Claimed to save up to 25% of energy costs compared to conventional sheets, Bayer Sheet Europe’s Makrolon multi uv 4-wall sheets are suitable for tunnel-shaped roofs, industrial buildings, sports facilities, greenhouses and swimming pools. The translucent construction material is 8mm thick and has a heat transfer coefficient of 2.76 W/m2K. The low weight sheets can be easily installed on large surfaces with light substructures and, thanks to their cold bending properties, they can be used on tunnel shaped roofs.

Finnjoist, the fully engineered I-joist from Finnforest, has been incorporated into Donaldson Timber Engineering's new structural insulated roofing system.
Fully TRADA certified and NHBC approved, the insulated panel construction enables safety and time savings as well as affording low u-values. It does not require purlins, while its design and loading performance offers no length restrictions.
It has already been trialled by Persimmon who found that the roof could be assembled and installed on a two-storey house in one day.

Flag UK has launched a new copper roofing membrane that contains real copper, enabling it to age in the same way as the actual metal.
Perfect for that traditional look, Copper Art contains particles that form an integral part of the membrane resulting in long term stability of colour. The metallic membranes are available with decorative profiles to replicate the traditional folded metal joint or standing seam profile.

Established in Europe for 40 years, Marley Waterproofing has introduced its Uniply pvc roofing membrane into the UK.
The membrane features a polyester reinforcement that provides excellent mechanical properties and performance characteristics, the company claims. This allows for wider rolls and reduces the number of fixings, which should help achieve a rapid and simple installation.
The reinforcement mesh is extremely flat, which means that the lower polymer layer will also be flat and evenly distributed. It is protected by a uv-stabilised layer of pvc, prolonging the service life of the membrane.
Uniply pvc will form a clear, uniform finish on all types of flat roof, whether mechanically secured or fully adhered. It is also suitable for podium roofs and terraces.
