STYROFOAM BRAND Insulation Inverted Wall Assembly Using the same material as conventional commercial construction this enhanced assembly is rearranged to attach STYROFOAM™ Brand XPS Insulation directly to the metal framing and then DENS ELEMENT gypsum sheathing is attached over the insulation. The Inverted Wall assembly is intended for Multi Clad buildings.



STYROFOAM™ Brand Spray Polyurethane Foam (SPF) Insulation -CM  is a two-component spray-applied foam insulation that creates a seamless, monolithic barrier for protection against water and air infiltration. Offered in two formulas, extends the spray season or ambient/substrate temperatures from 30°F to 95°F. It can be used for both new and retrofit applications, STYROFOAM™ Brand SPF Insulation expands during installation to fill cavities, cracks and crevices, sealing against uncontrolled air leakage and helping maintain consistent, comfortable indoor temperatures. The closed-cell, 2 pcf foam serves as both an insulation and air sealant for a wide range of applications throughout the building envelope.


The THERMAX™ Wall System is more than an insulated wall – it's a systematic approach to achieving efficiency at every level: simplified design, streamlined construction and optimized energy consumption for a reduced carbon footprint. Dow's three-in-one system with insulation, flashing and air barrier meets all applicable IBC and ASHRAE requirements. Each component of the THERMAX™ Wall System was selected to serve a particular function in the wall assembly. Together, these three simple parts – insulation, flashing and air barrier – work as one integrated system.




WEATHERMATE™ Sill Pan is a translucent, molded polymer that conforms to window openings. The durable polymer will not rust or rot and is compatible with standard adhesives and sealants. Dimensions: 5" h x 3-3/4" d x 32" w (each piece); sold as two-piece assembly that adjusts to fit most window sill widths.

WEATHERMATE™ Sill Pan is part of the complete WEATHERMATE™ Weather Barrier Solutions lineup from Dow – products designed to enhance the performance of the building envelope.



WEATHERMATE™ Plus – Housewrap is a non-woven, non-perforated, polyolefin-based housewrap that is both tough and tear resistant. It offers an effective option for builders who prefer to use non-insulating sheathing along with housewrap. When installed over sheathing in residential wall construction, WEATHERMATE™ Plus – Housewrap reduces costly air and moisture infiltration. WEATHERMATE™ Plus – Housewrap offers exceptional tear resistance and durability, and is translucent to allow a clear view of the studs and the sheathing surface during installation. It can be left uncovered for up to 120 days in the United States 


GREAT STUFF PRO™ Gaps & CracksGREAT STUFF PRO™ Window & Door, and GREATSTUFF PRO™ Wall & Floor are perfect for Pros, because they provide greater product yield and minimize waste. When you’re working with GREAT STUFF PRO™ products, GREAT STUFF PRO™ Foam Dispensing Guns can help you maximize control and access hard-to reach places easily and effectively. And since the GREAT STUFF PRO™ series is backed by Dow, you can be confident that you’ll get the job done quickly and thoroughly so you can get on to the next project.



Dow Froth Pak refills are the smart solution for contractors looking to add additional spray foam capacity without the expense of an entire second rig setup. Froth Pak refills also make sense for contractors looking to get into spray foam insulation services without upfront costs associated with drum foam rigs. Another benefit is that they are considered low pressure systems which means that you are able to enter the building within 1 hour after spray foam application. 50 gallon drum foam applications require 24 hours after application before entering the building.
​Froth Pak refills are available in 2060, 6860, 15430 and 43890 board feet of foam.


FROTH-PAK™ Foam Sealant is a two-component, quick-cure polyurethane foam that fills cavities, penetrations, cracks and expansion joints. FROTH-PAK™ Foam Sealant can also be used as a sealant and void fill in many roofing applications. FROTH-PAK™ is a chemically cured foam, which significantly reduces curing time. FROTH-PAK™ dispenses, expands and becomes tack-free in seconds. It skins over in 30-40 seconds and completely cures in minutes, depending on temperature.


TUFF-R Sheathing

Versatile TUFF-R™ Insulation fits numerous residential insulation and sheathing requirements and can be applied to a variety of substrates. It features a high-performance polyisocyanurate foam core with reflective foil facers on both sides (one side reinforced).


Super TUFF-R™ Insulation is one of the most durable - and thermally efficient – insulation products offered for residential applications today. Three-ply poly/aluminum foil facers laminated to the high-performance polyisocyanurate foam core enable exceptional durability and water vapor resistance. One facer is blue while the other facer is reflective foil.


THERMAX™ Sheathing is a non-structural, rigid board insulation consisting of a glass-fiber-reinforced polyisocyanurate foam core laminated between 1.0 mil smooth, reflective aluminum foil facers on both sides. The reinforcement, along with chemical modifications, contributes to fire resistance and dimensional stability. 



STYROFOAM™ Brand Rigid Foam Insulation
Rigid foam insulation from Dow is highly valued for a wide range of applications, from insulating buildings and geotechnical installations to enhancing thermal efficiency of panel and composite materials.
