One of the most important problems nowadays is energy efficiency securing. In the present paper thermal insulation materials were designed, their mechanical and insulation properties were optimized. Special attention is paid to the peat, wood processing industry and agricultural by-products which are used in composite production. The activation of the raw materials allows not only to improve existing properties and open the new ones but also to make greater use of natural resources. Variety of the insulation materials was obtained using peat glue as binder and using different fractions of the wood chips, peat and hemp as fillers. For obtaining the peat binder, mechanically-thermal activation was applied using planetary ball mill in the water environment. During the research various insulation building materials were obtained: peat glue was used as a binder and various fraction wood chips, hemp sheaves and peat – as filler. The obtained materials and products are:

- The activated peat that can be used as a binder,
- Peat-Wood/Hemp insulation panels with density 150–300 kg/m3, thermal conductivity from 0.050 to 0.065 W/mK;
- Peat-Wood/Hemp composite with resistance to compression of 1 MPa.
