Tips for insulating a brick house

Everyone knows that a house made of brick is very reliable and durable, and therefore, such a house is not at risk of various disasters. But brick has one drawback - it does not retain heat in the house well. To do this, you need to know clearly that walls of one layer 40 - 65 cm thick, built of brick, ceramic stones, and small expanded clay concrete blocks, make the thermal protection level 3 times less than necessary. How to be? The answer is clear - the walls need to be insulated. Namely, to insulate the walls of such a house from the inside. 


In order for everything to be correct, you first need to put waterproofing on the wall - a vapour barrier film, for example, Ondurin R 70. On top of such insulation, you need to place insulation and then cover it with a vapour barrier. But it would be better to insulate the brick wall from the outside. After all, by doing so, you will not reduce your living space, although this is not the only reason. The point is also that the constantly released moisture from the air gets into the walls, turning from heat to cold, in which case it will freeze in the winter, not in the wall of the house, i.e. its dew point will not be inside the wall. Therefore, the wall will not collapse.


Insulation materials


In order to insulate a wall, there are various insulation materials—the most common among them: expanded polystyrene, polystyrene foam, and mineral wool. Moreover, insulation will not prevent you from cladding your house with wood, ceramic tiles, or siding since it can be placed between the wall and the cladding.


Mineral wool does not burn, and this is its advantage over expanded polystyrene, which, in turn, is much more affordable. Polystyrene foam is even cheaper and holds heat a little worse, but not so much that you forget about it.


How to insulate your brick house is up to you to decide; everything will depend on how much you expect. Many owners of houses and cottages think that if they insulate their houses with polystyrene foam, then in the summer, it will be a little hot there. This idea needs to be corrected. Any insulation has such properties that it keeps warm in winter but cool in summer since it increases the width of the walls. Moreover, new insulation materials tend to remove moisture and steam from the house without letting it in without absorbing it.


It has long been known that we spend approximately 40% of our energy on heating and cooling our homes. We can avoid these unnecessary costs! The essence of the insulation is that due to its qualities, insulation 10 cm thick can increase the thickness of the wall to a conventional meter in terms of brick. As a result, you can save a lot of money! 


Insulation of a brick building from the outside


Much depends on the correct installation of insulation. For example, let's take the installation of insulation under siding. To begin with, you need to lath the entire surface of the wall of the house using wooden slats. They must be secured at a distance of approximately 30 cm from each other. The thickness of the slats should be equal to the thickness of the insulation. A mineral wool slab should be placed between the slats. In order for the insulation, which has pores, not to absorb moisture due to rain or take it from the ground, it is necessary to stretch the film so that it allows moisture to pass only in the direction away from the room. A film should be placed on top of the mineral wool slab, which will protect the house from moisture and wind. The film and insulation are closed with slats using a stapler. You need to make a sheathing on top with slats and then attach the siding to it.


If you will insulate a brick house with polystyrene foam, then it is safer to take TEPLEX. It is much better than polystyrene foam because it is non-flammable, non-toxic, and has good sound insulation. However, since polystyrene foam is much cheaper, you can use it. It is also a good insulator despite its shortcomings. It is better to spend more money on insulating the house with polystyrene foam. There are no problems with its installation.

The entire area of ?? the insulation is coated sheet by sheet with construction adhesive. After this, they are applied to the wall, tapping with a rubber hammer so that the glue is distributed over the entire surface. Immediately, before the glue has set, the sheets are drilled in the centre and the corners with a puncher, choppers are inserted into the holes, and specially designed umbrellas are driven into them. They should be driven as deep as possible. The next day, a plastic mesh is stretched over the foam and covered with a layer of cement mixture. If there is siding on top of the foam, then wooden blocks need to be attached between them.


Which Material to choose?


According to insulation installers Central Coast,it is better to take insulation on a basalt basis: Izolight 50, Light-Butts, Izolight L-35, ROCKWOOL, TECHNOLIGHT Extra, PAROC eXtra. It is also possible on a fibreglass base: ISOVER KL-37, ISOVER KL-34, ISOVER KT-37-TWIN. It is better to put vinyl siding on top of the insulation: Mitten, Alta Profile, Gentek, Docke, Tecos. To secure the siding, you can take galvanized screws 4.5 x 30.0 mm.
