Cel-Pak Cellulose Insulation

We are a Home Performance contractor that installs cellulose as one of our "tools" to increase the energy efficiency of a home. I like working with the Cel-Pak. It is a very clean and consistent product and I don't have to worry about it being caustic like those cellulose products that contain ammonium sulphate. view more + We are a Home Performance contractor that installs cellulose as one of our "tools" to increase the energy efficiency of a home. I like working with the Cel-Pak. It is a very clean and consistent product and I don't have to worry about it being caustic like those cellulose products that contain ammonium sulphate. I also feel good using it because it has just about the least environmental impact of any insulation. If we spill some on the ground, the rain will soon wash out the borate and then it can quickly compost, unlike other insulations that will stay around for a long long time. Tech support from National Fiber has been outstanding. view less -

This is one of the only companies that I have worked with in the last 30 plus years that actually cares about its customers-contractors. They help our company in any way they can. They are always there with answers and ideas. Meetings to help increase business. Training, tools and equipment and parts. I am overwhelmed by they way they think. view more + This is one of the only companies that I have worked with in the last 30 plus years that actually cares about its customers-contractors.

Our remodeling and energy retrofit company has used Cel-Pak cellulose from national Fiber on several projects. We have applied it as loose fill attic blanket and subcontracted for it to be blown in to cavities. I value the product for its resource virtues as it is made from a recycled product . view more + Our remodeling and energy retrofit company has used Cel-Pak cellulose from national Fiber on several projects. We have applied it as loose fill attic blanket and subcontracted for it to be blown in to cavities. I value the product for its resource virtues as it is made from a recycled product . It has less embodied energy than some other insulations and this includes the advantage that it is made locally so transportation is not a major factor. One doubt I have concerns the rate of application guidelines provided with the product. I have found that coverage calculations have not provided accurate quantities so that we have had to make additional purchases of material to achieve specified depth in loose fill application. This should be considered only a preliminary caution because we have not followed up with controlled testing to verify the discrepancy. view less -

Cel-Pak is an outstanding product. Among the things I love about this product : It has an 82% recycled content, it is produced in New England (specifically Massachusetts), and it offers an excellent barrier to air infiltration. It also does a terrific job in noise reduction. view more + Cel-Pak is an outstanding product. Among the things I love about this product : It has an 82% recycled content, it is produced in New England (specifically Massachusetts), and it offers an excellent barrier to air infiltration. It also does a terrific job in noise reduction. My research says that Cel-Pak is not only a great insulation, but cleaner and more eco-friendly than other cellulose insulations. It is also an 'all borate' formulation (in terms of fire resistance). When I insulated my attic, I didn't want to add any products that contained ammonia based fire retardants, and Cel-Pak, unlike a lot of competing cellulose products, doesn't. Great product! view less -

I just had this put into my house a few months ago and i never knew such a green product existed. I am told it has been around since the 1920s. My bills are half of what they used to be and the house is very quiet. I recommend this to everyone.
