Our Skyline Box range of glazing bars offer an economical roof glazing solution when compared with curtain walling roofing systems. The glazing bar's strength is provided by an internal box section. The glazing bar is weathered by a screw on pressure cap (PC1) with a choice of plain (PC2) or ornate (PC3) cosmetic outer snap-on cappings to conceal all fixing screws.

When used with high performance double glazing units with warm edge spacer bars and argon gas filling this system can achieve an overall U Value of 1.4W/ m²K to comply with Building Regulation Document L.

Our Skyline range of glazing bars offer an economical roof glazing solution incorporating slim sightlines. The glazing bar's strength is provided by an internal stalk (or fin) which is cut away at the top and bottom main fixing positions.
An internal snap-on ornate capping system (PC4) is also available if desired to fully conceal the internal stalk giving the appearance of a feature timber rafter.

When used with high performance double glazing units with warm edge spacer bars and argon gas filling this system can achieve an overall U Value of 1.4W/ m²K to comply with Building Regulation Document L.

Timber rafters (supplied by the builder or joinery sub-contractor) will create an appealing visual effect inside any home and are totally protected from the effects of weathering by our externally clad Rafterline Patent Glazing system.
Due to the pleasing aesthetics of aluminium and timber materials our Rafterline system is the most popular specifiers choice for domestic projects.

When used with double glazing and thermal breaks this system is easily capable of providing an overall U Value of 1.6W/ m²K to comply with Building Regulation Document L.

Our Traditional patent glazing system remains our customers most popular choice for use on unheated spaces such as Railway Stations, glazed canopies and covered ways where thermal properties are not a consideration.
This system has been installed on thousands of projects nationwide and is available with a choice of capping systems to suit your needs.
A truly great glazing system combined with economy and a proven track record. 30,000m² of this glazing system has been installed by us on many major railway stations throughout the UK in recent times.

This system is capable of accommodating solid or multi-wall polycarbonate sheets or double glazed units up to 28mm thick if used on unheated spaces or where compliance with Building Regulations Document L are not a consideration.

Our 'Heritage' Patent Glazing Bar range is truly unique amongst roof glazing systems; there are no alternative products available on the market which can match an original lead covered steel patent glazing bar which originates from the Victorian era. This range has been manufactured by us unaltered for over a century and is the perfect product for listed buildings and for use in the refurbishment of significant and historic buildings. This system is also still very popular for new build projects and should not to be overlooked on today's modern buildings where a unique character look is desired.


The most popular way to protect our aluminium sections from oxidisation and create an appealing aesthetic look is to apply a polyester powder coated finish. This is a high quality finish and will perform admirably for decades as long as a regular cleaning schedule is maintained.
All of our glazing systems are coated after full manufacture so we do not charge you extra for choosing any of the very many standard colours available.

  • RAL Colour Chart

If you require a colour swatch then these are supplied free to Architects and Specifiers. Please click << HERE >> to visit Syntha Pulvin's web site where they are available to order on their contact page.

Coloured aluminium sample panels are also available for a small charge from the Syntha Pulvin web site. Click << HERE >> to request one of these to be forwarded to you.

If you are unable to obtain a colour swatch directly from Syntha Pulvin then help is at hand. We carry a small stock of swatches at all times but unfortunatley we are unable to provide these free of charge. Please forward a cheque for £6.50 which covers postage and packaging and we'll send one of these to you immediately.




Please note that not all of the colours shown on the colour swatch will be available from us as standard on small sized contracts while others may be obtained for a small additional charge. Please contact us with your requirements at order stage to determine if your chosen colour is available without additional charges.

We are able to offer most of our glazing systems in a dual colour format. Domestic customers regulary desire a white or other light colour internally to blend in with the internal decoration of the room whereas a darker colour, usually one of the many grey shades or black is chosen for the external colour finish. This has an additional cost of up to £150.00 depending on the project size.

Metallic finishes are available at premium rates but we will only usually supply silver (RAL 9006 and RAL 9007) due to the others generally being made to order for larger sized contracts.

The colours shown on the colour chart on the next tab button should be used as a guide only. Colours will vary depending on the type of viewing equipment or printer used. If you have any concerns then please order a colour swatch. (see above for ordering information)
