How to insulate air chambers that have fiber insulation inside

Low thickness polyurethane infusion

At the point when we thermally protect a structure we can find exteriors that have air chambers loaded up with past insulation in light of strands or glass fleece or mineral fleece, however which is lacking or has endured wear after some time. (Μoνωσεις)

For this situation , we can infuse open-cell low-thickness polyurethane, which packs these fleeces, working on the current insulation , lessening energy misfortunes or gains and contaminating emanations from that structure .

Infusing inflexible polyurethane froth on the façade is an extremely successful insulation arrangement. Polyurethane can be injected into a twofold layer façade, which can be made of block, concrete, concrete, covered mortar, metal or wood, for however long there is a space between the exterior and interior walls (air chamber) . The polyurethane is injected as liquid froth out of sight office of the façade, extending inside and framing an unbending open-cell froth with extraordinary insulating limit and extremely low thickness.

It is a cutting edge insulation framework involving polyurethane infusion in air chambers, with low-thickness polyurethane froth, with awesome thermal conductivity, which because of its frothing limit ensures excellent appropriation in air chambers.

Polyurethane injected inside

In the act of our calling, generally and typically, in Spain we can see that before the year 1979 the air chambers were vacant, without insulation . From around 1979 to 1995, they were loaded up with slender plates where insulation could be blown or injected. What's more, starting around 1995 we can find either air chambers loaded up with mineral or rock fleece or different materials, where there are still centimeters to fill , or completely filled air chambers, yet whose insulation can likewise be improved, for instance, with polyurethane froth, since even in these last option cases, the froth will pack the insulating material up to 80 percent , leaving opportunity to get better

What is polyurethane?

Polyurethane is the insulation gotten from the compound response of two items: polyol (got from sugar stick) and isocyanate, got from oil, which at a specific strain and temperature (38-50º) when consolidated produce polyurethane, an insulation plastic.

Polyurethane can't be viewed as normal, yet it is recyclable and deferential of the climate.

EcogreenHome utilizes the polyurethane infusion procedure just in façade air chambers and the item we use is from the maker Dow.

The characteristics of the infusion polyurethane froth are the accompanying:

Low thermal conductivity 0.038 w/m*k, like that of stone fleece

High thermal obstruction(Μoνωσεις ταρατσων)

Low fire conduct: Euroclass E

Low acoustic execution (half open cells)

Low unambiguous intensity: 650 joules

Low thermal slack (as long as 6 hours in thicknesses of 200 and 250 mm)

Hydrophilic: acceptable conduct against water or mugginess

The application method for this froth is infusion. This framework can be introduced in regions where there are holes with a base thickness of 20 mm for legitimate establishment.

It is great for the late spring heat.

Benefits of injected polyurethane:

Works on thermal way of behaving and solace, by wiping out external air invasions

Lessens airborne commotion from outside, on account of its open miniature cell structure

It ensures the all out filling of the air chamber , adjusts to any math and doesn't endure settlements over the long haul.

The glue idea of polyurethane makes it conceivable to unite the two sheets of the façade

Polyurethane keeps growths or microorganisms from multiplying and is a harmless material with extraordinary toughness and a helpful existence of over 50 years.

Concerning application, intelligently, it doesn't decrease the tenable space, since it is injected inside the air chamber and, accordingly, its execution makes no burden the client.

At Ecogreen Home we recall that all that adds to further developing the energy execution of homes is a significant wellspring of energy reserve funds. Also, this is vital in Spain, where the energy utilization of structures addresses 16% of the public aggregate. Check with Ecogreen Home and work on the insulation of your air chambers.
