LIGHTWEIGHT

Polycarbonate is a lightweight material that is used in the construction industry to reduce building costs while guaranteeing compliance with positive and negative wind load requirements.

TRANSLUCENT

A key feature of polycarbonate is its transparency. The use of natural lighting, achieved by installing translucent polycarbonate roofing and walls, creates a more comfortable ambience while also ensuring good thermal insulation. Polycarbonate can be suitably tinted to modulate light transmission, optimise shading and thus reduce overheating inside the building. Coloured pigments are used to achieve pleasant colour effects to satisfy the most demanding aesthetic and architectural requirements.

UV AND HAIL-RESISTANT

The exterior surface of the panel is coextruded with high-performance UVabsorbing polycarbonate to ensure excellent protection against ultra-violet rays, hail and accidental impacts even after prolonged exposure to sunlight.

VERSATILE

We supply an extensive range of products for use in the construction of translucent roofing and walls, skylights, fixed and openable insulated windows. Our continuous research has led to the development of a series of steel and aluminium accessories to complete the range. These are designed to make installation simple and safe and ensure compliance with the applicable fire and load strength ratings and safety of building requirements. Our products are all certified to the latest thermal insulation and energy saving standards.

SAFE

Polycarbonate has a particularly high impact strength. Our products are therefore highly resistant to accidental impacts and hail and meet the requirements of safety standards for translucent glazing in public and work environments.

AN ENVIRONMENTALLY FRIENDLY MATERIAL

The various phases of polycarbonate processing involve very low energy consumption and environmental impact. Polycarbonate is an energy-efficient solution and is totally recyclable at the end of its life.

CHEMICAL RESISTANCE

Polycarbonate has good resistance to most chemicals with which it is likely to come into contact during normal use. Specific tests are recommended for applications where the material is likely to come into contact with aggressive chemicals. It is essential to verify their compatibility prior to use. The table at the side provides a summary of reactions with some of the main products used.

LIGHT TRANSMISSION (τv)

Different pigments are used to obtain different light transmission values. The values indicated in the table are based on calculations performed at specialist laboratories.

SOLAR FACTOR (g)

Incoming solar radiation is reflected, partially absorbed, and transmitted to the inside. The solar factor indicated in the table is the ratio, expressed as a percentage, between the total energy transmitted to the inside and total solar radiation.

SHADING COEFFICIENT (SC)

The shading coefficient of a transparent sheet is the ratio between the sheet’s solar factor and the solar factor of a clear sheet of glass with a thickness of 3mm (SC=g/0.87).

THERMAL TRANSMITTANCE (U-VALUE)

The thermal transmittance U, in building physics, identifies the building element attitude to transmit heat if subject to a temperature difference. In particular, it is defined as the rate of heat loss through a unitary surface per degree centigrade difference in temperature between the two sides and depends on the material properties, on its structure and the linear thermal transmittance conditions.

ACOUSTIC INSULATION (Rw)

Sound insulation refers to the ability of the material to resist the transmission of impact sound. It varies according to the frequency and the physical properties, dimensions and installation constraints of the component.

NEW PRODUCT RANGE

The PoliCarb® IR, PoliComp® IR sheets and arcoPlus® IR panels let light in but not heat. They make up Dott. Gallina’s new product range for transparent coverings and windows with solar control. All products from the IR line offer innovative solutions for typical building applications where high levels of light are wanted while reducing the internal heating.

The potential result: reduced energy spending for cooling and for lighting as well as higher comfort. The multiwall sheets, and the modular arcoPlus® IR panels offer incredible design flexibility in applications such as skylights, windows, greenhouses, conservatories, and many others thanks to the wide range of available products.

INTERNAL TEMPERATURE REDUCTION COMPARISON

Testing proves that products with a protective infra-red filter can significantly reduce internal heating.

NATURAL PROTECTION

The heat coming from solar heating is for the most part absorbed by the external surface, treated with IR absorbers, that limits radiation to the inside of the building and the consequent heating up.

SOLAR CONTROL TO DEFEAT THE HEAT

The control of the temperature and the management of heat are essential elements in maintaining a desired level of comfort within buildings. They are also critical elements for cost control and to maximize energy savings. The products of the IR line absorb the part of the light relative to the infra-red rays (from 780 to 1400nm), effectively blocking the solar heat, while letting the solar light through. The result is a reduction of the internal transmission of heat and a reduction of the cost for cooling the area. In fact all the products from the IR line can contribute to reducing the temperature increase up to 25 with respect to other window products.

THE LASTING WARRANTY

All the products in the IR have a written guarantee of 10 year against the reduction of the properties of light transmission, yellowing and breakage caused by hail.

ENERGY SAVING

The multi-wall structure of PoliCarb® and arcoPlus® offers a real advantage in terms of thermal insulation. Calculated according to the guidelines of DIN 4701, there is a significant difference in fuel consumption between an industrial building with glass windows and the same building with multiwall polycarbonate glazing.

CLEANING

To clean sheets and panels we recommend the use of water and neutral detergent only. Do not use abrasive products.

THERMAL EXPANSION

Polycarbonate is subject to thermal expansion of 0.065 mm/m°C. When installing polycarbonate sheets and panels always allow enough room for expansion. If anchoring systems are used these must consist of the specific brackets and connectors provided for each product.
