Office building spray foam insulation in Edmonton is shaped by the age of the stock. A great deal of this city's office space was built in an era when energy was cheap and the envelope was a secondary consideration, and those buildings are still fully leased and still being asked to perform.
An older core, built to a different expectation
Buildings from the sixties through the eighties were designed around mechanical systems that were expected to overcome whatever the envelope did. That approach works until energy costs matter or until tenants compare one building with another, and both of those now apply. The buildings are structurally sound; the assumption underneath them has changed, and the envelope is where the gap sits.
Early curtain wall and where it leaks
The curtain wall systems of that period rely on sealants and gaskets that have a service life, and around the frames the insulation is often minimal or has slumped. The result is a perimeter that performs far below what the glazing specification suggests, and complaints that concentrate along the outside wall and in the corners. The spandrel areas between floors are frequently the worst part and the least visible, because nobody sees behind them.
The plenum above the top floor
On many of these buildings the ceiling of the top floor is a plenum open to the roof structure, and it is treated as an interior space when it is functionally part of the envelope. Warm air collects there, and where the roof assembly above it is thin or interrupted the loss is continuous. It is one of the few places in an office building where a large uninterrupted area can be treated efficiently.
Tenant turnover is the opportunity
A floor between tenants is the only time an office building is genuinely accessible, and it is usually a short window. Where a lease is ending it is worth deciding in advance whether envelope work is going into that vacancy, because doing it then costs a fraction of doing it around occupants later. That is a planning decision rather than a construction one and it has to be made early.
Office Building Spray Foam Insulation Edmonton: Common Questions
Perimeter offices are cold and the system is balanced. What now? That points at the envelope, and in an older Edmonton building usually at the spandrel areas and the insulation around the curtain wall framing.
What is the plenum above the top floor? The space between the ceiling and the roof structure. It is often treated as interior when it is really part of the envelope, and it is one of the larger areas that can be treated at once.
When is the cheapest time to do it? Between tenants. A vacant floor is the only time the building is genuinely accessible.
