Step 3 – Glazing Packers
The use of glazing packers is essential to allow the windows of doors to function properly. The recommendations for packer locations must be followed on all side hung windows or doors, we call this principle ‘Toe and Healed’.

With the door in the open position lift the handle and turn the key the operation should be smooth Silicone 2 packers in the bottom corner of the hinge side and 2 packers in the top opposite corner leave to dry. Close the door and see how far apart the joint lines of the sash corner are lower than the joint line of the frame this will be the amount of packing which will be required to heal and toe the sash
Insert the glass into the rebate apply two beads tempary to the left and the right side of the sash to stop the glass falling out during adjustments. Insert another 2 packers into the bottom hinge side lifting the glass first with a glazing shovel, making sure that the glass units are fully supported by the packers. In the opposite corner using the glazing shovel lever the glass away from the top of the frame creating a gap, this will cause the sash to be lifted above the glass to insert another 2 packers. Close the door and check that the lines now line through our the sash line is slighty higher that the frame line The packers MUST be adjusted until the frame diagonals are equal. It is recommended the packers are secured in the ‘final’ position with silicone to prevent them working loose during operation.
