Window Energy Ratings

As part of the Governments overall initiative to reduce the levels of carbon dioxide emissions, they have put controls in place to reduce the energy lost from domestic dwellings

Window heat loss can account for up to 30% of the total heat loss from your home. Therefore replacement windows are now energy rated which will help to reduce harmful CO2 emissions and help cut the cost of heating bills. Ultimate window profiles along with the glass sealed unit specification are fed into a computerised simulation test to measure

Based on the results, windows are then rated from A-G with A-Rating being the most thermally efficient

Means of Escape

When replacing any window, the opening should be sized to provide at least the same potential for escape as the window it replaces. If the original window that is being replaced was larger than necessary for the purpose of escape, then the new window opening could be reduced to the minimum as specified in the criteria below

The means of escape should be considered for any new window installed to an extension or existing dwelling. If an escape window is required, then criteria set out below should be followed. It is also generally good practice to replace any window on the first floor that is not used as an escape window with an escape window

See below for the general criteria for egress windows:

  • Width and Height - Either of these are not to be any less than 450mm
  • Clear Openable Area - No less than 0.33m²
  • Cill height - The bottom of the openable area should be no more than 1100mm above the floor area

Only one window per room is required


Windows and doors provide ventilation to rooms within a dwelling and rules apply to how much ventilation. The type and extent of ventilation will be dependent on the use and size of the room. For example, rooms where steam will be produced (kitchens, bathrooms, utility rooms etc) should be provided with higher levels of ventilation (normally mechanical fans and windows) than other rooms where suitably sized window openings and background ("trickle") ventilators may suffice

Safety glazing

Safety glazing should be provided to any glass in a critical area. Below is a list giving general view as to when safety glazing is required:

  • Unobstructed openable area: At least 0.33 square metres and at least 450mm high and 450mm wide
  • Within any glazed door up to 1500mm from floor level

Unless otherwise stated, all glazing provided by Heronhurst is Safety Glazing (Toughened) as standard regardless of its location, for your peace of mind
