Fiber-Lite and Fiber-Lite Plus Perfect Choice for DIY and Pros Respectively

Homeowners and Insulation Industry Professionals new to FTI Products may not be aware of the difference between Fiber-Lite and Fiber-Lite Plus. Overall, these two products are very similar. They have comparable R-Values, product densities, and meet similar ASTM* standards. Both products can be used in attics, walls and crawl spaces; they can be installed anywhere in a home or building. But there are a few key differences.

The subtle distinction is that Fiber-Lite Plus includes a dry adhesive that is activated by water. This is important only for wall cavity spray applications. For these projects, a professional insulation contractor is typically required since special equipment and a trained installer use a small amount of water when insulating the walls. After the product is installed, the activated adhesive will create a tighter bond within the insulation product and between the insulation-adjacent surfaces. This tighter bond enables the product to adhere more tightly, particularly in vertical wall applications. The ultimate benefit for the homeowner is that the wall has slightly better thermal performance by preventing air infiltration.

The picture above shows Fiber-Lite Plus being installed. You can see the main insulation hose and a smaller blue hose which represents the water line. It can be installed without the use of netting required with dry-blown cellulose insulation products in walls.

Fiber-Lite is a highly effective dry blown cellulose insulation that is suitable for DIY (do-it-yourself) or professional installations. It is typically used for attics. However, both Fiber-Lite and Fiber-Lite Plus can be used in almost every area of a home or building.
