Window Installation Questions
I am obtaining quotes for replacement windows in my home. Today I received a quote and when I asked the installer if they used spray foam - he said no which I found odd. Is spray the preferred insulation for new windows? Should I insist on spray foam?
Second, I have a brick home with an exposed steel lintel over the windows. Should the lintel be covered during the install with capping or left exposed? I've had various answers from installers.
Lastly, is there any preference or advantages to pvc coated coil for capping versus just painted or aluminum coil?
