Installation
Many cladding systems require custom corner pieces, which are expensive and time-consuming to install. MagO cladding does not require these as the Bottom profile lip projection is the same length as the panel thickness. This allows for each elevation to have one field cut, ( easily facilitated on-site with a carbide tooth saw ), which will mate with the Bottom profile at each outside corner. It is best to seal this joint using adhesive caulking. Corners can also be constructed using flashings, angles and other methods, if preferred.
Ease of installation
- Inside corners are easily installed by butting one panel to the adjacent panel with a bead of adhesive caulk.
- The base rail and clips provide a 15mm drainage cavity, there is no need for rain-screen furring strips.
- At the top of each run, and at window and door openings the cut edge of the panel is supported with 15 mm spacer block.
- Trim-head screws are used in these locations to secure the panels. These are the only fasteners used on the face of panels and most of them will be covered with flashing.
- Due to their manageable size and light weight one worker can safely install panels.
Installation procedure system 1
Install the base rail perpendicular to the outside corner, the elevation depends on this base rail being at 90 degrees to the corners. Install an appropriate base flashing (not supplied). Fasten the base rail over the WRB using #8 corrosion-resistant round-head screws 12-inch O/C. Screws can be fastened into structural sheathing, finding studs is not required. If preferred, cover the drain holes with insect-screen.
Install the first panel to the left side so that it extends past the corner by 30 mm (1 ¼ Inch), this will allow the adjacent field cut panel to properly mate forming a clean corner.
Apply clips to the top of the panel, max 100 mm from the end and 600 mm apart. Clips may be used to bridge panel joints. If walls are untrue clips can be shimmed.
Install the remainder of the first-row full sized panels.
Measure the remaining elevation length and add 24 mm (15/16 inch)
Field cut the Top profiled vertical edge off of the panel for the right side of the elevation to this dimension. Use a thin kerf carbide or diamond tipped saw for best results, vacuum dust at source and wear a mask.
Orient the right-side panel with the cut edge to mate to the Bottom profile on the vertical edge of the adjacent elevation panel. Apply adhesive caulk to this joint.
Install the top clips following design spacing. Maximum 4 inch from the starting edge and 24-inch O/C. Clips at panel connections may bridge the joint.
Both elevations can be installed simultaneously.
At the inside corner run the first panel into the drainage channel enough to provide a bearing surface for the adjacent panel.
Install a through wall flashing every 6 courses or less.
At a window opening or top of wall cut the panel allowing room for air and flashings. Cut 4-inch spacer blocks from off-cuts and position as per clips. 24-inch O/C or closer. Use trim head screws into blocks, countersink and fill holes or cover with flashing.
Installation procedure system 2. Rigid insulation
Apply rigid insulation to sheathing with WRB using appropriate fasteners and / or adhesive.
Install cladding as per system 1, except.
Use longer screws to penetrate sheathing
Use longer clips and/or base plates to increase support, depending on wind-load and insulation density.
Installation procedure system 3. Aerogel
Apply Aerogel batts to sheathing using oversized washers and screws.
WRB is optional due to Aerogel’s hydrophobicity and permeance.
Install MagO Cladding as per System 2
Installation procedure system 4. VIPs
Apply as per System 1, except.
Install spacer blocks the same thickness as the VIP behind all clips and rails. These pieces must be the same size as the clips, i.e., 50 x 100mm (2-inch x 4-inch)
Install VIPs to bear on the spacer blocks, against the sheathing. Check for any sharp objects and remove them first, do not use fasteners, use only approved adhesive and tape. Do not pierce or puncture VIP panels
Between spacer blocks install other insulation, rigid, Aerogel, or spray foam.
Apply WRB over VIPs.
Install panel and apply clip, screwing into spacer blocks.
It is workable to install the VIPs as the Cladding panels are installed using overlapping strips of WRB.
Note: WRB helps protect VIPs from moisture, increasing their service life. In dryer locations this may not be necessary.
