Installation

Please follow the following instructions carefully:

Installation
  • Always store the boards in a dry place. Only install the boards if they are dry.
  • Always install the boards so the side with the marking is exposed on the exterior of the building.
  • Max. rafter distance (centre-to-centre):
  • Install the boards lengthwise with exact fit for tight joints.
  • Avoid walking on areas between the rafters.
  • Immediately install battens after installing boards.
  • Adhesive nail tapes or sealants are not required.
  • Avoid cross joints.
  • Do not use damaged boards.
  • As a rule, the boards install perpendicular to rafters.
  • Stagger butted side joints with the next row’s joint being centred no closer than the next rafter.
  • All seams and roof joints must be properly sealed with the GUTEX Joint Sealing Kit to prevent the ingression of rain, e.g.
  • Always install the boards so that their tongues point upwards.
  • The boards do not provide suitable structural support or stability.
  • GUTEX Multiplex-top is not a load-bearing structural element (e.g. snow)
  • Avoid exposure to high levels of moisture (e.g. wet screed) on the interior sides of the boards.
  • Vacuum off the dust in accordance with applicable workplace safety regulations or practices.
Excerpt from "Guidelines for Roofing with Tiles"
  • If the roof pitch does not exceed the minimum roof pitch and there are not more than three of the requirement-raising factors present, it is not necessary to tape the board joints.
  • If the roof pitch is 8 ° less that specified standard, and up to three of the requirement-raising factors are present, it is not necessary to tape the board joints.
  • If the roof pitch is 8 ° less that specified standard, a sub roof is required.
  • Factors that may raise requirements are: roof pitch, construction, use, climate and local regulations/conditions.
