Fiberglass Insulation
Spray foam is our specialism, but not every part of every building needs it. Where fiberglass is the sensible choice for an area, we will say so.

Where fiberglass still makes sense
Fiberglass is a mature, well understood product. In open framing with regular spacing, on an attic floor that stays outside the conditioned space, or in an area where budget genuinely decides the outcome, it can be the right answer.
It is also common to find a building where part of the work calls for foam and part does not. Mixed jobs are normal, and pretending otherwise would just cost you money.
Where it struggles
Fiberglass does not seal air movement. It slows heat transfer through the material, but air can still move around it through gaps, penetrations and anywhere the fit is not perfect. In an irregular retrofit, around wiring and plumbing, or anywhere moisture is part of the picture, that limitation is what drives people to foam.
It also does not handle water well. Wet fiberglass loses most of its value and holds the moisture against the assembly, which is why we so often remove it from crawl spaces and damp attics rather than replacing it like for like.
How we decide
The same way we decide everything else. We look at the assembly, how the space is used and what condition it is in. Then we tell you what fits, including when the honest answer is the cheaper product.
Fiberglass insulation FAQs
The things people usually want settled first.
Do you install fiberglass insulation?
We work with it where a building calls for it, usually alongside spray foam on the same job. Spray foam is our specialism and it is most of what we do.
Is fiberglass worse than spray foam?
It is different, and cheaper. The important difference is air sealing: fiberglass slows heat through the material but does not stop air moving around it. In an irregular retrofit or anywhere moisture is involved, that is what usually decides it.
Should I replace my fiberglass with spray foam?
Sometimes, and sometimes not. If the existing material is dry, clean and simply thin, adding to it can be perfectly sensible. If it is wet, contaminated or settled, it needs to come out whatever goes in next.
