PRESYSTEM integrated window system for sunshades

The integrated window system for sun protection systems with louvres, which interprets the latest architectural trends.

  • Reducing thermal dispersion
  • Perfect soundproofing
  • Versatility right from the design stage


The strictest standards

Excellent thermal and acoustic performances suggest the adoption of the PRESYSTEM® SPF integrated window system for sunshades even in critical situations or for very high standard certifications, such as CasaClima Gold or Passivhaus for thermal insulation or Class 1 UNI 11367 for sound insulation. The insulated side shoulders of the PRESYSTEM® range are here associated with a specially shaped high density shutter box for sunshades. It can be completed with a thermal cut under the window sill to maximise the degree of insulation.

Also made to measure

PRESYSTEM® SPF is designed for housing various models of sunshades and comes in many variations depending on the type of wall and the position of the window frame. Alpac also provides complete technical and design assistance to develop ad hoc models, depending on the specific needs of the building site.

With adjustable slats in pre-painted aluminium alloy. The slats are strengthened by longitudinal edges at the ends, with a light-proof gasket and a self-supporting sliding guide with roller chain movement. The MOD is also available. A100 SICUR, with a 14/10 thick extruded aluminium slat, for even greater security against theft and burglary.

With adjustable pre-painted aluminium alloy slats. The slats, fitted with a noise damping gasket, are connected to each other by the orientation device consisting of a braid of polystyrene-coated carbon fibre wires. Non-self-supporting guides.

Wellness comes from practicality

Alpac offers a wide range of motors for moving roller shutters and sunshades, all coming with the main international type-approvals.

The Alpac motor drives with radio technology are designed and built to ensure minimum installation times and costs, as well as maximum user comfort. Thanks to the integration with domotics, it is possible to control every single roller shutter or the entire group via an app for smartphones, or a centralised display, also scheduling openings and closings based on pre-set days and times.
