the black rubber sealing strips on the top of our double glazing on the
inside of the frames are falling down. I can poke them back up again, but
they need something to hold them back in place.
i thought of putting in a thin strip of glazing putty, but i guess its a bit
messy and difficult to get a clean straight finish, and could be an
overkill. any other suggestions or tips for a novice please? which of the
silicone sealants might be the easiest to use and easiest to clean off if i
made the expected pig's ear of it?
One option is superglue (cyanoacrylate adhesive) in the gel form so that it
shouldn't run down the window. Either squeeze a narrow bead along the
sealing strip or along the recess between the frame and glass, depending on
what looks the best approach. Clean the rubber strip and recess first if
necessary. Have a damp cloth handy in case any of the adhesive should
squeeze out onto the rubber strip, glass or frame. Another option is sealant
if used sparingly and any excess is easy to wipe off with a damp cloth if
done early on before it starts to cure. Sealant can be black, white or clear
(clear appears milky) but if all excess is to be wiped off then the colour
might not matter.
Different dimensional thicknesses of locking strip are available. it sound
as if yours may have been fitted with slightly thinner strips than were
really required, or they may have shrunk over time.
If you obtain and fit new strips ensure that you compress them during
fitting rather than stretch them/ fit them "neutrally", as they contract
with age and you will find gaps appearing in the locking strips at the
corners of the windows. Cut them 1/4" or so long at the completion end of
each run (after compressing them during fitting) and compress the seal a
little more to "lose" this final 1/4", this will also help to ensure you
don't end up with gaps.
