BEYEM AISLATERM is an ultra-light thermal insulation render, formulated with hydraulic binders, selected aggregates, expanded polystyrene, special additives and mineral pigments. Especially suitable for energy saving rehabilitation and ventilated facades. BEYEM AISLATERM is the basecoat of Beyem Aislaterm Thermal Insulation System.
Ultra-light thermal insulation render for facades and walls both in interior and exterior situations. Especially suitable for energy saving rehabilitation and ventilated facades. For exterior application in a different use than the execution of ventilated façades, it is necessary to finish with BEYEM COLORTERM, high performance one coat mortar specially designed for BEYEM AISLATERM; BEYEM NEOCAL FINO, breathable and waterproof lime mortar for facade decoration suitable for the BEYEM AISLATERM system, BEYEM THERMIDUR F extra-fine, flexible, colored mineral coating for decorative finishing of facades; PÉTREX 5 MORTERO ACRÍLICO or PÉTREX 5 MORTERO AL POLISILOXANO.
BEYEM AISLATERM is suitable for:
- Brickwork. Ceramic bricks.
- Concrete blocks.
- Concrete (treated with BEYEM UNIÓN MORTEROS adhesion promoter primer).
- Cement based substrates and cement/lime based substrates.
Substrates must be clean, compact and free of substances that reduce adhesion such as dust, oil, grease and with no loose material. Substrates must submit an adequate porosity and surface roughness. Dampen substrates with water to cool down if they should be too warm, in case of wind or over absorbent substrates and wait until the thin layer of water disappears. It is a good practice curing with a fine spray of clean water 24 h after application. Do not apply on cellular concrete, gypsum based plasters, paint, plastic, wood or materials with low mechanical properties.
Mix manually of mechanically BEYEM AISLATERM with 11,0-14,0 l per bag of clean water until a homogeneous, creamy and lump-free paste is obtained. Let the mix stand for 5 minutes before application.
To apply with render spray machine, it´s necessary to set the relation water/mortar and pump pressure depending on section and length of hose and climatology conditions.
It´s important to maintain the variables affecting the properties of the applied mortar (distance to the wall, angle of application and water proportion). Fix corners profiles and reinforcement mesh in gaps taking into account final coat. Treat conveniently the singular points. Spread the mixed product manually or mechanically leaving 20-100 mm of thickness, with a 40 mm of maximum thickness per layer. For final thicknesses greater than 40 mm BEYEM AISLATERM must be applied in different layers incorporating to the first of them complementary mechanical fixings (glass fiber mesh embedded in the mortar and fastened by mechanical anchoring once the mortar has hardened). Leave at least 24 hours to set the material between layers. Press to ensure adhesion and expel the air contained in the pores. Smooth with a ruler the applied material to regulate thickness. Expansion joints must be respected by all applied materials. BEYEM AISLATERM must be finished with any product mentioned above in case of exterior works (except in case of ventilated facades). Before overcoating, allow to dry 1 day for each centimeter of applied material (the drying time may vary depending on the weather conditions).
In the application on ventilated facades, the fasteners must be fixed on the brickwork , not in the insulation mortar.
Tools can be cleaned easily with water before the product hardens. Hardened product can be remove only mechanically.
Thermal Insulation of facade must be carried out with ultra-light thermal insulation basecoat mortar compliant with EN 998-1-Class T CSI Wc 1 such as Beyem Aislaterm, manufactured by Rodacal Beyem company. Coverage will be ≈ 3,0 kg/m2 per cm of thickness. The substrate must be clean, sound, compact and dimensionally stable. Expansion joints must be respected.
