There are not many materials available that contract on heating. In fact contraction on heating is a rare phenomenon. In most cases, the contraction that is observed is not because the material is contracting due to heat, it is because the material is changing phase and turning to liquid or gas which gives it a feeling that it got contracted.
 
However, here is a list of materials that contract/appear to contract on heating
 
Hair, rubber, plastic, water, leaves, paper, cloth
