Description

Exterior wall timber frame.

Features and benefits:

  • Compact and light.
  • Easy handling - carrier boards can be handled by one person.
  • Can be cut with a knife.
  • For mounting to the external side of an ordinary wall.
  • Carrier boards are fixed to profiles using Externa-Light wood screws (placed no more than 200 mm apart).
  • Reinforced with a fibre mesh with blue markings on the sides to help identify the correct position for overlapping the strips.
  • Top coat with a grading of at least 1.5 mm will help to minimize the risk of hair crack lines.

Joints must be staggered according to the normal drywall construction. Horizontal battens are necessary to fix the boards to the loadbearing wooden structure, and expansion joints are required at each floor level – consult manufacturer for details.

Battens must be sized dependent on the desired performance, the seismic zone and wind forces.

Applications:

To be used for external walls.

Consult manufacturer's literature to view step-by-step installation information, substrate preparation and application conditions.
