What 保温工事 do
An English description is being prepared. Japanese description:
施工分野は、大別すると建築設備の保温・保冷工事とプラント設備の保温・保冷工事に分けることができる。保温・保冷工事は、熱の損失を防ぐ省エネルギー対策として重要な意味をもっている。保温・保冷工事には、人造鉱物繊維保温材、無機多孔質保温材、発泡プラスチック保温材の3種類の保温材が使用され、板状の保温板、フレキシブルなフェルト、保温帯、ブランケット、パイプの外径に合わせた保温筒として用いられる。
工事対象物の温度（高温・低温）、形状（装置、タンク、パイプ）、目的（耐火・保温・火傷防止・保冷・防露）に合わせて保温材をのこぎり、パン切りナイフ、カッターナイフ、電気こてなどで所定の厚さに裁断加工し、鋲（びょう）、ボルト・ナット、針金、金属性バンド、金網などの補助材を使って取り付ける。保冷・防露工事では、周囲に空気が流れ込んで結露しないように、保温材の外側をフィルムやシート、防水紙などで覆う。
居住部分の人目につく箇所の仕上げには、美観が要求されるため、綿布のテープなどをらせん状に巻いたり、カラー鉄板などの金属板を使って仕上げる。

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →
