KVH or BSH — how to choose?
KVH C24 (Konstruktionsvollholz) is finger-jointed solid timber kiln-dried to below 18 % moisture content, planed on all four faces and machined to exact dimensions. It is the standard choice for timber framing, floor joisting, rafters and conventional load-bearing structures.
BSH GL24 (Brettschichtholz, glued laminated timber) is made by bonding spruce laminations with the grain running parallel. It allows long spans and large sections (up to 24 × 40 cm) — ideal for exposed roof structures, portal frames, main beams and mezzanines.
RE2020 compliance and getting ready for RE2028
Since 2022, RE2020 has set a threshold for the Ic construction index that bio-based materials make it possible to meet. RE2028, which applies from 1st January 2026 to new housing and offices, lowers that threshold to 6.5 kg CO₂/yr/m² for multi-unit housing (vs 8 in 2025).
To get ahead of RE2028, engineering consultants recommend 100 kg of bio-based materials per m². A roof structure built entirely from KVH/BSH spruce stores up to 1 tonne of CO₂ equivalent per m³ — a major low-carbon lever.
Our certified solid spruce range
The 62 BSH GL184 product lines cover sections from 6×12 to 24×40 cm (S4S profile, visible Si grade). The 63 KVH C184 product lines cover the common sections from 6×10 to 12×16 cm in NSI or Si grade.
Every piece we supply is Scandinavian spruce, PEFC-certifiable on request, with mandatory CE marking.

KVH C24 = finger-jointed solid timber in a single piece (strength class C24, 1-2 joints maximum). BSH GL24 = glulam made up of several laminations (class GL24h). BSH allows larger sections and greater lengths and takes higher loads over long spans.
Yes — it is one of the main levers for meeting the RE2020 carbon thresholds and getting ahead of RE2028 (1st January 2026, Ic 6.5 kg CO₂/yr/m²). Timber framing stores biogenic carbon throughout its service life.
NSI (non-visible): standard industrial quality, ideal for concealed framing. Si (visible): appearance-graded for exposed roof structures, mezzanines and frames left bare.
It depends on the span and the load. As a guide (Eurocode 5, residential load 150 kg/m², 60 cm centres): 6×12 cm for 2.5 m, 6×16 cm for 3.5 m, 8×16 cm for 4 m. Ask your structural engineer for a calculation.
Yes, on request our BSH and KVH products can be supplied with a PEFC chain-of-custody certificate. Scandinavian spruce comes mainly from sustainably managed forests. The PEFC label guarantees at least 70 % of material from certified forests.
