This graphic demonstrates how LeakSignal® Color-Changing Spray Foam Insulation reacts when water penetrates a roofing system.
A leak originating under the asphalt shingles passes through the wood roof sheathing, contacting the spray foam insulation below. Upon exposure, the foam visibly transforms from yellow to deep blue — providing a clear, instant visual indicator of moisture presence.
The included swatch bar shows the Moisture Response Spectrum, highlighting how LeakSignal shifts from light aqua to dark navy based on moisture severity.
To the right, a branded LeakSignal canister reinforces the product’s packaging and applicator style.
