Thermally insulate a façade with the Term 50 mineral finish system

Share this solution

Using a light thermo-insulating mortar for an External Thermal Insulation System is a highly innovative alternative with proven efficiency compared to the expanded polystyrene (EPS) system or mineral wool (MW).

Facades of new plant must comply with the energy constraints imposed by the current Technical Building Code (CTE).

The high insulation capacity of the mortar PROPAM® TERM 50, with a thermal conductivity = 0,05 W / m.K, allows to reduce the energy consumption and to improve the comfort and the well-being of the user of the house.

Through the SISTEMA TERM 50 thermal bridges are eliminated, and the risk of condensation inside the house, thanks to its high vapor permeability, with a water vapor diffusion resistance factor μ ≤15.

Continuous application, allows thicknesses between 20 and 80 mm, adapts perfectly to any geometry of facade, providing a solid thermal insulation, non-discontinuous, with different finishes and excellent mechanical resistance to impact and punching.

It allows to reduce the costs of construction.

The system consists of:

  1. Mortar PROPAM® TERM 50
  2. Finishing cladding REVAT® MINERAL

The support must be stable, clean of dust, paint, oil, etc. Do not apply to traces of plaster.


Prepare the support using the appropriate rules that allow to delimit the total thickness of the Thermal Insulation System (PROPAM® TERM 50 + REVAT® MINERAL) and the size of the surface to be applied.

Apply PROPAM® TERM 50 by mechanical projection. It can also be applied with trowel in areas where it is difficult to use the projection machine. The consumption is about 3 kg / m2 and cm of thickness.

Use a regle to achieve a flat and stable surface.

When the application thickness is between 40 and 80 mm, apply PROPAM® TERM 50 in two layers of equal thickness each of them. The first of these layers must incorporate 10×10 mm (alkali resistant) glass fiber mesh, which will be embedded in the mortar base with the aid of a trowel.

After 24 h, fix the mesh with mechanical anchors (plastic tails AISTERM ISO 10×90).

The second layer should be applied once the first layer has dried (1 day per cm of thickness).

To make the finishing coat, wait until it dries PROPAM® TERM 50 (1 day per cm of thickness).

Apply REVAT® MINERAL reinforced with fiberglass mesh directly on PROPAM® TERM 50. Once finished, the recommended thickness for this layer is 10 mm.)

He SISTEMA TERM 50 admits also other finishes: acrylic mortar (REVAT® PLAS), flexible lime stucco (REVAT® CAL FINO) and ceramic coating; for any of these finishes it is necessary to apply a double layer of PROPAM® AISTERM with mesh AISTERM N-N3625 (centered on the thickness), on the surface of PROPAM® TERM 50.


It should be applied between 5ºC and 35ºC. In hot weather or dry wind, the substrate must be moistened with water. For the application of the SISTEMA TERM 50 with a ceramic finish, it is necessary to study the specific characteristics of each work in advance and consult with the manufacturer the appropriate placement method according to the elephant tile format. As a cementitious adhesive in this type of finish, it will always be used PAM® SUPERFLEX COMPACT (C2TES2), highly deformable and high performance ecological adhesive.
