Go term 39

Go term 39 hollow brick was developed in line with new knowledge and construction requirements for the construction of low-energy buildings. The hollow brick has a modern design, which enables a quicker construction and a lower mortar consumption. It is intended for the construction of load-bearing outer walls with a thickness of 39cm and increased thermal insulation capabilities of the constructed wall.
Due to the particular design of vertical sides, two pocket openings are created in the centre of the joint of two hollow bricks, which are filled with mortar. The mortar is not visible from the outside. The mortar in the vertical joint is also not in direct contact with the external plaster. The core of the element are longitudinal and transverse walls, which together form a system of shifted holes. The element also has two large holes which enable simpler grasping of the hollow bricks and installation of the bricks into the wall. External walls are slightly serrated, which enables a better mortar hold.

Advantages:

• Guarantee for high heat accumulation of the wall.
• Better soundproofing insulation: 60 dB *  (*plaster on both sides of the wall - thickness of plaster 2.5–3.0cm)
• The tongue and groove joint (additionally reinforced wall at the vertical joint, prevented thermal bridge).
• Excellent compressive strength of 22 MPa.
• Smaller mortar consumption (fewer thermal bridges). Mortar consumption (theoretical):  67l/m², 167l/m³ 
• Thermal conductivity: 0.22W/mK  (*constructed with thermal mortar)
