3. Take the first beam
line up lower edge of beam with line marked on the wall. When in
place mark through top hole onto wall where it is to be fitted
(always drill centre brick and not mortar joints)
4. Drill a hole
with 16mm masonry bit through brick into cavity. This is almost
the length of a standard 16mm bit. The bolt should open up inside
the brick. It is important to ensure all your fixings are secure
as this provides the strength required to support both the canopy
and any snow load during winter.
5. Place a bolt in
beam and insert into wall making sure the head of the bolt is
gripped up.
6. Hammer bolt
home, preferably use a nylon hammer or a block of wood and metal
hammer, so as not to damage the bolt head. Tighten bolt securely
but not fully.
7. Check the beam
is level on the wall, then mark the bottom hole, now push the beam
to one side and drill the second hole. Insert bolt as before.
Tighten bolt securely but not fully
8. Level and fit 1
aluminium purling to form a wall plate drill and fix to wall. This
then lines across the top of the beams and give the location of
the next beam. Fix all beams into place. Now Fix the aluminium
purling to form sheet supports at approx 610mm centres from the
wall plate. Before fascia is fitted level all beams to the wall
using packing as required. Retighten bolts to fully secure.
9. Cut fascia to
length notch out to suit end beam fascia platform and lip.
10. ( Please space
your sheets evenly so as to ensure you cover the roof fully, to do
this you may wish to place all the sheets in to place and mark the
position of each sheet before fixing any of the sheets, then
remove all the sheets except the first two. This method will also
provide you with another chance to check for square ness. )
Lift first roof
sheet in to place ensure the sheet is square with the top wall
plate and the lower fascia and side, then lift on second sheet
centralise and overlap on top of the first sheet, again check for
square ness silicone the front edge and the overlap between the
sheets before fixing the sheet in to place, before fixing the
second sheet lift the third sheet into place and silicone the
joint, You may wish to complete your flashing as you complete each
section above individual sheets as access is easier at this time
rather than after completely fixing all sheets.( Please space your
sheets evenly so as to ensure you cover the roof fully, to do this
you may wish to place all the sheets in to place and mark the
position of each sheet before fixing any of the sheets, then
remove all the sheets except the first two. This method will also
provide you with another chance to check for square ness. )
Continue and repeat
process for other sheets.
Wipe down canopy.
Now install your
rainwater guttering and down pipe.

Frequently Asked
Questions
|
|
- What about
the stress factor on the wall?
The stress on the wall is negligible due to the flexibility
and lightness of the GRP Beam.
- What about
cement block, breeze block, and single leaf buildings?
Fine, as long as the construction is solid.
- What about
rendered walls such as pebbledash?
When fixing to a rendered wall it is preferable to chip away
the rendering where the beams and sheeting will lie against
the wall. (Chip away a small line first to see the line of
the brick joints.)
What about
bungalows?
It is possible to fix the Concept canopy to a bungalow.
There should preferably be 900mm of brickwork above the top
bolt in the beam. Whether this is feasible will be
determined by the height of the wall. If it is not possible
to have 900mm of brickwork above the beam fixing, but it is
possible to fix the canopy at the top of the wall, then
arrangements to spread the load over the wall should be
considered, as below using brackets we can supply.
