They’re cheaper because of both the benefits they offer and a decrease in aluminium’s price, which makes them more cost-effective. The aluminum windows and doors are available in various styles, shapes, and colors. They’re also highly durable, so you’ll never have to replace them. Furthermore, you can choose smaller frames, allowing more light to enter your home with aluminium fabrication Leeds. Besides, aluminium windows are highly insulating, making them a win-win for everyone.

Before starting, be sure to read this guide completely. You want to check the opening’s size against the window’s outer frame.

Step 1:

Check to ensure you have everything – cills, end caps, gaskets, packing, etc.

Step 2:

Make sure you’ve got a glazing wedge. Make sure the cill is in the right place. Ensure that the cill is perfectly level. Apply sealant to the wall and the surrounding area.

Step 3:

Now you can put the window on the cill and in the opening. Make sure the window is level, plumb, and square by putting packers in the corners. Measuring the diagonals will let you know if the frame is square. There shouldn’t be more than 1 or 2mm between A and B.

Step 4:

Make sure you screw into the thermocouple at the bottom of the cill using two screws (do not screw through the drain holes).

Step 5:

Whenever possible, the first fixing should be within 150mm of each corner and at no more than 600mm intervals. Do not overtighten the first fixation. Put packing around the fixings, so the frame doesn’t distort. Using foam will not be a substitute for screwing, and you should be careful not to get it in contact with painted finishes or trickle vents. Both sides of the outer frame should be fixed into the brickwork. The head should be fixed into steel or brick. If the diagonals aren’t equal, fix them. You can use fixing lugs if direct fixing isn’t required.

Step 6:

Take off the glass beads. You might have to trim back the external gaskets. All windows that open need to be ‘toed and heeled’ properly. The windows won’t work if you don’t heel and toe correctly. Pack the bottom corner of one hinge side with the glazing packers provided and the opposite with the top one. Install extra packers where necessary to fill in any slack caused by lifting the glass. Beads must be reinstalled. stuff the gaskets enough to account for a small

Step 7:

Install the wedge gasket. Make sure you stack the gaskets a little high to allow for shrinkage. The fit is tight, especially on thin sashes, and they can be hard to put on. Using a glazing wedge, place the wedge between the glass and bead, then the wedge should hold the glass in place.


  • Warm soapy water softens the gaskets.
  • Slide the gasket in using glass cleaner or something similar.
  • Put a glazing packer near every corner so you can maintain the gap.

Step: 8.

Clean the silicone seal internally and externally.
