Info

Panel Dimensions Werzalit panels are engineered to accommodate expansion and contraction due to seasonal effects of temperature and humidity on its wood core. Panel ends are routed to form a shiplap end joint. It is not necessary for panel joints to end over a stud. NOTE: 1. The recommended gap between shiplap panel ends is 1/8” for temperate, cold or arid climates and 3/16” for tropical climates. 2. Panels installed in runs up to 36 feet long may be butted if normal expansion is provided at the end of the runs. 3. Joints up to 3/8” provide no technical problem, but may be unsightly. 4. To give the best appearance, gap spacing should be uniform throughout the job. 5. Work should be planned to avoid an excessive number of joints in conspicuous locations or an unsightly pattern of joints. 5
Cladding Application - General CLADDING INSTALLATION All Werzalit cladding and accessory installation shall be in accordance with approved practice and local building codes. STORAGE Cladding must be stored in a clean, dry area out of the weather and away from any damaging activity. All cladding bundles should be stored above ground on level blocking allowing ample space for air circulation. Covering should be used to protect panels from the elements during exterior storage. Wet boards should be removed from bundles to allow them to acclimatize prior to installation (stand boards on edge for several days, allowing air circulation on all sides). WALL SURFACE EXTENSION Existing wall surfaces must provide a flat plane for proper installation of Werzalit cladding. Irregular and unlevel wall surfaces should be brought to the attention of the project supervisor. CUTTING All Werzalit architectural products are easily installed with ordinary carpentry tools. When power sawing, a sharp carbide tipped saw blade should be used. Exposed edges of all cross cuts and cut-outs should be touched up with a top quality exterior color matched coating. NOTE: Always cut into the finished surface! SUPPORT FRAMING Werzalit cladding and accessories require a supporting framework with a maximum spacing of 2’-0” O. C. All sub-frame construction or support framing shall be no less then 5/8” thick, securely anchored and properly aligned to provide a flat plane for the cladding attachment. WALL PROTECTION An exterior moisture retarder shall be applied over the construction wall surface. Wall openings for windows, doors, louvers, etc. should be flashed according to the manufacturers instructions and good building practice to prevent moisture penetration between the fixture and the rough wall opening. LOW COMPRESSIVE STRENGTH SHEATHING MATERIALS Werzalit can be installed over low compressive sheathing such as plastic foam or foil faced materials, providing that the following conditions are met: 1. Cladding must be fastened through the sheathing, securely into the framing material. 2. The starter rail must be attached directly to the framing member, not foam sheathing. 3. Care must be taken not to overdrive cladding fasteners, or sheathing may be damaged by compression and wall surface may be uneven. EXTRUSION ACCESSORIES Install all extrusions as called by the architect. All extrusions shall be positioned plumb and level assuring proper alignment of cladding panels with all outline edges. PANEL PLACEMENT Place panels firmly together with tongue and groove mating fully. Panels can be seated fully by tapping into position with the end of a hammer handle. Before securing into position, make sure allowance has been made for expansion and contraction. Panel ends can be placed at random or placed in a preplanned pattern. EXPANSION AND CONTRACTION OF PANELS Werzalit has provided an engineered expansion and contraction system for its architectural panels. This allows the panel to “work” with climatic changes and allows the panel to be straight and smooth. For further details see page 8. FASTENING 1. When fixing Werzalit panels directly to wood framing, use stainless steel fasteners, with a minimum ¾” penetration into framing or solid sheathing. For application over sheathing or insulation board, fastener size and length shall be adequate to support panels and provide sufficient penetration (min. ¾”) into the framing material. 2. Whether by hand or power driven, a snug contact with the panel will secure installation. In all cases, avoid overdriving fasteners whereas this will hinder lateral movement of Werzalit panels. Fasteners shall be inserted at right angles to the panel to assure that fastener head is flush to the surface allowing next panel to be seated properly on tongue. NOTE: When power nailing use a finishing nail gun with air pressure not to exceed 85 psi Fasteners recommended by Werzalit of America, Inc. are a #7 stainless steel finish screw similar to those manufactured by Swan Secure, Inc.. Stainless steel nail fastener, ring-shank 8d, length to be determined by the installing contractor. TOUCH UP PAINT 1. Color matched touch-up paint is provided by manufacturer. All field cut ends and cut outs must be painted by the installing contractor. 2. When Werzalit of America, Inc. siding is installed against wood or synthetic trim it is recommended the exposed end of the siding board be field painted by the installing contractor before installation. 3. Weather caulking should be used to cover the expansion gap between the siding and the trim material. Color matched touch-up paint should be used to hide the caulking material.
