Insulate Older Homes with Modern Technology

Aside from insulation machines and blowers, what are the new ways on which you can insulate your home? You can start by removing siding from the wall, drill a hole then fill it up with insulation.
The newest materials you can use are wool, cotton, foamglas and silica aerogel. Foamglas is a new insulation material that is 100% waterproof, inorganic and high compressive. Wool is an all- natural and inherently fire-retardant material while cotton can now be found in 100% post-consumer recycled formulations. Silica aerogel is a lightweight and translucent material that is used to fill up glazing panels and can provide up to R-values up to 20.
