Roof insulation the best 8 types — guide from Ecoaim, Scotland's renewable energy specialist.
The short answer
This is one of Ecoaim's archive insights articles — covering roof insulation the best 8 types. For the most up-to-date guidance on this topic, talk to one of our engineers directly on 03330 384 380.
Choosing between the eight is really a choice about where the heat is escaping and what your loft or flat roof can physically take. Our roof insulation installers survey the build-up before recommending a material, and the full roof insulation types comparison sets out U-values, depths and typical costs side by side.
Why this matters in Scotland
Scotland's renewable energy landscape moves quickly — grant rates change, tariff structures shift, technology gets cheaper. Our team tracks every relevant policy and product change.
If you're considering a renewable install in 2026, several things work in your favour: zero-rated VAT on qualifying domestic installs until 31 March 2027, Smart Export Guarantee payments on what you export, capital allowances on commercial installs, and time-of-use export tariffs such as Octopus Flux. Payback depends on your roof, your usage and your tariff, so we work it out for your property at survey.
On funding, Home Energy Scotland support covers heat pumps (up to £7,500 grant plus up to £7,500 interest-free loan) and insulation, so if your project bundles one of those measures in, that element can be funded too.
