How to Fit a Double Glazed Window
Data on how to fit a double glazed window including removing window beads, plumbing fixtures drinking glass, window sills, end caps and fitting a window frame. We talk you through fitting a double glazed window so you can meet how it is done.
To fit replacement doors and windows FENSA registration is required. All the same the basic process of what's involved is described below.
Double-glazing mostly comes in three parts, the frames, the sill and the glass. When you lodge, they volition arrive separately with the beads in the frame so you can pretty much run into how the glazing beads fit in. See besides our project on Upvc conservatories for more data on windows and doors.
Remove your existing windows advisedly. The less mess you make of the walls the less work you volition accept to exercise afterwards on. Check you have non damaged whatever vertical damp proof courses or that they accept not pulled out with the former frame. If they accept, slide them, or new lengths, back into position. Take a look at our projects on replacement windows and how to remove window and door frames.
Most mod windows come with trickle vents in the elevation department of the frame. These vents permit warm air that has built up in the window recess, to flow out rather than striking the cold glass or frame and condensing. See our condensation project for more information on this.

Frame and Chaplet
Sealed units (the drinking glass) are two panes of glass kept apart past a coloured spacer bar (mostly silvery or brown). This is filled with silica crystals. These crystals soak up the wet to keep the air gap betwixt the panes clear. You lot should be given a 10-year guarantee on these units. The glass will be cut to fit the frame y'all order then you but have to worry most getting the correct size frame. The glass will also be cutting to allow room for the heads of the frame fixing screws at the side of it.

When y'all insert the glass you will need to space it out so the borders are equidistant in the frame. In the case of a "barred" unit, which is a sealed unit with inbuilt glazing bars to make information technology expect every bit if it is lots of small sections, you will need to make sure the glazing confined look admittedly horizontal and vertical. This can also be washed using the spacers.
The beads, if installed when you lot accept delivery of the frame, can be removed using a sharp scraper or chisel, this will give you a clear view of the rebates that will receive the glass.
Window Sill and End Caps
The frame will come separately to the sill and the sill will probably take to be cut to length on site as commonly you get a little extra to play with. The sill in most cases volition also come up with some end caps which need to be glued on to each cease of the sill with a special PVC superglue. Occationally the sill and window will come up with the glue just in most instances you volition have to purchase this seperatley. The glue can be purchased from nearly window and glazing suppliers.
The sill sits on the height of the outside skin of the wall, on a mastic, or sand and cement bed. A bead of silicone is applied to the top of the sill and the frame then sits on that. The back edge of the sill volition have a footling upstand against which the window volition butt and this is where you put the silicone. Exercise not seal the gap which will be between the bottom front edge of the window frame and the top of the sill. In that location are drainage holes in the bottom of the frame and any h2o that does get into the frame tin run out of these holes and run off the sill.

Types of dissimilar thickness spacers
The fixing holes are drilled one time the beads are out and the screw heads are covered by the sealed unit of measurement when it is placed in the frame.
Put the frame in and square it up within the opening using the plastic spacers. Y'all can ask to have a variety of spacers sent with the windows you order.
Choose a solid area of wall and drill through the frame and wall. Countersink the fixing hole gently, the pvc section here is not very thick and you but want to be able to lose some of the heel of the fixing.
Insert the correct length "frame gear up" screws, which come complete with plug. Take the screw from the plug and button the plug in first, (you may have to give the plug some help to get it through the frame and firmly into the hole in the wall) then push the screw in as far as yous can by hand, then tap it in a bit further with a hammer and finish it off with the battery screwdriver. See our video on the bottom of our folio on a complete guide to fixings.
Endeavour and get your fixings either well-nigh the spacers yous accept used, or in positions where the frame is touching the reveal. This volition brand sure you lot practise non bow the frame when yous tighten up. With opening windows the fixing goes in the rebate that does not foul the endmost of the window.

Countersinking spiral heads into window frame
Place the glass square in the frame, using spacers to ensure it is square.
Insert the beads pushing the shorter sections in first.
A little tip here is to put a tiny driblet of washing up liquid on the rubber of the bead to allow you to slide the bead up the glass as you button information technology into identify.
Clean glass and Upvc and enjoy your handywork.
In that location is a huge range of window types and styles available on the market place today to cover the e'er-irresolute tastes in design, way, security, technology and efficiency. Although we would like to list them all here for to view in that location are simply likewise many.
