Frequently asked questions about the Construction timber category
Construction timber — what is it and what is it used for?
Construction timber is sawn and planed timber for framing, boarding, terraces and sauna products: beams, planed boards, cladding and impregnated pieces. Sizes range from 18x45 mm up to 50x100 mm with lengths to 6000 mm, suitable for load-bearing frames, joists and interior/exterior cladding.
How does impregnated sawn timber differ from regular timber?
Impregnated sawn timber is treated with preservatives to resist rot and insects, extending durability for outdoor use. We stock impregnated items in green and brown in common sizes like 18x45, 18x95, 45x45, 45x95 and 45x195 mm.
What sizes of beams and boards are available in the Construction timber category?
The range includes common sizes such as 18x45, 18x95, 18x120, 21x95, 21x120, 45x45, 45x70, 45x95, 45x145, 45x195 and 50x100 mm; lengths vary from about 1000 mm up to 6000 mm depending on the item.
Are there terrace boards in the range and which materials are recommended?
Yes — the category includes terrace boards such as 28x90 and impregnated terrace boards 28x95. For external terraces we recommend thermowood or impregnated boards around 28 mm thick for moisture and wear resistance.
What timber is suitable for saunas and are sauna products available?
Yes — the category offers sauna wood products like cladding and thermowood, including aspen cladding (vooder lepp 15x90 A-SORT). For saunas choose A-grade cladding with low resin content for comfort and durability.
What is the difference between planed and sawn (edged) boards in the category?
Planed boards have a smooth, finished surface and precise dimensions (e.g. planed 18x95), while sawn/edged boards retain saw marks and may need further finishing. For visible finishes and accurate joins choose planed material.
Which wood species are offered — are there softwoods, aspen or thermowood?
The range includes softwoods (pine/spruce), thermowood and deciduous cladding options such as thermo aspen (lavalaud) and aspen cladding (vooder lepp A-SORT). Each product page specifies species and grade.
How to choose a beam for load-bearing structures — what to check?
For load-bearing work choose beams from 45x95 mm or 50x100 mm, planed and properly dried with appropriate grade and moisture content per structural calculations. Check for preservative treatment for external use and avoid deep cracks or large knots.
Is construction timber compatible with internal and external cladding in this category?
Yes — planed beams and boards work for frames while internal/external cladding (15x90, 18x95 etc.) serves as decorative or façade finish. Choosing the correct thickness and profile ensures tight joints and proper ventilation.
What criteria to use when buying planed beams for a house frame?
Choose planed beams with accurate dimensions (e.g. 45x95, 45x145), low moisture content and minimal defects. Use impregnated beams for exterior frames and A/B grade for interior visible finishes.
