 The TPX System

Coxdome TPX are functional economical rooflights designed for a wide variety of applications. The range comprises of an extensive selection of rooflights designed specifically for refurbishment projects.

When non-standard sizes are encountered adaptor kerbs, with or without ventilation, can be ordered. These units are purpose made to the precise inner and outer dimensions of the existing kerb construction.

GRP insulated upstands, 150 mm high are available for circular based rooflights. These are complemented with circular based dome mouldings.

Tops only in all sizes and glazing types can be ordered if required.

Continuous version of the range are available. Purpose made side and end units can be site joined to produce almost any length. Insulated cross gutters are installed to span the aperture.

Features:

• The range offers two upstand heights, 175 and 270 mm, produced from galvanised flexible polyester coated steel finished in white.
• Choice of upstand height ensures that many thicknesses of roofing insulation can be accommodated whilst still maintaining adequate height above the finished roof level.
• Four choices of ventilation are available permanent, controllable, powered and hinged.
• Two insulation types can be specified - cork or mineral wool.

 Glazing:

• square / rectangular dome or pyramid profile.
• The glazing material options are single or double skin enhanced UV protected polycarbonate and cell cast acrylic.

 The Mark 5 System

The Coxdome Mark 5 was the first systemised approach to rooflights introduced in 1967 and has since been widely used throughout the world. A recently updated design for the glazing frame increases the security features inherent in the overall design. The use of a unique snap fixing continues the security theme but allows numerous permutations of ventilation and access units to be specified.

Ventilation Options:
All rooflights can incorporate the 'Hit and Miss', permanent, C/O50 or powered ventilation. They can also be specified as hinged rooflights with either power or mechanical operation.

Matrix Gutter System:
All the benefits of the standard and framed Coxdome Mark 5 rooflights are available for overglazing large open areas by using the Coxdome matrix system of structural aluminium gutters, which is compatible with propriety structural space frames.

Features:

• A selection of upstands and kerb adaptors for fitting to many different roofing systems are available.
• Produced from high quality aluminium extrusions precision welded in a large range of sizes.
• Framed pyramids are available in 30° or 45° pitches and can be tailor made in sizes up to 3000 mm square.

Glazing:

• Square / rectangular dome or pyramid profile.
• The glazing material options are single or double skin enhanced UV protected polycarbonate and cell cast acrylic.
• Glazing elements are available in clear, diffused and bronze tinted options.

The Galaxy System

The Galaxy rooflight offers a domed rooflight either single or double glazed which has a horizontal flange of 100 mm that enables the rooflight to be positioned over existing kerbs at varying dimensions and of varying width. 

In essence the Galaxy offers a much larger variation of dimension between the outside finished kerb and the inner face of the vertical leg of the moulding. Therefore many more existing rooflights can be replaced without the need for a kerb adaptor.
