Window & Door Frame Flashing & Meter Box Installation

Today we concentrated on getting the window & door frame flashings up.  First step was to make sure that there was space available for the flashing to sit comfortably in.  There needed to be an overhang of 50mm on each side of the frame with the flashing, so sometimes this required part of the cavity battens to be checked out so that it could sit flush against the wall (as pictured above).

Once the space was cleared correctly, the flashing could be fixed to the wall.  First rubber stops had to be stuck to each end of the flashing with sealant.  Sealant is also run along the top of the frame so that it creates a seal between the frame & the flashing which should sit hard up against each other.  Holes are pre drilled into the flashing & clouts are used to fix it to the wall. 

Additional building wrap is then fixed onto the wall so that it overhangs over the flashing & then vermin strip is stuck on 

10mm above the flashing.  Cavity battens are then attached (as done on the rest of the house) with a section chiseled out so that it sits comfortably in the vermin strip.

This process was repeated on all openings, with the only difference being for the large bifold doors.

The flashings for these were attached 5mm above the frame work, as this was specified in the manufacturers notes.

This was done to account for the movement in the door when it is being opened & closed, as it can cause the frame to move.

We also inserted the meter box today.  Metal flashing was pre attached to the unit using rivets & was then placed into the opening & attached with clouts.
