BauSATEi® is a system designed for the rehabilitation of the thermal envelope of buildings. It improves its thermal insulation in order to achieve a comfortable interior temperature throughout the year. The resulting energy savings can reach 50 KW-h/m2 year depending on the selected insulation thickness, and allows obtaining the green zone of the Energy Efficiency Rating (A, B and Zero Consumption).
BauSATEi®, Thermal Insulation and Structural Rehabilitations
Aislamiento Térmico Exterior e Interior
100 times more resistant that conventional SATE solutions.
BauSATEi®is made up of a folded expanded polystyrene plate, with a steel mesh attached to it by means of 40 connectors each m2.
The thickness of the plate can vary between 30 and 300 mm depending on the insulation requirements of the building and its density corresponds to Class III: 15 Kg/m3, with a thermal conductivity U = 0.037 W/m K.
It is completed on site by applying a layer of concrete with a compressive strength greater than 16 MPa and an average thickness of 20 mm,
which gives it its characteristic strength.
Provides great savings in heating and air conditioning costs by reducing the U value of the building’s thermal transmittance.
BauSATEi® is the result of the research carried out by the Baupanel® System R+D+i department to improve everything that exists to date in terms of external thermal insulation systems , commonly known in Spain as SATE systems.
Conventional ETICS solutions have very low impact resistance (3 joules) making them very vulnerable to natural wear and tear and accidental or intentional damage.
BauSATEi® is 100 times more resistant (300 joules) since it has been developed from an expanded polystyrene plate reinforced with a high resistance galvanized steel mesh; the zig zag profile of the plate allows to accommodate a robust layer of micro concrete.
Designed for the rehabilitation of thermal building enveloping.
It is also noteworthy that the folded shape of the BauSATEi® insulation plate, based on the façade to be rehabilitated, interposes a series of mini channels that constitute an air chamber without ventilation, providing greater resistance against infiltration.
How do you install the panels?
BauSATEi® is anchored to the facade either by polypropylene studs with nylon nails or with 6 mm diameter corrugated steel bars. The number of fixings required is given by mechanical calculation applying the criterion of the CTE-DB-SE-AE, particularly section 3.3 where the wind forces are collected according to geographical location, degree of roughness of the environment, height above sea level, and the shape and orientation of the facade. Usually 5 fixings per m2 are required.
Once the panels have been placed and anchored to the façade, the application of the micro concrete layer will be applied with 15 mm masters placed on the steel mesh. Taking into account the depth of the board (10 mm) and the diameter of the steel mesh elements (2.5 mm), this layer acquires the average thickness of 20 mm. Concrete is applied with a projecting machine and can be finished with a mechanically smoothed concrete finished.
The finished surface can be completed as indicated in the project by painting or plastering acrylic mortar.
¿Why using BauSATEi®?
Advantages of Thermal Insulation BauSATEi®
High resistance to impacts
It is 100 times more resistant (300 joules) than traditional SATE systems (3 joules).
High resistance to bending
BauSATEi® is 25 times more resistant to bending than traditional SATE systems.
Secured assembly
It can be fixed with steel bars, given the greater thickness of the resistant layer.
It incorporates an air chamber
BauSATEi® improves resistance to infiltration by means of an air chamber.
Reduce assembly time
The plates of up to 4.4m2 that simultaneously incorporate the insulating element and the resistant reinforcement, provide greater installation speed.
Simplify Building Construction
Only two operations: fixation of the plate and subsequent application of the resistant layer, while traditional ETICS consist of at least six operations for assembly.
Does not spread fire
The BauSATEi® expanded polystyrene insulating plate is Euroclass E, hardly flammable, so it does not spread the flame in case of fire.
Energy savings
BauSATEi® provides great savings in heating and air conditioning costs by reducing the U value of the building’s thermal transmittance.< /span>
Energy Savings and Environment Impact
Currently the construction sector is responsible for 40% of consumption of worldwide energy production.
In addition, the sector is responsible for 25% of the waste generated in the world.
However, BauSATEi® has as its main component expanded polystyrene (EPS), an efficient, effective thermal insulation material that plays an important role in reducing CO2 emissions to the atmosphere, making a very positive contribution to the reduction of global warming. In the production of the EPS CFCs or HCFCs are not used as foaming agents, so that their manufacture does not cause any damage to the ozone layer.
During the useful life of a building built with BauSATEi®, the need for external energy input is significantly reduced, resulting in a lower consumption of fossil fuels, which in turn leads to a lower emission of CO2 into the atmosphere.
For the purposes of the Energy Certification of Buildings, which is a requirement derived from Rule 2002/91 / EC, and from Rule 2010/31 / EU, BauSATEi® is an efficient construction system that allows achieving the highest energy rating [class A] at an affordable price. This is due to its enormous thermal insulation, which is an added value for both developers and end users that will appreciate the reduction of their energy consumption bills.
Properties of Expanded Polystyrene (EPS)
Expanded polystyrene is a biologically inert, non-toxic and stable material.
It does not contribute to the formation of methane gas or provide any other potential greenhouse gases. Furthermore, its waste does not pose any risk of contamination to groundwater.
Expanded polystyrene is 100% RECYCLABLE. During production of the BauSATEi® panels, virtually no EPS waste is produced, because the little waste resulting from cutting the blocks is recycled directly in the same production plant.
The polystyrene used for BauSATEi® panels is the self-extinguishing type, that is, the material does not propagate flames.
