Study Finds Using PermaBase® Cement Board As Substrate In Exterior Wall Systems Reduces Installation Time And Total Installed Cost Of Adhered Stone Veneer
Side-by-Side Study Conducted by Home Innovation Research Labs™ Compares New Adhered Masonry Veneer System to Traditional Metal Lath-and-Scratch Method
CHARLOTTE, N.C., Jan. 8, 2019 /PRNewswire/ — A study conducted by the National Association of Home Builders (NAHB) independent subsidiary, Home Innovation Research Labs™, has found using PermaBase® Cement Board as a substrate in exterior wall systems with modified veneer mortar reduces installation time of adhered stone veneer by 35 percent and total installed cost by 6 percent.
Conducted on behalf of National Gypsum and co-sponsors Laticrete and Eldorado Stone the study compared the installation of two adhered masonry veneer systems – National Gypsum’s PermaBase® Cement Board with modified veneer mortar versus a traditional lath-and-cement mortar base. Stacked stone veneer was installed on each of two identical facades of Home Innovation’s test house during the study.
Using PermaBase Cement Board for stucco or stone façade applications saves time and money according to a study conducted by Home Innovation Research Labs, an independent subsidiary of the National Association of Home Builders.
