Window rubber locking strips

[uniB]

I thought it was a mistake but it seems the locking strips in window rubbers are s'posed to be on the outside – does it matter if they are the other way round so the strip is on the inside – does it effect water tightness?? Seems a bit silly having that bit on the outside for obvious reasons.

The slots aren't straight, and are designed so that the lip of the rubber sits tight against the paintwork and the glass on the outside, less so on the inside. They would be less effective if used inside out. Having said that, I have just fitted a new set, (insert on the outside), and to be absolutely sure I used sealant between the rubber and paintwork, cos water had obviously penetrated before causing the metal edge to rust.

Use them with the insert outside.

Hi,
Locking strip is usually on the outside.
The Seal Direct catologue suggests putting a silicone sealant in both grooves when using these Claytonrite type window rubbers. Their method of installation (and mine) is to put the rubber around the aperture and then add the glass. Some members put the glass around the rubber and then string the rubber into the aperture.
