Question 1 Report

A kitchen worktop must resist heat, staining and scratching and must be hygienic in use. Compare a laminated chipboard worktop with a solid granite worktop against these requirements. [4]

Answer Details

This comparison requires matching each material to the stated requirements, rather than simply listing properties.

  • Granite is far harder and therefore more resistant to scratching. A laminated chipboard surface can scratch, and a damaged laminate surface cannot be repaired easily. [1]
  • Granite resists heat from hot pans. Heat can blister or cause the laminate layer to delaminate from the chipboard. [1]
  • Both surfaces can be hygienic because they are non-porous when properly sealed. However, if a laminate edge is damaged, water can enter the chipboard core and cause it to swell. [1]
  • Laminated chipboard is much cheaper and lighter, and can be cut on site. Granite is heavy and costly, and normally requires templating and specialist cutting. [1]

Granite gives better scratch and heat resistance, while laminated chipboard offers lower cost and easier installation. In an examination comparison, make the same point for both materials, as above.
