Final Thoughts

The application of Liquid Foam Insulation (LFI) is currently viable and commercially available in limited application with limited levels of insulation available. Subsoil heat storage systems such as the SHCS have been shown by this and previous studies to be economically viable in terms of their energy saving performance, and more viable than thermal mass […]

LFI/SHCS and Nightly Lows

LFI and SHCS together kept the greenhouse warmer than SHCS alone during the same period, and warmer than LFI alone for the same ambient lows during a different period. The increase in temperature differences in the LFI/SHCS greenhouse over SHCS or LFI alone grew for nights with lower ambient lows. During the entire period, the […]

Issues for Implementation of LFI

Liquid foam insulation is a long-known technique (Cunningham, 1984), but it has only been commercialized recently through significant, multi-million dollar investment (Sunarc of Canada, 2008). There is no evidence that LFI will be distributed or adopted in a grassroots fashion, despite the efforts of some (Elliot, 2007). Based on the experience gained through conducting this […]

Best Practices and Optimization

The public record regarding liquid foam insulation is not sufficient for best practices to be identified here. However, Sunarc of Canada Inc. has almost certainly identified many of the critical best practices in its private product development process. Its patents do not discuss what factors increase the insulation value of foam other than claiming that […]

LFI Discussion

Discussion of Inconclusive Evidence and Further Research During the day a 0.6 m foam-filled cavity drastically reduced light levels, but the deep shade subsided quickly, in around one hour. In order for foam to be an effective shade agent it needs to create the desired levels of shading and maintain them for a sufficient length […]
