Building above grade is tough enough, but below grade? It is the most difficult space to get right. Not only does a basement hold the building up; it must keep groundwater, soil gas, and water vapor out, while keeping heat in during the winter and out during the summer.
Finally, a below-grade dimpled membrane that contributes to high-performance building compliance. Demonstrating market leadership in the growing movement towards product transparency and health in the built environment, DELTA®-MS is the first, and only, below-grade dimpled membrane to obtain a Red List Free Declare label with the Living Building Challenge (LBC) International Living Future […]
Managing moisture in a basement is difficult. We break down and detail the fundamentals of a water-managed basement foundation done right.
When it comes to below-grade moisture protection, cold weather and snow limit the use of any fluid-applied application. This can be avoided by selecting a better below-grade wall waterproofing solution that is designed specifically with cold climates in mind.
One of the most reliable ways of keeping walls dry and allowing them to dry out if they do get wet, is to construct the wall with an outer shell – also known as a rainscreen. A rainscreen is defined as an assembly applied to an exterior wall which consists of, at minimum, an out […]
Dörken’s engineers took on the challenge of designing a better residential rainscreen cladding system – here’s what we came up with.
We compared the intrinsic value asphaltic felts, self-adhering membranes, and mechanically attached synthetic underlayments provide a roofing assembly.
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.
This paper explores the loss of physical properties of water-resistive membranes due to temporary UV exposure, and what WRBs require to perform long term.
NFPA 285 is a code-required fire safety test for exterior wall assemblies, but it can be confusing as to which building materials and designs need to comply with the testing standard.
Top building scientist Dr. John Straube dives into the science of rainscreen wall systems, and what they require above all else to be effective.
Basements can account for 20% of a home’s total heat loss. While there are countless steps you can take to make homes more energy efficient, starting from the ground up is the best approach.
In this webinar, you’ll learn reliable waterproofing methods for foundations and below-grade structures from building expert Dr. Straube.
Building knowledge expert Gord Cooke discusses why we need to set new expectations for basements and foundations, cost-effective solutions that can enhance safety and comfort, and the building science behind it.
Gord Cooke discusses how builders and contractors can build better basements, increase their margins, and sell even more finished basements.
In partnership with Construction Instruction, this one-hour webinar will discuss construction details for building exteriors, including water and air barrier material choices and details that separate successful stucco installations from those that are prone to premature failure.
Matt Risinger, Jake Bruton, and Adrian Wegner share their best water-management practices for foundations and below-grade structures, to protect homes from structural damage, and ensure homeowners health and comfort.
In this webinar, two of North America’s most influential building science experts go head-to-head and debate on the construction industry’s hottest topics.
