Regulatory Information

All of our Secondary Glazing is Glazed in Accordance with Building Regulations:


BUILDING REGULATIONS N1 - Glazing safety in relation to impact

  • Approved Document N, Part N1, deals with Protection against Impact, defining areas of Critical (High Risk) Glazing & the Type of Glass to be used in those areas.

  • Glazing with which people are likely to come into (physical) contact whilst moving in or about the building shall;
    1. if broken on impact, break in a way which is unlikely to cause injury; or
    2. resist impact without breaking; or
    3. be shielded or protected from impact

  • Areas considered to be High Risk are;
    1. Windows where the bottom of the glass is within 800mm of floor level
    2. All glass within Doors from floor level up to a height of 1500mm
    3. All glass within Door Side Panels & Windows adjoining Doors from floor level up to a height of 1500mm & to a width of 300mm


  • Safe Breakage is defined in BS6206: 1981 'Specification for impact performance requirements for flat safety glass and safety plastics for use in buildings: paragraph 5.3.

  • In practice, Compliance is achieved by using Toughened or Laminated Safety Glass as specified in BS6206 in all Critical (High Risk) Areas

NB1    Although not specifically covered in Document N, locations such as windows next to baths or showers &           windows on stairs or landings should also be considered as Critical Areas if there is any risk of impact.

NB2    Due to the manufacturing process Safety Glass may appear to be of a slightly different 'tint' to normal glass.           Good Industry Practice is to install Safety Glass in all the panes of a Door or Window which Require any           Safety Glass. See Diagram 1 above, Panes 1, 3, 9 & 10 should also be glazed with Safety Glass in order to           achieve consistent light transmission.

Regulations for the Following Section are Different for Commercial Properties & Residential Properties

In Practice We Comply with the Following, More Stringent Regulation, which is for Residential Dwellings


All of our Secondary Glazing takes Account of Fire Safety Requirements:

BUILDING REGULATIONS B1 - Fire safety

  • For a typical Domestic Dwelling (storeys not more than 4.5 Metres above ground level) Approved Document B Requires that all Habitable Rooms (living rooms & bedrooms but not bathrooms or kitchens) on and above the First Floor must be provided with Emergency Egress (escape).

  • In addition, rooms at Ground Floor level whose' only Fire Escape is via another room are also required to be provided with suitable Escape Windows.

  • This means an External Door (above ground floor) or Window that Complies with the Specification contained at 2.11 of the Document: Any window provided for emergency egress purposes and any external door provided for escape should comply with the following condition.

  • The window should have an unobstructed openable area that is at least 0.33 Metres Square and at least 450mm high and 450mm wide. The bottom of the openable area should be not more than 1100mm above the floor.

  • In practise this is achieved by fitting an Egress Brand Fire Escape Hinge to a Designated Casement Opening in each Habitable Room on & above the First Floor.

NB     The above wording applies to the Primary Windows - Granada Designs Secondary Glazing Installations to          Ensure That Emergency Egress & suitable Escape Windows are Not Obstructed.

NB     Due to the original construction of some properties (particularly post war bay fronted houses) it is not always          possible to comply with the 2.11 specification, which was introduced in 2000. Latest News from the FENSA          website (02/10/02) states:

'The size of fire-escape provision in window refurbishment

In answer to recent questions concerning the above topic, senior representatives of FENSA, GGF and BBA, have agreed on their understanding of the requirements.

Their understanding is as follows:

Where a window that has been used as a means of escape is replaced with the same proportional fenestration as previously existed (i.e. transom and mullion and sash layout is the same) and modern materials are used, it is possible that the casement openers may create a slightly smaller aperture due to the use of larger sections. Where these windows are replacing existing frames, it is the opinion of the above, that a window of this design will still be acceptable to FENSA as a form of fire-escape, provided it is fitted with modern, 'fire-escape' type hinge which allows for full opening of the window to 90.

This understanding of the requirements applies only to refurbishment work.

The three organizations listed above will be discussing this view with the appropriate authorities requesting that they accept this 'understanding' of the Regulations.

Regulations for the Following Section are Different for Commercial Properties & Residential Properties

In Practice We Comply with the Following, More Stringent Regulation, which is for Residential Dwellings



All of our Secondary Glazing takes Account of Ventilation requirements:

BUILDING REGULATIONS F1 - Ventilation

  • Approved Document F1 deals with the Requirements for the Means (type) and Volume (amount) of Ventilation.

  • In practice, replacing 'like for like' in terms of the amount & size of opening Casements, Top-lights & Sashes will usually Comply.

  • If Replacements are not 'like for like' and the amount &/or sizes of openings are being reduced then it will be necessary to take measurements and make calculations to ensure Compliance with the Table below.





NB     Part F1 - 1995 recommends controllable trickle ventilation for all new buildings and refurbishments requiring          planning permission in order to combat condensation.


The recommendations are:

Domestic Building: Habitable Room - 8000mm2; Other Rooms - 4000mm2.

Non Domestic Building
(without mechanical ventilation): Occupiable Rooms and Rest Rooms - 4000mm2/10M2; Common Spaces - No Requirement; Other Rooms - refer to regulations but secondary glazing not normally supplied.


NB     Ventilators will reduce the effectiveness of Noise Insulation so if the level of Sound Reduction is critical wall          mounted Acoustic Ventilators may have to be considered.



GAS SAFETY (INSTALLATION AND USE) REGULATIONS - 1998

NB     The Installation of Secondary Double Glazing Must Not Interfere with the Permanent Ventilation provided via          the Primary Windows for the Ventilation of Gas Appliances.

Refer to Statutory Instrument 1998 No. 2451 - the Gas Safety (Installation and Use) Regulations 1998

BUILDING REGULATIONS L1 - Conservation of fuel & power in dwellings

  • It is Approved Document L1, effective from 1st April 2002, that has introduced the new Requirement that all Replacement Window & Door Installations must have Building Regulations Approval from the local Council.
  • The main thrust of L1, however, is Compliance with strict new Legal Requirements for the conservation of fuel & power in dwellings.
  • This is achieved by limiting emissions (escape of heat) through windows & doors by requiring that they meet laid down levels of insulation (thermal transmittance). Thermal transmittance is a measure of how much heat will pass through one square metre of a structure (door or window) when the air temperatures on either side differ by one degree. This measurement is known as the U-value. The lower the U-value the better the level of insulation, and vice versa.
  • Replacement Windows & Doors must have a U-value of 2.0 or less.


BUILDING REGULATIONS L1A, L1B, L2A & L2B      15/03/2006


Extend The Regulations to Cover New and Existing Dwellings and Buildings Other Than Dwellings

Material Change of Use
NB This Section means that the Regulations for New-Build Apply to the following situations:
Conversion of Residential to Commercial
Conversion of Commercial to Residential
Conversion of a House to Flats
Conversion of Flats to a House
