General Installation Notes:

  • When cutting CONTOUR, HARMONI or WHITELINE tiles, best results are achieved when cutting is done from the back side.
  • Be sure to lay tiles on a clean surface before cutting.
  • For best results use a sharp razor or fixed-blade knife and metal straightedge. Cutting with a dulled blade can
    produce a rough, unsightly edge. The knife blade should be long and sharp enough to cut evenly through the entire thickness with a single measured stroke.
  • An electric carving knife is the perfect tool for cutting and trimming CONTOUR, HARMONI and WHITELINE
  • When making free-hand cuts to fit the tiles around an obstruction, it is usually better to undersize the cut,
    then test fit and trim off more of the tile as needed for an accurate fit.
  • Store all cartons right side up and flat in a clean, dry area, enclosed and protected from the elements such as rain, snow, and excessive heat or cold.
  • Do not sit on or stack any materials on top that could crush protective shipping cartons as this may cause damage to the product.
  • Do not open shipping carton or remove ceiling tiles until ready to install.


General Characteristics

General tolerances & dimensions stability

– Up to 2” – tolerances of +/- 2 MM = +/- 0.08”
– Above 2” – tolerances of +/- 3 MM = +/-1/8”

Length & width:
– Up to 24” tolerance of +/- 3 MM = 1/8”
– Up to 96” tolerance of +/- 6 MM = 1/4”

Sonex convolution (sonex one / valueline / classic / mini / junior):
– Pattern alignment to edge: +/-1”

Due to the nature of willtec material, temperature and humidity may cause dimensional changes of up to 4% by volume.
