Luna Arctic Sharp HF Specifications
Size
20 mm x 142 mm (1x6). Lengths: 3.6 m to 5.1 m (approx. 11'10" to 16'9").
Species
Nordic Spruce.
Class
LunaThermo-D.
Surface
Brushed, painted (pre-greyed finish).
Performance
Dimensionally stable and durable in all climates. Low maintenance when installed according to Lunawood instructions. The pre-greyed finish is designed to develop naturally over time.
Fastening System (Exact Recommendation)
- Fastener type: Self-drilling exterior screws suitable for the substructure (timber or aluminium)
- Material: Minimum AISI 304 / A2 stainless steel
- Screw length: Minimum 2x cladding thickness (for 20 mm cladding: ≥ 40 mm)
- Hidden Fixing (HF) placement: Use one fixing at each cladding/subframe intersection, installed from the hidden fixing groove
- Angle: Fixings should angle towards the centre of the board to properly seat the groove edge
- Pre-drilling: Pre-drill and countersink to reduce cracking (pilot diameter: 0.5Ø to 0.8Ø, where Ø = screw diameter). Pre-drilling is required when the fixing point is < 50 mm from the end of the board
- Finish: Fix to correct depth with screw heads flush to reduce splitting, staining, and moisture traps
Installation
Install on a properly designed ventilated facade/rainscreen assembly and follow Lunawood installation instructions.
