How to insufflate

What's this?

Insufflation is a modern and technological thermal insulation system (and in some cases acoustic) consisting of injections of insulating materials in the building cavity.

How does it work?

1. INSPECTION - The first thing to do is to carry out an inspection to evaluate the feasibility of the operation. A cavity of at least 5 cm is necessary without the presence of obstructions inside.

2. EVALUATION OF MATERIALS - there are various materials that can be "insufflated" such as:

• fiberglass;

• Rock wool;

• cellulose fiber;

• expanded polystyrene (EPS);

• cork granules.

3. TYPE OF INTERVENTION -

• External insufflation: the external wall of the house must be drilled in several points at a distance of one meter from each other. This operation necessarily requires the involvement of all condominiums and the request for permits, authorizations and external scaffolding. It therefore appears to be a complex intervention both in terms of costs and timing.

• Internal blowing: intervention that involves drilling the internal wall of the house in several points at a distance of one meter from each other and about 50 cm from floors and ceilings. The selected product is then introduced with a specific machine and the holes are closed at the end. This intervention requires rapid times and an excellent quality / price ratio.

When is it requested?

Insufflation is carried out to improve the thermal appearance of a home (and in some cases acoustic) and therefore avoid heat loss. If this intervention is combined with the replacement of the windows, the economic savings become very interesting.

N.B: the essential step in calculating energy savings is the inspection phase. The presence of some structural elements such as pillars and pipes could cause thermal bridges.

Costs?

An insufflation operation can cost an average of € 27.00 per square meter.

However, the variables that affect processing costs are different.

Let's see which specifically:

• Insufflation technology used;

• Internal or external blowing (see above described);

• Type of material to be inserted in the interspace;

• Thickness of the cavity (the wider the thickness, the more product it will be necessary to fill it);

• Existing tax deductions.

Conclusion

ATTENTION: being this type of intervention very delicate, the advice is to contact a highly specialized company that can help you.
