Security roller shutters Aluprof

An exterior roller shutter is an aluminium shell that closes the whole window in one movement. At night and while you are away it works as protection against break-ins, in winter as an extra layer of insulation, in summer it keeps the room cool, and in a bedroom it gives complete darkness and quiet. We build our shutters on systems from the Polish group Aluprof — below we explain honestly how the systems differ and which one to choose for your house.

SK / SKE / SKP — surface-mounted, with a 45° or half-round box

The classic choice for a finished house: the shutter is not tied to the window, so it can be fitted at any time — onto the frame or straight onto the wall, without rebuilding the opening. The SK and SKE have a box with a 45° chamfer (on the SKE it is rigid extruded aluminium), while the SKP with its half-round box sits neatly back into a reveal and blends into the facade. Choose your curtain: foam-filled aluminium profiles PA 37–55 with two-coat PU/PA lacquer, extruded PE 41 and PE 55 of higher rigidity, or lightweight PVC PT 37/52. The box also takes a built-in insect screen — insects outside in summer, warmth inside in winter.

SKO / SKO-P — an oval box as a facade feature

The SKO answers the same “shutters after the build” question differently: oval box is not hidden but shown off — on the wall it reads as a neat architectural detail. The SKO is made of extruded aluminium and holds its geometry on large windows, the SKO-P of sheet with a special PU/PA coating that resists abrasion and weather. It can be paired with the independent insect screen system Moskito, which works separately from the curtain: light and air in the room, insects behind the mesh.

SP / SP-E — concealed under render, passive house certified

For a new build or a house where the lintel is being rebuilt: the box disappears completely into the facade, and its front face serves as the base for the render — from outside only the curtain in its guides is visible. The construction touches neither the window nor the lintel, so the thermal envelope of the house stays intact. Boxes up to 165 mm are certified by the Passive House Institute (PHI) for energy-efficient buildings with windows of Uw ≤ 0.80 and glazing of Ug ≤ 0.70 W/m²K. We paint the inspection covers and guides to match the windows; an insect screen is optional.

SKT Opoterm — a built-on box with Neopor insulation

A built-on system for new builds and window replacement: a box in quality PVC with internal insulation Neopor (EPS) is fitted straight onto the frame via adaptor profiles — window and shutter are installed as a single unit. The coefficient measured by IFT Rosenheim for the SKT 230/170 box with an insect screen is Usb = 0.73 W/m²K. The front face takes any finish: render, insulation, brick — the box dissolves into the facade. Three versions (NOVA, RENO, MONOBLOCK), and one box can carry several curtains.

SKB Styroterm — a record Usb from 0.29

The warmest box in the range: from Usb 0.29 W/m²K in IFT Rosenheim testing — first place among comparable systems on the market. The 260×260 and 300×300 mm boxes hide within the insulation layer and are invisible from outside, and the adaptor profiles fit roughly 90 % of window systems. Inspection is from inside or outside through a clip-in aluminium profile that can be painted to RAL; for heavy curtains there are steel consoles with a thermal shield. The VENTI version is built for ventilated facades and clinker brick, with an MKT or MPH insect screen.

SDZ — the mechanism in an existing reveal

If the lintel already has space for a shutter — you are replacing old shutters, for instance — the SDZ system goes into the existing reveal quickly and without disturbing the finishes. Several build options to suit the reveal size and the fixing method, with a curtain of PA 39–55 profiles in a PU/PA finish or PVC PT 37/52. Any control you like: a cord, a motor with a switch or radio remote, or a smartphone.

Safety Plus (RC2) and Safety Premium (RC3) — when the shutter has to stop them

An ordinary shutter deters; a burglar-resistant one stops. Safety Plus is certified to class RC2: an extruded PE 41 curtain, reinforced PPW 66 guides and a patented ratchet lock in the LDG 41/W bottom bar that prevents the curtain being lifted from below. Safety Premium — the first roller shutter in Poland rated class RC3 to EN 1627:2021 (tested by the German IFT Rosenheim institute): a PE 55 curtain, specially reinforced guides from which the profiles can neither be bent out nor pulled free, and a latch mechanism at the bottom that blocks a closed curtain from being lifted. Insurers usually require this level for houses with valuables.

Controls and colours

From a simple cord to a smart home: a motor with a switch, a radio remote, smartphone control, and scenes such as “all shutters down” for the night or triggered by a sun sensor. The palette runs to more than 40 colours: eight shades of grey, ultra-white and ivory, timber textures in golden oak, walnut and mahogany, plus green, burgundy and black — so the shutters match your windows and facade exactly.

Which shutters suit a finished house and which a new build?

For a finished house the answer is surface-mounted SK/SKE/SKP and SKO, or built-in SDZ units (into an existing reveal). During a build or a window replacement it is better value to choose built-on SKT/SKB units on the frame, or concealed SP units under the render — the boxes disappear from view.

What do shutters give you besides burglar resistance?

Warmth and quiet: the SKB Styroterm box has a Usb from 0.29 W/(m²K), and the SP system is certified by the Passive House Institute. A closed curtain cuts heat loss through the window in winter and keeps the heat out in summer, plus it gives complete blackout in the bedroom.

How much protection do they really give against break-ins?

The dedicated ranges are certified to EN 1627: Safety Plus — class RC2, Safety Premium — RC3 (IFT Rosenheim) — with reinforced guides and an anti-lift block on the curtain.

Can an insect screen and automation be added?

Yes: the screen is built straight into the box (SK/SKT/SKB), and control can be manual, by motor with a switch, by radio remote, or through a smart home with sensors.
