Thermal insulation, Alux VISS

The main feature of Alux VISS skylights is that they offer high insulation, significantly reducing the cost of energy consumption for the heating, cooling, and lighting of premises.

The insulating values of Alux domes are tested according to EN 1873 – Documents.

ALUX domes come in various material combinations: solid PC, acrylic, HEATSTOP acrylic, MW PC

HEATSTOP

Alux Heatstop skylights illuminate rooms with natural daylight, which signicantly reduces the cost of energy. Alux Heatstop skylights are made of Aglas IRR GOLD cast acrylic sheets in OPAL colour, and are a product of Akripol. Their special feature is reducing the overheating of internal spaces and preventing the penetration of heat into the room, while still allowing natural sunlight to enter. This characteristic of skylights made with this particular type of panel helps reduce energy/consumption for cooling and lighting spaces.

Advantages of Alux HEATSTOP skylights:

• Bright and uniformly diffuse in the premises
• Reduced heating and lower indoor temperatures
• Reduction of energy/ costs, especially for space cooling
• High insulation and excellent UV protection
• Possibility of designing various skylight shapes
• The effect of solar power (IR) reflection is stable, as it is built deep into the cast acrylic
• Smooth and glossy surface
• Golden glare IRR GOLD skydomes with excellent transparency

Materials

ALUX domes are made of various tyopes of materials. Certain characteristics of the materials are tested according to standard EN 1873 – Documents.

Acrylic – standard, heatstop

Skydomes made of cast acrylic sheets (cast PMMA opal and transparent colours) – premium UV stability. Skydomes made IRR (heatstop) acrylic sheets – reduction of solar gains or g-values.

They are mostly made of AKRIPOL Aglas cast acrylic sheets of various colours and thicknesses. The standard colours are OPAL and TRANSPARENT, but the AGLAS sheets are also available in other colours, even completely enclosed (non-transparent). The process of manufacturing gives the cast acrylic certain properties that are superior to similar materials (e.g. extruded XT PMMA acrylic sheets). Acrylic also provides an alternative to other materials, e.g. glass.

Stability and durability:

• The stability of the cast acrylic (Aglas) skylight is characterised by its durability and resistance to environmental impacts (UV, temperature influences). These properties are much better, compared to the XT PMMA (in the case of cast acrylic sheets, all components are built across the entire thickness of the sheets, but only on the surface with XT).
• It retains its colour and firmness, even after prolonged periods of exposure to bad weather conditions.

Compact polycarbonate PC

Solid polycarbonate (PC solid) skydomes – hail resistance. Hail is a common cause of damage to buildings and their construction materials. As a result, enormous costs may arise for the repair and replacement of damaged elements.

We use solid polycarbonate (solid PC), and implement it in our lighting systems in order to achive better resistance criteria. The ALUX domes made of cast acrylic sheets and solid polycarbonate are tested according to FM Approvals No. 4473.

Results:

• PMMA 4 mm: Class 1 or equivalent to classifiction HW3

–  Ice-ball diameter 32 mm

– Grain speed (incidence speed): 28m/s

– Nominal incidence energy 10.4 J

• PC solid 3 mm: Class 4 or equivalent to classification HW6-  Ice-ball or grain diameter 63.5 mm- Grain speed (incidence speed): 35.7 m/s – Nominal incidence energy 71.9 J

Segmented PPC polycarbonate sheets

Skydomes from segmented polycarbonate sheets for the improvement of insulation values.

Transparent polycarbonate sheets are used in the high-insulation domes VISS, VIS10, and VIS16. The polycarbonate sheetsused in VISS domes are thrmoformed in the form of skin arch layers, so they further help improve the insulatingvalues.

Shapes and dimensions

Skydomes are produced in various shapes and dimensions.

Round

Round domes are produced from all types of materials and in any type (VISS, …). More in the table below.

Pyramid/Prism

Pyramid and prism shapes can be found in the table below.

Square or rectangular

These are standard forms of Alux skydomes. They are manufactured from all types of materials and in any type (VISS). In addition to the standard dimensions in the table, ALUX skydomes can also be produced in other dimensions or adapted to the actual state in each project.

Opening Options

In addition to lighting, skydomes with kit materials (adjustable valves, opening frames, protective nets, …) also provide opening capabilities. The opening may be intended for the exit to the roof, natural ventilation, or natural smoke and heat exhaust. In terms of these basic opening functions, ALUX systems can be implemented in several variants of different mechanisms.

 2.Segmented domes

Variants, types, materials

Segments can be produced in 1-layer, 2-layer, 3-layer, and also 4-layer variants.

Dimensions

Formats

Round domes usually have larger dimensions:

• from approx. FI 250 cm to FI 1200 cm

LIGHT BANDS

Types of light bands

1. Segmented acrylic light bands

They are made of cast acrylic sheets or a full polycarbonate of standard colour shades. They are arch-shaped, thermoformed, and self-supporting. The ALUX skylight is modular – it consists of any number of thermoformed light segments/elements that together form a longer light band. The two end elements are closed.

ALUX bands are installed on various types of kerbs (polyester, metal, wood, concrete). The location of the roof mounting is optional (on a flat roof, in the ridge, over the ridge, along the ridge). The light bands can be implemented in 8 fixed widths, while the length is adjusted to the requirements of the project.

Ways of use

• Natural lighting of industrial buildings (production, warehouses, shopping centres), for extracting smoke and heat in the case of ventilation – NSHEV systems

• The position of the mounting on the roof is customised (over the ridge, in the ridge, parallel to the ridge, flat roof)

Dimensions

Formats

Production is possible in the following formats:

• 1-layer,
• 2-layer,
• 3-layer

Opening Options

In addition to lighting, segmented light bands with kit materials (upstands – kerbs, opening frames, protective nets, …) also provide opening capabilities. The opening may be intended for natural ventilation or natural smoke and heat exhaust. In terms of these basic opening functions, ALUX systems can be implemented in several variants of different mechanisms. More detailed information is provided here:

• NSHEV Systems
• Ventilation

2. Triangular light bands

Dimensions

Formats

The width of the bands is from 100 cm to 600 cm and the length is unlimited.

Variants, TYPES, materials

The ALUX triangular light bands are represented by a self-supporting aluminium structure and a filler from multiwall polycarbonate sheets. The colour of the polycarbonate sheets is either opal or transparent, and the thickness of the sheets depends on the required thermal insulation. For better insulating values, a combination of multiple panel thicknesses is available. The aluminium construction is usually in NATUR colour (in RAL by arrangement). If necessary, ALU profiles with thermal brake are available.

The bands correspond to the requirements of EN 14963:2006.
