Precast is truly PRE-CAST
"The perhaps biggest advantage in using precast sandwich wall elements compared to double-wall structures and other in-situ alternatives is the speed of construction it enables", says Mr. Hannu Mononen, Export Manager at Elematic. "When the sandwich wall elements arrive to the construction site from the factory, you do not need to work on them in any way, they are accurate and ready to be installed." Always a pleasant detail for site workers as well as passers-by and neighboring residents is the cleanliness of the site when building with sandwich wall systems - no concrete mixers or heaps of reinforcement litter the surroundings, as the insulation is already in place. The fact that the installation of sandwich wall panels is so simple makes it much more convenient to build in city centers, where there is seldom room for warehouses to keep tools and materials.
Sandwich walls for a lifetime
As if these features are not enough to convince anyone of using the incredible sandwich wall system, there are even more advantages to be had. Says Mr. Hannu Mononen: "You can calculate in advance all the heat transfer properties and maximize the insulation properties for keeping the heat in or in hot climates, keeping the heat out. In northern countries this is very beneficial as it adds to the speed of erection and yet another warm floor level is finished quickly. Concrete is easy to shape and a very durable raw material - buildings can last for at least 50-100 years. The quality of raw materials increases constantly as do the insulation properties."

The quiet sandwich wall
The positive features of the sandwich wall system are also acknowledged by many construction companies. NCC is one of the leading construction and property development companies in the Nordic region with 21 000 employees and a principal of aiming to do better tomorrow, what they do very well today. NCC's Mr. Pekka Salonen has been working the construction sites for many years and says the sandwich wall system is an excellent choice. Compared to in-situ solutions, the precast sandwich wall is quick and easy to install and there are no problems with freezing during the winter time. "My unit is involved in construction projects for commercial and industrial buildings. The latest project where I was responsible was the erection of a business park. Both here and in other similar projects, sandwich wall systems are frequently used. The surface of the sandwich façade elements are often washed and polished concrete. The installation procedure is more quiet than for in-situ building and the need for workers is much reduced. From an environmental perspective, the precast sandwich wall all in all is a most positive choice."
