Legal terms and declaration under art. 104 of the Consumer Code
1. CASALI has made of safety its first rule and places on the market only safe products under art. 104 of Consumer Code
2. All CASALI products meet the criteria and standards of quality and safety currently applied in the sector. In particular, for the production areas Doors, Solutions, Projects, all glasses are tempered.
All the glass used by CASALI in manufacturing its products are produced in a nickel-free process which ensure the absence of nickel-sulfur particles, leading cause of spontaneous breakage of the glass sheets made with other systems.
CASALI glasses are submitted to tempering, which is a thermal process that, in addition to harden the structure of the glass and make it more resistant, causes a thermal shock that, in case of defects, will make the glass explode in fragments inside the oven or within 24 hours from cooling down.
As an additional guarantee of quality and safety its products and accessories, the Manufacturer has subjected them to certification. This certification is based on compliance with the standards and rules UNI, particularly stringent, requiring the manufacturer high quality standards.
Products has been submitted to initial verification and periodical checks from an independent laboratory who made the analysis and certified the performances of the products.
Compliance with UNI norms ensure that the performance achieved is higher than the minimum legal standards, certifying the quality of CASALI products

9. Dimensional tolerances for flat and curved glass
Here below the dimensional tolerances for CASALI glasses.
For curved glass: Bending +/- 5mm, straightness +/- 3 mm per meter, warpage +/- 5 mm.
For flat glass: straightness +/- 2,5 mm per meter.
For flat and curved glass: Sizing, shaping, drilling +/- 2mm.
10. PRODUCTION METHOD AND CONSIDERATIONS :
From a chemical - physical viewpoint glass is an amorphous solid or a liquid with high viscosity, which is produced by rapidly cooling molten siliceous material.
Any imperfections in glass, such as the presence of tin spots, must be considered intrinsic to the production method and so cannot constitute grounds for a dispute.
“All of the materials used for the glazing have an intrinsic colour determined by the raw materials of which they are composed, a colour which becomes more obvious as the thickness of the sheet increases.” (Assovetro)
Tempered glass is obtained by hardening by means of thermal treatment (tempering).
Tempered glass is up to six times stronger than not tempered one. This is due to the fact that superficial defects are “closed” by compressive mechanical stresses, while internal part remains more free from defects that can cause cracks.
From an optical viewpoint the sheet of glass may have distortions caused by the tempering process compared with a piece of glass which is not tempered.
Any imperfections in glass, even minimal signs of tempering, must be considered intrinsic to the glass production method and so cannot constitute grounds for a dispute.
The thermal hardening process leads to have differently tensioned areas in the cross section of the glass.
This creates a bi-refractive effect , visible under polarized light (anisotropy-iridescence). When looking at soda lime silicate thermally toughened safety glass under polarized light, tensioned areas appear as colored zones, commonly named "leopard spots".
Polarized light is a part of normal daylight and its amount depends on the weather and the angle of the sun. The bi-refractive effect is most noticeable when observing with a strong angle or through polarized lenses.
Bent glass is glass which is subjected to gradual heating to high temperatures (between about 500°C and 750°C) until it becomes plastic enough to be able to adhere to a concave or convex mould in the bending furnace.
Usually curving of the glass is assisted by mechanical or pneumatic devices, which facilitate the process, bending the glass to higher viscosities such as not to affect the original characteristics of the glass sheet after contact with the mold.
Bent glass cannot be obtained without the glass itself being marked by the structure, even minimal, of the mould. Said process compromises the transparency and uniform thickness of the sheet. The bending process ends with instantaneous cooling, to obtain tempered bent glass.
Any imperfections in glass, even minimal signs of tempering and/or of the mould used, must be considered intrinsic to the bent glass production method and so cannot constitute grounds for a dispute.
The engraving process carried out by Casali on its glass is performed manually by the operator and, therefore, there may be slight variations in shape and finish, even for the same pattern, compared with the samples supplied by the Company.
These slight differences are characteristic of the process in which craftsmen work the product and add value, meaning that each door made by the Company is unique.
Small differences or a lack of homogeneity in engraving must be considered intrinsic to the working process and so cannot constitute grounds for a dispute.
Painting of the engraved glass by Casali is carried out manually using a suitable brush.
Slight differences in shade and finish are characteristics of this handcrafted work and mean that each door is unique, even different doors made with the same pattern.
Therefore, small differences or a lack of homogeneity in the shade and in the way the painting is carried out must be considered intrinsic to the working process and cannot constitute grounds for a dispute.
Casali coloured glass is the result of a cold lacquering process carried out manually, with the application of several coats of lacquer separated by drying periods which are affected by the temperature and humidity of the environment.
Said process may cause slight deviations in shade when making the same colours, therefore slight variations in finish compared with the samples supplied by the company must be considered characteristic of the colouring process performed by craftsmen and cannot constitute grounds for a dispute.
A thin layer of silver or aluminum is fixed to the glass (on the opposite side of the reflective one) for electrolysis and coated by a protective paint. Then we proceed with the lacquering of the glass.
Any imperfection of the silver surface with dimensions not exceeding 3 mm are intrinsic to the silvering process and therefore cannot be contested (example: small blooms, scratches or areas of non-deposition of silver).
EVALUATION OF ELIGIBLE DEFECTS:
Here are the guidelines for assessing the eligibility of any defects found on the glass for use in buildings.
"The examination of the glass must be performed from a distance of at least 1 meter, observing only from the inside outward, in an upright position and frontal (perpendicular) with respect to the glass surface.
The examination must take place under conditions of diffuse daylight (as, for example, overcast sky) without direct sun or artificial light. The glasses inside the rooms (internal glazing) must be examined with diffused lighting upright and frontal. "
"Any inclusions, bubbles, spots, stains ≤0,5mm dimensions are not considered defects.
The local concentration of inclusions, bubbles, dots, spots, loose point and surface residues, and so on, is permitted if it does not cause visual impairment and, in any case, not exceeding 3 mm. "(Assovetro)
Shadings, deposits of pigments, surface undulations, depend on the technique of lacquering and are still to be evaluated with the above criteria.
The materials and, in particular lacquering, are subject to a natural aging process which also depends on conditions of use.
For tempered glass, the localized flatness is measured parallel to the edge at a distance of 25mm from it, using a straight rigid ruler 300mm long. The maximum permissible value of undulation is 0.5 mm over a length of 300mm, while the overall undulation on the glass length cannot exceed 3mm every 1000mm of length.
11. MAINTENANCE OF CASALI PRODUCTS
For the maintenance of engraved/sandblasted products we suggest to use only the specific cleaning kit for engraved/sandblasted glass supplied with the product, following the instruction of the package leaflet. Painted parts must be only dusted with the specific microfiber cloth supplied, without using any cleaning product.
For the maintenance of lacquered products we suggest to use only the specific cleaning kit for lacquered glass supplied with the product, following the instruction of the package leaflet.
For the maintenance of transparent or etched glasses we suggest to use standard cleaning products for glass, not containing alcohol or solvents.
Be very careful to avoid any contact of engraved and sandblasted parts with silicone or similar products that can affect irreversibly the aspect and surface of glass.
During the installation of pocket door jambs, if not purchased from Casali, be sure not to install the brushes that can affect the sandblasting on the glass.
12. ACCESSORIES FINISHING
Accessories materials and finishing techniques can have different technologies.
A particular standard is used to define a color. The standard that is generally used is CIE in 1976. This is the color space L * + a * + b * (also known as CIELAB) which is currently one of the most popular color spaces for color measurement of an object And it is widely used in all fields. In this color space, L * indicates the brightness while a * and b * the coordinates of chromaticity.
Based on these definitions there are no contestable finishing up to 6 points of difference in the CIELAB parameter.
The ten-year warranty immediately upon the occurrence of one of the following:
