Hardwood Timber Specification

Wherever possible County Oak sources the timber used in the construction of our conservatories, orangeries and garden rooms from responsibly managed forests.  Selected sections are used for a combination of strength, durability, machining flexibility and an ability to accept a wide range of finishes.Using a matrix of sizes underwritten by our structural engineer every County Oak roof is designed to meet current British standards and underwritten by a structural engineer. Structural tie-bars are included where necessary and if building regulation approval is required full structural calculations can be supplied.
