Thermo Pine as a decking board

The accessible Thermowood deck — warm honey-brown boards, resin-free and dimensionally stable. For complete material data see the Thermo Pine master page.

Why it works as a deck

The everyday Thermowood deck

Thermo Pine on a deck trades the hardness of Ipe for approachable pricing and warmth. Thermal modification strips the resin that natural pine would weep in sun, closes the cell wall so the boards swell less with rain, and gives a honey-brown finish that silvers evenly if left raw. For residential verandahs, villas and rooftop terraces it is the Thermowood deck that stays within budget.

Positioning note: Thermo Pine suits sheltered-to-moderate exterior exposure in residential settings. For pool decks, resort boardwalks or heavy commercial foot traffic, consider Ipe or Thermo Ash instead.

Installation

Decked, not just panelled

Joists & sub-structureTreated hardwood or steel joists at 400mm centres (300mm for diagonal lays). Keep boards 150mm clear of soil and standing water.
FixingsStainless A2 or A4 only; galvanised fasteners stain thermally modified timber. Hidden clip systems give the cleaner finish; pre-drill before face-fixing to avoid end-splitting.
Board spacing5–7mm gaps between boards for drainage and airflow.
Finish & weatheringLeft raw, Thermo Pine silvers to a soft grey within 12 months. To hold the honey tone, apply a UV-pigmented penetrating decking oil at install and once a year thereafter.
VentilationOpen underside, at least 50mm of airflow between board and substrate. A sealed deck will trap moisture.
