Thermal downdraught on windows is a fact of life. I understand the mechanics involved, but that doesn't make it any more comfortable!
Short of replacing the glass in my double-glazed units with (yet) more efficient glass, what options do I have for reducing the uncomfortable effect of thermal downdraught?
If it is relevant:
- my uPvc double glazing is all black (internal and external)
- All windows have roller blinds, some also have curtains
