Wall Construction
How Should We Build the NFPA 285 Wall?
Based upon the wall assembly you put them into, some walls will pass and some will fail. That is the problem that the architects have when designing a wall. They want to use a given foam with a given veneer, but it has to pass the test.
Manufacturers who have tested various combinations of their products in wall assemblies, can be very helpful. So specifying a specific wall assembly which has already been tested by the manufacturer will obviously spare the architect the time and money for testing, which can amount to a savings of thousands of dollars.
Tex Design Solutions is here to help the Architect with the decision process for the manufacture of their choice.

The International Building Code Orgainization
The International Building Code divides construction materials into five types as follows:
Type I: Noncombustible Materials and Structure
All exterior and structural components require fire-rated assemblies. Fire-protected steel and concrete assemblies are common.
Type II: Noncombustible Exterior and Components
Exterior walls, floors, and roof are composed of noncombustible materials. Steel, masonry, and cementitious products are common.
Type III: Noncombustible Exterior
Exterior walls are made from noncombustible materials and the interior building elements are constructed with any material permitted by code. Steel studs, fire-retardant-treated (FRT ) wood framing, and gypsum sheathing are common.
Type IV: Heavy Timber Construction
Exterior walls consist of noncombustible materials and the interior building elements are solid or laminated wood without concealed spaces. Wood members have minimum dimensions for Heavy Timber classification.
Type V: Combustible Construction
Structural elements, exterior walls, and interior walls are made from any materials permitted by code. Wood-based framing and sheathing is common.
