The choice of correct glazing must take into consideration thermal insulation (winter and summer), acoustic insulation and safety features.
The performance and efficiency of glass in winter is represented by its Ug value: the lower the value the better insulator the glass is and the more money you save on heating bills. By combining more interspaces, using low-E glass, and including noble gases such as argon and krypton, glass thermal insulation characteristics can reach Ug values as low as 0.5: ten times better insulating performance than a single pane of 4 mm-thick glass!
Summer performance efficiency is given by glass’s ability to insulate from solar radiation in the summer months and is expressed by its solar factor SF. The lower the value, the more efficient the glass is at regulating the sun’s energy.
Acoustic insulation is defined with the reduction value of the external noise Rw expressed in decibels dB. A higher Rw value expresses a higher acoustic insulation capacity.
Italian Ministerial Decree of 5/12/97 establishes the limits to be met based on the intended use.

Frequently asked questions
-
Yes, provided it is chosen and sized according to its intended use. Safety glass with specific characteristics is used for these applications. The composition of the panes, dimensions, fixing systems and behaviour in the event of breakage all matter. A railing, for example, requires a different assessment from an interior door: safety comes from the design of the entire system.
-
Tempered glass undergoes a heat treatment that increases its mechanical strength and resistance to temperature changes; when it breaks, it shatters into small pieces. Laminated glass consists of multiple panes bonded with an interlayer that holds the fragments together if broken. The two processes can also be combined: the choice depends on the function and the level of safety required.
-
The risk of overheating depends on sun exposure, glazed surface area and the shading measures in place. Careful design combines appropriate glass with shading devices, such as brise-soleil or external blinds, to manage light and solar gains. It is therefore possible to create large, bright openings while ensuring summer comfort from the early design stages.
