AS Lasita Aken produced its windows and doors mainly from pine (it is possible to choose from finger jointed or solid pine) but also from premium timber such as oak and meranti.

All of the timber used is bought from reliable partners whose products have certificates of compliances and necessary documents. The timber goes through multiple quality checks and all non-complying material is removed from production.

For increased stability, the scantlings are glued together from three or four lamellas and in principle are faultless from all sides. Raw material passes double quality inspection: primary inspection at intake of materials (visual inspection of moisture content and conformity) and secondary inspection at selection of materials prior production. The material is chosen based on moisture content, bending and wood defects and if possible materials with similar structures and colour shades are used together.

PINE (Type: Scots Pine; Pinus sylvestris – Latin) Air dry density 480-530 kg/m3. Most used tree species. Timber is with average strength, measure stable to humidity and is not impact resistant. For the solid material, the exterior lamellas have unified structure and tone throughout the lamella. For finger jointed material, differences in in structure and tone may occur.
MERANTI (Type: Shorea SPP – Latin) Air dry density 580-770 kg/m3 The colour of unprocessed timber is from dark red-brown to lilac-brownish. Measure stable to humidity. Until three meters, solid, without finger joints material is used. Where possible, a batch contains materials with similar shades but differences may occur. To eliminate this, darker tones a recommended where differences are not seen.
OAK (Type: White oak, Quercus alba – Latin) Air dry density 690-700 kg/m3 The timber is hard yet flexible with good strength properties. Very resistant to decomposition and extremely resistant to wood diseases. Solid material is used up to 4000mm. For longer details finger joints are used.
