Thing to Know Before you start

  • Check all the specification before starting the installation process (size, style, and handling)
  • Check opening sizes before removing the existing window.
  • The size new UPVC window should be 10mm less both in terms of height and width.

Starting the Process

  • Level the cill with approximately 5mm clearance between the cill and the brickwork by using plastic packers.
  • Using the 8 x 100 mm fixing bolts secure the cill to the brickwork by positioning it approx. 150 mm from each end and at 600 mm centres.
  • Along the back edge of the cill, run a bead of silicon.
  • Secure the end caps into the position by using silicon.
  • Mark the glazing beads after removing them from the window frame to ensure that they can put back in their original position later on.
  • Snug the base of the window against the cill up stand to fit the new window in the position and ensure a tight seal in the bead of silicone.
  • Using the plastic packers, wedge the window into the position.
  • Try not to bend the framework.
  • To enable access to the outer frame jambs, open the vents of the window. Secure the bottom of the window by using the screws.
  • Using 8 x 100 mm fixing bolts, secure the jambs of windows in the brickwork surround.
  • The next step is to close and lock all the opening sashes and that the window is adjusted according to the outer frame.
  • It is important to position 25 x 100 x15 glazing bridges in the frame recess.
  • Place a 28 x 100 x 5 glazing packer on the bottom glazing bridges positioned in the previous step.
  • Put the glass sealed unit in the aperture while keeping it assured that the glass is in the centre when being opened. Do not put undue pressure and rest the glass squarely on the glazing packers.
  • Position 2 mm glass packer using hand pressure to square up where necessary.
  • Open the sashes gently to check whether binding occurs or not within the locking system. You may need to make minor adjustments to get the perfect squareness.
  • Place the glazing beads that you marked earlier into their original position. Top one first, followed by bottom and sides respectively.
  • Gun a bead of silicon between the window frame periphery and outside masonry carefully.
  • Gun a bead of silicon between the window from the periphery and the inside plaster and let it dry for at least an hour.
  • The final step is to remove the protective tape from the frame and clean the surface.
