Timber frame construction employs breathable membranes, insulation, and vapor control layers, without compromising their durability.
All the building regulation requirements like fire, acoustic, and thermal requirements are also incorporated into the timber frame design.
Working of Timber Frame Construction
A timber frame building includes:
- Engineered Walls
- Engineered Floors
- Engineered Roofs
Major Elements of a Timber Frame Construction
2. Non-load Bearing Walls
3. Separating walls
4. Intermediate Floors
5. Roof
6. Foundations
1. External Walls in Timber Frame
- Plasterboard lining
- Polyethylene vapor control layer (500 gauge)
- Structural timber frame ( 89 x 38 mm or 140 x 38 mm studding)
- Insulating quilt or bats fixed between the studs
- Sheathing boards
- Breather membrane
- Wall ties
- External skin - brickwork, render, tiles or weatherboarding

The studs for timber frame panels are usually spaced at 600 mm. Integral timber lintels are used to support openings in load-bearing panels. Additional studs are used to take point loads imposed by beams, girders, or any concentrated loads. To carry higher loads, the stud spacing can be reduced.
2. Non-Load Bearing Walls in Timber Frame
These walls are made of stud frames with a depth of usually 89 mm. Plasterboard batts are fixed between the studs to provide sound resistance.
The timber frame package provides all the internal partitions, and framing for cupboards, reducing the amount of site-required carpentry to a minimum.
3. Separating Walls
Separating walls are formed by having a clear cavity between independent panels, with multiple layers of insulation batts and plasterboards.
