1. Purpose of Attic Completion Work

Attic completion work is necessary when the existing space under the roof (attic) shall be used for housing or storing purposes.

1 attic floor beams, 2 trussed purlin, 3 roof rafter, 4 space under the roof, 5 inferior purlin

The constructional details to be taken into account for attics to be used for housing purposes differ from those to be considered for attics intended for storing use.

The use of attics for housing purposes, in any case, necessitates natural lighting and adequate lighting as well as adequate ventilation. This can be achieved by building-in suitable roof superstructures.

For attics intended for storing use, the insertion of prefabricated lying roof windows in the roofing will do. Roof superstructures for adequate ventilation and natural lighting can already be provided for when a new roof structure is being built.

The present booklet deals with completion of attics to be used for housing purposes only.
