The blown-in insulation system offers clear advantages that make it the most recurrent option in homes.
If your home does not offer suﬃcient thermal comfort, it is time to improve your family’s quality of life and save on electricity bills, even more so now that its price continues to rise.
Insuﬄation is the thermal insulation technique with the least complications for the client, cheaper and faster (even in less than 24 hours), with which savings in air conditioning of more than 60% can be achieved.
In addition, you can intervene from the inside without having to move and even from the outside. This solution is also ideal because it does not imply the loss of useful space by taking advantage of the existing empty space inside the walls.
What does the work consist of?
Once conﬁrmed by our specialists that the enclosure walls have suitable cavities for insuﬄation by means of an endoscope inspection, proceed as follows:
Can blown ceilings be insulated?
As long as it is possible to access the hole to be ﬁlled with insulation, this technique is equally interesting for roofs.
Speciﬁcally, it can be insulated with this technique, if it is a sloping roof with an air chamber, by insuﬄation, or when it is possible to access the cavities between pigeonhole partitions that support the tiles, by blowing. Contact us to conﬁrm if it is feasible in your case.
Inﬂated: what are the beneﬁts?
Insuﬄation is a fast and economical insulation technique that does not change the appearance of the façade , nor does it require scaffolding if it is carried out from the inside, although it can also be carried out from the outside of the home or building.
Execution times are very short. In fact, in many cases, it is possible to get the job done in a single day, beneﬁting from immediate energy savings.
Thanks to the intervention, it is possible to access deductions from 55% – 65%: the investment is amortized in a few years.
Insuﬄation for thermal insulation of walls and ceilings: an operation that requires professionalism and experience
The concept of cavity insuﬄation is simple, but requires a reﬁned technique. The existence of installations (wiring, ducts, etc.) and the technical speciﬁcations of the wall must be previously checked, so a correct endoscopic inspection by an approved installer is essential.
The wall must be observed both internally and externally.
In addition, it is necessary to check, through minimally invasive interventions, the thickness of the ventilated cavity. Make sure there are no obstacles such as debris, the position of columns, frames, roller shutter boxes or gaps. Analyze the ventilation, the interruptions of the facing by other elements and proceed to the correct preparation of the support for said purposes.
If the requirements for intervention are met, a series of steps are performed:
- Holes for the insertion of the insulating material, at a horizontal and vertical distance not exceeding 1.5 m. The drilling scheme of each wall must be planned independently and around each window and door.
- Next, the insulating material is inserted with a speciﬁc blowing machine and adjusting its parameters to ensure the correct installation density.
- As proof, a special box is used, manufactured in accordance with the EN 14064-2 standard, through which it can be veriﬁed that the installation parameters are correct.
Blown materials improve interior acoustics, reducing noise throughout the home or workplace, enhancing the sounds you want to hear and quieting the ones you don’t want from outside.
Among the blown materials, rock wool stands out as the most eﬃcient acoustic insulation in the sector.
Protection against the ﬁre
The insulation provides protection against ﬁre. Thanks to its ﬁbers resistant to high temperatures, it will limit the effects of the ﬁre of a ﬁre:
- Protects combustible constructions or those susceptible to the effects of ﬁre
- Increases the ﬁre resistance of structural elements
- Does not feed or spread ﬁre
Our insulations have been used as crucial, reliable and proven components, providing ﬁre protection in structural elements and technical equipment.
Materials we blow
Rock wool for blowing or injection. Material derived from volcanic stone in the form of bulk rock wool nodules, therefore inﬂatable between walls and partitions. This product has unique properties, such as being rot-proof, resistant to humid environments and resistant to M0 or A1 ﬁre.
Installation of RockWool® Stone Wool in your home
- It depends on the size of the house. As a guideline, the application is done in a single day in the case of ﬂats and 1 to 2 days in the case of single-family homes.
- Only several 25mm diameter perforations will be made from the outside of the façade, or 40mm – 80mm perforations if false ceilings or plaster partitions have to be inﬂated from the inside.
Properties of RockWool®Stone Wool
- Rock wool is ﬁreproof and non-combustible (A1)
- The blown rock wool we use is water-repellent
- Rock wool is porous, therefore it acts as an acoustic insulator
RockWool® Rockwool Applications
- Insuﬄation of false ceilings in arcades with the presence of water pipes
- Insuﬄation in non-watertight roofs with leaks
- Insuﬄation close to chimneys, boilers, hot tubes
- Insuﬄation of small tubes connected between ﬂoors
- Inﬂated in ventilation chambers (except basements)
- Insuﬄation of false ceilings in places of public concurrence
- Insuﬄation of facades of high-rise buildings
Isofloc® is a material made from shredded newspaper, to which additives have been added to give it ﬁre retardant properties, against fungi, rodents and insects, obtaining a material with surprising thermo-acoustic insulating characteristics, totally ecological based on a recycled product.
Properties of Isoﬂoc® Cellulose
- Isoﬂoc cellulose has ﬁre retardant properties thanks to the additives it contains. When a ﬂame of ﬁre approaches the cellulose material, the cellulose does not burn but instead blackens creating a black protective layer, similar to an oxidation process, protecting the cellulose under said layer from the ﬁre.
- It is inﬂated simply by drilling or projecting it, so scaffolding or major façade renovation work is not necessary to reinforce its insulation.
- It is an excellent acoustic insulation given its extreme porosity.
- It is distributed homogeneously in all the gaps, avoiding joints and areas that remain uninsulated, thus avoiding interstitial dampness and thermal bridges.
Isoﬂoc® Cellulose Applications
- Insuﬄation in interior partitions and cladding
- Insulation of unused roofs by projecting it dry between pigeonhole partitions that support a roof, plasterboard partitions, blowing it into hollow spaces in roofs, etc…
- Drywall or plasterboard insulation
- Insulation of wooden roofs or uninsulated roofs
- General cavity insulation
- Insulation of dormers and attics
Expanded polystyrene (EPS), a novelty in the form of lentils, has excellent insulating properties for chambers and insulation between exterior façade walls and interior tile.
The lentils are blown under pressure in the chambers and allow a homogeneous distribution of the insulation, avoiding the presence of thermal bridges. The lentils are impregnated with graphite, in this way the heat waves are reﬂected, before penetrating the insulating material, with an excellent result in thermal insulation.
Installation of Neopor® Polystyrene
- By dry blowing
- By opening 25 mm perforations on the outside or inside
- The pressure causes the material to be completely distributed in the chamber in a homogeneous
Polystyrene Neopor® Applications
- To isolate thin cavities (ventilation chambers from 1.5 cm thick)
- Cavities with possible presence of interstitial dampness (facades that do not perspire)
- To isolate very irregular cavities
- To isolate ﬁssured facades
- To insulate in mountainous areas with extreme cold
- To isolate areas that require a waterproof insulation
- To isolate chambers from facades, go outside, when they are made of exposed brick.
