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 following performance data tables show the different glass types available to provide you with your desired levels of light transmission, solar radiant heat transmission and shading coefficient values.


 

 
  • Body Tinted Solar Control glass
  • Coated Solar Contol glass ~ Normal lead-in times
  • Coated Solar Control glass ~ Extended lead-in times
   

The table opposite shows performance data relating to the most common solar control glasses available on the market.

The values are based on double glazed units incorporating inner panes of 6mm low e clear glass and the outer pane is as show in the table.

The first two items show information pertaing to clear glass (without solar control) to aid in comparison to the other products.

Even clear glass in a low e double glazed unit (which most people believe allows 100% of light through) actually blocks 22% of visible light from entering the building. This is worth bearing in mind when considering the correct product for your solar control requirements.

The table opposite shows performance data relating to high performance neutral solar control glasses available on the market with normal lead-in times

The values are based on double glazed units incorporating inner panes of 6mm clear glass and the outer pane is as show in the table which has a low e coating incorporated into the glass.

These glasses are popular due to high light transmission values combined with a neutral tint rather than the body tinted coloured glasses available.

The table opposite shows performance data relating to Pilkington high performance neutral solar control glasses.

The Suncool range is available in many different formats but is rarely used in roof glazing as the lead-in times for these products are usually unrealistic compared to the Sunguard Super Neutral range which is readily available in the UK.

Lead-in periods are usually 8 weeks or longer so very carerful planning with the programming of the project must be considered to enable these products to be used.

The values are based on double glazed units incorporating inner panes of 6mm clear glass and the outer pane is as show in the table which has a low e coating incorporated into the glass.

These glasses are desirable due to high light transmission values combined with a neutral tint rather than the body tinted coloured glasses available. Suncool is also available with a range of coloured coatings for aesthetic purposes.
