Study of Residential House Construction Using Thermal Insulation Brick Compared to Brick Filled with Stone Wool

The procedure for constructing a residential house begins with the purchase of land and obtaining location information from the administrative unit where the plot is located. Based on the comparison carried out between POROTHERM 38 Profi thermal insulation brick and POROTHERM 38 W.i Plan brick filled with stone wool, I recommend to investors constructing a residential house the use of brick filled with stone wool, as it has better technical and physical properties, better composition of brick material and is of higher quality based on these characteristics and properties. Whilst brick filled with stone wool is more expensive, the execution time is the same.

Solution and Method

The procedure for constructing a residential house begins with the purchase of land and obtaining location information from the administrative unit where the plot is located. It is very important to obtain information about the implementing spatial act for the area where one wishes to build. After acquiring the right to build on the desired plot, it is necessary to find a designer with whom a design contract is concluded.

With the design contract, deadlines and payment for services are thus determined. The designer first prepares documentation for the investor to obtain a building permit, taking into account all legal provisions and restrictions that apply to the area of the desired construction. The building permit is obtained on the basis of an application for a building permit, to which we attach a project for obtaining a building permit, which contains all necessary consents.

The application for a building permit is also submitted to the administrative unit where the plot is located. The selected designer also prepares a project for execution. The project for obtaining a building permit and the project for execution are the fundamental documentation with which the investor approaches potential contractors and on the basis of which contractors prepare tender estimates.

The bulk of construction works are masonry works, whose fundamental building material is brick. There are many suppliers of different types of brick available on the market. For the diploma thesis, POROTHERM 38 Profi thermal insulation brick and POROTHERM 38 W.i Plan brick filled with stone wool were selected.

Both bricks are manufactured by Wienerberger. In the practical part of the diploma thesis, a comparison was made between POROTHERM 38 Profi thermal insulation brick and POROTHERM 38 W.i Plan brick filled with stone wool. Both bricks are manufactured by Wienerberger. Technical and mechanical characteristics, physical properties, fire resistance, material composition, brick quality as well as construction time and cost were compared.

Based on the assumptions, I can conclude that thermal insulation brick has inferior technical characteristics and physical properties compared to brick filled with stone wool, that thermal insulation brick has better mechanical characteristics and fire resistance than brick filled with stone wool. Thermal insulation brick has inferior material composition and is of lower quality than brick filled with stone wool. Construction with thermal insulation brick is equally fast as construction with brick filled with stone wool for a residential house, as the same principle of brick installation applies.

If we wanted the thermal conductivity to be equal, additional works would have to be carried out during construction with thermal insulation brick, which would require additional time, and that construction with thermal insulation brick is cheaper than construction with brick filled with stone wool for a residential house.

Results

Based on the comparison carried out between POROTHERM 38 Profi thermal insulation brick and POROTHERM 38 W.i Plan brick filled with stone wool, I recommend to investors constructing a residential house the use of brick filled with stone wool, as it has better technical and physical properties, better composition of brick material and is of higher quality based on these characteristics and properties. Whilst brick filled with stone wool is more expensive, the execution time is the same. In the event that we wish to achieve the same thermal conductivity, we must take into account additional work and material for insulation during construction with thermal insulation brick in order to obtain similar thermal conductivity as with brick filled with stone wool.

Therefore, if we wanted to achieve the same thermal conductivity during construction with POROTHERM 38 Profi thermal insulation brick as that of POROTHERM 38 W.i Plan brick filled with stone wool, we would have to additionally insulate the walls with insulation material during construction with thermal insulation brick, such as with facade polystyrene 8 cm thick. For this, we would additionally need approximately 5kg/m2 of adhesive and labour. The additional execution of insulation to achieve similar thermal conductivity as that of the mentioned brick filled with stone wool would cost approximately 8.72 EUR/m2 excluding VAT.

Based on the analysis and comparison of properties, characteristics, quality, material composition, construction time and prices of the selected bricks, I can assert that the set objective was achieved, as conclusions were reached with which advice can be given on the choice of brick in the construction of a residential house.
