Spray Foam Insulation Lloydminster

Lloydminster is the only city in Canada built across a provincial boundary, and it runs on heavy oil. For a place its size it carries an unusual amount of working building stock - shops, service buildings, yards and industrial space - alongside ordinary residential streets. Spray foam gets used heavily here, and mostly for a reason that has nothing to do with heating bills. Spray foam insulation in Lloydminster is dominated by the shops and service buildings rather than the houses, and for a reason that is not heating cost.

Sweating steel is the local problem

Ask around and the complaint is consistent: water dripping off the inside of a shop roof through the winter. It reads like a leak and it is not one. Warm, moist interior air rises, meets a cold steel panel, and condenses there. Insulation hung inside the shell does not stop it, because the air still reaches the metal. Closed-cell foam sprayed directly onto the panel bonds to it and removes the cold surface from the equation entirely. That is why the material is specified on almost every heated shop in this area rather than chosen on price.

Houses get the same physics, different assemblies

In a house the equivalent problems are the rim joist, the attic ceiling plane and the crawl space - places where air moves freely and carries moisture with it. Sealing those is cheaper than most people expect because the areas are small, and it changes how the building feels within a day. Adding depth to an attic that has never been air-sealed is spending money on the second problem while the first is untouched.

Which product goes where

Closed-cell at roughly 2 lb runs R-6 to R-7 per inch, resists moisture and becomes a vapour retarder at about 38 mm under Alberta section 9.25 - it is the answer below grade, on exposed assemblies and on any metal building. Open-cell at roughly half a pound runs R-3.5 to R-3.8, is vapour-permeable and belongs on interior surfaces only, where it is cheaper and better at absorbing sound. Getting that split right is most of what separates a good quote from an expensive one.

Working across a border

Building requirements are set by the jurisdiction the structure stands in, so on a property near the boundary it is worth being explicit about which side the work is on before the specification is fixed. It rarely changes the physics and it can change the paperwork.

Code, either side

Foam facing occupied space needs a thermal barrier over it - 12.7 mm drywall or an approved intumescent coating - with an ignition barrier permitted where access is for service only. Medium-density material is governed by CAN/ULC-S705.1 and installation by CAN/ULC-S705.2.
