Earlier we mentioned wooden frames generally fall into the category of hardwoods or softwoods.
Hardwood is made of a structure which blends four different types of cell. For that reason, it’s very strong and hard-wearing. The blend of the wood also delivers that beautiful grain structure. Hardwood requires the most work in preparation and shaping before it’s ready to install.
Softwood is less dense and is comprised of two cell types. It’s much easier to manipulate and softwood is more common so it’s more environmentally sustainable. Softwood also delivers better thermal performance than hardwood frames.
Some woods commonly used are:
- Sapele – Hardwood
- Oak – Hardwood
- Redwood – Softwood
- Accoya – Softwood
