THE PRESTIGE RANGE DATA AND SPECIFICATION
The positioning and number of doors and windows is decided upon by the customer. Non standard styles and sizes of joinery products can be incorporated when required.
Closed panels built around 150 x 47mm pressure treated joists with a boarded soffit and 18mm moisture resistant floor boards. Laid between the joists is 150mm of glasswool insulation. The floor sections are placed onto 50 x 50mm pressure treated bearers and bolted together.
The cellular construction of all models is the same, what varies is the style of exterior cladding chosen. The 15mm tongue and grooved Scandinavian redwood and the 12mm western red cedar cladding are both attached by hand on site using stainless steel nails. The overlapped boards of the Sunningdale are attached using screws, zinc plated to BS 3382. All cladding is attached to pressure treated battens which create a further cavity, thus aiding insulation and helping to keep the walls free of any damp. The battens are screwed onto a sheet of 9mm OSB 3, between which is a breathable waterproof membrane. These are then fastened to the 38 x 64mm framework. A polythene membrane is attached to the interior edge of the framing before the lining of 9mm MDF or plasterboard is attached. The cavity created is filled with foil backed and faced 60mm polyurethane insulation board which is the equivalent of 120mm of standard fibreglass insulation. The walls receive two coats of matt vinyl emulsion in a colour of the customer‘s choice.
WINDOWS & DOORS
The 24mm double glazed casement windows include weatherstrips, chrome plated lockable latches and 250mm casement stays. The single and double doors are half glazed, although lower glazing panels can be ordered (at no extra cost). The glazing in doors is always toughened. The 44mm thick doors come with three stainless steel ball bearing type hinges, 5 lever mortice lock with a boxed plate (making it compliant with BS 3621 as approved by insurance companies and the police) and a set of Victorian styled, chrome plated handles. The slave door on double door versions has top and bottom fitted bolts and cabin hooks if outward opening, again all chrome plated. All windows, doors and frames are treated with a high performance primer and two coats of Sadolin Superdec wood protection in a colour of the customer’s choice (which can be two tone if a different colour is required inside the building - at no extra cost).
For the standard roof, the construction is made up of 18mm OSB3 boards on top of 64 x 38mm C16 grade rafters. This is then covered with 2 ply asphalt shingle tiles in 1 of 7 shades. The roof is insulated with a 14 layer, foil and foam quilt which is the equivalent of 210mm of standard roof insulation. The underside of the joists is lined with 100mm wide, beaded redwood match boarding. The soffit boards have ventilation grilles fitted to enable the roof void to “breathe”. The 100mm PVC guttering attaches to the facia boards and one down pipe is installed. For both roof options, the slate effect tiles or cedar shingles are nailed to pressure treated roofing battens using copper or stainless steel nails respectively. These sit on top of a breathable, waterproof, roofing membrane. The hips and ridge are finished with code 3 lead flashing for the slate effect tiles and dedicated cappings for the cedar roof.
All wiring goes back to a consumer unit situated within one corner of the building. The sockets are situated at skirting board level and the spotlights are mounted on the eaves height pelmet. An optional three compartment skirting trunking can be specified, which will have at least one compartment spare for the running of data or voice cabling. All electrical installations are carried out by an NICEIC approved contractor. The customer is responsible for running the mains supply to the site of the Garden Room, though this work (along with the connection within your property’s main fuse board) could be undertaken by us for an extra charge, if required.
All of the Prestige Range of buildings are guaranteed for 10 years against manufacturing defects and decay (exterior timber should be retreated each year or in line with the recommendations of the preservative manufacturer). Electrical goods are covered for 1 year.
