Economical standard grade for general purpose use. Also suitable where sheet may come into contact with food.


Extruded semi-rigid PVCu sheet.

Surface finish:

Maximum service temp:

2500 x 1220mm (W103)
3000 x 1220mm (W104)
3.6 kg/m²

Altro Whiterock W103/104 PVCu extruded sheet is supplied with a protective film on its face which can be left in place until the room is ready for use.
This also helps to protect the surface from dust while other trades are in the area. It is ideal for applications requiring a hygienic easy-to-clean, almost maintenance free wall finish, which conforms to UK and European hygiene requirements.

This is the most economical standard grade which can be used for the majority of installations.


The sheets can be fixed directly to most dry substrates depending on its surface suitability, using one of the following methods:

  1. AltroFix™ W139 fully bonded system
  2. AltroFix™ W157 fully bonded system


Cutting to be carried out using a fine tooth circular saw with TCT cutting blades and pressure guide, fine tooth blade jigsaw, a fine tooth handsaw, a high speed TCT router.


- see relevant detailed drawings

  1. A high impact extruded PVCu ‘H’ joint trim (available in two part or single part for use in secure units), incorporating a watertight seal at the mouth of the joint, which is unique to Altro.
  2. Colour coordinated Altro Whiterock FlexiJoint™. (Not for use in secure units).
  3. Hot welded joint colour coordinated w/rod.
  4. Silicone sealant 3mm joint.
  5. A powder coated aluminium “H” joint used for extra impact or heat resistance.

Internal / external corners

- see relevant detailed drawings, available on the Altro Website; www.altro.com
Altro Whiterock is normally thermoformed on-site, internal and external corners including window and door reveals are neatly clad, omitting the need for corner trims. However, profiles are available for these junctions if the need arises. Vulnerable external corners are usually over-clad with stainless steel corner protectors, to a height of 1200mm.


Regular cleaning using a soft cloth and a suitably diluted mild detergent is all that is normally required. Stubborn marks can be removed with Altro Cleaner A859 or nonabrasive domestic type cream bath cleaner.
Do not use abrasive pads or wire wool. Do not clean above 60°C. Cleaning cards are available on request.

Chemical resistance

Resistant to a wide range of chemicals, specific details on request.



Storage & conditioning (on-site)

Sheets should be stored flat, fully supported and left for 24 hours to attain the ambient room temperature prior to installation (min 14°C).

Limitations of use

Altro Whiterock W103/104 has a maximum working temperature of 60°C. For temperatures above this use stainless steel. Stainless steel must be used for all open flame areas (available cut to size) must be extended to min 300mm past heatsource. If a layout showing the position of equipment can be supplied, we will provide specific advice as to the best combination of materials to use.

Typical applications

  • Commercial kitchens
  • Laboratories
  • Pharmaceutical areas
  • food manufacturing areas
  • shower / toilet / changing room areas
