Window Efficiency

A windows efficiency is actually down to all the parts that go to make the whole window. The window frame is actually a heat conductor and this is a factor also that will contribute. London Glazing tradesmen are experienced in all glass. This is applicable also for the windows U-factor. This U-factor is the rate at which a window will allow heat to flow through it. Referring to windows, skylights, and glass doors, the U-factor can just be applied to refer to just the glass or glazing on its own. The less the U-factor, and the effective the window, door, or skylight. the most important consideration is how the window actually works, because some types have a lower rate at which air can leak air than others, this improves your home’s energy efficiency. London Glaziers fit all types.

Hopper.
Hinges at the bottom and opening in. Just as with both awning and casement windows, these usually have low air leak rates as the sash shuts by pressing against the frame.

Single and Double-Hung.
Each of the sashes moves vertically in a double-hung window. The bottom sash is the only one that slides up in a single-hung window. These sliding windows generally have high air leak rates than projecting or hinged windows.

Single and Double-Sliding.
Each sash moves horizontally in a double-sliding window. There is only one sash that slides in a single-sliding window. As with single and double-hung windows, they usually have high air leak rates than projecting or hinged windows.

Awning.
Uses hinges at the top and opening out. Because the sash closes by pushing against the frame, they usually have low air leaking rates. Lower than sliding windows.

Casement.
Hinged on the sides. Look similar to an awning window, they generally have lower air leakage rates than a sliding window as the sash shuts by pushing against the frame.

Fixed.
Fixed panes that will not open. Once installed properly these windows are airtight, however, they are not suited in areas where window ventilation is required.

Thin Glass.
This type of glass has various uses, typically specialised and in lesser volumes and in the technical world. Thin glass is used for in microscope slides, which are normally 1mm thick, and for the similar cover glasses which are only a fraction of a 1mm in thickness. Float glass manufacturing can make very thin glass down to .4mm. Thin glass is used to perform specific functions in a wide array of equipment and appliances, various kinds of mirrors such as electrochromic mirrors and cosmetic mirrors, touchscreens and filters, glass masters and data storage glass discs, displays, and telecom equipment. London Glazing use different glass.

Appliances.
Flat glass is mainly used for home appliances, office equipment, and similar applications. The doors on yor oven are constructed of tempered glass and can stand very high temperatures. The tops of stoves and control panels are made of drilled, silk-screen printed and tempered glass in order to give high thermal and mechanical safety and to look good also. Fridges are equipped with silk-screened, tempered, edged and clipped glass for their shelving, this is so they are shock resistant and cab stand shocks and spills. Washing machines and dishwashers also use tempered glass in their drums and panels. Non-reflective glass is used in order to stop the glare that reflects from televisions, computer screens, glass cases and other screens. Photocopiers, scanners, and fax machines all use highly transparent glass for document images. London Glaziers recommend glass for homes.

Urban Furniture.
Glass is more prevalent in the urban envirnment than you might know, bus and tram stop shelters, advertising stands, kiosks, street lighting, traffic lights, and covered walkways all have large glass parts. Glass is really very easy for cleaning and highly very weather resistant. The best feature is that if it is damaged it can be fixed or replaced and is able to be made to resist vandals.

The glass we use is a mixture of sand and other minerals that are melted together at a really high temperature to produce a material that is perfect for a massive range of uses from packaging and construction to fibre optic technology. London Glazing can advise on glazing for your home.
A form of the glass occurs naturally within the mouth of a volcano as it erupts there is a formation of something called Obsidian which is glass like but very tough yet brittle and has very sharp edges. Obsidian has in the distant past been used for cutting tools and even been experimented with as a medical tool. Glass is actually more of a liquid as it stands, yet feels solid, but will at high temperatures become softer and look like a liquid. Of course this is why glass can be poured and manipulated, molded and blown. Today man has conquered glass productio and can make many different types of glass. London Glaziers understand the process for making glass.

The Making Of Glass.
The glass we know is manufactured initially with the melting of different minerals at really high temperatures. The principle element in this process is something called Silica, (which is one of the most commonly found sands on earth) which combines with limestone and something called soda ash and they are melted at around 1700°C. During this process the manufacturer can add various different materials to change colour or the glass’s properties. Glass can be covered with a coating, treated with heat, decorated or even engraved for different uses. When the glass is in a molten state it can be formed into things like windows, screens for cars or packaging, in fact there are lots of uses for glass. It will depend on it’s ultimate use as to the rate that it is cooled and also it’s composition.
