Façade Louvre Blade – Residential Glass (FLB-RG)

Product features and details.

Façade Louvre Blade (FLB-RG) Description

Mounted in façades and end of corridors, Façade Louvre Blade – Residential Glass (FLB-RG) smoke vents exhaust smoke and heat from a building allowing escape routes to be kept clear of smoke and are fully certified to BS EN12101-2. They may also offer inlet air and comfort ventilation. They are available in a wide range of louvre glazing options and control systems and are particularly suited to apartment and commercial buildings. They are fitted with an anti-trapping actuator providing protection from injury and offer a high resistance to weather and are therefore suited for use on exposed and high wind areas. They provide good security and do not create a fall hazard when open.

The FLB-RG louvre incorporates a thermally broken aluminium framework. The frame sections are 40mm wide and 77mm deep, with mitre joints and are manufactured from thermally broken aluminium. All aluminium is polyester powder coated to a standard RAL colour. Glazing options include a 30mm thick toughened inner/ laminated outer double glazed blades with argon filled cavity and warm edge spacer; or triple glazed for increased U-value.

Alternatively they are available as solid insulated blades which may be mill finish aluminium or powder coated to any RAL colour. They are installed vertically and available with a wide range of adaptors for installation into refurbishment situations as well as new build.

The actuators are 24V DC, 1.2 Amps and mounted on the internal top right hand and have a traction force of 1400N and with an IP20 protection rating. They are supplied as standard with built in anti-trapping feature for protection against injury. They consume minimal energy during opening and closing.

Can the FLB-RG be installed in any orientation?

The FLB-RG is strictly designed for vertical installation only and cannot be installed at any angles, pitches, or horizontally.

Can the FLB-RG be used for mechanical extraction?

Yes, the FLB-RG is suitable for mechanical extraction.

What type of blade infill is used in the FLB-RG aluminium blades?

We now use Mineral Wool as the infill for the FLB-RG aluminium blades.

What is the minimum height required for installing motors with an anti-trap function?

The minimum height for the AOV to accommodate the anti-trap motor is 538mm.

Is it possible to have an FLB-RG with a manual lever instead of an electric one?

Yes, a manual lever can be installed, but this is only advisable for environmental ventilation schemes, not for smoke ventilation.

Can the FLB-RG have a restrictive opening for environmental mode?

Yes, a restrictive opening is possible and can be configured through certain companies’ control systems; we can verify this.

What is the standard RAL finish for the FLB-RG?

The standard finish is 30% gloss (matte), coated at 60-80 microns, and it comes with a marine coating.

Is external access needed for servicing the motor?

We do not install manual hand levers or motors externally due to weather and potential misuse. However, external servicing can be facilitated if the customer installs a 50x20x2 angle bracket flush to the outside of the frame with predrilled holes. This setup allows for the vent to be installed outside while the motor remains inside, but ensure there is sufficient cable length for tilting the vent to prevent unauthorised entry into the building.

Can the FLB-RG be installed in doors?

The FLB-RG has not been tested for door installations and should not be combined with doors. It needs to be installed true and square, which cannot be guaranteed with doors since they are typically hung at an angle to close automatically, potentially affecting the vents functionality.

Does the FLB-RG comply with the PAS24 security rating?

The FLB-RG does not have a PAS24 security/anti-burglary rating, as this rating generally pertains to doors and windows, not AOVs.

Can the FLB-RG incorporate environmental trickle vents in the frame?

In a smoke scenario, all other levels should remain closed to prevent smoke re-entry. While it is possible to open trickle vents slightly for background ventilation, we recommend using our Network Controls to automate this process on a timer. In the event of an alarm, the fire floor will open, and all other floors will receive a ‘close’ command.

Can the FLB-RG be supplied without glass?

Yes, the FLB-RG can be supplied without glass. In this case, the glass will be provided by others and delivered to our supplier for installation.

Can the FLB-RG be supplied with a bird or steel mesh?

Currently, it is not possible to supply the FLB-RG with a bird or steel mesh.

Has the FLB-RG been sound reduction tested?

The standard Lam/Lam design has not undergone sound reduction testing. However, we do offer sound reduction tested blade combinations, such as Float/Lam-Silence or Aluminium Panels.

Is it possible to have the FLB-RG in shapes other than square or rectangular?

No, the FLB-RG is not available in any shapes other than square or rectangular.

Does the FLB-RG come with reverse polarity?

Yes, our standard 24V motors are equipped with reverse polarity as a standard feature.

Is a 230V motor possible for the FLB-RG?

Yes, a 230V motor is available, but please note that this option does not include the anti-trap function.
