Design studioFor the correct choice of glass to be used, the developer must provide the following information: the area where the building is situated, building size, number of supports of the window, the window size, its location in the front or in the coverage and intended use.
Please remember to carry out an analysis of the possibility of thermal shock.
Risk of rupture by thermal shockA localized heating, with the temperature difference between two adjacent zones of the same glass (normally evaluated more than 30 °), it can cause breakage of glass. Where this risk exists (IG lag behind the facade, shadows from curtains, high energy absorption …) it is necessary to subject the glass to hardening or tempering.
MATT AND CURTAIN WALLS
A glass also partially located in front of an opaque wall must be treated to resist thermal shock. In the case of interior blinds, curtain-glass space must allow for sufficient air circulation.
The minimum distance from the glass is 40mm.
Stained glass placed in passagewaysTo avoid the risk of being invested because of the remarkable transparency of the glass, you need to become conspicuous with decals or decorations.
They should not be written in dark colors of tempered glass is not exposed to direct sunlight for risk of thermal breakage.
LayingThe installation must always be carried out using dowels and / or seals to prevent any contact between glass to glass, glass to metal, glass and cement.
To avoid damage to the waterproof seal of the IG or the deterioration of the interlayer of laminated glass, the water should not stagnate in the bottom of the groove of the window support.
On the bottom of the groove of the window, the window in which you will find accommodation must be correctly positioned the pieces of peripheral and lateral support.
The width of the blocks must be at least equal to the thickness of the glass itself.
Yard storageThe stained glass windows in expectation of laying, shall be kept on easels in places well ventilated, protected from weather and direct sunlight. Do not approximate heat sources that could create a localized heating to the glass. All products laminated should not be subjected to prolonged at a temperature higher than 60 ° C. The same applies to windows with low-emissivity or selective, and stained glass.
The material is transported in the pipeline for the installation must be lodged the minimum time required for the implementation, in a safe place and repaired.
- The glass must be protected from rain and moisture (against the risks of oxidation), the sun (against the risk of thermal shock), dust and contact with harmful materials (cement, lime, welding sparks, etc.).
- glass products (plates, insulation panels, etc..) must be supported by a strong plan, usually vertical, with a slight tilt and using suitable blocking material (cardboard, paper, cloth, etc..) to avoid direct contact with the wall and between a glass and the other.
Acceptability of the productEVALUATION OF OPTICS AND VISUAL IG
Torsellini Glass adopts the requirements of UNI – TR 11404 of February 2011 “Insulating glass units for use in construction – for visual and optical quality frames”, a document that reproduces in full the requirements of the specification Assovetro Associations Investments-November 4, 2009.Optical and visual quality for frames
The tempering treatment may cause slight deformation of the surface of the glass that create distortions in the reflected images, but which are widely accepted by law.
MaintenanceThe building owner shall ensure the proper and regular maintenance of the windows.
This includes window cleaning, testing and repairs of frames and joints, the verification and the eventual release of the drainage holes and ventilation, testing of metal parts assembly and anchor, and the search for any anomaly.
The frequency of maintenance depends on the external environment and the particular pressures they are under the windows.
The most common conditions is carried out at least one annual intervention.
To wash using clean water and non-calcareous or neutral detergent, non-abrasive or fluoride. Immediately after drying the entire surface of the glass. Make sure that the tools and cleaning rags are free of abrasive particles.
The frosted glass can be cleaned preferably with a microfiber cloth slightly dampened with water, taking care to pass in the same direction.
On untreated glass (and on the glass with coating available) stains of grease and oily substances must be removed by isopropyl alcohol or acetone, to avoid spreading the staining. The cleaning solvent must be immediately followed by normal washing and rinsing water.
