Profiled Glued Laminated Timber (Glulam) is a structural material made from kiln-dried lamellas bonded with melamine-urea-formaldehyde (MUF) or polyurethane (PUR) adhesive. The profiled tongue-and-groove joint ensures tight fitting of wall layers without drafts. Minimal shrinkage of 1–2% means a house built from glued laminated timber does not require a long settling period before finishing. Cross-sections: 180×200, 200×240, 240×270 mm. Length up to 12 m. Three-layer or five-layer lamination. Each lamella is inspected for defects, eliminating knots and cracks on the face surface. Applications: house construction (prefabricated house kits), energy-efficient buildings, saunas, hotels, public facilities. Complies with GOST 20850-2014. Supplied as a ready-made house kit with corner joints and insulated corners. Advantages over solid timber: minimal shrinkage (1–2% vs 5–8% for solid), absence of cracks and warping, factory precision of dimensions (±1 mm), possibility of lengths up to 12 m without splicing. Thermal resistance of a 200 mm wall is R=1.33 m²·°C/W (meets standards for regions with winters down to −25°C). Export documentation: ETA (European Technical Assessment), CE marking, certificate of conformity. Packaging: transport packs, protective film. Shipping: long flatbed trailers, Open Top containers. Wood species: spruce (light, lightweight, less resin) and pine (stronger, pronounced grain). Cedar is a premium option with antibacterial properties. Finnish and German production standards ensure moisture control of each lamella.
