New HFO blowing agents for spray foam will make it over 1,000 times less harmful to the climate

...insulation is a petroleum-based product and nothing will change that. But that was never the biggest problem the 'eco' building community had with foam insulation; the main issue was the inclusion of chemicals with a global warming potential (GWP) that was over a thousand times worse than carbon dioxide as a green hous...

How insulation works

...insulations varies in the range of R3 per inch to around R6 per inch. The higher the number, the more a material resists heat transfer. A typical section of a cold climate wall will be in the range of R18 to R24, depending on materials and regional building codes. That covers the insulation material, but there is more ...

Understanding sound transmission in buildings

...insulation a construction can provide. During the design of a building, all possible flanking paths must be considered and steps taken to minimize their effect. Otherwise, the net sound isolation can be much less than that expected from laboratory testing. With good design of the junctions between walls and floors ...

Properly insulating basements and concrete slab floors

...insulation at all seem sufficient, so basements built to code are still often chronically under-insulated. Current building codes vary by region and state, but what is consistent is that if you insulate to the minimum requirements of code, your basement will still account for a significant and unnecessary portion of ...
