Metal building spray foam insulation in Beaumont is work on the steel buildings in the light industrial area on the edge of town, most of which went up in the last twenty years and are therefore not the neglected shells this kind of page usually describes.
A new steel building condenses just as readily as an old one
This is the point owners here are most surprised by. Age has nothing to do with the mechanism. Steel has almost no capacity to hold heat, so the inside face of the sheet sits at close to outside temperature whatever year the building was erected, and any moisture in the air inside will form on it. A twenty-year-old building with blanket in it and a fifty-year-old building with nothing in it arrive at the same place by slightly different routes. What the newer building has is a better starting condition to work with, not immunity.
What the builder's blanket is doing by year fifteen
Nearly all of these were erected with fibreglass blanket laid over the purlins and wrapped in a facing, which is a perfectly reasonable specification when it is new. It has a service life. The facing splits at the laps, the blanket compresses permanently where it crosses each purlin, and gravity does the rest, so somewhere between ten and twenty years the assembly stops being continuous. From that point the warm interior air has a direct route to the cold sheet and the building starts dripping. It is a predictable end of life rather than a defect, and it is roughly where this stock now is.
The bay that was finished and the ones that were not
Most of these buildings were bought as a shell and fitted out progressively, so a single structure frequently contains one bay lined and heated, one used cold for storage, and one that was never touched. Those are three different envelope conditions inside one roof and the boundaries between them are usually a stud wall with nothing sealed at the top. Treating this as one building produces a quote nobody wants. Treating it as the parts it actually has, and building the boundaries between them properly, is both cheaper and the thing that makes the heated part work.
What has to cover the foam, and where that line falls
Where a Beaumont building is a space people occupy, the foam takes a thermal barrier over it, and on a part-fitted building the interesting question is where that requirement stops. The lined heated bay clearly needs it. A cold storage bay nobody works in is a different case. That boundary gets established on the visit and priced from the start, because it moves with how the building is used rather than with its dimensions. More on thermal barrier vs ignition barrier.
Metal Building Spray Foam Insulation Beaumont: Common Questions
Why is a building that is not old dripping? Age is not the mechanism. The blanket has reached the end of its life, which is normal.
Do we have to do the whole building? No, and on a part-fitted building you should not. The boundaries between bays are the real work.
What does the covering apply to? The parts people occupy. Where that line falls gets settled on the visit.
