Study: PermaBase boards save time and cost

PermaBase Cement Boards provide a solution to builders battling labor shortage.
At a time when the labor shortage is a key issue for many builders, National Gypsum said that its PermaBase Cement Board offers faster installation while offsetting material costs and expediting construction schedules.

National Gypsum pointed to a study that showed its PermaBase Cement Board drastically reduces time and installation cost while requiring less skilled workers and fewer labor hours per-square-foot.

Conducted by the National Association of Home Builders (NAHB) independent subsidiary, Home Innovation Research Labs, the study found that using PermaBase Cement Board as a substrate in exterior wall systems with modified veneer mortar reduces installation time of adhered stone veneer by 35% and total installed cost by 6%.

The study was conducted on behalf of National Gypsum – the parent company of the PermaBase brand – along with co-sponsors Laticrete and Eldorado Stone. During the study, 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 – were compared.

Stacked stone veneer was installed on each of two identical facades of Home Innovation's test house during the study.

"Time is money – and using PermaBase Cement Board as a substrate in exterior wall systems with modified mortar can reduce construction time, reduce total installed costs and increase system performance for exterior applications," said Tony Fuller, product manager for PermaBase at National Gypsum. "Given the construction industry's shortage of skilled labor, evolving building envelope requirements and related construction costs, this is good news for architects, builders, general contractors and their clients."
