Segments – Wood Frame

Wood Frame

STI is the industry leader in developing firestopping systems for wood-framed construction. Wood frame remains a very popular method of construction. Both cost effective and sustainable, wood frame structures for residential multi-family, dormitories, senior housing, and more are prevalent. Building codes, including the International Building Code® (IBC) and Canada’s National Building Code, include provisions for building out of wood, including structures up to five or six stories in height. As these structures soar to new heights, proper firestopping is essential, and STI can help.

  • Lumber Plate Designs
  • Membrane Penetrations
  • Acoustical Ratings

Choose the right sealant!

Wood shrinks, and that is a known fact. Buildings can also settle, and in some areas of the country, may need to be designed for seismic situations. That is why STI formulated WF300 Firestop Caulk, a product specifically intended for use in wood frame construction. During installation, the product is great for overhead applications and it offers excellent adhesion to wood and gypsum. Once dry, it forms a flexible membrane that can accommodate various building movements. Any gaps or voids that may develop due to excessive shrinkage or building settlement can be accommodated under fire exposure conditions because the product is intumescent and will expand with heat to form an insulative char. Most competitive products offered at the same price point are non-intumescent products, which should be avoided since they lack the ability to expand with heat and seal off any gaps or voids.

Plastic Pipe Solutions

Plastic pipe is common in wood framed buildings, and only STI has the most comprehensive solutions for wood frame buildings and plastic pipe. Our WF300 caulk is engineered to be safe for use with most common plastics, and STI has had products evaluated according to several manufacturers’ screening programs*. Additionally, our powerful line of intumescent wrap strips and firestop collars makes easy work of even the most complex piping systems. Capable of intumescent expansion up to 60x and backed by the most comprehensive package of UL Certified Systems, STI is the right choice for your next wood frame project!

*Please review Product Data Sheets and consult with plastic pipe manufacturers for more complete information on known chemical sensitivities associated with piping systems.

Lumber Plate Designs

STI knows wood frame construction, and our UL Certified Systems are diverse enough to cover a wide array of lumber plate designs. Systems are available for a variety of different conditions, including the following:

  • Standard 2 x 4, 2 x 6, or staggered stud wall framing
  • Single or double top plate designs
  • Discontinuous top plates bridged with steel nail protection plates
  • Square or round openings in plates
  • Rated or non-rated gypsum board

Not all products carry the same ratings or range of coverage, so it is important to consider the versatility of both the products and the associated UL Certifications. STI helps you rest easy; we have you covered.

Membrane Penetrations

Membrane penetrations are penetrations of service elements (e.g. pipes or cables) or boxes (e.g. electrical or utility) that penetrate a single membrane of a fire-resistive rated assembly. STI offers unmatched expertise. Here are a few of the common types of membrane penetration systems STI offers:

  • Complete membrane tests for metal pipes/conduits, plastic pipes/conduits, cables, and ductwork
  • Electrical outlet box testing for metal or plastic outlet boxes, metal or plastic faceplates, and ganged box configurations with putty pads or box inserts
  • Plastic washing machine outlet boxes
  • Large recessed electrical panels

Acoustical Ratings

When it comes to dwelling units, acoustics matter! The IBC® even has specific provisions for maintaining STC Ratings in these occupancies. STI products and systems are evaluated for acoustical performance to help maintain acoustical ratings.
