Aluminante makes glazed roofs on aluminum frames: retractable roofs that slide open on a motor, fixed glass roofs for terraces and verandas, and insulated roofs for winter gardens that are heated through the winter.
Glazing runs from 10 mm tempered glass to a 46 mm insulated unit, spans reach 26 meters, and the systems carry 180 to 220 kg/m2 of snow, with up to 400 kg/m2 on the ACURA Q27 glass roof. Drainage is built into the frame: gutters inside the beams, water down the posts.
Every roof is made to the project drawings and powder coated in any RAL color.
Aluminum Skylight and Glass Roof Systems
Aluminum skylight and glass roof systems
Aluminante makes aluminum skylight and glass roof systems, fixed and retractable. In the UK the same range is often called glazed roof systems or aluminium skylights. A skylight is a glazed opening in a roof. It brings daylight into a room that has windows on one side only, or none at all: a hall, a stairwell, a kitchen extension, a covered terrace.
A roof window sits in a pitched roof and opens like a window. A skylight, in the sense used here, is a glazed roof structure on its own aluminum frame, from a single pyramid over a stairwell to a 26 m span over a pool. The frame carries the glass, the drainage and, where the roof opens, the drive.
Four types of glass roof we make
The choice starts with one question: does the roof have to open, and does the room under it have to be heated.
| System | Opens | Glazing | Size | Load |
|---|---|---|---|---|
| SKYTECH | Yes, panels slide on a Becker drive | 36 mm double glazed unit | projection up to 8 000 mm per module, panel up to 1 250 mm | 180–220 kg/m² |
| PRADA | No, fixed | tempered or insulated glass 10 to 36 mm, or polycarbonate | modules up to 7 200 mm wide, projection up to 6 000 mm, pitch 4–8° | 180–220 kg/m² |
| PARETTI Thermo Pro Q43 | No, fixed | insulated unit 26 to 46 mm, thermally broken profile | pitch 5° to 45°, large unsupported spans | high load capacity |
| ACURA Q27 Paretti | No, fixed | glass 4 to 52 mm, 34 mm polyamide thermal break | module up to 7 000 × 4 000 mm | up to 400 kg/m² |
| PAVILION | Yes, vaulted sections slide | glass or polycarbonate | up to 26 × 60 m | up to 220 kg/m² |
Which one fits your project
Terrace that works all year
A retractable roof: closed in the rain, open on a warm evening. SKYTECH over a terrace, PAVILION over a pool or an atrium.
Heated room under glass
An insulated roof with a thermal break: PARETTI for a winter garden, ACURA Q27 Paretti on a pergola frame.
Cover without heating
A fixed glass roof: PRADA over a terrace, a veranda, an entrance or a carport.
Daylight into a dark room
A fixed glazed structure over a stairwell, a corridor or a kitchen extension, built to the opening size.
Glass, loads and drainage
Tempered glass of 10 to 12 mm is the light option for an unheated cover. An insulated unit from 20 to 46 mm belongs over a heated room: it cuts the summer heat, holds the winter warmth and makes rain on the roof much quieter.
Loads are calculated per project. The systems carry 180 to 220 kg/m² as standard, and the ACURA Q27 glass roof up to 400 kg/m².
Every system drains inside itself. Gutters run in the frame and the water leaves through the posts, so nothing drips over the edge onto the table or the entrance below.
Where these roofs are installed
Restaurant and hotel terraces that have to trade in winter, private winter gardens and sunrooms, swimming pools, atriums and lobbies, sports courts, house extensions and carports.
Frames are powder coated in any RAL color, so the roof matches the joinery and the facade rather than fighting them.

Aluminum skylights and glass roofs: frequently asked questions
What is the difference between a skylight and a roof window?
A roof window is a single unit fitted into a pitched roof. A skylight here is a glazed roof structure on its own aluminum frame, built to the size of the opening, from a small pyramid to a span of tens of meters.
Can a glass roof open?
Yes, two of our systems open. SKYTECH slides its glazed panels on a Becker drive, PAVILION slides vaulted sections over spans up to 26 by 60 m. PRADA, PARETTI and ACURA Q27 Paretti are fixed.
Will a glass roof overheat the room in summer?
Not if the glazing is specified for it. Selective and tinted units cut the solar gain, and screens or blinds run on the same frame. An opening roof solves it directly: the hot air leaves.
What about snow?
The systems are designed for 180 to 220 kg/m², and the ACURA Q27 glass roof for up to 400 kg/m². The spans and the glass are calculated for the snow load of your region.
Is the roof watertight?
Yes. The glass sits on seals and the frame has its own gutters and downpipes, inside and out. On the sliding systems the panels close onto gaskets.
Can you make a skylight to a non-standard shape?
Yes. The structures are made to the project drawings: flat, pitched, vaulted, pyramid, or set into an existing opening.
