Glass FAQ

Q: How can you tell if glass is toughened?

A: Toughened glass will usually have a printed label near the edge of the glass with details of the glass standard as relevant to the Country's specific glass standards. This is usually ceramic ink applied to the glass via a silk screen prior to furnacing. This printed label then fuses and becomes part of the glass during the toughening / heating process.

Q: Why does the toughened glass will incur self-explosion?

A: 1, One of the most common reasons is that the NIS caused spontaneous breakage.2, Moreover, if the toughened glass is not installed correctly, or if it's subject to physical shocks or vibrations, it may also shatter and explode.3, In some cases, the toughened glass may also explode as a result of thermal stress or human impact.

Q: How to choose the right glass for my windows and doors?

A: There are 3 main areas to consider when thinking about windows and glazing for your project: natural light, solar heat gain and thermal conductivity. By choosing the right performance glass, you can enjoy your views and natural light while controlling UV and glare.

Q: How to maintain glass after installation?

A: 1, It should be cleaned with a non-abrasive cleaner or a solution of water and ammonia. 2, It is important to clean the surface regularly and avoid using harsh chemicals or abrasive materials that can scratch the toughened glass. 3, A simple mixture of water and soap can be used.

Q: What Thick do you have for single glass?

A: 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm and 15 mm

Q: What effect does gas filling a double-glazed unit have on its performance?

A: Filling with Argon gas instead of air will improve the insulating capacity of the double glazed unit. This is reflected by a lower U value than would result from the use of air. The magnitude of the benefit varies with the size of the gap between the glasses in the IGU. The use of Argon in a 12mm gap will result in an improvement of approximately 6%. ROPO only supply Argon gas as a standard across our complete double glazed range.

Q: Why is the window U value different to that of the glass?

A: The U value for a window is the combination of the U value of the glass and the U value of the frame. The frame is made of a different material to the glass so will have a different U value to the glass. The overall U values of window system using aluminium, timber or PVC frames for example will all be different even if the same glass is used in each case.

Q: Is there a different between toughened glass and tempered glass?

A: There is no difference between two. toughened glass is also called tempered glass as it goes through the heat or chemical tempering process
