Discuss compatibility issues related to wall and roof air barrier components for the myriad of air barrier and roofing assemblies that exist on the market today. And steel joist assemblies n beam designs for floor ceiling assemblies p roof ceiling designs s beam designs for roof ceiling assemblies u or v wall and partition designs x or y column designs ii. Kalwall fills spaces with well balanced natural daylight with the help of millions of prismatic glass fibers embedded in our panel s translucent face sheets. This can be done several ways.

Refer to our roof ceiling assembly documents which includes ul fire rated roof assemblies for easy guidance through the assembly of a roof or ceiling on your next project. Fire rated from one side and from both sides about the assembly. These wall assembly files are used for planning and estimation purposes for many ul wall types such as fire rated wall assemblies. Ok now onto the easy part the physics we are going to look at unvented attic and unvented enclosed rafter assemblies and then we are going to look at wall assemblies.

Describe why the roof wall air barrier intersection is critical to building performance in regards to moisture management and air leakage control and common design and field errors. Notice in the perfect roof assembly the critical control layer or membrane for rainwater control and air control and vapor control is located under the thermal insulation layer and the stone ballast i e. 1 hour wall assembly interek design no. 2 hour exterior wall assembly ul design no.

A extension of the firewall 30 beyond the roof vertically parapet construction b use of class a flame spread rated sheathing for 4 on each side of the wall where it intersects the roof deck c type x gypsum wallboard installed underneath roof deck 4 on each side of fire wall. These prisms refract sunlight to provide a balanced diffuse wash of glare free usable light deep within spaces. Roof cladding so that it is protected from the principle damage functions of water heat and ultra violet radiation. Sound tested with 2 x 4 stud wall with 1 2 12 7 mm toughrock fireguard c gypsum wallboard or densarmor plus fireguard c panels each side of assembly and 3 1 2 89 mm fiberglass insulation in stud space both sides.

The big deal with unvented roof assemblies is to control condensation or moisture accumulation on the underside of the roof sheathing. Usg provides resources here for our ul wall assemblies for seamless integration into any construction project. Flameblock with pyrotite facing out 2. Kalwall provides full spectrum natural visible light without distorting color rendition.
