Xcell® Cellulose Insulation
Excellent R-Value
A home insulated with Xcell® cellulose insulation has fewer air leaks and uses much less energy than an identical home insulated with conventional batt insulation. This means reduced energy and cooling costs throughout the life of the structure.
Excellent Safety Features
Class 1 Fire Rating
Xcell® 's Class 1 fire rating meets or exceeds all requirements of local and national building codes. Its highly-efficient thermal barrier actually repels intense heat, and outperforms conventional insulation by forming a barrier to protect other more combustible construction materials.
All-Borate fire-retardent formula
Xcell® uses a 100% boric acid formulation for its excellent fire-retardant characteristics. Borates are naturally-occurring compounds that are harmless to humans when included in cellulose insulation.
No Man-Made Fibers to Irritate Skin and Lungs
There are no health concerns with Xcell® cellulose insulation. Since it combines recycled newsprint with a naturally-occurring, non-toxic fire retardant chemical, you can be certain it's a product you can live with.
Excellent Installation
Since Xcell® is blown into place, it completely fills in around wood framing members, electrical wiring, plumbing and other irregular areas. As the material exits the insulation nozzle, it’s misted with water to activate the product's adhesive characteristics.
Excellent for the Environment
Through a unique process, newsprint is recycled into today's highest quality, best performing building insulation. With Xcell, you dramatically reduce the amount of newspaper that ends up in landfills. And with its superior performance, your lower heating and cooling costs mean far less consumption of our non-renewable energy resources.
Excellent Sound Control
A home insulated with Xcell® is also quieter. Xcell® has excellent sound attenuation characteristics, so it’s useful in interior walls, too. You can quiet down a workshop, laundry room, recreation room, bathroom or bedroom — wherever you want to increase privacy and reduce noise transfer.
