|||
| Glulam strength class according to EN 14080 | GL30c | ||
The strength classes are designated by GL and a class, for example GL 30. GL stands for Glued Laminated Timber (Glulam) while the number 30 stands for characteristic bending strength, expressed in N/mm². The class is followed by a designation that describes whether the glulam element consists of homogeneous glulam lamellas "h" (homogenous) or combined glulam lamellas "c" (combined), for example GL 30h. In addition, the letter "s" (split) can be used to indicate that it is split-sawn glulam, for example GL 28cs. |
|||
| Profile type according to Swedish Wood specification | Straight glued laminated timber element with rectangular cross-section | ||
Wood can be processed into different profiles with different appearances and uses. For example, different forms of sawn, planed, grooved sides and edges. Or milled grooves and rebates for joining, and more. |
|||
| Surface structure according to Swedish Wood specification | Cleanly planed, unrepaired surfaces | ||
The different side and edge surface structures for a profile type can be produced to meet different technical and appearance requirements. For example, with different techniques and equipment for sawing, planing, grooving and grinding. |
|||
| Width of the glued laminated timber element according to EN 14080 | 115 mm | ||
The width of the glulam element is referred to as the unit of measurement "b" in descriptions of the cross-sectional dimensions. Dimensional tolerances for the unit of measurement "b" are +/- 2 mm according to SS-EN 14080.
Nominal dimensions at a reference moisture content of 12%. |
|||
| Height of the glued laminated timber element according to EN 14080 | 270 mm | ||
The height of the glulam element is referred to as the unit of measurement "h" in descriptions of the cross-sectional dimensions. Dimensional tolerances for the unit of measurement "h" are +4 mm to -2 mm where "h" is equal to or less than 400 mm. For "h" greater than 400 mm, the dimensional tolerances are +1% to -0.5, according to SS-EN 14080. Nominal dimensions at a reference moisture content of 12%. |
|||
| Total number of laminations according to EN 14080 | 6 | ||
A glulam element consists of a number of structural timber laminations. The total number of laminations is equal to the sum of the number of outer laminations and the number of inner laminations in the glulam product. |
|||
| Thickness per lamination according to EN 14080 | 45 mm | ||
The laminations thickness varies depending on the type of glulam element being manufactured. For example, the lamination thickness can be different for straight glulam elements and for curved glulam elements. |
|||
| Strength class of outer laminations according to EN 14080 | T22 | ||
The laminations in laminated timber either have the same strength class, which is called homogeneous laminated timber (h) or laminations with different strength classes can be used for the outer and inner laminations, which is called combined laminated timber (c). In combined laminated timber, the strongest laminated timber is placed as the outer laminations where the stresses are normally greatest. |
|||
| Number of outer laminations according to EN 14080 | 2 | ||
The number of outer laminations can vary depending on how the glued laminated timber element is constructed and whether it is a homogeneous or combined glued laminated timber. |
|||
| Strength class of inner laminations according to EN 14080 | T15 | ||
In the case of combined glued laminated timber, there are different strength classes for the outer and inner laminations. The inner laminations have a lower strength class than the outer laminations. |
|||
| Number of inner laminations according to EN 14080 | 4 | ||
The number of inner laminations may vary depending on the dimensions and strength requirements of the combined glulam element. |
|||
| Number of adhesive joints according to EN 14080 | 5 | ||
The number of adhesive joints varies with the total number of laminations. |
|||
| Adhesive class according to EN 14080 and EN 301 | Type I | ||
Glulam manufactured with Type I glue can be used regardless of the surrounding climate (climate classes 1 – 3 according to Eurocode 5) while the use of Type II glue is limited to structures that are protected from the weather (climate classes 1 and 2 according to Eurocode 5). |
|||
| Adhesive group according to EN 14080 | MUF (Melamin-Urea-Formalaldehyd) | ||
Nowadays, for environmental reasons, melamine-urea-formaldehyde glue ( colloquially MUF glue or melamine glue) is used almost exclusively, and is classified as Glue Class Type I. Melamine-glued joints are initially light in color but may take on a slightly darker shade over time. |
|||
| Formaldehyde emission class according to SS-EN 14080 | E1 | ||
Low levels of formaldehyde naturally occur in wood so wood products cannot therefore be completely free of formaldehyde.. However, it is possible to regulate the amount of formaldehyde used in the binders used in the manufacture of glued wood products. Emission class E1 means that the product may not emit more than 0.124 milligrams of formaldehyde per cubic meter of air. This is the mandatory requirement in Sweden. |
|||
| Profile area, taking into account design, according to Swedish Wood specification | 0,03105 m² | ||
Calculated on the actual profile of the wood product.
For example, the area of a tongue-and-groove profile needs to be calculated taking into account the tongue-and-groove design. |
|||
| Target moisture content according to EN 14298 | 16 % | ||
The concept of target moisture content describes the desired average moisture content when delivering a batch of wood. Read more Swedish Wood - Wood and moisture |
