Sealed Unit Options
As a minimum, a sealed unit must be replaced with the same specifications as the old unit. A replacement might offer an opportunity to upgrade the design. This can range from better energy efficiency, safety glass, solar control glazing, low-maintenance or obscured glass to design features like leaded, stained or bevelled glass to Georgian or duplex grilles.
The manufacturing process of float glass involves "floating" molten glass onto a flat bed of molten metal. This process enables the glass to self level and gives it an equal thickness. Most other types of glass are an upgrade of normal float glass.
Obscured or patterned glass provides privacy while allowing maximum light through the glass. The glass is made by applying a texture to one side of the glass. There is a wide range of textures available, which provide different degrees of privacy.
Toughened Safety Glass
Toughened safety glass is essentially float glass, which during manufacturing, is heated up until it begins to soften and then cooled at a fast rate. This makes the glass stronger, but if it breaks causes the glass to shatter into smaller lighter fragments, making it less likely to cause injuries. Toughened safety glass is a requirement in high risk areas such as doors and low windows.
Laminated Safety Glass
Laminated safety glass is made up of two or more sheets of glass bonded together with a plastic interlayer. In the event of breakage, the glass fragments remain bonded to the plastic interlayer. The glass fragments are held together and the glass retains a residual strength. Therefore laminated glass can often be left in place while awaiting replacement.
Low-emissity (low-E) Glass
Low-E glass has a special coating applied to one side of the glass, which reflects long-wave heat back into a room, thereby retaining heat within a building. Low-E glass reduces heat loss, but promotes passive solar heating by letting heat from the sun pass through.

Solar Control Glass
Solar Control Glazing is designed to reduce solar heat gain by blocking up to 2/3 of heat from the sun light by reflecting it to the outside. It can be used in large areas of glazing where overheating is a problem, like conservatory roofs or south-facing patio doors.
A permanent, transparent coating on the outside surface of the glass harnesses the power of both sun and rain to efficiently breakdown and remove dirt and grime such as dried, dirty water marks, dust and insect residues. Low-maintenance glass requires less cleaning and is easier to clean, should it be necessary.Top
