What is timber frame?
In simple terms, a timber frame building uses timber studs within the external structural wall to carry the loads imposed before transmitting them to the foundations. Timber frame buildings include the walls, floors and roofs, which are designed as a whole, coherent engineered structure.
What is timber frame construction?
With timber frame construction being a lightweight structure, there are elements to consider when agreeing the specification with your architect to make sure you are as satisfied as you can be when living in the finished property.

What is the requirement for fire resistance in a timber frame wall?
A half hour fire resistance in domestic external walls is required by the Building Regulations. Timber frame walls filled with mineral wool insulation are ideal for meeting this requirement. In most timber frame constructions, cavity barriers must be used to divide up the external cavity in order to reduce the risk of fire spread.
Is timber frame insulation good?
Insulated external timber frame walls can provide better insulation performance than masonry walls of comparable thickness. Timber frame is also widely recognised as the most environmentally friendly construction method – a construction with extremely low ‘embodied energy’.
Structural Insulated Panels (SIPs)
Structural insulated panels, or SIPs, have been around since the 1970s and have been growing in popularity ever since. In basic terms, SIPS are made from a ½-inch layer of oriented strand board (OSB), a layer of foam, which varies in thickness depending on your insulation needs, and another layer of ½-inch-thick OSB.
Conventional Framing
Conventional framing mimics the system used in standard construction (the way that most of the homes in the United States are built) and consists of 2-by-4-inch and 2-by-6-inch pieces of lumber for the wall framing and 2-by-8-inch, 2-by-10-inch, 2-by-12-inch or premade roof trusses to create the roof.
