Rock wool thermal insulation in Vicenza

Work begins with the installation of the baseboard, which is laid at the base of the insulation system to prevent moisture from rising, and continues with the installation of the rockwool panels. The baseboard is specifically designed to form the base of the insulation system. It is usually made of extruded polystyrene or adittivated polystyrene, materials that have been tested for this use.

As you can see from the photos, we also take care of everything relating to the assembly and dismantling of scaffolding in accordance with the law, a service that we provide at the customer's discretion and according to his request.

We would like to point out and let you know that in the event that the external walls need to be cleaned of smog and dust deposited over the years, on the first day of work the application team carries out a wash with a high-pressure cleaner. As well as cleaning the surfaces, the water wash allows us to assess the condition of the substrate and any deterioration of the plaster, so we can understand whether there are any detachments or problems such as cracks, crazing that need to be treated before the coat is applied.

We have therefore understood that, in order to be suitable for installation, the substrate must be as coplanar as possible, without detachments and flaking plaster that could compromise the coating system.

This is a very important phase because it is necessary to decide whether to start immediately with the application of the coat or whether it is first necessary to treat the walls with primers and fixatives.

In this first phase we had to take into account that the house had many cornices with height differences of up to 2/3 cm! In order to give the finished work the visual impact of a surface that is as linear as possible, we worked with panels of different thicknesses in order to make all the walls uniform.

The gluing of the rockwool panels with the glue spreader must follow the system engineer's standards, and in the corners all the panels must be staggered so that they overlap and fit together, thus creating a single body. Please note that the panels are cut to size on site, only in this way can we be sure that they follow the course of the external walls.

Once the gluing phase is over, the panel must be doweled to the walls according to the specifications of the roofer, because in order to guarantee an adequate laying, besides the glue, a mechanical fixing must be used.

A small focus is on high-density supports, which are essential in the construction of a thermal insulation.

High-density plates are used for all external elements such as lamps, lights, spotlights and alarms. They are made of very high-density polystyrene, which is very resistant but does not allow excessive loads. For this reason, dried and treated laminated beams are inserted during the panel installation phase to create the right support for the heat pumps.

In these cases the beam is fixed to the wall to create continuity between the wood and the heat pump brackets, which are anchored to the support.

This system is essential with heavy weights that cannot be handled with high density plates.

With these photos we enter the shaving phase of the thermal insulation, we understand specifically what happens.

During the smoothing process a mesh is inserted to reinforce the layer of plaster that will then be executed over the rock wool. 

Once the dowelling of all the panels has been completed, the first skimming is carried out and the reinforcement mesh is inserted and embedded. After the reinforcement mesh, two more coats of smoothing are applied to make the entire surface linear and homogeneous.

Once you have checked the drying of the shaving layer with a hygrometer, you can proceed with the final finish!

The customers have chosen a colour from our colour chart in shades of blue. In this case the type of paint is a pure siloxane plaster, which has the characteristic of being very breathable and of remaining cleaner than acrylic colours. In fact, all our finishes in the coating systems have anti-mould and anti-algae additives, which allows the colour not to deteriorate over time.

In the last phase we proceed with the application of a fixative primer and then apply a thick finish that is applied with a professional spatula.
