2. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...

   It has a high recycled content and less risk to the installer than fiberglass (loose fill or batts). [29] R-Value 3.4 – 3.8 (RSI-0.60 – 0.67) per inch (imperial units) Loose fill insulation fills the wall cavity better than batts. Wet-spray applications typically seal even better than dry-spray. Class I fire safety rating

   en.wikipedia.org/wiki/Cellulose_insulation

   Subsequent real world surveys have cellulose performing 20–30% better at reducing energy used for heating than fiberglass. Compared to closed cell, Polyurethane foam insulation (R=5.5 to 6.5 per inch), cellulose has a lower R-value per inch, but is much less expensive; foam has a higher cost per equivalent R-value.

8. Insulated siding - Wikipedia

   en.wikipedia.org/wiki/Insulated_siding

   The rigid foam insulation fused behind the siding panel reportedly makes insulated siding more durable than traditional vinyl siding. The rigid foam backing is precisely fitted to the contours of the siding's exterior surface, preventing the vinyl component of insulated siding from sagging, warping or shifting. Manufacturers claim that ...

9. Rigid panel - Wikipedia

   A multi-family residential building under construction with rigid panel exterior insulating sheathing. Rigid panel insulation, also referred to as continuous insulation, [1] can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR), and polystyrene, or from fibrous materials such as fiberglass, rock and slag wool.
