There are 10 models of Velux® skylights to choose from, and a range of glazing and flashing options to get the perfect skylight matched. 

MOST people will immediately relate to ALUCOBOND, one of the most established and best selling aluminium composite panels in the world, developed some 35 years ago and successfully used under all climatic conditions on five continents.
Now from Alcan Composites, the company that developed ALUCOBOND, comes ALUCORE which is already being widely used in many countries around the world.

ALUCORE is manufactured by Alcan Singen GmbH in Germany using the same proven technology as applied in the production of ALUCOBOND. The highly rigid and light panel consists of two skins of aluminium alloy bonded in a continuous production process to a core of aluminium honeycomb. The viscoplastic adhesive used results in a better peel strength which enables post-forming. For example, ALUCORE can be curved using conventional pyramid rollers. The manufacturers believe that no other honeycomb panel can be shaped so easily.









The difference between ALUCOBOND and ALUCORE lies in the weight and rigidity. For example, if composite panels are chosen because of their flatness, ALUCOBOND is an excellent choice for modular panels in sizes up to 1250 x 3000 mm. However, for bigger panels, ALUCORE will be a better choice. With its much higher rigidity and strength, it is possible to have larger panel sizes, up to 1500 x 6000 mm, without the need for stiffeners.







ALUCORE is also an excellent material for linkway and shelter applications. As a result of the product’s light weight and excellent strength, large exterior ceilings and roofs constructed from ALUCORE, are flat and do not sag, even after many years of exposure to wind and external weather conditions.















The proven paint finish is another valuable characteristic of ALUCORE. The skins are coil-coated with high quality paint, prior to lamination into a composite panel. There are 30 available PVDF stand- ard colours to choose from, for exterior applications. For larger quantities, panels with special colours and finishes can also be supplied. These include decorative foil applications (wood, stone, etc).










Like in the case of ALUCOBOND, ALUCORE is not sold over the counter. For every application, the product is tailored to suit the specific requirements of the client’s project. ]]> Mon, 03 Nov 2008 04:54:09 +0100 http://www.rfaguide.com//index.php?option=com_content&view=article&id=96:techzone-ceiling-system&catid=55:roof&directory=220

Falzonal® utilizes an aluminium alloy chosen in a special temper (A1 Mg1/AA 3005, H 41) and is designed for extreme malleability by roll forming onsite or using the installation artisans’ hand tools.

The company, Novelis Deutschland GmbH (formerly known as ALCAN), has the know-how for the adhesion of the paint on the aluminium substrate, as well as the unique UV-resistant paint. This ‘marriage’ between the 0.7mm thick core material aluminium and the 25 micron-thick painted surface comes via the continuous process of subsequent degreasing, chromating and primering. The final curing of the paint is done in an oven at 240 degrees Celsius.

 
Available in 38 standard colours, Falzonal® coils come with a UV-resistant protective film which incorporates an anti-slip feature for safer installation on wet slopes and is symmetrically perforated for easier and quicker lockseaming. Novelis designed Falzonal® to meet extreme conditions of endurance, functionality and life-long beauty of roof and wall claddings worldwide.

Green Paks are a fast and affordable way to own a green roof. They are changing the way such roofs are constructed, and are making these less expensive as well as easier to install. The product eliminates many problems typically associated with installing a green roof. Green Paks are self contained modules pre-packed with engineered soil; specifically formulated for rooftop plant growth; and can be stored for long periods of time prior to the start of a green roof project. They remain mobile after planting, allowing the modules to be easily moved if roof repairs or alterations become necessary. Each module covers 5.2 square feet of roof area. They are made from specially woven fabric knitted of high density polyethylene. Packaged as 42 modules per standard 48? x 42? pallet, 20 pallets per truck load, each pallet of Green Paks covers 218.4 square feet of roof area.

Eliminated is the need for dump truck loads of soil that are both difficult to hoist and to spread evenly across the rooftop. They can also be stored on the job-site indefinitely prior to installation and planting; and can be installed using a variety of manufactured geo-textile drainage products over any roofing material. Available with or without planting service, Green Paks allow landscape architects and contractors alike their space for artistic expression.

Traditional panels might require expensive and heavy fixing structures to attach them to the roof. This system from Nu-lok simply locks the panels into the existing battens to provide a safe power source, which seamlessly integrates into the existing roof.

Nu-lok’s existing patented fixing system - which replaces traditional wooden battens with a lightweight, galvanised steel grid system - combines with specially designed solar PV (photovoltaic) panels.

Solar Photovoltaic (PV) panels work by converting solar energy into electricity. PV panels consist of one or two layers of a semi-conducting material, usually silicon. When light hits the solar PV panels on the roof, it creates an electrical field across the layers, thus generating electricity. This powers all appliances and lighting, much the way electricity from a mains supply does.

Nu-lok solar roof claims the following benefits:

• A dedicated, clean, safe power source
• Reduced electricity bills; and protection against rising energy costs
• Reduced carbon dioxide emissions; increased property value
• Minimal maintenance with long operational life
• No moving parts - silent operation Seamless integration with an existing roof
 
Not only is the environment set to benefit from an ongoing reduction in CO2 emissions, immediate financial savings are made by eliminating the need for expensive and unsightly support housings.

Nu-lok’s founder Bob Hick explains: “We were surprised to discover that people don’t realise the manufacture of support carriages for solar panels actually creates additional CO2 emissions. These emissions extend the time needed to obtain a positive return from your investment in solar panels.

“Nu-lok is pleased to offer a solar roofing solution that not only looks fantastic, but really does keep CO2 emissions to an absolute minimum,” Hick explained.

Nu-lok’s system doesn’t require any nails or screws, which means installation costs are significantly reduced and panels can be easily removed or replaced. Extra panels can also be simply added to increase the amount of electricity generated.

Sarnafil was the first single-ply membrane manufacturer to label roofing products under the EPA’s

Energy Star Roof Products program in the USA. The program is a voluntary partnership between the EPA and a select group of roof product manufacturers. The focus of the program is to promote environmental and economic benefits of reflective roofing. As a Charter Partner of the program, Sarnafil’s EnergySmart Roof® has gained much attention in the media and wellknown research institutes.

Roof Wizard represents the latest and most powerful software currently available for roof modelling and estimating. The software features automatic roof modeling in full 3D, calculates all material and labour quantities, optimises sheet and off-cut usage and inserts information into any one of seven pre-defined reports.

Roof Wizards is also a breeze to learn. In fact one could be up and running after just a few hours, thanks to picture menus and text menus that use terms that one currently uses – no computer jargon. Roof Wizard allows the operator to try different options, and selects the best roof arrangement; it provides fast and accurate quotation; input is via simple point-and- click with a mouse; all forms are automatically filled and printed; graphical display for fast, accurate roof input.

The system allows the operator to setup definition files for all roofing materials from many manufacturers, estimated in the one simple system, total roof area, total length of ridge, hips, valleys and gable ends. All the variables are accounted for: sarking, caps, special finish, fixer’s rates etc. There are separate report forms for client, accounts, fixer and job supervisor.

Available are fully dimensioned 3D representation of any roof shape - multi-hips, skillion, gables, dormers, dutch gables, verandahs, atriums and two storey. All fixtures and fittings required by the roof plumber such as flashings, downpipes, clips and screws are also accounted for in the estimate.

It allows traditional welding and all methods of installation, in particular laying with standing seams and processing operations including bending, shearing, profiling, curving, etc. Ugitop enables the design of unified building envelopes: soffits, canopies, cladding, façades (flat fascias, ribbed profiles, cassettes, etc.) and roofing.

A wide range of components and accessories provides the finishing. It’s light weight, 3 or 4 kg/m2, facilitates laying on light roof frames, and due to its favourable coefficient of expansion, the strips laid reach 15 to 20 metres in a single length.

Specially designed for building and marketed by Ugine&Alz, Ugitop is offered in the form of coils, reels or sheets. Widths range from 250 to 1,250 mm, and thicknesses from 0.4 to 2 mm. It can be delivered film-coated to avoid marks and soiling during use.

Monier CoolRoof® acts as a solution to effective cooling. When a house is cooler, one feels more comfortable and the stress due to heat is minimised. Monier CoolRoof® also helps the body reach thermal neutrality, which means that a person feels neither too warm nor too cold. As a passive system, Monier CoolRoof® keeps running the entire day. When the house is cooler, airier, and fresher, one uses less air-conditioning; thus saving one’s electricity bills. Simply put, it is a natural and passive system to limit heat transfer through the roof.
