There is no single price for spray foam. The cost of a project is set by the foam type, the thickness the assembly needs, the area being covered, how hard that area is to reach, and what has to happen before spraying starts. Here is how each factor moves the number.
Read the guideOpen-cell and closed-cell foam are both sprayed polyurethane, but they behave differently enough that they are not interchangeable. The right one depends on the assembly you are insulating, not on which is generally "better".
Read the guideThese two options do not just differ in material — they change where the insulated boundary of your house sits. That decision affects ventilation, moisture and cost far more than the R-value on the label does.
Read the guideMost attic insulation does not need to be removed. Old fibreglass that is dry, clean and undisturbed can usually be topped up. Removal is for insulation that has been compromised — and for the times you need the attic floor clear to do the job properly.
Read the guideNo insulation type is best for every part of a house. The useful question is which material suits a particular assembly, in a climate that swings from humid summers to sustained winter cold. Here is how the common options compare, space by space.
Read the guideThese guides exist to answer the questions that come up before anyone is ready to book work. Three of them are comparisons: open-cell against closed-cell foam, blown-in against spray foam for an attic, and the three common materials side by side. One is about money — what actually drives spray foam cost — and one is about a decision people put off, whether old attic insulation needs to come out.
Each one links down to the service page it belongs to, so you can move from reading to hiring without going back through a menu. If you would rather start from the work itself, the services hub explains how to choose between spray foam, blown-in attic insulation, fibreglass batts and removal, with fireproofing and soundproofing handled as the separate disciplines they are.
Nothing in here quotes a price, a percentage saving or a fire rating, because those depend on a building nobody has looked at yet. What the guides do instead is explain the mechanism, so the quotes you receive — from us or from anyone else — are easier to judge. When reading has taken you as far as it can, ask us to assess the space, or read more about how we work first.
