The Wood we use

At 2 B Construction UK Ltd we consider a number of key factors when deciding what timber to use for our doors and windows. They are:

Suitability – Is the project internal or external

Straightness of the grain – Straight grained timbers are more stable

Texture (fine or coarse) – The finer the grain, the easier to finish to a high standard

Sustainability – 2 B Construction UK Ltd only use sustainable timbers

CostPurchasing timber on the basis of cost is almost always a false economy

The quality of the timber we use and our joinery construction methods are of paramount importance to the lifespan of your windows and doors. We use the traditional mortice and tenon construction techniques, identical to those that were used throughout the Georgian and Victorian periods when North London homes were originally constructed.
