The Optimal construction system is traditional building, but the highest quality. SOLBET Optimal is used for external and internal load-bearing walls as well as for filling walls. External walls with a block in Optimal require insulation with mineral wool or foam. Optimal blocks can be profiled with floor and groove. The mounting bracket is always standard. When masonry with blocks, vertical joints are not filled. The consumption of adhesive mortar compared to a block without profiling is also smaller. These blocks are usually built on thin-layer mortar, because they are made with one-millimeter dimensional tolerance. Thanks to this, the masonry time of the load-bearing layer of the sandwich wall is reduced. Blocks 30 cm thick are ideal for erecting buildings in utility or non-insulated garages, for example. 24 cm wide blocks can be insulated. This results in a light wall structure.
