W W hen it comes to the wine business, the harvest is considered the most crucial time of year. And once the grapes are harvested and the wine-making process begins, having a functional cold storage facility is vital. Unfortunately for Realm Cellars out of Napa County, their chilled storage facility was rendered unusable due to the poor application of spray polyurethane foam (SPF) and intumescent coating on the ceiling directly under the roof and walls. Realm Cellars vineyards stretch from the Silverado Trail to the top of Wappo Hill in the Stags Leap District. e grapes from the vineyards are processed and stored in modern wine cellars with top-notch equipment, and the resulting wines are highly sought after, with many vintages selling out within a few hours of release. With the main storage facility out of commission, the Realm Cellars label was in jeopardy. ey had only weeks to go before the harvest, so Realm turned to Wedge Roofing for help. Rise in Popularity According to Gary Harvey of Wedge Roofing, the initial specifi- cation for the SPF application on the storage facility ceiling and walls seemed simple enough: Install 2 inches (5.1 cm) of SPF over the wood framing, and then coat the SPF with an intumes- cent thermal barrier. "e finished surface was specified to be a 'smooth, cleanable surface in compliance with incidental food contact cleaning procedures.' However, this is not what we found," explained Harvey. It seems that the previous applicators were ill-prepared to apply SPF according to the specifications — a situation that, according to Harvey, happens all too often as the popularity of SPF rises. T he application of SPF, also called spray foam, has become more and more common in both the residential and commer- cial markets. W hile this is wonderful news for home and business ow ners looking for energ y efficiency, it also means that many inexperienced contractors are rushing to utilize the product for their clients. It is important to remember that spray ing SPF is both a science and an art; it takes time, experi- ence, and skill to properly apply SPF, especially on complex and time-sensitive jobs. A 9-person crew from Wedge Roofing applied a coating system to the storage facility at a Napa winery. All 7,000 square feet (650.3 m²) was completed in 12 days and around occupied office space.
