Garage Construction

Premium Extra-High Garages are available in single or multibay blocks. They have a monopitch rear draining roof with a choice of two front heights - 3.10m (10ft 2in) and 3.60m (11ft 10in) - codes PXR31 and PXR36, four internal widths - from 3.05m (10ft 0in) to 4.88m (16ft 0in) - codes /030, /036, /043 and /049 together with nine lengths (i.e. code /073). The rear eaves height varies with the length of the garage.

Roller Shutter Doors

The main access is a continuous sheet curtain steel roller shutter door with a low maintenance, plastisol-coating (colour - brown). Manual chain operation is standard and electric operation is an option. Doors are available with clear heights of 2.5m (8ft 2in) for height code PXR31 garages or 3.0m (9ft 10in) for height code PXR36 garages. Clear widths vary.

Garage Support Structure

Premium Extra-High Garages have primed steel ïgoal postÍ style frames at 1.83m centres. Intermediate bay purlins and wall rails are cold-formed galvanised steel sections. Frame bolts are zinc plated.

Wall Panels

Heavy-duty, non-combustible, 1.98m (6ft 6in) high Compton Premium precast concrete panels with steel-reinforced vertical stiffening ribs at 300mm centres are finished externally with an applied spar aggregate. All connecting bolts and other fittings are rusting resistant. All external joints are sealed internally with mastic. A sand and cement fillet is installed to the internal perimeter of external walls. Above concrete panels in multibay blocks, partitions have fire-rated infill panels to maintain security in individual garages.

Applied Spar Aggregate Finish

This maintenance-free, attractive, multi-coloured spar finish harmonises well with surroundings. The spar is factory applied to the front face of concrete wall panels. Aggregate faced concrete samples are available on request for planning applications.

Roofing and Wall Cladding (above wall panels)

Box-profile, galvanised steel sheeting for roofing and wall cladding is finished externally with a low maintenance, plastisol-coating. In addition, all roof sheeting is finished internally with a ïGrafo-ThermÍ anti-condensation coating. All galvanised steel flashings have a brown plastisol finish giving a smart appearance.

Rainwater Disposal

Our standard specification includes the supply and fitting of a rainwater goods system. Black PVCu guttering is half round 112mm (41/2in approx) with stop ends and running outlet fitted to a brown plastisol steel eaves fascia. Black PVCu downpipes are 68mm (23/4in approx) diameter with discharge shoe at slab level.

Window, Rooflight and Personnel Door Options

Information on our full range of windows, wall-lights, personnel doors and other options is available on request.

Concrete Bases

Standard base detail drawings are available on request. The base slab (provided by others) should be 152mm (6in) larger than the external width and external length of garage size selected.To ensure building accuracy and alignment the base slab must be both flat and level.

Garage Layout Drawings and Calculations

As part of enquiry and order progress, standard plan and elevation drawings together with building detail drawings and structural calculations are available for Planning and Building Regulations approval if required.

How to Specify a Premium Extra-High Garage

We suggest you measure the height, width and length of your vehicle. Then assess what additional clearances are needed for roof racks, aerials, access and storage to establish the approximate size of garage required. Next, using the roller shutter door clear height and clear width tables on the right, select the minimum door opening size required. This establishes the practical building height and width codes for your garage. For further details, see the coded front elevation drawings. Using your required length, select the coded internal length from the table on the right. Where space permits, select from the standard range of red lengths. These have support frames at their maximum 1.83m (6ft 0in) spacing and hence offer the lowest cost per square metre. Alternatively, choose from the intermediate lengths that use a 0.61m (2ft 0in) increment.

Allow 1.1m (3ft 8in) for working space between the garage and fences, walls or boundaries.
