Use of vapor retarders to reduce moisture covered in new e-book

What is a “moisture sandwich”? In a new e-book from The Construction Specifier, Ted Winslow of CertainTeed Insulation explains how tight-envelope construction techniques have led to a steep reduction in air movement through walls. This means moisture gets trapped inside wall cavities without sufficient means for it to escape, leading to reduced drying potential for a wall’s interior. This “moisture sandwich” is occurring with increasing frequency as architects incorporate … Continue reading Use of vapor retarders to reduce moisture covered in new e-book

Questions about heat, air, and moisture control? Check out the new e-book

Many designers and specifiers understand controlling air, vapor, and thermal transfer helps mitigate moisture problems within the building envelope. Moisture accumulation is a performance adversary that can lead to structural deterioration, finish damage, organic growth, and reduced building longevity. However, navigating the fundamentals, code requirements, and industry trends can be complex.

As codes advance and higher performance is expected from building assemblies, the control of moisture within and through the exterior envelope is critical to … Continue reading Questions about heat, air, and moisture control? Check out the new e-book

Put penetrations to the test: The effect of cladding attachments on air and water barriers

Guidelines for detailing and testing air and water barriers (AWB) with cladding attachments are limited, and installation practices are not consistent across projects. Each of these penetrations have their own unique attachment method, with varying potential effects on air and water tightness and the building’s overall thermal performance. However, the impact these cladding attachments may have on the effectiveness of the AWB can easily be overlooked.
