Fensa Notes 3 Double Glazing, UPVC, aluminium, timber replacement windows

FENSA Limited is the Fenestration Self-Assessment Scheme for companies that install windows and doors in dwellings.

Special Note: These are the interpretations being used by "FENSA registered companies". This is important because some of the local authorities may interpret some of the building regulations slightly differently. If you are not using a FENSA member and are going to apply to the local authority for permission rather than use a FENSA company you would be well advised to seek clarification before an installation commences.

Also worth reading are the FENSA Technical FAQ's at http://www.fensa.org.uk/faqtech.phtml

Inner Rooms - Definition

Approved Document B defines an inner room as "a room whose only escape is through another room (the access room)". Therefore any room that is not directly linked to a hall, or has its own external door, will require fire egress facilities to be maintained. Even if the access room has a doorway or similar facility opening to the outside. The only room types exempted are kitchens, laundry/utility rooms, bathrooms, and toilet or shower rooms.
