Loft insulation in Stirling

A modern trussed loft with the original pink insulation flattened and patchy after years of settling. A new layer of Knauf Earthwool across the whole loft, out to the eaves and up to the gable wall.

Trussed loft in Stirling topped up with Knauf Earthwool

What we found

A trussed roof with plywood sarking and a blockwork gable, and the original pink mineral wool lying between the ceiling ties. It had done its job for years, but it was thin, flattened in places and nowhere near the depth the loft needed.

You don't need to rip out old insulation that's dry and clean. You measure it, then add what's missing on top.

What we did

  1. Measure and check

    Existing depth checked across the loft, cables and fittings located, eaves ventilation checked clear.

  2. New layer over the old

    Knauf Earthwool rolled out over the existing insulation to bring the loft up to the depth it needed, laid tight with no gaps between rolls.

  3. Into the edges

    Pushed right out to the eaves without blocking the airflow, and tight up against the gable wall, where cold spots usually get left.

  4. Leave it usable

    Cables left on top where they can be found, fittings kept accessible, hatch area tidied.
