Hello,

our single-family house is currently being built. The rafter fields of the roof slopes and the ceiling surfaces on the upper floor are insulated with mineral wool mats. A plastic film is planned as a vapor barrier under the mineral wool mats. The cladding is done with drywall panels.

Now I have a question: The attic is unheated (cold roof) and is ventilated through the ridge. We want to use the attic as a storage room.

Which floor covering is best suited for the attic? What should one pay attention to?
Can the floor covering be laid directly on the collar beams?

Thank you very much

In most unfinished attics, tongue and groove boards are used. Depending on the rafter spacing, the thickness of the tongue and groove boards should be considered. I have a rafter spacing of 90 cm and chose a thickness of about 22-23 mm. Very good for normal storage use. Of course, if you want to store 1 ton of gold bars per square meter, you should consult a structural engineer.

Hello, just a thought: Depending on the structural system, it may be necessary to design the collar beam layer as a diaphragm. There should then be a note about this in your structural analysis. If this is the case, some special features must be observed during execution. Regards w - bpb

Hello,

what does it mean: Depending on the structural system, it may be necessary to design the collar beam layer as a diaphragm?
What should I imagine by that?

Regards
