Glazing options

Standard glazing

Energy glass reduces heat loss from a property which is key to saving on energy costs. The glass is coated with a thin, invisible metal film that allows solar heat penetration but limits heat loss from the building when the outside temperature is lower than that of the inside. Energy glass is a standard component on all Broxwood windows and doors.

Glazing options

The additional glazing options listed below area available on most of our windows and doors. We’re happy to guide you on the best use of these options and how to combine the options to achieve multiple benefits.

Solar control glass is employed to reduce the effects of solar heating in south facing rooms. Solar control glass reduces transmission of light and heat into the room. To achieve this effect the glass is tinted. Various tints are available. The darker the tint the greater the reduction in transmission of light and heat.

Fire safety glass is sometimes a requirement in public buildings but can also be specified for domestic dwellings. The integrity of fire resistant glass is measured in how long it will hold back flames and hot gases. Regulations demand that the minimum ‘integrity’ time is 30 minutes. A second measurement is how well the insulation of the glass holds back the heat of the fire so that the temperature on the opposite side of the glass remains below specified levels. The minimum ‘insulation’ time is also 30 minutes.
Note: Fire rated glass must be installed into a frame that works in combination with the glass to ensure the whole installation performs to the required standard.

Noise reduction glass is most commonly used in conjunction with traffic noise. Typical two-layer glass insulate 25 Rw + Ctr and the human ear will perceive approximately 8 dB improvement as a halving of the sound. Broxwood offer products with soundproofing, 30, 35, 37 and 39 decibels.

Safety glass is designed to protect against injury and forced entry. There are two types of safety glass: laminated glass, and tempered (toughened) glass.

Laminated glass is two sheets of glass bonded together in combination with a flexible plastic film. The glass will crack when it is overloaded, but splinters of glass remain held safely by the plastic film. This prevents penetration and reduces the risk of cuts. Laminated glass also protects against UV radiation, and can halve the fading of interior materials.

Tempered glass can withstand 3.5 times greater loads than ordinary glass. When the tempered glass break it shatters into thousands of pieces which reduces the risk of injury

Self cleaning glass is useful for hard to reach windows or if window cleaning just isn’t your thing. A coating on the glass loosens the dirt leaving it for the rain to wash away. The surface coating causes the water to spread and run evenly over the glass surface so that the dirt is removed. All you need is a little rain or gentle use of a garden hose.
Please note: Self cleaning glass looks slightly blue from the outside. Self cleaning glass reacts adversely with silicone or oils containing silicone. The coating can be damaged by careless handling.

Obscure glass is offered in various patterns and degrees of obscuring. Level 1 pattern is least obscuring, Level 5 is most obscuring.

Coloured Glass is available in a variety of forms. It can be a genuinely coloured glass, a clear glass with coloured foil on one side, coloured foil laminated between two or more sheets of clear glass, enamelled glass and glass coated with a guarantee against cracking and flaking.
