Thermal insulation



The temperatures for outdoor works usually range from +5 to + 25˚C, but unfortunately autumn and winter in our latitudes is a variable temperature that goes around 0˚C. Not everyone knows, but these temperatures do not only affect the air! Also built-in materials, substrate and mixing water! Temperatures> 5˚ provide very good conditions for binding hydraulic binder, i.e. cement.Of course, it is possible to carry out work at temperatures <5˚C, but working at temperatures between 0˚C and 5˚C will result in longer cement setting time and even a lack of cement. It will not destroy such a product, the technical properties of the material will probably be preserved. Unfortunately, aesthetics probably do not. Working at low temperatures with traditional materials, in addition to high humidity, increases the risk of salt efflorescence. Even included routes, special accessories etc. will not help here. Temperatures close to 0 ° may cause freezing water, which can lead to material damage.

The temperatures for outdoor works usually range from +5 to + 25˚C, but unfortunately autumn and winter in our latitudes is a variable temperature that goes around 0˚C. Not everyone knows, but these temperatures do not only affect the air! Also built-in materials, substrate and mixing water! Temperatures> 5˚ provide very good conditions for bonding hydraulic binder or cement. Of course, it is possible to carry out work at temperatures <5˚C, but working at temperatures between 0˚C and 5˚C will result in longer cement setting time and even a lack of cement. This will not destroy such a product, the technical properties of the material will probably be preserved, unfortunately the aesthetics probably will not. Working at low temperatures with traditional materials, in addition to high humidity, increases the risk of salt efflorescence. Even included routes, special accessories etc. will not help here. Temperatures close to 0 ° may cause freezing water, which can lead to material damage.

Dispersion products such as: paints, ready plaster mixes for proper bonding require a temperature of> 5 ° C, because these materials bind by evaporating water. Work at low temperatures and high humidity will cause the plaster, the paint does not dry out and with the first major rainfall will flow with it. Therefore, you should wait for favorable weather forecasts or use special heaters that will raise the temperature to the required temperature, but at the same time increase the costs of such a system.

Rescue of these problems can be special "winter" products, which enable work in temperatures from 0˚C to 5˚C and they are not terrible at night temperature drops below 0˚C. They allow you to calmly carry out works in the autumn and winter. A new autumn in the KREISEL offer, the TURBO Z-SA system is such a system. The TURBO Z-SA system is intended for thermo-modernization of existing buildings in both single-family and multi-family and industrial construction, as well as for thermal insulation of newly-constructed buildings. Due to specially developed recipes, it allows you to perform insulation work at reduced temperatures. The system includes: winter LEPSTYR Z 211 adhesive mortar, STYRLEP Z 221 winter adhesive-joining mortar, TYNKOLIT Z-SA winter plastering primer 341, SILIKATYNK Z 021 winter silicate plaster.

During work with this system, the outside temperature of the air, the substrate and the material to be incorporated must not be lower than 0 * C, this temperature must be maintained for at least 8 hours, after which time the temperature drop below zero is acceptable.

As a finishing layer, a special silicate plaster SILIKATYNK Z 021 was used. Thanks to the silification process, the plaster is chemically combined with a mineral substrate such as STYRLEP Z 221 mortar, which translates into an extremely durable inter-layer bonding. This is extremely important especially in performing work in difficult conditions. SILIKATYNK Z 021 is produced on the basis of potassium water glass. Silicate plaster combines the advantages of mineral (vapor-permeability) and acrylic plaster (high mechanical strength) while removing their defects (efflorescence on mineral plasters, fouling of acrylic plasters). The contained potassium glass causes the pH of the solution to increase to 11.3, thanks to which the expedition is highly resistant to algae, algae, fungi, etc., i.e. biological aggression, as well as to industrial pollution. These plasters have high vapor permeability and CO2 permeability, comparable to mineral plasters. The plaster is available in three 1.5mm grain thicknesses; 2.0mm and 3.0mm with textures of lamb and scratched.

But remember that in addition to high-quality materials, the basic implementation rules are important, that is: pay attention not to paint or plaster on damp ground (dew) which often cause the flow of paints and plasters and color differences, do not incorporate frozen materials, or on wet or frozen substrates. Finally, remember to read each instruction of use and check whether the product has no possible special recommendations.

The TURBO Z-SA thermal insulation system is compliant with PN-EN 13499: 2005 "Thermal insulation products in construction. Exterior composite thermal insulation systems (ETICS) with expanded polystyrene.
