i'm looking at MVHR
want to get that sorted before doing any meaningful insulation
What's your logic? Avoid disruption to new finishes?
I'm looking at the other way around, fabric first. (Thinking it might be some time between them, and MVHR doesn't work in a leaky house from an energy/comfort point of view.)

mostly because my partner's allergies are driving her nuts and MVHR (with the right filters) is supposed to great for that
but also because I'm worried if we do our insulation first then it will lead to a damper house
I don't really expect the HR part to do much for a few years until we get the house more airtight
i'm looking at MVHR (mechanical ventilation with heat recovery system) which we'll get professionally designed and do a mix of DIY and professional installation
want to get that sorted before doing any meaningful insulation
