Commercial building insulation retrofit in St. Albert runs into something no other city on this site does. This settlement dates from 1861 and it takes that seriously, so a proportion of the buildings here carry heritage significance and a proportion of the rest sit in areas where appearance is governed. What can be changed is part of the brief rather than an afterthought.
What you are allowed to change is part of the brief
On a St. Albert building with heritage status or in a controlled area, the exterior is frequently not available to work on. That is not an obstacle so much as a constraint that decides the method: the work goes on the inside face, it has to be reversible in principle, and it cannot alter what the building looks like from the street. Establishing which category a building falls into comes before a specification, because it changes both the approach and what is worth proposing.
Insulating a solid wall from the inside
Older masonry and timber walls handle moisture by drying in both directions, and putting the wrong assembly against the inside face can stop that and trap water in the structure. It is entirely workable but it has to be thought through rather than standardised, and on a building that matters historically it is a legitimate reason to be conservative. Doing less, properly, is a better outcome than doing more and causing a problem that shows up in ten years.
Losing floor area, and saying so in advance
Any interior insulation takes room off the inside of the building, and in a small older commercial unit that is real trading space. The honest thing is to put the number in front of an owner before the work rather than after, because on a narrow unit it occasionally changes the decision. It is easy to calculate in advance and there is no good reason to leave it until somebody notices.
The rest of the stock is a much simpler job
Away from the older core most of the commercial stock here is from the last few decades: retail plazas, professional buildings and service units delivered as shells with a bare roof deck and an uninsulated exterior wall. Those have no complication at all. They were simply never finished, which is a cheaper and more straightforward problem than a heritage wall and it is where most of the actual work in this city is.
Commercial Building Insulation Retrofit St. Albert: Common Questions
Our building is heritage. Can anything be done? Usually yes, from the inside, without altering the exterior. What is permitted gets established first.
Is a solid wall different from a modern one? Substantially. It dries in both directions and the wrong assembly against it can trap water, so it is detailed rather than standardised.
Will we lose space? Some, and the number belongs in front of you before the work rather than after.
