#65 YKKの内窓を取り付けました その１ 内窓の費用、施工具合、安くするコツを紹介します！

Today, I installed YKK interior windows, and I'd like to share the cost and installation process. Interior windows look like they were added later and are unattractive, so I thought I wouldn't install them, but my house's windows are a composite sash made of resin and aluminum, and are filled with low-e argon gas. But they're still cold in the winter. Then I found out about a subsidy called the "Advanced Window Renovation Project," and after researching, I found out that interior windows could be installed at a very reasonable price, so I decided to put up with the unattractive appearance and go for it. ■Related Videos ・#65 Installing YKK Interior Windows Part 1: Introducing the cost, installation, and tips for saving money on interior windows! 　   • #65 YKKの内窓を取り付けました その１ 内窓の費用、施工具合、安くするコツを紹...   ・#66 Installing YKK Interior Windows Part 2: Introducing the pros and cons of interior windows!    • #66 YKKの内窓を取り付けました その２  内窓の良い所、ダメな所を紹介します！   #67 The Effects of Interior Windows (Winter Edition) Will installing interior windows in a Tama Home make it warmer?    • #67 内窓の効果（冬編） タマホームに内窓を付けると暖かくなるのか？
