How to install cellulose insulation?

Cellulose fibre insulation can be installed manually or with specialised blowing or spraying machines. Installation with machines usually takes place by a contractor, who brings to the installation site the insulation material and blowing/spraying machines. Due to the convenient installation method no cutting of the installation material is needed.

Blowing method

is most often used on horizontal and diagonal structures, e.g. on attics and floors. Blowing method can also be used for filling closed wall or floor panels in house factories or when adding insulation for renowated houses and buildings. The dry insulation material is blown into the cavity in question. The fine graded material penetrates well even the small holes and fills exactly and seamlessly the entire cavity.

Spraying method

is used on vertical structures, e.g. on walls. It can be done either in the house factory or on building site before closing the wall panel or wall part.. The insulation material is moistened with fine water dust while it is sprayed onto the open structure. A seamless and draughtless insulation layer is achieved even in small and difficult places. After drying the insulation is well adhered to the surrounding structures, which prevents sagging or separation from the structures.
