Key takeaways
- A 74m² loft with no usable boarded platform, where boarding straight onto the joists would have compressed the 270mm mineral wool beneath.
- EcoTrust Roofing & Insulation Ltd installed a Loft Leg raised system with 18mm storage boarding over three days.
- The full 270mm of mineral wool was retained uncompressed below the platform.
- The family gained a stable walking and storage surface, with a 10-year workmanship guarantee on the installation.
Why they called us
A growing family in Preston was running out of storage space downstairs and wanted to use the loft safely. They did not want boarding that would flatten the insulation or create an awkward, unstable area to walk on.
The goal: safe loft storage without crushing the insulation beneath the boards.
What we found on survey
The 74m² loft had no usable boarded platform and needed a raised structure above the insulation zone. Boarding directly onto the joists would have compressed the 270mm mineral wool and reduced its thermal performance.
That is the part most people do not see coming. A direct-to-joist board squeezes the insulation and creates cold spots in the rooms below — so the family would have gained storage and quietly lost some of what the insulation was doing.
What we did
We installed a Loft Leg raised system, retained the 270mm mineral wool beneath the platform and fitted 18mm storage boarding over three days. Raising the deck above the insulation keeps it uncompressed while still giving a stable walking and storage surface.
The result
A usable loft storage area with no reduction in insulation depth below the boards. The finished raised system was supplied with a 10-year workmanship guarantee.
