Fence
specifications and information on construction.
The
fence design is based on two main components. There are upright posts whose job
it is to create the locking together of the horizontal rails. These posts can
also be sunk into the ground to actually support the whole fence without heavy
additional support posts set behind the fence. These posts are a key feature of
the structure, the warp in weaving terms, supporting the weft of the horizontal
rails. Posts are set at 500mm centre to centre and are 50mm square.
The
horizontal components/ rails that make up the bulk of the fence are cut in a wave
form on a specialised bandsaw (patent applied for). The wave has a pitch of 1000mm
and presently, the full length of the rail is 3000mm. The rails are 30mm thick
which gives the finished fence a total depth of 110mm or about 4.5” from the front
of the fence to the back. The rails can be cut to various widths. The standard
width being 75mm (which means it would take approx. 13 of the rails to create
a fence 1000mm high). Small widths of less than 25mm would have to be cut from
high quality sawlogs without defects in order to be structurally sound avoiding
knots, so would be more expensive. Extra wide rails can be cut (up to 300mm wide)
for specialised ornamental fencing. At present only the 1000mm pitch rail is available.
If the thickness of the horizontal rails is decreased, then the thickness of the
supporting vertical post has to be increased so that the total combined thickness
of the fence adds up to 110mm. The reverse also applies. The components can be
produced from a variety of different timbers . Currently main timbers are : Pine
(can be pressure treated with preservative as part of the specification, or supplied
to the customer untreated for them to deal with as they see fit). Tending to be
the least expensive. Larch. Naturally durable heartwood which comprises the main
proportion of the sawn rails and the vast majority of the supporting uprights.
Bit more expensive than pine. Oak. The most naturally durable U.K. timber. Depending
on quality of timber and width of horizontal rails, this can be very expensive
but will last a long time out in the great old British weather.
There
are very many ways to construct this type of fencing using the modular components.
Two examples are pictured. These examples are constructed to give the impression
of continuous rails for the whole length of the fence, the joints being hidden
at the back of the fence, the posts all fixed in the ground. The fence could just
as easily comprise of separate panels between large posts. It could also be a
fence supported behind by larger posts made from concrete or timber thereby holding
the whole fence off the ground by a few cm. The components can be supplied “flat
pack” for customers who wish to erect the fence themselves. Alternatively, Timberweave
can recommend a skilled pair of fence erectors for the job.
