Isover Optima App
An app for surveyors, installers and project managers working to PAS 2035 retrofit standards, with project data and site photography in one place.
- Client
- Isover (Saint-Gobain)
- Year
- 2024

The brief
PAS 2035 sets out how domestic retrofit should be assessed, designed and carried out. Meeting it means capturing the right project data and the right evidence, in the right order, from people who are standing on a site rather than sitting at a desk.
What we built
Isover Optima streamlines project management and PAS 2035 compliance in one app.
Whether the user is a surveyor, installer or project manager, it lets them enter project data and capture the required images on site, so the record is built as the work happens.
