Adam owns his home, Blackacre, which was mortgaged to Bank by a duly recorded purchase money mortgage. Last year, Adam purchase money mortgage. Last year, Adam replaced all of Blackacre's old windows with new windows. Each new window consists of a window frame with three inserts: regular windows, storm windows, and screens. The windows are designed so that each insert can be easily inserted or removed from the window frame without tools to adjust to seasonal change and to facilitate the cleaning of the inserts. The new windows were expensive. Adam purchased them on credit, signed a financing statement, and granted a security interest in the windows to Vend, the supplier of the windows. Vend promptly and properly filed and recorded the financing statement before the windows were installed. Adam stored the old windows in the basement of Blackacre. This year, Adam has suffered severe financial reverses and has defaulted on his mortgage obligation to Bank and on his obligation to Vend. Bank brought an appropriate action to enjoin Vend from its proposed repossession of the Vend from its proposed repossession of the window inserts. In the action, the court should rule for 
Bank, because its mortgage was recorded first.  Bank, because windows and screens, no matter their characteristics, are an integral part of a house.  Vend, because the inserts are removable.  Vend, because the availability of the old windows enables Bank to return Blackacre to its original condition.
