  • About Brick - Why Use Insulated Bricks ?
- Dry unit bulk density is less than < 700, and has high resistance.
- Provides acoustic insulation as well as thermal insulation.
- No grout is used for vertical coupling, only horizontal surfaces are grouted because of its tongue-and-groove system, it is economical and easy to apply.
- They can be used with any type of plasters, it does not cause fractures.
- Our prices include delivery to construction site. You don't need to pay for unloading.

CURTAIN SPACES OF 6 CM2 OR LESS

One of the biggest factors effecting thermal conductivity calculation in accordance with TS EN 771-1 is bricks with curtain space (gaps between the brick’s wall thickness) surface area less than 6cm2.
In order to prevent thermal convection and to obtain a stable air in the area, it should be limited to this area. Surface areas of the curtain spaces should be bigger than the stated value both for AB and W class bricks. Maximum dimension used for curtains is 1.5 x 4 cm or less. Curtain space widths more than 15 mm are considered to be non-standard. Thermal convection starts after 15 mm. And this of course will Raise conductivity calculation value. On the other hand, in accordance with the schema displaying thermal convection over the brick wall thickness around curtain spaces, the transition from the lateral surface of the brick to curtain shall be as shown above.

EXTENSION OF THERMAL PATHS BY CHECKER BRICK CURTAINS

Extension of thermal paths will cause thermal conductivity calculation value drop down since the heat transits through out the brick’s wall thickness conducts to the other end on this type of bricks. The heat is forced to take a path twice as long as normal brick thickness in this type of bricks. For example, W class insulated brick used for a 24 cm wall has over 48 cm of thermal path.
In addition, the thermal energy breaking up at each curtain coincides with the thermal energy coming from the other curtain on the following curtain, connecting two heat paths, slowing the transition down.

PRESSURE RESISTANCE AVERAGE 87 kgf'cm2

There is an average of 87 kgf'cm2 difference between this type of bricks that is required to resist minimum of 40 Kg pressure value per square meter per TS EN 771-1 and the ones presented to the market. As you can see, this value is 2 times more than the required value. This is the biggest proof for endurance of this brick.

VERTICAL BRICKS BULK DENSITY AVERGAE 650 Kg'm3

Average bulk density for this type of insulated bricks is 650 Kg/m3 in accordance with TS EN 771-1.


THERMAL INSULATION BY INSULATED BRICKS

1. No grouts used for vertical connections: Only horizontal surfaces are grouted. Vertical thermal bridges are eliminated since the vertical connections are not grouted.

2. Space surfaces on brick are less than 6 cm2. 6 cm2 is the optimum value for stable air. The space areas on insulated bricks are designed accordingly.

3. Thermal paths are extend by checker gaps:
The gap system on insulated brick width is designed as checker brick system. Checker gap system extends the thermal paths minimizing the thermal bridges.

4. Porous light structure:
The porous structure of Insulated Bricks create small air gaps providing thermal insulation and light weight bricks.

5. Bricks store the day light thermal energy by the heat storage feature of clay's natural structure, and releases at night, after the heaters are switched off. Thus, a comfortable and climatic environments are obtained.


HOW DOES THERMAL INSULATION WORK

1) No grouts used for vertical connections
2) Thermal paths are extended by checker curtains
3) Curtain spaces of 6 cm2 or less
4) Porous structure
5) THERMAL ENERGY STORAGE feature of natural clay

The methods for dropping down the thermal conductivity calculation values required for thermal insulation are outlined above. These items shall be evaluated in detail. The porous structure was not set as requirement, it is an optional feature.



Thermal Conductivity
Insulated Brick checker air curtains surfaces are not more than 6 cm2. Thus, thermal transition by air is prevented.





CLASSIFICATION

TS EN 771-1 standard has been updated more especially in this period due to increased importance of thermal insulation and issuance of new thermal regulation TS 825.
These type of bricks are manufactured under 3 main categories of Normal, Grout Pocket and Tongue-and-Groove System. These types are also classified as AB and W.
Class W bricks have lower thermal conductivity calculation values. This detail is provided in TS 825 Thermal Insulation Regulation.
