Woodclad Product Data #W-1.3

General Description

Woodclad™ manufactured by Winter Panel Corporation, is a structural-grade stresskin panel with an interior wood facing of pine. Panels provide a complete roof or wall system, including both exterior and interior structural sheathings, high R-value insulation and a finished interior wall surface. The laminated construction affords tremendous strength and rigidity.
Only the highest quality wood facings are used in Woodclad panels, providing an extremely attractive, yet economical paneled wood surface.
The pine facing is kiln-dried to 7% moisture content – well below conventional standards for lumber – then milled to 6-27/32" width with tongue-and-groove routing. Any change in moisture content will tend to swell rather than shrink the boards, tightening joints between them.
The wood facings are permanently bonded to the stresskin panels using high-quality, durable adhesives. Groove edges of the facing boards are flush with the panel edge; tongues extend out past the edge for connection to adjoining panels.
The Woodclad panel system offers excellent insulation performance. High-density isocyanurate foam insulation (an advanced formulation of urethane) provides more insulation than 9" of fiberglass or 6" of 1-lb density expanded polystyrene (EPS).

Applications

Woodclad panels provide an all-in-one roof or wall system with a finished interior paneled wood surface. The most popular Woodclad application is roof systems for houses with cathedral ceilings and exposed timber or log rafters. Panels can be installed very quickly, with an entire roof often being closed in during a single day. No interior finish work is required after panels are installed.
At joints of the 48" wide panels, extending tongues on the wood facings fit into grooves on the adjoining panels, totally concealing the panel joint. For roof applications, Woodclad panels are generally installed horizontally, perpendicular to the rafters, with 4? panel end joints on rafter centers. This both conceals and strengthens panel end joints. Panels are secured into rafters using nails or screws from the exterior. Single 5/8 x 3" plywood splines, installed into routed grooves along the panel exterior, are used to reinforce panel joints. After panels are installed, a bead of foam sealant is injected in the pre-routed rectangular grooves in adjoining panels, assuring a tight seal.
Woodclad can also be used as wall panels in timber-frame and post-and-beam houses. For wall applications, all panels should be nailed or screwed into horizontal wood framing members (girts/plates and sills) along the top and bottom edges and into every vertical post along the wall (posts do not need to align with panel joints).
The tongue-and-groove configuration of facings on Woodclad panels allows panel waste to be kept to a bare minimum. By ripping panels at a T&G joint and carefully separating the facing boards so as to leave the tongue intact (tongue-and-groove joints are not glued), panel remnants can be fully utilized.

DIMENSIONS AND PHYSICAL PROPERTIES

OUTER STRUCTURAL SKIN: 7/16" Oriented strand board (OSB), a high-quality exterior-rated, wood composite board.

INSULATION CORE: Polyisocyanurate, a minimum 2-Ib/ft³ density, Class I, closed-cell foam. The foam insulation contains no formaldehyde or formaldehyde-related chemicals.

INNER STRUCTURAL SKIN: Identical to outer skin.

WOOD CLADDING:
Pine: 6-27/32"-wide by 3/4"-thick custom-milled, tongue-and-groove, pine boards, laminated onto the OSB panel. 7 boards per panel.

ADHESION: An extremely strong and durable bond between foam and OBS skins is provided by the continuous lamination manufacturing process with injected foam expanding against the two skins under pressure. Wood facings are bonded to the stresskin panels with durable cross-linked acrylic Type II adhesive.

STRUCTURAL INTEGRITY IN FIRE CONDITIONS Isocyanurate foam is a "thermoset" plastic. It retains its structural integrity until completely consumed by fire. Melting does not occur.

TOXICITY OF COMBUSTION PRODUCTS Dangerous gasses may be given off in a fire. Combustion products are similar to those produced by burning wood.
