The profile at a glance

The DIAMANT profile belongs to the Dartank thermally modified pine cladding family. Every one of our references is made from Scandinavian pine thermally modified at 200 °C, with no chemicals at all. The wood fibre is modified right through — high dimensional stability, increased resistance to fungi and insects.

Ventilated installation — the essential rules

Fixed to vertical or horizontal battens, with a breather membrane compulsory behind and a ventilated air gap of at least 20 mm. Fixings in A2 stainless steel (A4 by the sea) — Torx screws with a reduced countersunk head, or concealed clips depending on the profile.

Compliant with the requirements of DTU 41.2 (the French standard for exterior timber cladding).

Natural silver-grey patina

Left untreated, thermally modified pine turns a natural silver-grey within 8 to 18 months — a look much sought after in contemporary architecture. With a saturating oil applied every 2 to 4 years, the original brown tone is preserved.

DIAMANT is a thermally modified pine cladding profile — a specific machining of the board (grooves, chamfer, spacing) that defines its architectural look and its fixing method. It belongs to the Dartank thermally modified pine cladding family, in modified use class 3.
An air gap of at least 20 to 25 mm between the breather membrane and the cladding. Essential for moisture to escape — without it the timber will rot, even thermally modified.
Not necessarily. Left untreated, thermally modified pine turns a natural silver-grey within 8 to 18 months — a look widely sought after in contemporary architecture. With a wood oil (every 2-4 years), the brown tone is preserved.
A2 stainless steel screws (standard façade) or A4 (seafront, saline environments). Reduced countersunk head with Torx drive; trade brands: SPAX Façade, Essve, RothoBlaas, PGB.
