Wall tiles do not present too great a problem in that once fixed, the tiles will perform

Bernard Arnull have some 50 years’ experience in the field of Ceramic Wall and Floor Tiles, and are happy to advise on choice of tile, installation techniques and maintenance.

Wall Tiles

Wall tiles do not present too great a problem in that once fixed, the tiles will perform. However, if fixing wall tiles externally some thought must be given to the weight of the tile, its fixing bed and method and to whether a vitrified tile should be used.

Bernard Arnull supplies tiles for all types of specified projects ranging from distinct high quality residential developments to restaurants, retail, leisure and hospitality projects

Select through – body or doubled – loaded porcelain tiles which achieve the heaviest wear characteristics

Floor Tiles

Floor tiles are rated with a PEI scale of between 1 and 5, 5 being the heaviest duty tile. The MOHS scale also rates tiles as far as a hard-wearing surface is concerned, and here again the higher the number, the stronger the tile.

We would recommend that only PEI 5 grade tiles be used in heavy wear and Public areas. Most porcelain tiles achieve this wear rating, though care should be taken to select through-body or doubled-loaded porcelain tiles which achieve the heaviest wear characteristics. Whilst this does restrict colour choice to some degree, although this is being improved by new production techniques. However, it is far better to specify a tile that will achieve its intention than use a colour which will not. Recent technical developments have seen single-fired tiles replaced with glazed porcelain tiles, which have a glaze on top of a porcelain base. This base though is not necessarily the same colour as the face of the tile and incorrect use can cause problems. Polished porcelain tiles, on the other hand, are more than suitable for heavy wear areas and a a stunning effect can be achieved. We have supplied these to many restaurants with great success.

The latest ink-jet production technology has greatly widened the appeal of porcelain tiles as opposed to natural materials, although care must be taken in ensuring the correct heavy duty tile is used.

Slip Resistance

Another area of concern is non-slip tiles. It is worth remebering that as a rule the greater the anti-slip finish on the tile, the harder it is to keep clean. There are specific slip resistance tests carried out on tiles which grade a specific tile for its suitability to given conditions.

DIN 51130 classifies tiles with ratings of R9 to R13 for slip resistance:

R9Suitable for 3° to 10° slopes
R10Suitable for 10° to 19° slopes
R11Suitable for 19° to 27° slopes
R12Suitable for 27° to 35° slopes
R13Suitable for slopes above 35°

DIN51097 classifies tiles from A to C non-slip suitability fin wet areas:

A> for a slope up to 12°
B> for a slope up to 18°
C> for a slope up to 24°

Pendulum Skid Resistance which also gives the following rating which applies to both dry and wet tiles:

Rating <25Very Slippery
Rating 26-35Average
Rating 35-65Good Skid Resistance
Rating 66+
Excellent Skid Resistance
