Can you board over loft insulation?
You can, but laying boards straight on the joists squashes the insulation. A raised floor avoids that.
The problem
Flattened insulation loses most of its warmth. Boarded lofts often hide thin, squashed insulation.
The fix
Legs on the joists and boards above, with full-depth insulation underneath.
