Mumford & Wood Heritage™ Range

Casement Windows


Here you will find our range of timber options for our Heritage™ Range timber Casement Windows. All species of timber used at Mumford & Wood is FSC certified.

As Standard

Siberian Larch

Siberian Larch:

Engineered Siberian Larch is used for the construction of the frame and sashes. Siberian Larch is classified as a softwood but (like quality hardwood) is naturally durable and does not require any preservative treatment. Siberian Larch is very slow growing and the consequence of this is very tight growth rings. The closeness of the annual growth rings result in a very dense and durable material making it ideal for the testing climatic conditions in the UK. All the Larch sections used are made up of engineered clear grade knot free timber for extra strength and durability.

Sapele wood


A solid section of Sapele which is an African Hardwood is used for all of our window and door cills. Sapele is very hard, durable and has a great strength. This makes it an ideal choice of timber to use for the most exposed part of the product.

Alternative Options (for whole frame construction)

Red Grandis

Red Grandis:

A high-grade naturally durable Hardwood timber, Engineered Red Grandis can be selected as a total construction alternative option on request. Red Grandis is used as our standard timber for stained finished products.

No items found.


Sapele is a very hard, dense and stable African Hardwood. As another alternative Hardwood option we can supply all of our products in engineered knot free Sapele on request.

Accoya timber


Accoya can be used for the whole frame construction on request. Recognised for its dimensional stability in extreme weather conditions we recommend the use of Accoya for products situated in coastal areas.
