Heat Insulation Composite System: Various Insulation Materials For Different Requirements

Costs accompany a client not only during the planning and construction phase of a property, but also in the form of energy and maintenance costs.Heat Insulation Composite System

Since these can occur in the complete course of the utilization phase and can generate correspondingly high sums, measures should already be taken in the planning phase to prevent possible cost-eaters.

Such cost guzzlers are, for example, heating costs. These are due to heat losses of an unnecessary type, eg due to insufficiently insulated exterior walls of buildings. Here valuable energy is lost.

The installation of a heat insulation system (short: ETICS) is a recommended measure to save heating energy and the resulting high energy costs.

Construction of an ETICS system

ETICS systems are basically suitable for all substrates and always have the same structure:

  1. Klebemörtel
  2. insulation
  3. dowel
  4. Armierungsmörtel
  5. tissue
  6. plaster
  7. Colour

System suppliers such as bausep.de offer this construction only in the form of a complete kit, since the individual components are optimally coordinated to achieve the desired effect. Adhesive mortar, dowel, reinforcing mortar, fabric, plaster and paint are fixed components which do not allow any room for maneuver. At the core of the ETICS, the insulation material, there are different variants from which the user can choose: Styropor®, stone wool and wood fiber. Each variant has its own special advantage. This means that in the course of the planning phase, it is important to consider the advantages to be gained from, or the priority to be made.

Variant 1: Cost-effective ETICS with Styropor®

Styropor® is the trade name of EPS (expanded polystyrene rigid foam) and is one of the best known insulation materials. The decisive factor that makes this variant particularly attractive is clearly the price. This is much cheaper compared to stone wool and wood fiber. In addition, the material convinces through further properties. With the assignment to the heat conducting groups 032, 035 or 040 can be a good thermal insulation effectbe achieved. The legal, structural fire protection requirements are also covered by the classification to fire protection class B1, which indicates a high degree of flammability, or B2, which implies normal flammability. The low weight of Styropor® is reflected in several advantages. Thus, the material is easy to transport, process and easily fastened with the appropriate adhesive or suitable dowels.

However, some disadvantageous properties are also to be weighed. The production of Styropor® is very energy-intensive and therefore burdensome for the environment. In addition, the material is irremovable, which makes disposal more difficult. For this, too, a certain energy expenditure is again necessary. Despite the acceptable fire protection properties, the polystyrene releases harmful substances in the event of a fire, which can impair the health. Compared to stone wool and wood fiber, EPS has a higher density, which increases the risk of mold formation.

Variant 2: ETICS with improved fire and noise protection with stone wool

The use of stone wool as a core element at the ETICS is convincing above all by the excellent fire and noise protection properties. With the assignment to the fire class A1 and a melting point of over 1000 ° C, the material is considered non-combustible. The Steinwolle owes its very good properties in the field of noise protection to its weight per unit area. This is significantly higher than eg the weight of polystyrene and thus prevents the spread of sound. At the same time, it also makes processing and assembly difficult. In order to mount a stone wool insulation panel, a two-layer mounting is necessary: the panel must be glued and dowelled. This means that not only the plates are more cost-intensive than eg Styropor®, but also the required additional material.

Variant 3: Ecological ETICS with wood fiber

Wood fiber as a third variant is the ecological solution in the case of ETICS. In combination with a mineral plaster and a mineral paint for the paint, a diffusion-free construction is achieved which prevents mold formation.

The high compressive strength of the insulation panels has a positive effect on the thermal insulation. Due to the high weight, the processing is somewhat more powerful, but this is compensated by the edge processing in the form of tongue and groove, which allows easy and fast joining of the plates.
