Toughened Safety Glazing and Building Regulations

Toughened Safety Glazing is a very important factor in modern building regulations. You will need to take this into consideration when replacing your Timber Windows and Doors. You will also need to ensure you are complying with relevant regulations as Dwellings are required to be energy efficient.

Energy Efficiency

A method of achieving greater energy efficiency is to take steps to reduce the amount of heat that is lost through the glazing in both Timber windows and doors.

If you are to install windows and doors you should be aware that they need to comply with the requirements of the Building Regulations in relation to the amount of heat that can to pass through the glass and framework, which is measured as a U-Value.  This U-value should not be exceeded.

For information on the maximum U-Value allowed please refer to Approved Document L-1B, Table 1. We manufacture our Double-Glazed Timber Windows with a U-value of 1.5.

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:

  • Any glazed area within a window below 800mm from floor level
