Timber Development UK has issued a trade note on the subject, reassuring members that this does not indicate a shortage of timber available to the UK, but rather that the mix of species being imported is changing.

The UK construction industry heavily relies on coniferous timber, with about 65% of requirements being met through imports.

European Whitewood (Spruce) and European Redwood (Pine) are the dominant species; however, recent Bark Beetle infestations, geopolitical factors, and changing forest management priorities have led to some European sawmill lines temporarily closing.

TDUK chief executive Dave Hopkins said: “Spruce has traditionally been preferred for use in construction projects due to its visual appeal and smooth finish. However, market changes are causing us to see a higher proportion of Pine imports.

“Merchants and contractors must recognise that pine has the same strength grading as spruce. Although it may appear slightly different visually, it can be used for C16, C24, and TR26 applications in the same manner as Spruce without concern.

“Merchants can be confident that each piece of structural timber will meet the strength class performance stamped on it – whether it is pine or spruce.”

In fact, for garden and exterior products such as decking and cladding, pine is more readily able to absorb preservative treatments, allowing it to achieve Use Class 3 and Use Class 4 more easily than spruce, which requires incision for ground contact Use Class 4 applications.
