Roper is established south Edmonton industrial land, and the buildings there span several decades of construction practice. Before anything is specified, the useful question is which decade yours came from.
Three eras, three different jobs
Older buildings often have a bare deck or an original fibreglass blanket that has sagged, compressed at the purlins, and absorbed moisture. Insulating these means removing the failed system first - foam will not bond to damp, sagging fibreglass, and strip-out plus disposal is the line item most often missing from a low quote.
Middle-era buildings typically have insulation that meets the code of their day but no deliberate air sealing. They perform adequately on paper and leak at every joint, lap and penetration.
Newer buildings are generally well specified thermally, and the remaining problem is usually stratification in a tall volume plus door cycling.
One district, three answers. Nobody can price this from an address.
The operating-cost frame
For a commercial building the argument is not comfort, it is cost - and it has three parts worth separating:
Heat you are paying for and losing through the deck and the joints.
Heat you are paying for and never using - the stratified layer sitting at the top of a tall space that nobody works in.
Damage you are paying for without attributing it - condensation on cold steel dripping onto stock, racking and equipment, usually written off as a roof problem.
The third is frequently the largest and the least visible. See commercial spray foam ROI.
Multi-tenant considerations
Established industrial parks hold a lot of leased space. Envelope work on a unit you lease sits differently depending on the lease, and the split between landlord and tenant is worth settling before you get a quote rather than after.
If the deck runs continuously over several bays, insulating only your unit needs a deliberate detail at the demising walls - it works, but the boundary has to be designed rather than simply stopped.
Sustained cold, not swinging cold
Edmonton holds its cold. Heat loss is cumulative and proportional to how long the temperature difference lasts, so a leaky commercial envelope here is not paying a penalty during a few cold snaps - it is paying continuously for months. That shortens the payback relative to the same building in southern Alberta.
What we do
We are a referral service. We do not install. We connect you with vetted installers - certification, insurance and WCB standing checked - and they quote directly.
No price without a site visit. Get a quote, and tell us roughly when the building went up, what is overhead now, and whether you own or lease.
