Is the Icynene LD foam sweater warm?

Icynene insulation prevents air movement within the walls, eliminating concerns about moisture buildup!

For many years, an old sweater may not feel very warm because the fibers have shrunk and are no longer able to create sufficient air layers, and the same applies to fiber-based insulation materials. Icynene insulation does not allow air movement within the walls and does not absorb water or retain moisture. In the test results of ASTM E2178 in the United States, the air permeability rate of "Icynene LD Foam" was 0.019 l/(s·m²)@75pa, which is below the ASTM standard. [Test Overview] ■ Test Name: Air Permeability Test ■ Test Content - A test specimen is placed in a sealed pressure vessel, and negative pressure is applied by evacuating air from one side to measure how much air flows through the test specimen. * For more details, please refer to the PDF materials or feel free to contact us. * Service Areas: Aichi, Gifu, Mie, Shizuoka, the three Hokuriku prefectures (Toyama, Ishikawa, Fukui), Nagano.
