Drainage Balance Testing of Mineral Wool Insulation

Drainage Balance Testing of Mineral Wool Insulation

By: Jonathan Smegal. Abstract: Modern building enclosure designs often make use of rainscreen cladding and a layer of continuous insulation installed outboard of a drainage plane / water control layer. Although mineral wool insulation has been used successfully in rainscreen and masonry cavity walls for several decades, the relative unfamiliarity of the North American building […]

Moisture-Related Durability of Walls with Exterior Insulation in the Pacific Northwest

Moisture-Related Durability of Walls with Exterior Insulation in the Pacific Northwest

By: Jonathan Smegal, John Straube, Joseph Lstiburek, and Aaron Grin. Abstract: This paper compares the moisture-related performance of a wall with exterior insulation installed over oriented strand board (OSB) to the performance of a drained and ventilated wall with a 19 mm (0.75 in.) gap and a wall with direct-applied stucco over building paper. The […]
