A lot of the arch buildings on acreages around Airdrie are working premises rather than storage, and that usually means something has been built inside them: a mezzanine, an office, a parts room, a washroom. Quonset spray foam insulation in Airdrie has to answer to that, because a room inside an arch changes where the envelope belongs and it is the question most quotes skip.
A building inside a building has two envelopes
Once there is a heated office in the corner of an unheated arch, there are two separate decisions. Insulating the whole shell to hold the office warm means heating the entire volume to keep one small room comfortable. Insulating the office as its own box - its own walls, its own ceiling, sealed from the rest - costs a fraction of that and works better. Which one is right depends on whether the main space is going to be heated at all, and that is the first thing to settle.
The ceiling over the office is the surface that gets forgotten
If the office has an open top, or a ceiling that is nothing more than a grid, the heat rises straight out of it into the arch and the room never holds. That ceiling is doing the same job as an exterior roof and it needs treating like one. It is a small area and it is frequently the difference between a room that is usable in February and one that is not.
A mezzanine changes the air, not just the floor
Adding a mezzanine puts people and warm air up near the shell, where the steel is coldest and where condensation forms first. A building that dripped harmlessly onto a concrete floor now drips onto a workspace. That is worth knowing before the mezzanine goes in rather than after, because the roof deck is far easier to spray with nothing underneath it.
Sequence it while the arch is still empty
Anything structural that has to reach the steel - mezzanine posts, hangers, brackets, an office frame tied to the shell - is far easier to place before the foam goes on. A fastener driven through foam afterwards compresses it, breaks the air seal and creates a cold spot behind whatever was mounted. Deciding the interior layout first is what makes the envelope work rather than fight it.
The shape still rules the product
No stud bays, no flat planes. Batt has nothing to sit in and rigid board cannot follow the curve without leaving voids that condense out of sight. Foam bonds to the shell and takes its shape. It needs clean dry steel, and once anyone is working in there, foam is combustible and requires a covering over it.
Quonset Spray Foam Insulation Airdrie: Common Questions
We have an office in the corner - insulate the whole building or just the office? Usually just the office, treated as its own box including the ceiling over it. Heating a whole arch to warm one room is the expensive answer.
Why does our office never hold heat? Very often an open or grid ceiling. The heat rises out into the arch, and that surface has to be treated as if it were a roof.
We are adding a mezzanine - what should we do first? The roof deck, while there is nothing underneath it, and set any brackets that need to reach the steel before the foam goes on.
