An expansion gap of at least 10 mm (about 0.39 in) is required, unless the room is climate controlled. In a climate-controlled environment this can be reduced to 5 mm (about 0.2 in). Use spacers around the perimeter of the flooring area during installation. Remove spacers before the trim is installed. Ensure the expansion gap is clean of all debris before installing trim and that the trim rests upon the TIER boards to prevent debris collecting in the expansion gaps.

Remember to also leave expansion gaps whenever the floorboards meet an obstruction, such as pipes, columns, fireplaces, door jams, and even unusually heavy loads. Undercut door jams to create a seamless finish between the frame and the boards, whilst maintaining an expansion gap below the frame.

TIER floorboards are suitable for Grade 1 floor installation; permissible deviations should not exceed 3 mm (about 0.12 in) at any point in a 10-foot run. Most tiled floors will not comply with these conditions.

We recommend that a standard or self-levelling screed is done prior to installation of your TIER product.

TIER flooring is scratch resistant and will not scratch under normal use and with basic upkeep, such as sweeping or vacuuming loose debris. However, we recommend using felt pads beneath furniture. If you plan to move heavy furniture, lift the furniture when moving it.

Sweep or vacuum loose debris regularly to prevent sharp particles from being trodden into the surface. For everyday cleaning, mop your TIER floor using a low concentration mixture of water and dishwashing liquid, with a tightly wrung out mop. After mopping the surface, remove any excess water. For stubborn dirt, a low concentration of white vinegar and water may be used. No polishes or waxes should be applied to the product.

Robotic vacuum cleaners and robotic mops can be used on TIER flooring. However, do not use industrial floor cleaning equipment which employs an aggressive brush or similar process, as it may damage the TIER flooring wear layer. Similarly, a domestic steam mop, used under normal conditions, may be used on TIER flooring, but not industrial steam mops which may omit an excessive amount of water, have abrasive pads, and use excessive heating for drying. *Please refer to our Cleaning and Care Guide for more information.

TIER flooring can be installed over areas of up to 1000 square feet, or in running lengths of up to 32 feet, without the need for an expansion joint. Again, in a climate-controlled environment this can increase up to 2000 square feet or in running lengths of up to 64 feet. Use appropriate expansion joints for areas or lengths greater than this. *Please refer to our Installation Guide for more information on this.

We do supply matching accessories for TIER Element PVC-free flooring. These are available in 5 different moldings matching the floor color of your choice.

TIER flooring can be installed in areas exposed to sunlight or UV rays. TIER floorboards offer a UV-resistant ceramic coating to prevent the color of your floor fading significantly.

Do not install TIER flooring in areas that are constantly wet. Although TIER flooring is highly resistant to water absorption, no product is completely impervious to water. “Waterproof” is a standard term used in the flooring industry, but this means the product passes the relevant moisture absorption tests. *Please refer to the TIER Technical Data Sheet to understand the moisture absorption test results.

The joints between TIER floorboards are designed to be watertight. However, water may seep through these points when subjected to large volumes of water for extended periods of time. Water may also seep around skirting, trim or reveals. Although the TIER floorboards, themselves, will not be damaged, water below the floorboards can result in uneven distribution of loads and may damage joint profiles between boards.

If water does seep below your TIER flooring, remove the boards, allow the subfloor and the floorboards to dry completely and then re-install. Do not leave water below the floorboards. Mop up any pooled water promptly.

Yes, provided the design and installation of underfloor heating is within the confines of the subfloor and done by a competent professional to ensure no impact on the stability or level of the subfloor. The screeded surface finish cannot be affected by the under-floor heating elements.

TIER utilizes an IXPE underlay. This provides great thermal insulation and is suitable with underfloor heating, however, the underfloor heating is not permitted to come into direct contact with the IXPE layer on the underside of the TIER floorboards.
