General Installation Notes

• Handle with care. Do not pick up or handle panels by the corners.
• Store panel boxes flat in clean, dry areas protected from the elements and from excessive heat, cold and humidity.
• Do not set or stack anything on top of cartons.
• Work panels with clean hands, tools, ladders, etc. on clean work surfaces. Wear clean, soft, white, cotton gloves to handle panel installation.
• Supersharp, stainless steel, smooth, long-blade insulation knives are ideal for making straight cuts, slicing through thick WILLTEC and SONEX panels. Shorter-length utility and extendable snap-off blade knives are best suited for making smaller detail cuts.
• For best results, cut panels through exposed-to-view panel faces.

Installation with acouSTIC

• Make certain that substrate surfaces to which panels will be applied are smooth, clean and level; free of dust, dirt and other residues or contaminants that could inhibit a strong bond to develop.
• Cut adhesive tube tips to produce a bead flow of ¼ inch (6.4 mm) diameter.
• Run a continuous bead of adhesive around the panel’s perimeter, approximately 1.5 inch (38 mm) from edges; then apply intermittent beads from opposite corners through the center of the panel creating an X.
• Press panels firmly into place and smooth evenly across them to ensure a strong, lasting bond; adhesive tack should be immediate.
