We investigate the hygrothermal performance of a brick veneer wall assembly with two different weather-resistant barrier (WRB) strategies – an innovative 3D dual ventilated sheet and a spunbonded polyolefin-based material.
Resource Type: Research Paper
This paper compares two types of wood-framed walls, one with an air gap membrane and another installed following standard practice, and the effects of inward vapor drives on each.
We explore if moisture problems in wood- or steel-framed walls are the result of inward solar vapor drives, and a lack of a drainage and ventilation space.
New polymeric WRBs with a range of vapor permeabilities are on the market. We examined the impact of various WRBs on their hygrothermal performance.
Can an HDPE drainboard meet the requirements of the Gotthard Railway Tunnels, including withstanding up to 45°C and an expected service life of 100 years?
Learn the essential advantages – and possible concerns – associated with the usage, durability, and design of HDPE dimple sheets and drainboards.
We explore a WRB’s essential functions, and durability concerns associated with polyolefin-based WRBs through our different testing methods.
This paper describes the advantages and concerns related to the using and designing with polymeric drainboards in tunnel construction.
We tested a polyolefin-based WRB and an innovative three-dimensional, dual-ventilated sheet to compare their hygrothermal performance in wall assemblies.
We studied the hygrothermal performance of a WRB and drainage membrane for residential and commercial construction. These were the results.
Learn about the performance of different WRBs with various vapor permeabilities, in varied climates and cladding applications, in wall assemblies.
