What is a loft insulation top-up?

Before we quote we measure the existing layer in several places and check its condition. If it is dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Questions about a loft insulation top-up in Cheshire

Which council covers my address in Cheshire?

Councils in Cheshire include Cheshire East, Cheshire West and Chester, Halton and Warrington. Your council matters for building control questions and some funding schemes.

How do I book a survey in Cheshire?

Send the form or call us. We call back to agree a time and confirm it in writing.

Which way should the top-up layer run?

Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.

Can I still store things in the loft after a top-up?

Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
