2. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   The first spacers were made primarily of steel and aluminum, which manufacturers thought provided more durability, and their lower price means that they remain common. However, metal spacers conduct heat (unless the metal is thermally improved), undermining the ability of the insulated glass unit (IGU) to reduce heat flow. It may also result in ...

   Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr per ton of primary aluminum. [18] Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is ...

   The term may also refer to a small openable flap found in the side window on light aircraft. In the United States, the older style of this window is often referred to as a "storm sash". [2] On modern houses they serve on existing windows in order to improve their thermal insulation [3] and soundproofing.

5. Building insulation - Wikipedia

   Sufficient thermal insulation is the fundamental task that ensures a healthy indoor environment and against structure damages. It is also a key factor in dealing with high energy consumption, it can reduce the heat flow through the building envelope. Good thermal insulation can also bring the following benefits to the building:

7. Thermal insulation - Wikipedia

   en.wikipedia.org/wiki/Thermal_insulation

   Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1] Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
