise apartments where acoustic insulation was not installed during construction.
