NOTE: It is not recommended to
use a tree for a sail fixing due to the
overall strength required.
If you intend to fix your sail to a fascia, the use of a fascia support is
strongly recommended. The facia support will reinforce the overhangs
of rafters or trusses and provide a stronger connection between the two
with improved strength. Facia supports are available from your local
hardware centre.
If additional posts are required it is recommended to use galvanised or
painted posts to prevent rust. Steel posts are available from your local
hardware centre or steel supplier, and can be cut to predetermined
lengths and colour matched to your sail and environment.
It is recommended to use a round steel post with a minimum diameter
of 90mm, or a 90x90mm square steel post. Post wall thickness should
be a minimum of 4mm.
Alternatively, the use of treated softwood (H5 level treatment) or
Hardwood of durability Class 1 is also suitable. The timber post should
be a minimum 125mm in diameter. Your local timber supplier can assist
you in your selection.
Post lengths should be calculated taking into account the proposed
height of your sail plus the depth of your footings.
It is advisable to lean posts at an angle of 5 degrees, sloping away from
the centre of the sail for additional support.
