Quartz Comparison: Unistone VS Silestone

Unistone is a compound quartz stone which is highly resistant and sturdy, made up of approximately 93% pure quartz crystals. The material is the perfect surface to use for walls and floors, kitchens and bathrooms. Obtainable in 41 diverse colour-combinations, Unistone is a material appropriate for all types of kitchen interiors and designs. It is vital not to expose the surface to certain types of strong solvents, as it is made up of aggregate-resins and grains. Unistone quartz should also be treated with care. It does not stimulate bacterial growth, as the surface of the material is antibacterial. Unistone has a non-porous characteristic, thus protecting and fighting against stains produced by wine, vinegar etc. From kitchen worktops to furniture designs, Unistone Surfaces provide a wide range of designs and patterns, presenting a wide array of decorative possibilities to interior designers, architects and design aficionados.

Should a manufacturing defect be found on any of its products, the process of raising the claim is like that of most branded stones such as the one for Unistone, albeit in a more controlled fashion: You would contact your stone fabricator who would in turn contact Silestone. As Silestone is both the manufacturer and distributor of the material, they have the ability of allocating a representative to attend the site, carrying out the inspection of the surfaces. The findings are then reported to headquarters, who issue a final report with results directly to your stone supplier.

Whilst when working on larger projects Unistone may work out more cost effectively, for smaller projects, Unistone may cost the same, or sometimes more than Silestone, since bringing the materials from the distribution centre in Birmingham carries a cost which may make an impact when purchasing small quantities of the product. Unistone has a distribution centre in Midlands and Silestone has several distribution centres all over the UK with their own teams of representatives, customer service and technical member of staff. With bigger brands such as Silestone, the delivery of materials usually takes place more often, resulting in quicker installation times as well as in quicker resolutions when customer service is required to attend manufacturing faults and defects.
