Keeping the rain out: good site practice for timber frame buildings

TRADA image

Research has demonstrated that leaving a party wall cavity clear allows it to act like a chimney, pulling warm air upwards towards a cold roof space, with colder air moving in behind it. This cycle of air movement affects the thermal performance of buildings that have party wall cavities, even though insulation is already present between studs (for acoustic performance). Changes to building regulations in recent years have aimed to reduce heat loss and energy use, resulting in many more timber frame party wall cavities being insulated.

Timber frame building: materials specificationnavigation-arrow

This Wood Information Sheet (WIS) outlines the materials normally specified for conventional timber frame buildings. Some variations will occur according to the structural design and detailing requirements of specific projects. Many of the components are also used in innovative forms of construction such as engineered stud and twin stud walls,...

Breather membranes for timber frame wallsnavigation-arrow

All timber frame walls are designed to 'breathe'. The term 'breathe' refers to the ability of a wall to allow water vapour to diffuse through the structure. This is an important consideration to the long term durability of the timber structure.

A breather membrane restricts the passage of...

Condensation control in dwellingsnavigation-arrow

Condensation in dwellings occurs when warm moist internal air comes into contact with cold inside surfaces, or with cold air or surfaces within the structure.

With improved thermal performance and air tightness in new and existing buildings, the risk of damage from condensation has increased. Most surface condensation...
