SPECIFICATION SHEET
Specification for VEGASCREEN®

DESCRIPTION
The external sun screen consists of a fabric roller blind that keeps out direct sunlight while partly maintaining the view.
The sun protection is placed on top of a closed structure, such as a rooflight.
With its elegant slim box, Vegascreen® perfectly suits the latest glass construction techniques and is an ideal match with all architectural styles.
Screen and motor are removable for installation, maintenance or, where needed, replacement.

INSTALLATION
The sun protection can be placed on a closed structure, such as a rooflight.
This system must be fitted to the window frame using feet. (for e.g. verandas, skylights, roof windows, etc. )
Our mounting feet are available in different heights and in two different types for conservatories with tubular or T-mullions.

DIMENSIONS
"This screen is suitable for dimensions of max. 4.50 m wide and max. 6.00 m high in 1 piece (surfaces of max. 27 m²).
Two screens with side channels can be joined together to a maximum width of 8.00 m."

BOX
The box is 230 mm wide and 140 mm high.
The box consists of a back cover with front and bottom covers attached to it by hinges.
These three profiles are made of extruded aluminium.
The sides of the box are fitted with aluminium end covers, which support the roller mechanism and are fitted with pins to insert the box into the side channels.

FABRIC ROLLER
The roller barrel with a flat fabric groove is made of ø85 mm galvanised steel with a wall thickness of ±1.25 mm.
In the fabric tube there is a motor tube that is part of the tensioning system.

FABRIC
"Polyester (with Pré-tensioned - method)
This type of fabric consists of a fine mesh with a fire-resistant PVC coating applied using the pre-tensioned method. (fire class M1/M2, depending on the colour).
The vertical borders are not welded. Top and bottom are high-frequency welded. "
"Rensonscreen® (with Rachel Trameur - method)
This type of fabric consists of a fine mesh with a fire-resistant PVC coating applied using the pre-tensioned method. (fire class M1/M2, depending on the colour).
The vertical borders are not welded. Top and bottom are high-frequency welded. "
All screens are made from one piece of fabric unless the height is > the width of the fabric roller. A welded horizontal seam (parallel with the box) is then needed.
With polyester fabric (according the Rachel Trameur - method or the ré-tensioned - method) the max. recommanded width is 4000 mm in one piece.
Weight polyester fabric (with Pré-tensioned - method) : ±380 to 420 g/m², thickness 0.43 to 0.45 mm.
Weight Rensonscreen® (with Rachel Trameur - method) : ±330 g/m², thickness ±0.40 mm.
Weight polyester blackout fabric (with Pré-tensioned - method) : ±650 g/m², thickness ±0,60 mm.
Weight Rensonscreen® Opaque (with Rachel Trameur - method) : ±470 g/m², thickness ±0.45 mm.
"Woven polyacrylic fabric
Often just called acrylic fabrics these are woven with polyacrylic yarn (polyacryl nitrate), coloured in bulk and are highly resistant to UV radiation. After weaving the fabric is subjected to a chemical treatment which makes it water and dirt repellent.
The fabric is woven in widths of approximately 120cm and is seamed all round and joined together by stitching. The widths of the seams and overlaps may vary depending on the fabric and the specific application."

TENSIONING SYSTEM
The system is tensioned using a permanently pretensioned belt. Pretensioning is achieved using leaf springs located on the motor barrel. The motor barrel is located in the fabric roller barrel. The number of springs ranges from 2 to 4 pieces, depending on the system width. There are belt pulleys on the left and right-hand sides of the fabric roller barrel. The belt starts on this pulley, is then routed across the alignment wheel into the lower chamber of the side channel, and across the pulley in the top chamber of the side channel to the bottom rail runner. The belt is looped around the runner.

SIDE CHANNELS
The side channels (67mm H x 41mm W) are made of extruded aluminium. This aluminium profile has a number of chambers in which the belt and pulley of the tensioning system are routed/housed. The lower chamber is neatly enclosed along the full length of the aluminium profile using a decorative strip. The side channels are installed on the window frame using mounting feet. The coupling side channel (67mm H x 84mm W) is also made of extruded aluminium.

BOTTOM RAIL
The bottom rail (42 mm W x 91 mm H) is made of extruded aluminium. The sides of this profile are fitted with a left and right trolley

GUIDE SYSTEM
This system guides the bottom rail and secures the box by means of pins in the end covers that fit into the hollow chambers of the side channels.

COLOUR
All visible aluminium profiles (box, side channels and bottom rail) are anodised (20micron) or powder-coated in the same RAL colour (60-80micron) as the external joinery.The end caps of Luran S type ASA polymer are also powder-coated in the same RAL colour (60-80 micron) as the external joinery. If all visible aluminium profiles are anodised, the end capes are powder-coated in RAL MAT 9006.

ASSEMBLY
All items are secured using stainless steel screws.

WIND CLASS
"This screen meets European standard EN13561 ( wind resistance class 3)
"

STANDARDS AND CERTIFICATES
This product is manufactured according to, complies with and/or has been tested according to:
EN 13561

OPERATION
"Electrical: using a 230 VAC tubular motor, without manual override.
The connection is included in the sun protection set.
The power supply and all wiring are included in the electrical set."

POWER SUPPLY AND WIRING
The power supplies up to the relay boxes are included in the electrical set in accordance with the wiring diagram provided by the supplier. Wiring is provided from the relay boxes to each motor, including control switches and automatic actuators with measuring devices. The electrician will also fit a junction box to each motor for later connection of the motor cable by the sun screen installer. If sufficiently long, the motor cable can be connected directly without a junction box.
