Abstract
A method of applying fire resistant panel assembly to a wall is described. A first layer of fire resistant panels are applied to a wall. Each panel comprises a first planar surface, a second planar surface substantially parallel to the first planar surface, and an edge between the first and second planar surfaces. Each of the panels is attached to the wall such that the first planar surface is substantially parallel to the wall. A second layer of the fire resistant panels is applied to the first layer of fire resistant panels. Each of the panels of the second layer is attached to the first layer such that the first planar surface is substantially parallel to the second planar surface of panels in the first layer. The edges of panels in the first layer are substantially covered by panels in the second layer and edges of the panels in the second layer are substantially over panels of the first layer.
Description
Attorney Docket: 17901-21 IMPROVED SYSTEM AND METHODS FOR FIRE RESISTANT PANELS

BACKGROUND
TECHNICAL FIELD
100011 This invention relates to the use of panels on the surfaces of walls and roofs. In particular, this invention relates to use of a double layer of woven rock wool panels to improve fire resistance of walls.
BACKGROUND
[0002] Walls and roofs, in addition to providing structural supporting, provide barriers to the passage of elements into the building. Various coverings, cladding or layers added can block or slow water and wind.
[0003] Some wall coverings also improve the heat insulation properties of the wall, which can improve the energy efficiency of the building. Some wall coverings are susceptible to fire.
[0004] It is desirable to have a wall covering that is easy to install, provides heat insulation and is resistant to fire.
SUMMARY
100051 A method of applying fire resistant panel assembly to a wall is described. A first layer of fire resistant panels are applied to a wall. Each panel comprises a first planar surface, a second planar surface substantially parallel to the first planar surface, and an edge between the first and second planar surfaces. Each of the panels is attached to the wall such that the first planar surface is substantially parallel to the wall.
A second layer of the fire resistant panels is applied to the first layer of fire resistant panels. Each of the panels of the second layer is attached to the first layer such that the first planar surface is substantially parallel to the second planar surface of panels in the first layer. The edges of panels in the first layer are substantially covered by panels in the second layer and edges of the panels in the second layer are substantially over panels of the first layer.
BRIEF DESCRIPTION OF THE DRAWINGS
10006] In drawings which illustrate by way of example only various embodiments of the disclosure, [0007] Figure 1 is a perspective view of a wall system.
DETAILED DESCRIPTION
[0008] A wall generally typically is framed using studs 10, either steel or wood. The studs are typically oriented vertically with a fix spacing between the studs, typically 12", 16" or 24" and may be mounted in steel track 20 [0009] On the surface of the studs 10 facing the exterior of the building, sheathing, barriers or panels may be attached to provide protection from the elements.
These may include vapour barrier 50, insulated panels 60 or other panels. The wall system, is the combination of the wall and the barriers and panels that are affixed to the wall.
100101 As will be described below, it is desirable that the wall and the barriers and panels attached provide sufficient heat insulation to provide energy efficiency and that the wall system meet or exceed pertinent fire code requirements.
100111 In an embodiment, the wall system includes a fiberglass mat gypsum sheathing 40 secured to the exterior of the studs 10. The gypsum sheathing may be DensGlass or similar material that provides a solid surface with a fire rating based on thickness and may also provide moisture protection.
[00121 A vapour barrier 50 made of plastic, such as polyethylene film may be attached to the sheathing 40. The film may be adhered using glue or other means to reduce or eliminate the use of staples, nails or other modes of attachment that cause holes in the film. The vapour barrier 50 preferably blocks the transmission of air and water vapour through the wall system. The polyethylene film may comprise tri-woven layers.
100131 Foam panels 60 may be mounted to the wall using mounting tracks, such as using z-channels 70, as described in the applicants application 62/441,158 which is incorporated by reference. The foam panels 60 may provide insulation, both to heat transfer and sound. The foam panels may be made from polyurethane.
[0014] To the wall, fire resistant panels 80, 90 are mounted. The panels are preferably made of woven rock wool, such as sold by Roxul. In an embodiment, the panels are four feet by eight feed. The panels may be one and half inches thick. The material preferably has an R-value of approximately 4.2 hr ft2/Btu. The two layers of the woven rock wool panels may be mounted to the wall. If the panels are thinner, or have lower fire ratings, additional layers of the panels may attached.
[0015] A first layer 80 may be mounted such that the panels are oriented in a first orientation with the flat surface of the panels of the first layer mounted to the wall. For example, the first orientation may have the long dimension of the panels in the substantially horizontal.
[0016] A second layer 90 of the panels may be mounted to the first panel in a second orientation, with the flat surface of the panel parallel with the first layer.
The second orientation differs from the first orientation such that the seams 85 or joints between panels of the first layer are substantially covered by panels of the second layer.
Preferably, the panels of the second layer are mounted substantially perpendicular to the panels of the first layer. Similarly, the seams 95 of the second layer of panels 90 are substantially covered by panels of the first layer 80.
100171 If more than two layers of panels are used, the additional layers may be similar cross-laminated to cover seams of underlying layers. By having joints and seams covered, the layered panels reduce the transfer of flame and heat exposure to other parts of the wall system, including the foam panels.
100181 If, in an embodiment, the panels are square such that a first dimension is substantially the same as a second dimension, the panels of the second layer may be mounted offset from the panel from the panels of the first layer. Preferably, the panels of the second layer are offset from the panels of the first layer by approximately half the length of the dimension of the square panels.
100191 To the second layer 90, additional protective layers may be attached such as siding or other rain and weather resistant layer, which may also be referred to as wall cladding. The weather resistant layer may be affixed to the wall, and to the second layer of the fire resistant panel using a hat track 100 or other attachment means.
[00201 The first and second layers of the fire resistant panels may be mounted to the wall using a system of interlocking panels and support members as described in Application No. 62/441,158. Preferably the panels are mounted such that fasteners do not provide a thermal bridge through both the first and second layers. By reducing the thermal conductivity of the panels and the fasteners, the panel layers provide additional insulation and improve the fire resistance of the panels.
100211 Various embodiments of the present invention having been thus described in detail by way of example, it will be apparent to those skilled in the art that variations and modifications may be made without departing from the invention. The invention includes all such variations and modifications as fall within the scope of the appended claims.
