Quality of Construction
Our designs use a small range of quality kiln dried stress graded timber components and the latest in high performance sheet materials and roofing components. This, together with our low overheads mean that designs are effective, modern and “lean” - resulting in an economic design at a surprisingly low cost per m2.
We use only pressure treated exterior cladding for a long life and all components are kiln dried. The roofing systems are chosen to be high performance but light in weight to reduce the need for costly roof trusses and other structural elements.
Many cumulative years of experience go into every structure and by taking care to meet our customers own design and specification criteria, the buildings we create should meet your every expectation for many years.
General Construction Elements - all buildings
|
Sizes |
All external sizes are shown on pricelist / drawings with quotation. |
|
Walls |
3 x 2” nominal (38 x 63 fin) kiln dried CLS timber, dressed & graded to SC3/4 BS5268.
Optionally 4 x 2” nom CLS (38 x 89 fin) (Standard on Clyde model) studwork is placed at average 550mm centres and covered with kiln dried tongue & groove softwood weatherboard.
16 and 19 x 125mm nom as standard (12 and 16 x 121mm finished).
All with Tyvek or Frameshield vapour barrier. |
|
Partitions |
Framework as above but covered full height with 11mm exterior grade OSB Sterling Board.
Optionally 18mm OSB, 12mm MR MDF or Ply, 19mm Sawn.
Optional chatgrills - see weldmesh or steel barred. |
|
Ventilation |
Gable end louvre slatted ventilators minimum 450 x 375mm
Upper wall ventilators to suit studwork.
Ventilation also facilitated by corrugated profile of Onduline. |
|
Doors |
Full 1.2m (4’) opening in Looseboxes as recommended by the British Horse Society.
Stable doors framed in 4 x 2 nom KD CLS timber (as above), lined with 11mm OSB (or to match kicklinings).
External vertical 16 x 125 nom (12 x 121 mm act) PTGV pressure treated softwood.
Other doors to sizes shown in plans, frame ledged & braced, unlined inside.
All doors fitted with fully galvanised fittings including heavy duty tee hinges, padbolts and cabin hooks.
Stable doors have angled bottom door chewstrip protection and kickoverlatches. |
|
Roof
|
Trusses are heavy duty, prefabricated with 3 x 2” nom CLS to approved profile with minimum 15 degree pitch.
External trusses fully clad with gable ventilator.
Internal trusses are either fully clad with OSB (tack/haystores) or partially clad to create cantilever.
Purlins are a minimum 6 x 2 nom CLS (38 x 140 mm fin) or KD softwood to SC3/4 BS5268 and fixed in special BAT galvanised joist hangers at average 515mm centres.
Roof gables are finished with 25mm drip flashing and dressed facia board, also fixed to canopy leading edge.
Insulation & sound deadening properties and 15 year manufacturer guarantee.
In areas of high wind or snow loading and larger expanses of roof, sarking is recommended.
This also benefits reduction in condensation inside the stable.
Also available is profile clad roofing in a range of colours which is laid over a sarking deck as standard. |
|
Treatment
|
All exterior and ground contact timbers are fully pressure treated to BS4072/5268 and guaranteed against rot and insect damage for 15 years.
External panels are finished in an environmentally sympathetic natural light green colour.
This requires no further treatment (eg creosoting) but the use of a water repellent like Thomsons Waterseal is recommended.
The panels are also stainable with spirit based systems to a wide range of colours. |
Permanent Structures
The construction of a suitable base is essential to the long term durability of a building and as such it is worth taking time to consider the location and layout of the buildings in order to optimise the costs involved.
Base for Equestrian Buildings and other Permanent Structures
For permanent structures we would always recommend that the buildings be bolted down, fixing the framework to the concrete beneath. The building principle we adopt in the case of Equestrian Buildings is that they are usually on a concrete base larger than the actual buildings in order to provide a working area to the front. We then suggest that a single course of brickwork be laid to match the walls as shown in the drawing below. The mortar underneath accommodates any small undulations in the concrete and provides the building with a perfectly level line to bolt through. There are many advantages to this, the principal one being that the external cladding protrudes over the brickline giving a water resistant seal keeping floors dry.
Base for Horse Barns (Canadian Barns) and Garages
In the case of buildings such as Garages or Canadian Barns the same principle is used, with the base bricks being laid no closer to the edge of the plinth than 100mm. The base can be made as large as required as long as it is at least 200mm bigger than the building size - many customers also form ramps up to the plinth where the doors are.
Base for Equestrian Buildings - Alternative Option
In several cases for Equestrian Buildings, the same principal is
followed but instead of having a full concrete floor, the concrete is
laid to follow the walls, again with the brickline as before. The
“hollow” centre of each floor is then brought up to level with earth or
graded stone or even peat. The advantage is that urine will percolate
down through the bedding system, dramatically restricting the number of
bedding changes required.

TYPICAL BASE
Saltire Stables will forward
detailed specifications with every baseplan and these show the needs in
terms of fall, strength of concrete and drainage requirements. In all
cases though, the actual implementation of our suggested plan is
subject to amendment to reflect your local situation.
