Hermes Cassette Boxes

Hermes is the Son of Zeus.   For this reason, you can expect every element of the Hermes roof blind to look identical to the Zeus blind. However, it is not as powerful but still adequate to make the fabric look good within its’ limitations depending on fabric choices.  It still boasts a symmetrical look with easy to clean cassette boxes at both ends. Inside the cassette boxes, the engineering brilliance of the Hermes Electric Roof lantern blind is hidden away from dust, flies and view allowing it to blend into your lantern’s upstand. (White is standard but any RAL colour can be offered)

At one end of your Hermes, Large roof blind is the 110mm² cassette headbox. This conceals the 80mm motor tube and has sufficient room for 3.25m of fabric to wrap around it. Unlike pleated blind systems that concertina at one end gathering dust, your chosen Hermes fabric is always protected when not in use. At the other end of your blind is the 110mm² tension box. This contains two tension springs that provide the power to keep your chosen fabric taut via hidden white nylon cords.

These constant tension springs average a combined tension of 10kg, however, these springs lose power as the fabric is deployed from a combined 13.4kg to 8.4kg.  The Hermes offers a good fabric finish without visible cords for wider and longer lanterns which would not be achieved with smaller roof blind systems.  However when considering heavier fabrics (such as blackout) on lanterns nearing the limits of the Hermes capabilities then the Zeus may be a better option.  Make an appointment to discuss further with the WindowTreat electric roof lantern blind specialists

Hermes Side Channels & Shelving

The Hermes electric roof lantern blind has slimline side channels 28mm wide supported by the 50mm shelving. They play an integral part in the ‘no visible wires’ Hermes electric roof lantern blind system as the 1.5mm nylon cord used to withstand the power of the 5kg tension springs are hidden inside both side channels. The zipper ribbon technology is welded to the edges of your chosen blind fabric creating a very strong join. The zipper ribbon is securely held and prevented from being pulled out of the channels. It allows the blind to run freely and quietly along these channels whilst returning the fabric squarely onto the motor tube every time it is used.

The shelving is a critical part of the Hermes roof blind system. The powder-coated L-angle profiles allow the electric roof lantern bind to sit squarely within your opening even when your lantern opening is not truly square (after the final skim your lanterns opening is rarely truly square) It also ensures there is no light ingress around the sides. The shelving at both ends is 220mm in depth. This allows the heavy-duty hem bar to disappear above the shelf at both ends keeping a uniform look with just the fabric on show. The side shelving supporting the systems side channels are a slim 50mm.

Hermes Hem Bar & Crush Brush

The Hermes aerodynamic heavy-duty 75mm hem bar has been designed to perform not simply look good. The heavy-duty hem bar has excellent fixing points with the fabric and can withstand the power being produced by the Hermes tension springs. Lesser hem bars used at this size would risk bowing under their weight, bending under the forces or simply being ripped from the fabric. Its rigidity contributes to the final cloth finish.

The grey fussy brush on the end of Hermes’s heavy-duty hem is also known as the Crush Brush. It creates a seal between the hem bar and the tension box when your blind is closed. It also allows it to close quietly to avoid the sound of metal on metal. Grey is standard but sometimes black is used when maximising room darkening. White is only permitted when using a white screen fabric as it lets considerably more light transmit through it.

Hermes SOMFY Motors

Not all SOMFY motors are equal and can be used in our specialised roof blinds. Due to the power created by the Hermes Large electric roof blind, only a motor with sufficient torque can be selected. This allows your blind to defy gravity and travel horizontally at a controlled speed whilst maintaining tension on the fabric.

The Hermes Electric Roof Lantern blind uses a SOMFY Radio Transmitted Signal (RTS) motor as standard. This allows you to control your blind using a remote-control handset or remote-control wall-switch. The Hermes SOMFY RTS motor is compatible with the SOMFY Tahoma Switch which offers a simple gateway to smart living.

Alternatively, hardwired Somfy motors can be used on request which will allow compatibility with existing home automation systems such as Lightwave, Control-4 & Luxon

Touch Control (Radio Technology RTS)

The standard Somfy motors for the large Hermes electric roof blinds use radio technology.  This enables you to have a choice between a remote handset or a wireless wall switch included in your investment

A simple press of a button on your chosen remote control device sends out a radio wave signal to operate your roof lantern blind.  You don’t even need to point the handset at your roof blind.  The radio waves are omnidirectional and operate to a range of over 15 metres in any direction.  

Somfy radio technology utilizes a rolling code with 16 million combinations to ensure that RTS communication is both safe and secure.    This ensures that your controls will not interfere with other radio-controlled products in your home or adjoining neighbours.
