The only manufacturer I've seen on here who specifies that the underside of the external sill is sealed. Top class.

Thanks for this very informative video, this is very handy to watch if you are about to have new windows fitted so that you can scrutinise the fitters and their work when they are fitting windows that you have paid 1000's of pounds of your hard earned money out on so that they don't tuck you up

Nice UPVC Window Installation Guide...this is from a while ago but it's still good.

Great demonstration.

Very useful for new and old worker who  is working in this line. Thanks for shearing

Goo video. I installed 2 French doors in my extension last week. I will take them down and redo them based on this video. Good job.

do not fix up it can cause water to enter the frame above, if a fixing is needed use a fixing strap

good job I'm also know how
do install the window,i'm working in muscat,and they are working without safety please advice to them wear handglause.

Simple mate, just de-glaze the new window + it lessens the weight ready for installation

We have a upvc window installation team

thanks jimbo , iv been fitting windows for over 15 years , so got a rough idea of how it works , I was just making the point that somebody said that "the window should arrive glazed" which obviously it shouldn't due to weight and impracticality..

i would say putting a packer under the middle of the cill is a bad idea as it distorts the cill id prefer to level from under the mullion thats my 2 peneth
