Rubb buildings support energy efficiency

Rubb’s white translucent PVC cladding allows natural light to illuminate the interior of our buildings, while reducing the heat island effect on the structure.


The picture below is an external view of a Rubb fabric building used in some recent infrared tests. It is a 70ft x 80ft x 16.4ft BVE type structure, used as a salt storage shed for the City of Sanford, ME. It was built in 2009 and has performed well for the public works department.


Thermal images were taken on a sunny spring day, where the sun was hitting the wall and roof at approximately the same angle. Results show that the reflective but translucent white roof is 12°f cooler than the sandstone-colored sidewalls.

The image below illustrates the results of the infrared surface temperature tests on the structure – a typical Rubb storage facility.


The outcome: a cool and comfortable indoor temperature while avoiding any need for lighting power consumption during a regular working day. These double energy savings help greatly reduce the Rubb structure’s operating costs.

Independent building science consultant Lew Harriman also notes: “We measured the air tightness of this building using a blower door. When its rolling overhead door is closed, it meets and exceeds the U.S. Army’s air tightness requirement to leak less than 0.25 cfm at a pressure difference of 75 Pascals (0.3” W.C). That means the building won’t have uncomfortable drafts, even in the highest winter winds. It also means its air tightness is better than half of the very air tight commercial buildings measured for ASHRAE’s recent research project RP-1478. When any building must be heated, that level of air tightness means big energy cost savings for every year of that building’s long life.”

This is just another advantage of choosing a Rubb building. For more information about Rubb building solutions visit us at or call 207-324-2877.


Bulk Storage and Salt Facility

Hissong Development Corporation, part of the Hissong Group of companies of hissong2_largeKennebunk, Maine, recently erected a Rubb structure at their bulk storage facility in South Portland, Maine as part of a commercial salt bagging operation. The BVE structure measures 100′ wide by 283′ in length with a sidewall height of 10, it sits atop an 8′ tall poured in place concrete wall.

The Rubb team worked closely with Hissong Development to design a foundation that would support the building and also allow for proper material flow inside the structure. With (2) opposing Cookson overhead doors in each gable end, vehicle movement is streamlined along one side of the building allowing loaders to move the salt to the bagging operation which is cordoned off via a concrete stem wall.

Chris Pizey, President of Hissong Development, says the decision to purchase a Rubb structure was an easy one. “The folks at Rubb are known for producing high quality products…just look across the Fore River at the Sprague Terminal. Those buildings have been there for years in a high use / high abuse environment and have held up extremely well. The folks at Rubb made the buying process easy and their engineers coordinated effectively with our foundation contractor. I would highly recommend this product and company if you need a rugged and reliable storage solution.”

The Hissong building is Rubb USA’s latest project and is located less than a mile from Rubb’s first commercial structure erected in 1984 at the former Merrill Marine Terminal (now owned by Sprague Energy) on the Portland waterfront. Affectionately referred to at Rubb #1, this structure has stood the test of time for 30-years and proudly wears its original PVC membrane. Clearly Rubb sets the bar when it comes to product quality, safety and longevity.
