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.

 


A joint venture by the Patent Glazing Contractors Association and Pilkington Glass Ltd was organised to test the heat resistance of patent glazing when subjected to smoke temperatures.

This test was carried out at Warrington Fire Research Centre and produced the following results...............

FIRE RATINGS
All of our sloping patent glazing systems have a designation AA as defined in BS 476: Part 3 when they are installed with an infill such as 6mm wired cast glass or other glasses of at least 4mm thick.

If elements of the structure have need for a level of fire resistance when tested in accordance with BS 476: Parts 20 and 22, certain types of patent glazing will be suitable. These may either be tested or approved as 'deemed to satisfy' by fire authorities or local authority building inspectors.

A joint venture by the Patent Glazing Contractors Association and Pilkington Glass Ltd was organised to test the heat resistance of patent glazing when subjected to smoke temperatures. This test was carried out at Warrington Fire Research Centre and produced the following results.

The test sequence attempted the following furnace temperatures:

1. 300°C for 30 minutes
2. 400°C for 15 minutes
3. 500°C for 15 minutes
4. 600°C for 30 minutes

The results demonstrated that all aluminium and lead covered steel (Heritage) glazing bars should perform adequately at smoke temperatures up to 600°C. Laminated glass of nominal 6.4mm thickness remained intact up to 400°C and toughened glass of nominal 6mm thickness remained intact at 600°C.
