Question

Options for lining a shed ceiling.
Woodsolutions Answer +

We suggest a plywood product. If you search the net with the words 'plywood ceiling' you will find products such as Ecoply that will do the job. Plywoods with grooves to simulate tongue and groove boards are available, as well as more economical options if appearance is not important.

Question

Client has installed a new spotted gum T & G floor on new joists with interfloor insulation . The house is a Federation house with a new concrete slab apron around the perimeter and an ag line. They had it acclimatising for 2 weeks in the interior under a fully enclosed house. They say the expansion joints are squeezed and the floor is bowed. The floor has a water based polyurethane finish ,which has had temp covering over it for protection. The house has not been occupied yet. What are your recommendations to remedy this?
Woodsolutions Answer +

Clearly the flooring has taken up moisture from somewhere, causing it to swell. The first step is to find the source of moisture. We suggest you check the sub-floor ventilation to make sure it meets NCC requirements. The NCC calls for ventilation openings ranging from 2000 to 6000 mm2/m of external wall, depending on the climatic zone. If sub-floor ventilation is adequate, and the ground under the floor is not unusually damp, perhaps there is a plumbing leak letting moisture into the underfloor insulation. If you can find the source of moisture and allow the flooring to dry out it may shrink back to a level surface. Otherwise, if it remains a problem you might need a site inspection. The Australasian Timber Flooring Association (ATFA) provides this service, more information here: https://www.atfa.com.au/request-an-inspection.

Question

We need to achieve group 2 for a timber battened ceiling. Is there anyway of achieving this without an applied finish?
Woodsolutions Answer +

All timbers we have tested fall into Group 3, no matter how dense. However, fire retardant coatings can be used on interior timber to achieve a Group 2 rating, including clear coatings for a natural finish. You will find suppliers if you search using the words 'fire retardants', 'intumescent coatings' or similar.
