In the August/September 2002 edition of Build you would have received the BRANZ weathertightness poster. This column takes a detail from the poster and provides a ‘good practice’ solution to it.
It may seem too much bother, but adding that extra layer of defence around your windows early on, means less chance of having to fix leaks further down the track.
Why is it that windows fixed with claddings over a drained cavity don’t need a sill flashing, while direct-fixed claddings do?
In this series of articles on window/door installation, we’ve focused separately on heads, sills and jambs. Air-pressure management deals with the whole frame.
In previous editions of Build we’ve talked about window/door heads and jambs. It’s now time to look at sills.
Want a quick guide to installing a window in a wall where a low level of weathertightness risk permits direct fixing of the cladding to the wall framing? Follow these easy steps for a snug-fitting window.
Profiled metal is a fashionable cladding choice today but has been used on domestic buildings in New Zealand since the late 1880s. Back then, timber windows were the norm and standard details commonplace.
Windows and doors are major penetrations in the exterior cladding of a building. It is important that these are weathertight.
High-performance testing of windows for weathertightness developed by BRANZ should give the industry confidence in the weathertightness of window to wall joints.
