Window Installation in Germany using Compressed Foam Tape

Installing German windows in a masonry block building with beautiful copper roofing details.

Step-by-step (as near as we can tell):

• First they remove the sash and shipping straps.
• Next, they apply expanding foam tape to the outside jambs and head.
• Set the window frame into the opening using a jig to place it the correct (and consistent) depth in the opening and blocks to shim it level.
• With the base level, they plumb and square the frame.
• Holes are drilled through the jamb into the masonry block. the hole is reamed as a countersink for the masonry screw that goes in next.
• The clamps are removed and an air barrier/vapor open tape is applied to the bottom of the window. It s sealed to the masonry sill with adhesive.
• An expanding foam is sprayed into the gap between the masonry sill and the window sill.
• An air barrier/vapor open tape is applied to the inside bottom of the window and the material is bedded in adhesive caulk.
• The exterior sill is preformed and applied next. It screws into the window sill.
• The sash are reinstalled and the hardware checked/adjusted
• On to the next window.
