Orangery timber 

What is the best timber to use in the manufacture of an orangery? 

Actually we do not simply use one timber for the manufacture of our orangeries.  We use various solid timbers and composite materials, each selected for a specific purpose: 


External frames, doors and windows are manufactured in iroko, a naturally very durable timber with a lifespan exceeding thirty years, even untreated. 

We have used iroko for the manufacture of our joinery for many years and have extensive experience in its use.  We have found that while it can be difficult to machine, it is one of the most stable materials in service. 


Tulipwood is used for the internal roof lantern parts and internal mouldings.  This is a very strong fine grained hardwood, perfect for the structural parts of a roof lantern.  This timber is not durable so it is only suitable for internal components.


External trim components 

Some of the external components of an orangery are small parts, mitred together, for example, capital blocks.  These are difficult to seal effectively and joints are prone to cracking, allowing moisture ingress. 

We have therefore introduced a number of composite, rot-proof materials which we can use instead of timber, yet can be machined, jointed and painted in the exactly the same way.


Capital blocks and fascia 

These are manufactured from Duropolymer®, a fully water-resistant, high density polymer blend.  These are mitred, jointed with a special glue and are filled and caulked during installation with a flexible and paintable MS polymer sealant.


Plant-on glazing bars

These are manufactured from composite foam board, a totally rot-proof and waterproof material that we machine and paint in the same way as solid timber.
