is it normal for a new window to have to have silicone put on under the beading to make it draft proof?

got new windows fitted ,the company r a bit of a joke ,well more of a nightmare i should say,well as our weather has been pretty bad of late,wet and windy, the windows r letting the wind in so the other week one of there fitters came out with his silicone gun took off the beading which surrounds the window and filled it with silicone, presumably to stop wind getting in ,surely new windows should all be draft proof when they r made,windows were put in end of september,trading standards r now involved surely we shouldnt need to except botched up windows?
the window is a full pvc unit glass at top with pvc panel at bottom there was a draft coming in the top of the th
the window is a pvc unit complete -window and bottom panel all pvc with beading around it .we were getting mega drafts from the top and bottom of the panel so we complained they removed the beading and sealed with silicone and put beading back on surely this is not right for a new window
If they are wooden window frames…it is a good idea to use silicone under the beading. This stops water getting in and rotting the wood! BUT…if they are Upvc windows then there should be no need for silicone under the beading. It should already have a rubber or neoprene strip to seal against water and wind. Silicone around the edges of the frames yes…not anywhere else!

Sound like they’ve been badly fitted. Or badly made units.
I purchased a upvc window from a decent firm and fitted it myself- its not rocket science. You’d expect a window firm to know what they are doing.
Get them on the phone and make a fuss!

youve been conned the beading is covering thier sins.the window has been under measured.their should only be one eight gap all round. then a silicone seal to make it weather proof.i’d demand they replace it.

no, a good window, properly installed should need no caulk to seal it, they need to "breath" so moisture doen’t stay in and damage anything…the only caulking necessary is cosmetic stuff that the painter will do (interior and exterior) but that is not structural caulking, it is merely cosmetic
ebo is right demand they redo it and raise the devil ’till they do
sue if you have to.

Timber windows expand and contract with changes in humidty and using glazing silicone is fine as long as it is on the face of the glass between the beading and not in the airflow void.
must add though that most windows come with the weather seals
