Which loose connective tissue works as an insulator of the body’s heat?

Loose connective tissues have cells and fibers loosely arranged in a semifluid ground substance. These tissues are of the following two types: 

1. Areolar (tensile strength and protective tissue) 
2. Adipose (fat-storing tissue)

Adipose tissue is present under the skin and stores fat. It acts as a shock absorber and helps in maintaining body temperature in colder environments.

Skeletal tissue and vascular tissue are the examples of specialised connective tissue.
