Timber frame construction

Megapan boards are extremely suitable for boarding timber framed constructions. Several layers of boards can be installed per side according to the demands for noise insulation and fire-resistance. The boards are fixed to the wooden construction with staples or nails. High-speed building screws can also be used. The boards are always placed in such a way that the butt joints are positioned opposite each other on the same post. Vertical joints without a timber support are not allowed in single layered constructions. When installing multiple layers, every other layer is fixed with a staggered joint (minimum 20cm).
Megapan boards are usually mounted vertically onto the timber frame.

Horizontal joints should be avoided. If this is impossible, horizontal joints must stagger (minimum 20cm). Cross joints are not allowed!

Framed Constructions

Non Load-bearing Constructions: Here the timber frame needs to be suitable for timber construction. The standard of quality must meet the regulations in force.
The timber frame must not warp when stapling or nailing down and should have a minimum bearing surface of 25mm.

The centre distance of the wooden posts depends on the thickness of the boards.

Thickness boards	10mm	12mm	15mm	18mm
Max distance ( mm )	500	600	750	900

Load-bearing Constructions:  In this case the walls bear their own weight but also carry the vertical load downwards. Per construction, the timber frame must meet the general basic demands as well as the demands for the reliability and usefulness of the construction. It must also meet the demands of pressure and distortion as well as the standards of timber frames and fixings.

For bearing constructions the minimum thickness of the boards amounts to 12mm. Vertical and horizontal (preferably avoided) joints are always filled with joint glue. The centre distance of the wooden posts depends on the thickness of the boards and as long as fixings, joint techniques, edge distances, etc….do not require specific distances, distances below can be applied.

Thickness boards	12mm	15mm	18mm
Max distance ( mm )	600	600-750	600-900

Fixing

The megapan boards can be fixed with staples or nails. This goes for load-bearing as well as for non load-bearing walls.  It is advised to use a pneumatic stapler or a pneumatic nail gun.

The pressure should be regulated so that the fixing countersinks 1-2mm. In case of non load-bearing walls, boards can also be screwed down using high-speed building screws fit for this purpose.

Non load-bearing constructions:

Staples (galvanised and resin-coated) d = min 1,5mm

Nails (galvanised and resin-coated) d = min 2,2mm

High-speed building screws d = 3,9mm

Load-bearing constructions: the distance between the fixings mount up to 150mm on the middle joists and 75mm on the side joists. (See drawing)
