GUIDELINES

COLOUR VARIATION & CHANGES

Timber is a natural material and variations in color, texture and other naturally occurring features occur between pieces and batches of the same species. Sanding and finishing also causes variation in appearance. Care should be taken in making a selection based on a single sample. In all cases timber flooring supplied in job lot quantities will contain some variation from job to job and from the sample on display.

Timber flooring whilst dried during Production, continues to take up moisture during its life, depending on weather and local conditions. In so doing, some movements and changes to the surface of your floor are to be expected and will be apparent.

Timber floors become more beautiful with age. Like all natural products timber floors will experience subtle color changes over time. Two factors that will contribute to this: sun exposure and the finish that is applied to the floor over time, prolonged sun exposure will cause timber floors to change color. You can minimize this effect by having window coverings, moving rugs and furniture to limit the exposure The second factor is the floor finish: Oil modified finishes will a mber overtime, giving the floor a slightly yellow appearance. In contrast water based finishes will remain clear over time, minimizing long term color change.

 

HARDNESS

Depending on whether your timber floor is for commercial or domestic purposes, you may need to consider the hardeness of the floor. Hardwood Timber Floors have a Janka Rating. This is a system used to measure the Hardness of the Timber. It measures the force needed to drive a steel ball to a depth where half the ball is imbedded in the timber. The more resistant the timber the higher the Janka Rating.

MOISTURE CONTENT

Moisture content should be in a range 9 -14%. The best way of bringing flooring to the appropriate moisture content at a particular site is by acclimatizing it to the conditions of the site. Successful acclimatization relies on the temperature humidity and on site Conditions.

Profile Timber Floors delivers with Moisture Content of between 9-14% to suit most Victorian Climates as per AS 27961.

Acclimatization is usually for 10-12 days. Acclimatization is process by which a board's moisture content reaches the moisture content of the site. Once Profile Timber Floors has verified that the timber has come to "equilibrium moisture installation of timber floor will then follow.

For further references on Acclimatization and Moisture Content consult the relevant Australian Standards.

 

VENTILATION

To achieve satisfactory long-term performance from a timber floor, it is essential that correct sub-floor drainage and ventilation be in place. Ventilation provides conditions beneath the floor that are similar to external conditions. If there is inadequate ventilation and higher than normal levels of humidity occurs in the sub floor, this is likely to manifest into expansion and cupping problems in the floor.

 

GRADING

Timber is graded according to AS 2796 Timber - Hardwood - Sawn and Milled Products including AS2796-1 Product Specification and AS2796-2 Grading specification.

 

SELECT GRADE (to AS 2796)

The features that are present are relatively small and few in numbers. Irrespective of the species the features although visible do not dominate the appearance of the floor.

 

STANDARD GRADE: (Medium /Feature to AS 2796)

This grade contains boards that may be moderately featured. Where Gum veins are more prevalent in a species considerably more character is provided to the floor and may look quite dominate in light colored species.

 

FEATURE GRADE: (High Feature Grade to AS2796)

Feature is more frequent and dominate.

 

LENGTHS

Unless otherwise specified lengths will vary from 900mm to 6m for 19mm timber Flooring.

Unless otherwise specified lengths will vary from 900mm to 3.6m for overlay Flooring.

 

ORDER QUANTITY

Profile Timber Floors recommends that you allow an extra 5 - 10% when you order your timber to allow for wastage when cutting timber to size and laying in specific areas.

 

CHECKLIST when ordering TIMBER flooring for your project
