   This is a list of insulation materials used around the world. ... Polyurethane rigid panel (pentane-expanded) aged 5–10 years 2.54: 1 0.97: 5.5: 38

3. Vacuum insulated panel - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_panel

   A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials. [1] [2]

4. Insulation system - Wikipedia

   en.wikipedia.org/wiki/Insulation_system

   Basic insulation is any material added to protect a user from accidental contact with energized parts. Supplemental insulation is rated to withstand 1500 volts AC. Double insulation is a design concept where failure of one insulation system will not expose the user to a shock hazard due to the presence of a second independent layer of insulation.

5. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Rigid panel insulation, also known as continuous insulation [15] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.

6. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmental investment for buildings.

7. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   For comparison, phenolic foam insulation has a k-value of around 0.018 W/(m⋅K), [23] while wood varies anywhere from 0.15 to 0.75 W/(m⋅K), and steel has a k-value of approximately 50.0 W/(m⋅K). These figures vary from product to product, so the UK and EU have established a 90/90 standard which means that 90% of the product will conform to ...
