The Unlimited One is a true masterpiece of daylight design. With the cleverly engineered gutter/beam connector system, the Unlimited One lets you build long rooflights as far as the eye can see. The Unlimited One lets you combine multiple different sizes and shapes together for a design that is truly distinctive and truly your own. You can bring the Long Slim One, the Rectangular One or the Square One together in any combination.

This is the ideal solution for covering a roof opening that exceeds the maximum span our a singular unit, which is limited to 3-4 m2 of glass. The Unlimited One can be customised to cover almost any desired roof opening.

The Unlimited modules:

  • Can span a maximum length of 1500 mm and width of 3000 mm
  • Can be combined into huge spans of liberating daylight
  • Can be easier to handle than a 4 m2 singular unit
  • Are combined by an advanced connector system
  • Are separated by a slim (126 mm) beam which can be flexibly positioned to fit both your interior and exterior architecture

Finally, The Unlimited One is also a great value for money product, priced below the same size of a singular unit.

Glazing
Glazing

Our insulated glazing units offer you the option of double glazing or triple glazing units for your rooflight. Choose double glazing for the maximum daylight drenching effect or triple glazing if superior energy saving eco credentials are your priority.

All our Unlimited glazing units:

  • Come with a laminated inner pane, which we consider a prerequisite for safety measures 
  • Use three different glazing constructions to ensure the best quality and durability for our larger glazing units
  • Have warm edge spacers to ensure a thermal breakage and energy efficiency
  • Come with a 115 mm black silk screen to protect the underlying gasket system and for aesthetic purposes
  • Have a reduced 57.5 mm silk screen between the modules, in order to ensure a consistent exterior aesthetic 

As an example, our triple glazing has a LowE coating with a superior insulating value of Ug 0.5 and a light transmittance of 71%. We use an 8 mm toughened outer pane and a 12.76 mm (66.2) laminated inner pane, separated by two argon gas fillings for thermal performance. See all the specific values of our glazing constructions in our glazing table.

Frame Construction

All our lightweight aluminium rooflight frames are:

  • Designed to work perfectly with our laminated insulating glazing units
  • Crafted from highly durable and strong 5 mm aluminium, selected for its high corrosion resistance, joint strength and malleability
  • Hand-welded on the inside of the corner sections to ensure a smooth surface and a completely seamless connection
  • Treated with a polyester powder coating to ensure a tough, weather and corrosion resistant, durable finish
  • Powder coated with our standard RAL 9005 Jet Black
  • Can be customised through a variety of special colours

We have constructed specific aluminium frames for our double glazing units and our triple glazing units, to ensure that the pane is positioned as low as possible in the construction, which ensures an ultimate insulating value for the rooflight.

Upstand
Upstand

The upstand for our Unlimited One has an advanced connector system with male/female connections. This ensures a slim combi-installation possibility, with a mere 126 mm wide aesthetically pleasing beam spanning the visible area between units.

Our upstands come with:

  • A superior pre-fitted gasket system, ensuring a 100% tight and secure connection between the frame and upstand construction
  • A pre-installed vapour barrier, which ensures a safe and easy connection to the roof itself
  • An internal surface treated with a membrane of water based white coating (RAL 9010) on the waterproof plywood
  • An external surface of untreated waterproof plywood, which is great for applying roofing felt or other flat roofing materials

Our upstands come in 150 mm and 300 mm, depending on project requirements and architectural specifications. 

For customised upstand heights, please contact us.

Performance
Performance

As all Vario rooflights are bespoke products and individually made to order, the Declaration of Performance [DoP] will be unique for each roof window. Some of the essential characteristics will be based on product type, size and variant you choose for your long window. The specific DoP will be generated through our online DoP configurator, for each individual product. 

If you would like to request a specific DoP, please contact us.

Opening
Opening

Our Unlimited One can be designed to freely combine fixed and opening modules in any configuration, for instance you can put two or more opening modules next to each other. In our opening rooflights, the chain actuator is fully integrated in the wooden upstand. The actuator is not visible from the inside when the roof window is closed, thus there is no visual difference between fixed and opening rooflights.

A module with motorised ventilation is operated by either one or two actuators, depending on the clear internal area and the width of the window:

  • A double glazing rooflight needs two actuators if the product is larger than 2 m2 or has a width wider than 2000 mm
  • A triple glazing rooflights needs two actuators for a product which is larger that 1.5 m2 or has a width wider than 2000 mm

The Tech Stuff:

  • The actuator uses 3 amp and must be controlled by a separate OS ± 24V system
  • In the OS ± 24 V, the actuators are controlled by ± 24 V DC 
  • For the OS ± 24V, the actuators, control units and switches are supplied by Vario
  • For two actuators, there will be a need for a larger control unit, which will be supplied by Vario
  • The actuator can be integrated in common building automation fieldbus systems, e.g. KNX, BACnet, LON and Modbus, through the integrated MotorLink™ technology. Connection to a fieldbus system requires a separate control box between fieldbus system and actuator
