Thermal and acoustic insulation

Thermal insulation is gaining importance every day, due to the rising price of energy resources (electricity, gas ...)

Good insulation can avoid wasting heat in a building up to 30% of energy, which results in reduced electricity bills and CO2 emissions harmful to the environment, so the institutions require new construction to meet energy efficiency standards.

The isolation of a home depends on several factors, mainly on the quality of material and technique that are built the walls, ceilings and floors, but are especially important in walls, windows and doors to be aluminum com RPT , PVC, mixed carpentry, always accompanied by a low-e double glazing to keep the temperature of our house.

Regarding the sound insulation, the use of double or triple glazing greatly helps achieve this, although there are special glasses, such as Silence Climalit, consisting of two panes joined by a special plastic film, assembled between the two leaves, depending on the glass thickness, significantly reduces the perception of sound.

In ALUMÁLAGA we have a wide range of possibilities to solve each of these needs.

GLASS HEAT (low emission)

The double glazing, enhanced thermal insulation, such as a Climalit Plus Planitherms insulates your home with both cold and heat, is made up of two glasses, one coated with a thin transparent layer of silver based. is achieved with Planitherms retain heat in your home during the winter and summer heat prevents from.

Reinforces the layer of low thermal emissivity, it is always placed inside the double glazing, the space between the two panes, which is the chamber can be filled with air or argon gas, it is important to the maximum size camera, but it will be limited by the space of leaves of the window which is to be glazed, as it improves the thermal insulation.

There is another double glazing which is more efficient, as the Planistar One, which is formed by two windows, one of which is coated by a thin transparent layer of noble metal oxides, which achieves during the cold periods retain heat in the heating inside your home, in the hottest periods prevents excessive heat from the sun into your home, why not canceling the entry of natural light.


In addition to the factors involved to windows and walls, there are other things you should consider, such as blinds or compact monoblock, which must be double-walled PVC, there is a case of PVC, double wall, which has unique in that the cover design allows us to place a reinforcement of polystyrene, to thereby achieve a higher thermal and acoustic insulation, in addition, the blinds must be designed and properly sealed to the window.


The material from which the building is the enclosure also influences the ability of insulation, PVC and aluminum MTN, have both the same tightness in relation to water and wind, although it is true that with regard to thermal insulation and acoustic, PVC has better performance, since being a plastic material is not temperature transmitter or sound, though, thanks to the thermal break, the difference is minimal.

Another type of material, which is the great unknown, carpentry joint, which is a profile on the outside is aluminum and the interior is solid wood (pine, sapele, oak) these two materials are joined by a polyamide fiberglass, that apart from these two materials join and separate permit their expansion, also makes thermal break, combined with the timber, offers a very good performance, both thermal and acoustic, and a large warmth and beauty, a quality that only wood can give.


This term as used in the manufacture of windows, refers to the transmission of the temperature between two materials.

In aluminum windows thermal breakage, these rods are polyamide reinforced glass fiber, joining the aluminum itself that forms the window separating the outer face of the inner thus avoiding the transmittance of temperature between the inside and exterior of the aluminum window, preventing condensation and reduce sound vibrations through the window, this achieves a better capability of both thermal and acoustic insulation, polyamide also gives us the possibility of two-color profiles.


The insulating ability of a window depends on the isolation level profile and the glass. Is measured by the value "U" which measures the heat exchange occurring between outside and inside of the window value U value (W/m2K)

The lower the value U section and the greater the capacity glass insulation has the window.
