ALU vs. PVC slats

aluminium slats

The all-aluminum roller shutters offer optimal sound insulation and enhanced security. Aesthetically, the choice of colours is extensive and the finish is effectively resistant to UV and weather wear.

  • Visible dimensions of aluminum slat: 42 x 8.80mm; weight = 2.31Kg/m2

  • Polyurethane foam injected: density 90kg/m3

  • Additional thermal resistance (?R Class 4) = 0.15 m2 K/W

  • Thick aluminum strap 27/100e

  • Crimped slat ends to wedge the alignment of the slats between them; slats are protected during operation, and quieter

PVC slat

PVC slats have high thermal insulation while the material is a more economical option. The material is sensitive to UV and bad weather, and colour fading, especially white. PVC slats are always associated with an aluminum frame, ie box, side guide tracks and bottom slat.

    • Visible dimensions of PVC slat: 39 x 8.20mm (weight = 2.82Kg/m2)

Test colour options at home!

Order free samples of made-to-measure shutter slats in white RAL 9010, beige, anthracite gray RAL 7016, light gray RAL 7038, brown RAL 8019, black RAL 9005 and imitation gold oak wood veneer. Find them in the dedicated SAMPLE tab.

Slat apertures for good ventilation

The AvosDim roller shutter curtain has apertures between the slats. These are regular openings / interstices which allow ventilation with lowered (not fully closed) shutters, or to darken without obscuring light completely.

When completely closed the shutters offer a full blackout.

Shutter curtain clips

Shutter slat curtains are attached to the roller tube with flexible curtain clips as standard. These are space-saving, flexible and hold up very well to multiple daily operations. Depending on the control type selected, rigid hanger clips, also called anti-lift clips, are also available. These rigid clips prevent the shutter from being pryed up from underneath for absolute security.

Installation of the Tunnel shutter

Total width of the Tunnel box including side panels = transom width + 200mm (the box & side panels assembly protrudes by 100mm at each end of the transom)
A free space of at least 60mm on each side of the box for concrete filling is recommended. Any doubt? Ask us for advice or ask your builder!

Are you ordering the shutter and its mechanism without the box? Here is additional information about what we will make for you:

  • Height of the slides = height between walls + 100mm

  • Height of slat deck = height between walls + 126mm

Motor control options:

switch control roller shutter

Switch control motorised shutter - AvosDim ® motor

This electric roller shutter can be operated effortlessly from a hard-wired switch of AvosDim or any other brand. Both the motor (4-core cable) and the switch require an electrical connection. The stop limit switches of the wired motor are manual. The costs for this control type are very affordable. AvosDim ® Motors also exist with a 'manual override' version. The emergency manual override motors allow manual operation without power supply via a crank.

Remote control motorised shutter - AvosDim ® or Somfy ® RTS motor

Automated opening and closing groups can be made from the same control unit. Signal ranges easily allow remote management over several meters.
Thanks to the AvosDim ® smart home box or Tahoma Somfy ® connected home box, unidirectional RF roller shutter motors can also be managed from the smartphone app on Iphone and Android, as well as via Alexa or Google Assistant / Google Home voice speakers. Home automation boxes for shutters are sold separately.

AvosDim ® Motors also exist with a 'manual override' version. The emergency manual override motors allow manual operation without power supply via a crank.

Motor stop limits are adjusted in the factory, however occasionally these need to be re-set on installation.
