Can you tell me a little bit about Handi-Foam products and explain what each one does?

Fireblock Foam Sealant (105739) is designed to seal, fill, bond and stop air infiltration. Handi-Foam Fireblock meets building code for type 5 inspection.

Handi-Seal (104086) has low expansion pressure and is closed-cell, so it does not absorb water and will not sag when wet. It seals windows and doors quickly and easily, and features a distinctive gray color. The thermal barrier will improve the seal of installed windows and doors.

Handi-Foam Kits (103304, 103305) fill holes and block against insects and rodents. This spray foam bonds to wood, metal, concrete brick and most plastics. Within 10 minutes it is tack free, can be trimmed after one hour and is fully cured after 24 hours.

Handi-Foam Two Component Kits (103465, 103466, 103463, 103309, 103310) mix in the nozzle of the dispensing unit and produce a moisture-resistant foam that conforms to any shape. The typical R-value is 6.2 per inch, and cured foam can be trimmed, painted or sanded.

Handi-Foam E-84 Class 1 Two-Component Kits (109627, 109629, 109625) contain flame retardants in order to meet the testing requirements of ASTM E-84, with a flame spread of 25 or less and a smoke developing rate of 450 or less. The flame-resistance rating meets the building code requirements for Class 1 materials.

Use Handi-Foam and Handi Seal to insulate your home or greenhouse - Growers Supply
Use Handi-Foam and Handi Seal to seal and insulate attic hatchways, ceiling floor, window frames, recessed light fixtures, soffits, plumbing vent stacks, corners of joining materials and window frames. Handi-Foam two component foam can be used to level, fill and insulate beneath tubs and showers.

What is the difference between one component foam and two component foam?

One component foam is used to fill gaps less than 3" (7.6cm) in size. It will extrude from the container the size of your pinky finger and expand to the size of your thumb. By shaking the can the polyol and isoyanate contents combine to create a polymer. When dispersed, pre-polymer reacts with outside humidity. The result is cured foam that is tack-free in approximately 10 minutes.

Two component foam is utilized in spray applications and for large void applications. This method utilizes two canisters each containing different agents. When the two components meet in the dispensing unit the nozzle mixes the two components and causes them to quick cure as rigid foam that is cuttable in 2-5 minutes and cures in less than an hour. It has an R-value of 6.2 per inch.

How are one component and two component foam typically used? What are some common applications?

One component applications include window insulation, door installation, skylights, air barriers, electrical outlets and fixtures, sealing around HVAC equipment, sealing agricultural structures, fixing small holes and other damage, sealing wall-ceiling joints, sealing wall-floor joints, plumbing, recreational vehicles, sealing vent penetrations and use as an air barrier. Additional purposes include adhering styrene panels, EPS foam to foam, adhering drywall and subfloor decking.

Two component foam is used in full home insulation, sound deafening, stage design, architectural molding, plumbing reinforcement, hot tubs/spas, pre-insulated pipe, recreation vehicles, structural support, cold storage, OEM, concrete block, bridge insulation, agricultural applications, metal buildings, transportation and hopper car sealing. It is also ideal for taxidermy, tank insulation, marine floatation, air barrier, sealing SIPS and building panel construction.
