More than meets the eye: what’s happening behind your stucco and manufactured stone
New this year, Dörken has just released DELTA®-DRY & LATH to help builders protect their stucco and manufactured stone homes. The DELTA®-DRY & LATH system leverages the proven technology of DELTA®-DRY, the first channeled polyethylene sheeting that dries and drains, and that can’t be penetrated by moisture, neither liquid nor vapor.
High-performing Air Barriers: The Unsung Hero of Construction
A good air barrier provides a separation between controlled indoor air and uncontrolled outdoor air. When used in combination with a good thermal barrier, a well-constructed air barrier will keep the occupants’ space at a more constant temperature without excessive air conditioning or heating. This reduces occupant and building utility costs as well as costs of maintaining heating and cooling equipment.
Five factors that contribute to moisture-related issues in basements
Today, people think about basements a little bit differently than in the past. While the idea of turning a basement into a livable and comfortable space seems like a necessity, it used to be the opposite. In the past, basements were merely used for storage purposes or were simply left unfinished. Now, the expectation among residents in general is that these spaces should be comfortable, meaning mold free and problem free.

Managing leaky basements without digging yourself into a hole - DELTA® ACADEMY %
Basement leaks can either be slow and steady, gradually seeping into a dwelling over days, weeks, and months, or they can be fast and furious, bursting through walls unannounced to create a new and unwanted indoor pool. Either way, when left untreated, that unwanted moisture can cause major issues when it comes to homeowner comfort and health, and can lead to some serious structural concerns.
Sheathing Membranes – Important Characteristics and Codes
Sheathing membranes typically consist of thin sheet materials placed on the exterior side of the sheathing board in exterior wall assemblies. The function of the membranes is to resist the transfer of water and sometimes air (depending on the properties and need) while also allowing for water vapor diffusion (i.e., outward drying) in most scenarios. A number of materials may serve these functions and selection can be complicated.
Sheathing Membranes: Air Barrier Building Code Requirements - Delta Insights
Sheathing membranes that act as air barriers are typically of the polymeric type, and can be separated into two categories: mechanically fastened and self-adhered. This article will help familiarize you with the North American building code requirements and testing standards in relation to air barrier sheathing membranes.
A Builder’s First Time Using Peel and Stick House Wrap
When maintaining long-term building integrity, airtightness is an important feature to keep in mind. Airtightness simply means that there are no unintended gaps in the building envelope—gaps that would otherwise cause air leakage in or out of the building. It is an essential performance parameter in helping ensure energy efficiency. How airtightness is achieved comes down to the specifications of the air barrier used throughout the build. More here!
