Cold storage flips the usual problem: you are keeping heat out and holding a precise low temperature in, which makes the envelope the entire game. Any gap or thermal bridge is an energy leak and a frost point. Closed-cell spray foam is well suited because it delivers a continuous, seamless, vapour-controlled layer with no seams for cold to escape or moisture to enter.
What cold storage demands
- Continuous insulation: no seams, no thermal bridges - a monolithic closed-cell layer.
- Built-in vapour control: at depth, closed-cell manages the vapour drive that would otherwise ice up a conventional assembly.
- High R in minimum thickness to preserve interior space.
The application
Coolers, freezers, food and industrial cold rooms, and refrigerated conversions all benefit from a sprayed envelope that seals as it insulates. It is precision work - specced to the temperature and the manufacturer data sheet.
