With a timber frame building and Expanded Polystyrene (EPS) walls we have to be thoughtful about how and where we are going to run the wires and mount the fixtures.  Our design includes dramatic lighting, fire and security alarms, audio and visual systems, a cash register and inventory system, wiring for the geothermal heating and cooling system, and the usual array of outlets and switches.

We called everyone together – Tom, Tom, Ed, Traves, Ryan from Delta H; Meggin from Bay State Audio; Evelyn from Evelyn Audet Lighting; Sam and Lenny from Century Electric – to discuss the challenges and develop a plan.

We decided to build two horizontal chases into all of the wall panels and run all of the wires for overhead and ceiling mounted alarms through the roof.   This will require close coordination as Delta H will leave off the roof sheathing until Century Electric and the alarm company run their wires on top of the foam insulation.

While we continue to work onsite – grading, compacting, and backfilling, we are also building components of the Charlestown Package Store offsite.  We are using Climate-Block, made by Delta H of North Kingston, RI, to cover the timberframe and for the entire structure of the wine storage room, beer cooler, and stair tower to the tasting loft.

Made of expanded polystyrene and engineered lumber the wall panels have an insulation value of R30 and the roof panels a value of R40.   And  there is no thermal bridging as the structural components do no extend from the outer surface of the panel to the inner surface.   The horizontal chase in the wall panel will allow us to run wiring for the electrical and alarm systems and similar chases will allow us to run the plumbing. The outer framing member of the roof panel extends 3/4″ past the foam and creates an air space under the roof sheathing to allow for ventilation and a cooler roof.

We have been working with Delta H for several months and are very excited to be pioneering the use of these highly energy efficient panels.   We will be posting an article about the Climate-Block and blogging about our experience using them.
