As standard, SILKA E blocks are manufactured in very high strength classes -15 i 20 MPa. Such a high compressive strength causes, that when bricking the structural walls of a building with a thickness of SILKI E 24 cm, we can erect even 12-story buildings without an additional frame structure. The large mass of SILKI E contributes to its excellent acoustic insulation. Wall made of SILKI E24 with a thickness 24 cm plastered on both sides with mineral plaster with a thickness 10 mm has the ability to absorb sound at the level of Rw = 56 dB. In contrast, partition walls with a thickness of 8 cm they have this ability at the level of Rw = 45 dB.

Bricklaying of walls made of SILKA E sand-lime blocks is made with the use of SILKA FIX thin joint mortars.. In special cases, ordinary mortars are used to build walls from SILKA E blocks. This is especially the case when building the first layer, which should be leveled. For this purpose, SILKA WQ10 expansion blocks or SILKA E basic blocks are used.

When carrying out bricklaying works on the construction site, it is recommended to use the following SILKA tools and accessories:
• Gilotyna – for cutting blocks to the desired size,
• Table saw – for cutting blocks by a mechanical method,
• Thin joint mortar dispensers – width adapted to the thickness of the blocks: 24 the 18 cm,
• Trowels for thin-jointed mortars - width adapted to the thickness of the blocks: 24,18,15,12 the 8 cm,

Specialized, ready-to-use mortars for silicates with increased water retention. SILKA FIX mortar 10 has an average strength after 28 days worth 10 MPa. A winter version of the mortar is also produced – FIX WIRE 15 WITH. It allows you to carry out bricklaying works from the temperature of 0 ° C. The mortar setting process runs smoothly, even after the ambient temperature drops to -5 ° C.

The SILKA construction system has several important features. It is manufactured on the basis of a height module – 20 cm and manufactured with high dimensional accuracy (tolerance ± 1mm). We put a layer of cement mortar on the marked line. In damp rooms, we put a strip of insulating foil on the mortar. We set the first layer of blocks very carefully, checking their position with a spirit level. This allows the use of a maximum thickness of thin joint mortar in subsequent layers 2 mm. On the wall, to which the future wall is to adjoin, we put to the height 25 cm thin layer of mortar for thin joints.
