When Zack Polanski blogs about how UK homes are poorly insulated I get frightened. A lifelong asthmatic, the thought of living in a #GreenParty airless thermos flask fills me with horror.

I don't trust the Greens to do anything pragmatic - If you can't breathe - get on your bike etc. etc. Better you die choking rather than the planet

@thanetric There has been a lot of good work done on air quality in recent years.
Preventing draughts can reduce the entry of pollution from the outside air, including particulates and NOx, both of which can trigger asthma. And insulation, done properly, can reduce the cold spots that may harbour damp and lead to allergenic spores.

What matters more to me is the freedom to open a window when I want to, enough air exchange to keep CO2 down to sane levels, and humidity in a narrow band neither too dry, nor too wet.
