| Warning! You
should always check with your local authority before commencing any work as to the current regulations and advices of the day. Joe Public cannot be held responsible (see disclaimer). The Building Regulations - Replacement windows, certain door and roof lights to dwellings. Even more on Document L and building regulations! - A SUMMARY - THE FACTS FENSA self-certification scheme There are two ways that you can ensure compliance with relevant regulations, firstly you may employ a contractor or installer who is registered under the FENSA self-certification scheme. This contractor will be approved to carry out the work in accordance with relevant regulations without inspection by the council and will inform FENSA when installation has been completed. Random inspections of completed work are carried out. In addition to Building Regulation consent you must ascertain whether or not planning permission or conservation area consent is required. The Development Control section of the council can advise you on this. If you are not using a FENSA registered contractor or if you're doing the work yourself then you will need to arrange building regulation approval yourself. In short this means you need to be able to confirm the following: The replacement will achieve a U-value of 2.0 W/m2k for PVC or timber frames, or 2.2 W/m2k for metal frames. Glazing within critical locations will be replaced with safety glass. Existing measures for background and natural ventilation will be retained. Existing measures for means of escape from relevant rooms will be retained. (If the window pattern is to be changed this may affect means of escape). Open flue appliances affected by the window/door replacement will be checked for adequacy of combustion air supply by a suitably qualified person. If necessary, a suitable means of support will be provided above the replacement window/door. Where the dwelling was required to be constructed to provide an easily accessible threshold at entrance doors this will be retained. Replacement Windows and Doors As from 1 April 2002, Building Regulations request that building owners installing replacement windows or doors must obtain Building Regulations consent and have the installation inspected to ensure compliance with relevant regulations. The relevant regulations are: L1 Conservation of fuel and power N1 Glazing protection against impact In addition, you must also ensure that replacement windows and doors are no less suitable than the existing windows and doors in relation to the following regulations: A1 Structure B1 Means of escape in fire F1 Means of ventilation J2 Combustion appliances and fuel storage systems K2 Protection from falling M2 Access and facilities for disabled people Repair work, such as replacement glazing or repair of rotten or damaged frame members is not subject to Building Regulation approval. Guidance on how to satisfy the requirements Requirement A1-structure. When installing new windows or doors an assessment should be undertaken by the contractor as to the suitability of the support of lintel above the replacement window or door. Requirement B1- means of escape in fire All windows to habitable rooms (but not kitchens, utility rooms, dressing rooms, bathrooms, wc's or shower rooms) at floors above ground level are required to be suitable for escape in fire. In addition, rooms at ground floor level whose only escape route is via another room must be provided with suitable escape windows. A suitable escape window is defined as 'a window whose unobstructed openable area is at least 0.33m2 and at least 450mm high and 450mm wide (a 450mm wide opening will need to be 735mm high). The bottom of the openable area should be no more than 1100mm above the floor. Any key required to open the window should be readily available. F1-means of ventilation See table 1 below for current requirements. If your original windows have trickle ventilators any replacement frames should also be provided with such. The area of opening windows should not be less than that which was originally provided. As and alternative approach to the ventilation provisions listed in table 1 below, the overall provisions for background ventilations for the dwelling should be equivalent to an average of 6000mm2 per room for the rooms listed, with a minimum provision of 4000mm2 in each room.

Table 1 Ventilation: current requirements for various rooms Room Rapid ventilation Background ventilation Habitable room 1/20th of the floor area of the room served 8000mm2 Kitchen and utility Opening window (No minimum size) 4000mm2 Bathroom/Shower rooms Opening window (No minimum size) 4000mm2 Sanitary accommodation 1/20th of the floor area of the room served 4000mm2 J2 Combustion appliances and fuel storage systems Certain fires and heating appliances relay on air infiltration for them to function correctly. They may require purpose made ventilators, or may have relied on air infiltration through existing ill-fitting windows and doors, If you have an open flued appliance in the house that does not have separate provision of combustion air, a check should be made by a suitably qualified person (CORGI, HETAS, NACE, NACS, etc) to ensure that adequate permanent combustion ventilation is provided. The boiler or fire manufacturers manufacturer's advice should be followed with regard to proximity of opening windows and doors. K2 - protection for falling Where a first floor window cill height is less than 800 mm above the floor level suitable guarding should be provided to prevent a person falling through an open window. This requirement may conflict with Regulation B1 and provision of escape windows. One way of achieving the requirement may be to provide a restricted opening device that can be easily overridden in the event of an emergency. L1- conservation of fuel and power All UPVC and wood replacement windows should attain a U value of 2.0W/m2K. One way of achieving this requirement is by providing a UPVC or timber double glazed window system incorporating a 16m air gap between panes and an approved low emissivity coating such as Pilkington K. This is not the only option, but if another system is used, substantiation may be required to prove that a U value of 2.0W/m2 is attained. M2 - access and facilities for disabled people Where the property was subject to the Disabled Regulations, any new principal entrance door should have a minimum 775mm clear opening with a low threshold. N1- glazing protection against impact Glazing should either: Break safely as defined in BS 6206:1981 Specification for impact performance requirements for flat safety glass and safety plastics for use in buildings, clause 5.3 Be inherently robust, i.e. annealed glass, glass blocks, polycarbonate or glass that gains strength through thickness. Be in small panes (a maximum area of 0.5m2 with a maximum width of 250mm is acceptable). Annealed glass should be not less than 6mm thick, except where it is in traditional leaded- or copper- lights in which 4mm glass is considered acceptable when fire resistance is not a factor. Be permanently protected by a suitable screen which has a minimum height of 800mm and which incorporates a gap no greater than 75mm.
