Doors & Windows Ranges

English Heritage Buildings offers two different joinery ranges – Penhurst and Darwell.

Penhurst Oak Range

The Penhurst Oak Range comprises a host of joinery options* made to an exceptionally-high specification, including semi storm-proof windows and friction stays.

Darwell Oak Range

Available in oak, softwood or Iroko, the Darwell Oak Range offers a complete range of joinery options including garage doors, single doors, bi-folds and windows.

Timber Specification


Softwood is renowned for its strength and versatility. It can be used across a broad range of internal and external applications, which is why the timber is particularly suitable for joinery. It is advised that the material is treated straight away and maintained throughout the duration of its life.


Iroko is an African hardwood, best known for its rich reddish brown tone. The close grain of the timber means it is less prone to warping and movement.

Penhurst Oak

The natural longevity of Penhurst Oak makes this a firm favourite amongst customers. This FSC-certified European Oak is a sustainable choice that will retain its good looks when treated.

Darwell Oak

Darwell Oak is a robust, aesthetically-pleasing material that oozes strength and stability. It is also FSC-certified for added peace of mind amongst environmentally-conscious customers.
