Disadvantages of blocks

Narrow bars cannot, like massive ones, be dried as part of a log house. This is one of the reasons for using only dry and high-quality material for construction. This technology is very demanding on the accuracy of cutting locking joints. Thin material does not forgive negligence and additional gaps. Therefore, all locks are cut on special equipment. Prepared parts are delivered to the construction site, which do not need to be finished and adjusted locally. They are simply assembled in a predetermined order.

Externally, double hollow walls are indistinguishable from solid wood walls. When cut with end release beyond the connection, a double-ended pattern is formed at the corners and end cuts.

We will now evaluate the thermal efficiency of a wall constructed using double-beam technology, with a joist thickness of 60 mm and a layer between them of 150 mm filled with mineral wool with a thermal conductivity of 0.043 W / (m ∙ K).

Which brick is better thermal insulation

skip to contentmain ” Heaters Heat retention inside the room depends largely on the parameters of thermal insulation of the structure itself and the finishing materials used. Reliably insulating a house means reducing heating costs. Today, the construction industry offers many varieties of insulating materials, which vary in their characteristics and costs. One of the most optimal options is liquid thermal insulation Korund, which is distinguished by its durability and excellent thermal insulation properties. Let us consider in more detail the features of the composition, selection criteria and application technique.Characteristics of ceramic thermal paint.

Novablock advantages and disadvantages

The insulation of the building envelope not only improves its energy efficiency, but also guarantees its healthiness and the thermal comfort of the users. For this reason, current legislation specifies the minimum insulation required to ensure thermal comfort and indoor air quality.

All materials used in construction have a greater or lesser resistance to thermal transmittance. In some cases, such as metals, this resistance is very low. Other more traditional materials such as wood or brick have a medium resistance; and, finally, there is a group of insulating materials that offer high resistance and, therefore, excellent thermal behavior.

When we talk about insulation in building facades, we are referring to the insulation that is normally carried out in double-leaf walls with an air chamber. These walls are those that are formed by two parallel rows of bricks or blocks, leaving a separation between them called air chamber.

Advantages and disadvantages of lightweight block

When a sound wave with an energy (Ei) strikes the surface of a material, a portion of its energy will be specularly reflected (Er), another portion of energy will be ‘absorbed’ by the material (Ea) and finally another portion of the energy will be transmitted through the material (Et).

As we observe in the following balance, when we increase the absorbing capacity (pj we double it), we only reduce the amount of energy reflected, the amount of energy transmitted remaining practically unchanged.

For both families this is a very generic description; in practice, within each of them, there are different subclasses, and in some of them materials are even used, with very specific characteristics, which basically belong to the opposite family.
