Warm and green house

Green Building - construction that increases the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment. May be accomplished by applying these requirements to siting, design, construction, operation, maintenance, and removal — encompassing the entire building life cycle.

Now in modern high-tech era, when  a wide variety of building materials are offered, traditional clay bricks still retains its position among building materials and occupies pride of place. Particularly appreciated features such as their ability to accumulate and even give away the heat, ecology and naturalness. In our climate ceramic bricks equally well can withstand and the winter frosts, and summer heat.

Ceramic blocks are a natural mineral ecologically pure product obtained using natural raw materials and simple production technology.

The main clay in raw materials is a product of degradation of various minerals (kaolinite, montmorillonite, hydromica, nontronite) and crystal rock obtained at the depth of 3-11 m. After clay is damped with water, it turns into plastic clay dough from which various products are formed. When dried, it becomes hard, and when heated up to 700 ^oC it loses crystal water and elasticity. When burnt at the temperature of 950 ^oC (fuel is sawdust), it experiences complex chemical and mineralogical changes in the material: some ingredients of clay start melting, and the liquid part “ties” separate grains and everything becomes hard, thick and smaller in volume. Additives are used to improve the structure: natural sand, crushed product breakage, sawdust or peat. Sand does not melt and just reduces shrinkage of products constituting the frame of the ceramic mass. Sawdust or peat burn out leaving air bubbles – micropores, which is why the structure of the ceramic mass is very close to that of wood. Wood – land (clay, sand) – water – air are natural sources giving naturalness to the product.

The construction of Kerapor ceramic units divides the material into numerous layers, pores, partitions and walls, and still air in hollow parts and pores is the best and healthiest heat retainer. A healthy house is the one whose walls accumulate heat, i.e. natural ventilation through the porous wall material is in place. One can start heating such houses in winter 2 weeks later, and stop heating them in spring 2 weeks earlier because ceramic units are an inert material.

The structure of ceramic units favorably influences human body, guarantees residents healthy environment, harmoniously enters their lives as if approximating buildings to the nature and does not emit any substances dangerous for human body.

Silicate building materials are made from mixture of sand, lime and water, hardening in hydrothermal circumstances in a pressure which is not less than 0,8 MPa. Silicate bricks and silicate blocks "Siliblokas" are one of the friendliest building materials to environment protection. It is one of few ecologically balanced materials. Silicate products are made from natural raw materials, which are hardened only in 200 °C temperature compressed water steam. Therefore amount of energy consumed for their production is not big, whereas that factor saves our environment. Heat-saving external walls from silicate bricks and silicate blocks "Siliblokas" already after two years save more primary energy than costs their production, including thermal insulation.

Autoclaved aerated concrete (AAC) is well known as an environmentally friendly construction material. "Poritas" is manufactured from common and abundant natural raw materials and the finished product is up to twice the volume of the raw materials used, making it extremely resource-efficient and environmentally friendly.The energy consumed in the production process is only a fraction compared to the production of other materials. The manufacturing process emits no pollutants and creates no by-products or toxic waste products.

AAC is a load-bearing block, which also provides thermal and sound insulation as well as fire protection, thereby eliminating the need for many different layers of materials. The workability of "Poritas" AAC helps to eliminate waste on the jobsite. The use of AAC can reduce indoor air pollutants. AAC is completely inert and does not emit toxic gases, even when exposed to fire.
