At Torregra we carry out blown thermal insulation in communities, hotels, schools, residences and other large buildings, adapting each intervention to the use and characteristics of the property.

Blown-in thermal insulation
In a large building, the challenge is not only technical, it is also logistical: access, users, schedules and work areas must be coordinated.
Blown-in insulation can be a particularly good fit when suitable air chambers exist, because it allows intervention through spot perforations and subsequent sealing, without dismantling the enclosure.
The system and the necessary access means are defined after the technical study.
We plan to minimize disruption and maintain activity when the building allows it.
We plan by facades, floors or zones according to use.
Inspection of cameras and access points before budgeting.
Base in Viladecans and own mobile team.

Each type of building has its own priorities: schedule, safety, user comfort, accessibility, or continuity of activity. We adapt the intervention plan and the selection of insulation to the specific characteristics of each project.
Aislamiento térmico insuflado
En Torregra mejoramos el aislamiento de viviendas y edificios mediante aislamiento insuflado en paredes, fachadas, techos y cubiertas.
Antes de cada instalación analizamos la cámara de aire con cámara endoscópica para saber qué solución y qué material se adaptan mejor al inmueble.
We inspect facades, roofs, and chambers to check if blown-in insulation is viable.
We prepared the technical proposal and the budget so that the community could evaluate them at the meeting.
The owners' association approves the action and the schedule is set.
We carry out the work according to the agreed schedule and the accessibility of the building.
If the community does not approve the joint action, each owner can assess the insulation of their home from the inside.
More information about this system can be found on our blown-in thermal insulation page.
Blown-in thermal insulation
METHODOLOGY
We inspected cameras, facades and access points to confirm the viability of the system.
Phased schedule adapted to the building's activity.
We made the necessary perforations and blew in the insulation according to the configuration of the chamber.
We sealed the access points and reviewed the intervention, taking care to respect the existing finish.
Our materials
In buildings for collective use, the choice of insulation must consider the thermal and acoustic performance, the conditions of the chamber, the use of the building and the declared performance of each product, including its behavior in the face of fire when relevant.
| Material | Strength | Selection criteria |
|---|---|---|
| Rock wool | Good thermal and acoustic performance; high fire resistance products are available | When the project prioritizes thermal, acoustic, and fire resistance performance depending on the product |
| Mineral wool | Versatile solution for different chamber configurations | Depending on thickness, chamber geometry, and required performance |
| Cellulose | Recycled paper fiber with thermal properties depending on the product | Projects where its performance and characteristics are compatible with the camera and use |
| Cork | Natural and renewable material | Projects that prioritize natural materials, provided the solution is technically suitable |
In many cases, yes. Blown-in insulation is installed through targeted perforations and can be planned so that occupants can remain in the building, provided that access, safety, and work organization allow it.
It depends on the surface area, the configuration of the cameras, access to the facades, and the phased planning. The technical study allows for the definition of a realistic schedule before work begins.
It will be presented at the homeowners' association meeting. We will prepare the technical report and the budget so that the community can make an informed decision.
There is no single best material for all buildings. The choice depends on the camera, the lenses, the building's use, and each product's certified performance, including its fire resistance where applicable.
It may be possible to act on specific facades, orientations or areas, but first it is necessary to assess the continuity of the insulation and how a partial intervention will affect the overall behavior of the building.
The price depends on the surface area, the thickness of the air gap, the material, and access to the facade. That's why we conduct a technical study before providing a quote.
We study the facades and the roof to check if there are suitable cavities for blown-in insulation and to define the feasible scope of the intervention before preparing the budget.
