Today’s hygiene regulations demand that surfaces must be smooth and easy to clean, and that walls are durable, impervious and impact resistant. The traditional approach has been to work with ceramic tiles. Unfortunately, this
can be problematic in addressing modern hygiene and durability issues.

In busy locations like kitchens, knocks to walls from trolleys, pots and pans etc are commonplace. Glazed ceramic tiles are vulnerable to damage, being easily scratched, chipped or cracked. This surface damage means that contaminated water can penetrate the tile leading to unsightly stains and bacterial growth. To make matters worse, tiles are often fixed incorrectly.


According to the Ceramic Tile Federation, this applies to 65% of all tile installations, leading to serious problems, in kitchens and showers especially. For these areas, tile manufacturers and food regulations specify the use of water-resistant adhesives and epoxy grouts. It is difficult to be sure that these have been used until, of course, it is too late and the damage has been done.

Tests show that Altro Whiterock is 100% watertight, unlike tiled surfaces.

The advent of uPVC sheet wall cladding provides a decorative and practical alternative to ceramic tiles. Being impervious, the product can be used practically anywhere. Showers and kitchens in particular benefit from the watertight, seamless, wipe clean surface that the system provides. Unlike a tiled surface there is no grout involved, so dirt and bacteria have nowhere to hide. Also, water can’t seep through to the substrate behind – a problem that can cause major structural damage to any building.

It is good for your business to invest in a long-term solution with low maintenance, less cleaning and fewer repairs.

Benefits of using Altro Whiterock.

  • - Lower Costs - Approximately 25% lower lifetime costs slightly lower total installation costs

  • - Far more hygienic – Sheets contain integral biocide which prohibits the growth of bacteria. Grout lines of tiles harbour bacteria

  • - Fewer Joints - Considerably less jointing area and no water or other penetration (into grouting and behind tiling to cause failure of wall substrate)

  • - Better impact restistance - in standardised tests

  • - Better Stain restistance - no penetration of damaged surfaces no staining of grout orpowedering

  • - Very low water vapour transmission - no penetration of damaged surfaces or grout

  • - Consistent appearance - no variations in tile shades to deal with. Sheets can be added a later date following site reconfigurations. The sheets are all UV stabilise so they will not yellow over time

  • - Better appearence retention - no staining, no grout, no replacement of damaged tiles

  • - Flexibilty to match substrate movement - no expansion joints required

  • - Easy to install - in most cases panels can be fixed direct to brick, blockwork and most substrates

Product comparison

Altro commissioned the following studies from independent bodies, to compare Altro Whiterock and ceramic tiles.

Typical installed costs


*NB Assuming typical conditions with impervious epoxy grouting, and a sand/cement scrim render over a sound substrate.

Altro Whiterock adhesive is suitable for virtually any sound substrate.

Additional costs.
This comparison does not include possible additional installation costs for tiling: drying of render 1 - 2 days; drying of tiling cement prior to grouting. (Application of Alto Whiterock wall cladding two-part adhesive, installation of wall cladding and jointing is one continuous operation.

Life cycle costs

The following chart demonstrates Life Cycle Cost relationship between hygienic PVCu wall cladding systems and ceramic tiles.



Impact Resistance

In busy locations, impacts are frequent between walls, floors and equipment such as trollies, knives or dropped loads. Glazed ceramic tiles are easily scratched, chipped and cracked under impact creating surface damage which can be infiltrated by water, stains and bacteria.

Altro Whiterock is highly resistant to impact and does not depend on a glazed surface layer for resistance to moisture penetration or staining.

Impact Tests

These were conducted using a 322g steel ball (BS EN 438) dropped from various heights on to the flat surface, join edge and corner. (Minimum height of test was 25mm).


* Maximum height of test apparatus Stain resistance

Surface damage is likely to result in penetration of materials and micro-organisms which can cause unsightly staining and act as a breeding ground for contamination. This is often very difficult or practically impossible to eliminate and will severely compromise hygiene. Test to BS EN 438-2 Section 15 involved Altro Whiterock and ceramic tiles subjected to impact by a 322g steel ball exposed to a natural fruit juice (blackberry) for 24 hours, washed and left for an hour then examined from 400mm. Visual evidence was rated on the standard's scale from 5 - 1.



Scratch resistance and water ingress

Tests were conducted on samples that were subjected to 5 hairline scratches, 5 point impacts with a dropped small kitchen knife and a combination of 3 scratches and 2 point impacts.

Water was then applied to the front face and ingress measured after 24 hours. No damage was visible on Altro Whiterock after this treatment.
