“Thermolit” has a low density, which allows adjusting the level and angle of the base without producing significant extra loadings on the structure. The mortar is easy-to-use and possesses a high plasticity and stability, which allows producing steep slopes at a time while avoiding the risk of sagging. It quickly and easily tampers the hollows and cavities, which increases the resistance to heat transfer, and possesses high crack growth resistance and vapor permeability.

Apply the mortar to the base and spread it with a smooth metal float. Otherwise apply it between the guides and a special slat and remove the mortar surplus. The necessary slope angles are established according to preliminary installed gages. Protect the applied mortar from direct sunlight, droughts, high temperatures and low air humidity. A partial use of the fresh screed coat is allowed not earlier than in 48 hours. A full load to the screed coat and further works with new layers application are allowed in 5 days. A direct application of the vapor sealing and waterproofing to the screed coat is permitted not earlier than in 7 days of normal hardening of the mix. The temperature of preparation and application of the mix shall be within 0 … +25 °Ñ.

A prefabricated primer that fits a specific type of the vapor sealing material shall be preliminary applied to the base surface.

It is prohibited to use “Green oil” (i.e. a bitumen solution in diesel oil) prepared in the field conditions.

For vapor sealing installation we recommend using bitumen-polymer and bitumen materials with reinforcing glass or synthetic base (under STB [National Standards System of the Republic of Belarus] 1107) with a solid tipping on hot or cold mastic.

It is prohibited to use for vapor sealing any roll materials with paperboard substrate or substrates subject to rot and mould. Installation of “THERMODAH” system without vapor sealing is prohibited.

The following product types are used for “THERMODAH” heat-insulating and waterproofing roof system installation: “THERMODAH” – roll, “THERMODAH” – slab, “THERMODAH” - skirting board. The type of the products to be used is selected according to several conditions, such as the type of the load carrying structure, the class of the building as per functional fire risk, the fire resistance degree and the class of the structural fire risk in conformity with the requirements of SNB [Construction norms of the Republic of Belarus] 2.02.01 and SNB [Construction norms of the Republic of Belarus] 5.08.01.
The thickness of the heat-insulating layer is defined basing on the heat engineering calculation in conformity with SNB [Construction norms of the Republic of Belarus] 5.08.01.

When multilayer roofing is to be installed the bitumen-polymer roll materials used for the top layer of the waterproofing rug shall be produced on polyether, polyester or glass base. We recommend using prefabricated materials with dressing compound for the top layer of the waterproofing rug at the places of abutment.
