Cupping, peaking and crowning all relate to curvature across the board face – where the board edges are either higher or lower than the centre of the board. In the case of peaking and generally with cupping, the board edges are raised; and with crowning, board edges are lower.

Cork is a durable and natural material with unique properties that make it desirable for flooring. The nature of cork (the bark of a tree) is that it has many enclosed air cells and contains the substance suberin that naturally repells moisture.

Firstly, it needs to be considered that there has been a tradition of solid timber flooring in houses being repaired. Old floors of perhaps 20 or 50 years have often had repairs for many reasons including squeaks, termite damage or water damage.

Traditionally, flooring was held in place by nailing it to the subfloor surface. Floating a floor is an installation system which originated in Sweden in the late 1970s with the development of Pergo, a reinforced laminate flooring product.

Firstly, we need to consider solid timber flooring and how it shrinks and swells with changing relative humidity. This is shown in the adjacent diagram with board expansion occurring under higher humidity conditions and board shrinkage under lower humidity condition.

As the colder months approach us in autumn of each year, that familiar inkling to turn the heater on at night creeps back in. Before you know it, winter is in full swing and the heater is running for half the day and most of the night.

An essential part of timber deck design is to evaluate and include the necessary ventilation. This aspect is not always fully covered by timber supplier…

With solid timber floors the topic of gapping at board edges and the possibility of filling those gaps is a subject often raised.

Ever since there have been timber floors, seasonal movement has been observed where floors would shrink during drier weather and expand during more humid weather.

For as long as there have been timber floors there have been squeaks and it is generally accepted that many floors will make some noise when walked on.

When the wet weather has been more intense than previous years we have seen expansion pressure in floors take its toll.

Both wood-based and vinyl-based flooring can be installed over underfloor heating and in recent years owners in the cooler southern states of Australia and in New Zealand are more frequently including this heating option in their dwellings.

Australia has a long tradition of common names for species, and ‘blue’ gum is a prime example where there is a ‘blue’ gum in at least three states and each is a different species.
