Wall underlay plays an important role in the weathertightness of exterior wall assemblies in light timber-framed residential buildings, yet often it is poorly installed. Getting it right can be as simple as 1, 2, 3.
A waterproof coating is essential to maintain the weathertightness of single skin concrete block walls since concrete masonry, and particularly the mortar joints, have little resistance to water penetration.
Here’s a simple way to make your ridge junctions neat and tidy.
The last year has been an interesting one for market share of building materials as changing preferences and availability issues due to supply chain constraints influence market share.
At BRANZ, we often get asked if it’s necessary to have a lintel over an opening in a wall under a gable end where the gable framing may be able to span the opening without support from the lintel. Here’s our advice.
More complex building designs may include wings with shared walls that have extra considerations for bracing demand.
Here, we use drawings to explain the specific parameters for the location of loadbearing or braced walls for suspended timber floors.
The weather’s not good but the job needs finishing. Is it worth the builder taking a risk and using a flexible wall underlay as temporary weather protection to carry on with work that needs to be kept dry? BRANZ has no doubt that the answer is no.
Wall design will play a key role in the improved thermal performance of new houses as we move toward net-zero carbon construction. One recent research project found problems with current wall construction, but another developed high-performance details that take us a leap ahead.
