What this video covers

The crew of the 45-ft sailboat *Uma* installs thermal and acoustic insulation using a multi-stage process involving spray cork and expanded cork sheets. After applying two initial layers of spray cork, they glue one-centimeter-thick sheets of expanded cork to the hull to improve energy efficiency for future electric HVAC systems.3:36 Because the hull interior lacks right angles, the crew fabricates custom adjustable angle-measuring tools to template and cut the cork panels for tight-fitting installation in nooks and cubbies.7:10 They fill remaining gaps and cracks by hand-packing them with cork material before applying a final spray coat to create a uniform finish.20:33 The process requires extensive masking with plastic and tape, which they remove after the final layer cures.22:23 The insulation significantly reduces interior echo and sound transmission.10:50
