Eaves Beam Installation
Step 1 - Measure overall external width of
conservatory along front edge, add 15mm
to each side, if cladding is used for gable
triangle(s) and cut eaves beam
Silicone seal around
glazing bar top caps
against back plate
When cutting
glazing bars
allow 40-60mm
overhang in gutter
fix position using self tapping screws
at approx 1000mm centres. Re-fit
internal PVC cladding
Step 4 - Decide the position
of the glazing bars and cut a
notch in flipper gasket where
it crosses the eaves beam. Fix
glazing bars down using self
tapping screws
