RetroFoam Injection Foam Tech Facts
specifications: retroFoam Foamed-In-place Insulation
RetroFoam wall insulation is designed for thermal and acoustical reduction. The product is highly cost effective as an insulating material. It is designed to be used in occupied residential and commercial retrofit applications. RetroFoam is particularly well suited for frame vertical wall applications.
POLYMASTER RETROFOAM PROVIDES:
- A non-expanding stable foamed-in-place product that is ideal for retrofit wall cavity applications
- High “R”Values and good acoustical and fire-resistance properties
- Low cost insulation
- Easy application
- Great results up to 6 inches thick
- A fresh product every time made from dry powder resins
RetroFoam is a new-generation tri-polymer resin which produces a non-toxic and odor-free material which is environmentally friendly. RetroFoam’s foaming process, uses two water-soluble components of a free-flowing
powdered resin and an aqueous based foaming agent.Compressed air is used to generate a dense, 60% closed-cell foam which is physically coated with the water-soluble resin. The foaming agent reacts with the resin within 10-30 seconds, transforming the foam in to a rigid, plastic solid when dry. This process is similar to the reaction of a two-part epoxy resin and produces a finished product that is inert, light-weight and nonflammable.
Unlike resins used for conventional foamed-in-place materials made from liquid formaldehyde and urea,RetroFoam’s kiln-dried-polymer resins are complete and only require mixing with water to make consistent foam every time.
RetroFoam reduces air infiltration by filling cracks and other voids as it flows into the cavity. Wires or pipes are not a problem since the product flows around them. RetroFoam is ideal for acoustical applications in party walls, conference room walls or patient exam rooms.
The RetroFoam product (resin) is shipped in dry powder form and has a shelf life of approximately one year. As needed, the resin is simply mixed with a prescribed volume of water, assuring consistent results without worrying about product shelf-life. During application, RetroFoam can be injected into a wall cavity through a hole as small as 5/8 inch and an be installed into drywall, frame, brick or block construction cavities. Final drying requires at least 48 hours or more. To assure proper installation, the application of RetroFoam must be performed by Polymaster, Inc. trained professionals.
ENVIRONMENTALLY "GREEN" CHARACTERISTICS
RetroFoam is an environmentally safe and friendly product made from nitrogen-based organic polymers. The foam is non-toxic and contains no solvents or petro-chemicals. Other “green” characteristics of Polymaster foam are:
- Biodegradable-no disposal problems
- No CFCs
- No ozone depleting off-gassing
- No container disposal problemsDoes not require potable water
- Ships dry-utilizes less energy for transportation
- Pollution prevention alternative to rigid foam boards
- No residues following incineration
