THERMAL EXPANSION
As with all decks made of wood plastic composite (WPC), UPM ProFi Deck will expand and contract with changes in temperature. The following table illustrates this effect over different temperature changes. The temperature change listed relates to the temperature of the board, not the air temperature. In direct sunlight, darker coloured boards will reach higher temperatures than lighter coloured boards.

COLOUR WEATHERING AND MAINTENANCE
Unlike other WPC and timber decks, UPM ProFi Deck is virtually lignin free, and will therefore not experience the usual "greying". Instead, over the years, the colours will fade only slightly. The picture gives an indication of the colour change that occurs during a three-year simulation of climate conditions in Northern Europe.
Cleaning with a jet hose or a normal hose and brush will help to maintain its colour. Such cleaning should be carried out periodically to ensure that surface is free of dirt and debris and that the space under the deck remains clog and clutter-free enabling water drainage effectively.
UPM's unique high-friction closed surface is very resistant to moisture absorption and therefore stains. If cleaned immediately with water after a spill, that should suffice in removing all traces. Otherwise warm water, a household detergent and gentle brushing may be used.
