As our most advanced and thermally efficient solution, the 4Edge Pro system secures infill materials on all four sides using unique dry-sealed transom mullions. This cutting-edge solution provides superior weatherability, sleek sightlines, and hidden fixings. It merges the best features of roof-lighting solutions with the strength and span capabilities of curtain walling.
The 4Edge Pro eliminates the need for additional weathering tapes or silicone sealants, protecting the system from the effects of poor seals and environmental damage. Its innovative design significantly extends durability when compared to alternative sloping solutions.
Available in single, double or triple glazing configurations, the system is highly adaptable.
Fully compatible with our Skyline Box, Skyline, Rafterline and Traditional glazing bars, it is ideal for creating an appealing visual effect in both modern and traditional architectural projects. This next-generation system sets new standards in structural timber roof solutions by combining advanced technology with long-term durability and unparalleled flexibility.
Our 4Edge Pro glazing system stands out as a superior weatherproof solution compared to traditional sloping curtain walling systems. The internal box section of the glazing bar delivers exceptional strength, while the screw-on pressure cap ensures robust weathering. For a seamless aesthetic in modern roof glazing, you can choose from plain or ornate snap-on cappings that conceal all fixings.
When combined with high-performance double glazing units featuring warm edge spacer bars and argon gas filling, the 4Edge Pro system achieves an impressive overall U Value of 1.35 W/m²K, fully compliant with Building Regulation Document L.
For even greater thermal efficiency, the 4Edge Pro system used with high-performance triple glazing units, warm edge spacer bars and argon gas filling can reach an outstanding overall U Value of 0.95 W/m²K, also meeting the requirements of Building Regulation Document L.
Experience the ultimate in weatherproofing and energy efficiency with the 4Edge Pro glazing system.

Performance Data for 4Edge Pro incorporating Skyline Box patent glazing bars.
The glazing bar spans shown above are based on using 6mm thick glass for the double glazed, single glazed and canopy types and the bars being spaced at 600mm centres. We will select the appropriate glazing bar for each contract. Spans are dependent upon the site location and exposure rating, site altitude, distance from the sea, height of glazing from ground level, shape of the roof, pitch of glazing, glazing bar centres, glass weight, wind speeds, snow load, dead load and maintenance loads.
* The above spans for each glazing bar have two values. The lower span values are calculated using the most extreme environmental loadings possible in the UK whereas the higher span values are based on the least extreme. Due to the wide range of these values it is therefore essential that we are supplied with the site postal code to enable us to calculate the correct glazing bar type for every project. There are a large number of variables which are used to determine the maximum span of the glazing bars so please do not attempt to buy any glazing bar materials from us without first allowing us to carry out the necessary calculations for your project.
