Install the can cell insulation in attics of homes to enhance comfort and convenience. Being lightweight, this insulation fills irregular cavities and stops air infiltration. The cellulose fibre blowing insulation is an extremely low, volatile and harmless chemical product. Its relative density makes it one of the best soundproofing products.
  • Weathershield meets all local and federal Canadian building code requirements whileamaintaining a higher value of insulating quality (R-value) than the same volume of any other insulation
  • Fills in the irregular cavities of your building and prevents air infiltration and convection
  • Relative density makes it one of the best soundproofing products on the market; perfect for dealing with loud work environments
  • Fire-resistant properties mean that a building will burn slower than the competitiveafiberglass or foam insulation

Yes, it is suitable for new wall insulation, however, you have to properly prepare the wall with the appropriate vapour barrier for performing blow-in insulation.

Can-Cell Weathershield ­R-3.8 Cellulose Blowing Insulation is rated 3.3 out of 5 by 6.
Rated 5 out of 5 by from Worked as intended I used this to top up my insulation, my wife was able to handle the bags without issue and I was able to use the hose to spread it throughout the attic. It was a little dusty but we were prepared with respirators and an ice fishing tent to contain most of the dust.

Rated 2 out of 5 by from Poussiéreur et peu pratique Produit de basse qualité. Il est indiqué qu'il est composé de 100% de papier recyclé et dans chaque sac que j'ai regardé, il y avait à chaque fois des petits bouts de plastique voir des lanières. Lorsque du soufflage, on entend même comme s'il y avait des cailloux dans le tuyaux. C'est possible que ce soit du papier agglomérer mais ce n'est pas mieux. Il est vraiment très poussiéreux. Ce qui est normal pour de la cellulose. Mais en ayant essayé une autre marque juste après celle-ci, on voit clairement la différence de quantité de poussière. Cela devient désagréable à l'installation. La cellulose est très fine en général dans les sacs. Elle est très compacte en plus et donc ce défait mal dans la machine de soufflage. Je ne recommande pas. Seulement en cas de dépannage et que vous n'ayez pas le choix. Je ne sais pas si la qualité moindre change vraiment l'efficacité de l'isolation, par contre.

Rated 1 out of 5 by from garbage i found a huge amount of dust, hard to clean up, lots of string the gets bound in the grinder, sounds like rocks in the product and the blower has a hard time breaking up the product.

Rated 4 out of 5 by from Épandage possible à la main. J’ai ajouté cet isolant par dessus mon isolant qui c’était affaissé avec le temps. Comme je suis une femme et que personne ne peut m’aider, la grosseur des paquets était idéal et assez facile à faire entrer dans le grenier. Le produit se défaisait facilement. Je n’avais qu’à le frotter entre mes mains. Il est vrai qu’il était très poussièreu, mais ce qui me rassurait était le fait qu’il était naturel. Un masque et des lunettes sont nécessaires pour ne pas inhaler de la poussière et ne pas en avoir dans les yeux.

Rated 3 out of 5 by from Gets the job done Easy to use with the provided insulation blow in machine. High amount of dust but non itching like fibreglass insulation. Would use this again
