A note on sourcing. Every figure here comes from a SprintlyWorks client engagement. Clients are described, never named. Where a figure is identified or modelled rather than banked, the line says so.
01

The problem

Data gaps on technical performance, inconsistent fire resistance, and limited proven bio-based options hindered informed decision-making.

High production costs, scarce market-ready solutions, and significant R&D requirements delayed the adoption of sustainable materials, risking lost market share in the growing low-carbon construction segment.

02

What the sprint set out to do

  • Identify and assess bio-based, recycled, and recyclable core material alternatives for PIR and mineral wool.

  • Evaluate and compare technical, operational, economic, and sustainability feasibility of shortlisted materials.

  • Develop and recommend adoption pathways and pilot strategies to enable scalable integration into the client’s product portfolio.
