Technical Data
Installation

Please follow the following instructions carefully:

Installation:
  • Store and install this product dry.
  • Install joint strips with marking facing upwards and the boards with their marking facing down.
  • Substrate must be dry, even and technically sound.
  • If required, install a moisture barrier.
  • Install the edge/perimeter stripping so that its top edge is flush with the top of the Thermosafe-nf board face.
  • Keep the distance between the ends of the joint strips and the walls at 20 mm unless otherwise specified by the flooring manufacturer. In addition, leave 1 - 3 mm space between the joint strips. (See drawing below.)
  • The joint strips are to be installed so that the joint between the joint strip in the next row is at least 1 metre away (in either direction) from the joint in the previous row.
  • The first and the last boards must be a minimum of 12 cm long.
  • On-centre distance between joint strips: = 41.4 cm
  • To cut the boards, use GUTEX saw blades for jigsaws or circular saws and a vacuum fitting.
  • Vacuum off the dust in accordance with applicable workplace safety regulations or practices.
  • If higher insulation built-up heights are required, use GUTEX Thermosafe-wd under GUTEX Thermosafe-nf (max. 100 mm).
  • The floor planking must be at least 19 mm thick.
  • Each  plank must be fastened at a minimum of two points.
  • GUTEX Thermosafe-nf must be installed with full surface contact. Avoid interruptions in the surface contact, i.e. due to plumbing or electrical installations, etc.
  • For flooring that is especially sensitive to moisture, such as beech, birch or black locust, we recommend using 2 system strips glued together (side by side) with white glue. Stagger the joints.
  • Install the boards so the joints are tight. Use the oddment of the last board of a row to start the next row (refer to layout plan).
