Specialization: master in the construction of plasterboard structures, finishing work and laying flooring. Installation of door and window blocks, facade finishing, installation of electrics, plumbing and heating - I can give detailed advice on all types of work.

Most often, developers are interested in how the insulation is attached to the wall or ceiling, reading specialized resources on the Internet. But many sites offer information on the types of dowels for fastening or make reviews of adhesive compositions, and meanwhile fixing insulation elements is a complex process, and it should be considered as a whole, and not in separate fragments.

I will tell you how to attach different types of insulation to various structures: plinth, walls, ceiling and attic, these are the types of work that are most often performed.

Overview of work options

I will make a reservation right away - I will not talk about all possible methods of fastening, but will only touch on the simplest and most effective options that have proven their reliability among developers. Do not try to find smart technology, the simpler the workflow, the less likely it is for errors and defects.

Option number 1 - wall insulation

The question of how to fix the insulation to the wall is one of the most popular, since it is this type of work that is most often performed and for some reason causes great difficulties among developers. Let's figure out what you need to carry out work when attaching insulation for plastering:

Bending for fixing insulation	There are three product options: plastic products, elements with a metal nail and dowels with a metal nail and a thermal head. The length of the products should be 70 mm more than the thickness of the insulation in order to ensure high-quality fixation of the elements. The plastic version can be used with a length of up to 120 mm, if more, then the strength will not be enough, the nails in such products often break
Adhesive composition	There are many options for special adhesives for fixing thermal insulation on the market. There is no particular difference between them, the main thing is that they fit the type of thermal insulation material you have chosen. The composition should not be petrified, this is a sign that storage conditions have been violated, the quality of such mixtures is much lower
Mounting foam	It is needed when using foam and is used to fill the gaps that inevitably form when the material is attached. Usually it needs a little, but it all depends on how well the installation is done.
Work tool	It is impossible to prepare glue without a container and a drill with a mixing nozzle, but it must be applied with a special spatula or grater. In order to install umbrellas, you need to drill holes for them, so you must have a puncher with a drill of the desired diameter and length at hand.

I want to give you some tips on how to choose high-quality fasteners for insulation, or, as it is also called, a mushroom for thermal insulation:

• First of all, decide on the best option, I wrote above that purely plastic products can be taken with a length of up to 120 mm, if you need more options, then you definitely need to purchase dowels with a metal nail, as they are more durable. It is best to choose the option with a thermal head, in which the cap is closed with a special plastic plug, which prevents the formation of cold bridges and eliminates the appearance of corrosion spots on the surface;

Now let's deal with the workflow, first I will show the diagram, and below I will describe in detail each of its points, so you can quickly understand all the nuances:

• Next, the fastening of heat-insulating sheets begins, for this a solution is prepared, which is applied to the back of the insulation. As for the foam, it is enough to apply glue around the perimeter and in a couple of points in the middle. Mineral wool, due to its large weight, must be glued more thoroughly: the composition is applied to the entire surface with a notched trowel (tooth size 8-10 mm);

• If you have foam, then you can simply glue it with glue in cylinders. Moreover, you can glue both to concrete and to wood, this method is considered universal. In addition, the price of this material is low, which makes it the most attractive among all;

Conclusion

I hope that this kind of instruction will answer all your questions regarding the fastening of thermal insulation materials. The video in this article will talk about some important points in more detail, and if you have questions, then ask them in the comments below the review.
