Installation: |
The coursework should be built to the level of the
sill ensuring that it is flat, level and free from excess
mortar. Locate the closure in the required position,
ensuring that it is facing the correct way and prop
vertically. Build up the outer coursework by a single
level on one side and butt up the frame. Confirm that
the frame is correctly positioned horizontally and held
firm vertically, then check for accuracy in both planes,
ensuring that there is no twisting. Use a tape measure
and spirit level to confirm this.

The unique Cavalok Corner Block enables
a window frame former to be assembled easily and quickly. Simply
measure and mark the required window opening height x 2 and
width on the closure flange taking into account any appropriate
expansion tolerances of the window. Using a solid surface place
the closure, box section down, and support under the flanges
using timber blocks. To achieve an accurate, clean cut, we recommend
the use of a double mitre saw. |
