Frequently asked questions about the Impregnated sawn timber category
What is Impregnated sawn timber and what is it used for?
Impregnated sawn timber is specially treated wood that has been impregnated with protective chemicals to increase durability and resistance to moisture, fungi and insects; it’s used in construction and outdoor applications such as framing, decking supports and fencing where enhanced decay protection is required.
What sizes of impregnated sawn timber are available?
Available sizes in this category include planed boards and beams such as 18x95x3000, 21x95x6000, 45x45x3000 and larger profiles up to 45x195x6000; lengths range from about 1000 mm to 6000 mm depending on the item.
What's the difference between planed impregnated board and planed impregnated beam?
A planed impregnated board (e.g. 18x95, 21x95 mm) is a flat profile suited for cladding and decking, whereas a planed impregnated beam (e.g. 45x45, 45x145 mm) is a sturdier rectangular or square profile intended for load-bearing structures and posts.
What colours are available for impregnated sawn timber and does colour affect protection?
Common colours are green and brown (e.g. green 18x95x3000, brown 45x70x1000). Colour results from the preservative used and does not reduce protective performance; protection level depends on the treatment type rather than the shade.
What wood species are available in impregnated sawn timber — pine, spruce, oak, birch?
The category lists both softwoods (pine, spruce) and hardwoods (oak, birch). Most standard planed boards and beams are typically pine or spruce, while oak and birch are offered for specific hardwood products.
Can impregnated sawn timber be used outdoors without additional painting?
Impregnation provides basic protection against moisture and decay so it can be used outdoors without immediate painting; however for appearance and extra UV protection it’s recommended to apply a finish (paint or oil), especially on end grains and exposed surfaces.
Which profile should I choose for a house frame — 45x45 or 45x95 mm?
45x45 mm is suitable for light framing and studs with low loads; for load-bearing beams, joists and higher loads choose 45x95 mm or wider profiles (45x145/195 mm) depending on structural load calculations.
Is impregnated sawn timber suitable for ground contact, e.g. fence posts?
For ground contact you should use beams/profiles with deep impregnation and sturdier dimensions (e.g. 45x70, 45x95 mm). The category includes suitable beams (45x70x3000, 45x95x3600), but check the treatment depth for direct soil contact.
How should I cut and treat the end grains of impregnated sawn timber?
After cutting, treat end grains with an antiseptic or end-seal preservative to restore the protective layer. Applying a preservative to saw cuts prevents moisture ingress and preserves the timber’s durability.
How to choose between green and brown treatment for decking boards and facades?
Choose mainly by aesthetics and how it matches other finishes: green treatment is common for general construction elements, brown gives a warmer tone suited to decking and facades. Both offer comparable basic protection, so pick by desired appearance.
