It is highly recommended that proper design procedures are followed in use of solid surface. Following are the empirical rules that should be adhered to, while using solid surface material.
- Generally, solid surface should not used when exposed to direct sunlight. The ultra violet rays tend to fade the colouring pigments present on the surface of the material.
- may be used exposed to sun but due consideration and care must be taken. For exposed to sun; it is recommended to select one of the beige colours. Bright colours tend to yellow on exposure to UV and dark colours tend to fade. The beige colours may change its hue slightly but on sanding the top layer returns back to its original glory.
- is made of mineral fillers and resins. The physical properties of , at times, are similar to metals. With the change of ambient temperatures, Granita will expand and contract. The change of size is significant when compared to natural stone. Due consideration should be taken for this expansion/contraction. The coefficient of thermal expansion of Granita is 94.4x10-6 /ºC. This works out to about 0.1mm movement per meter per degree. In extreme climatic conditions if there is difference of temperature of 25 degrees the movement will be 2.5 mm per meter. If the allowance of contraction is not made, solid surface may crack due to stresses set by thermal strain. For a greater detail on this subject please refer to our technical department.
- Solid surface is less brittle than glass or marble or granites. However, on heavy impact it could break. To avoid this type of breaking it is recommended to use 12.7mm (½") thickness in all horizontal application. Same thickness is preferred for vertical application, however, from economical point of view 6mm (¼") may be used.
- For wall cladding it is preferred to use 12.7mm (½") thickness. But 6mm (¼") may be used. Proper care must be taken for thermal movement.
