1. Thermal insulation materials
Many types of thermal insulation, some of which have been abandoned throughout
history.
Aluminum.
Thermal losses can be by esatado change (evaporation), in contact (or convection) or
by radiation (which increases with the fourth power of the temperature difference),
achieving the aluminum mirror, and thus reduce by 97% the thermal radiation losses
(both cool protecting from the sun, and before the cold, to retain heat inside), this
property being independent of the thickness of the aluminum layer. Besides aluminum
offers another advantage, being totally watertight / impermeable and prevent the
passage of water and air, thereby blocking convective losses.
Cork.
Is the material used since ancient times to isolate more. Typically used as
agglomerates, forming panels. Typically, these panels are made from crushed and
boiled cork at high temperatures. In general, it is not necessary to add any binder to
compact panels.
Its water content is less than 8%, and is composed by 45% by suberin. These two
conditions mean that a product is imputrescible, which do not try to protect from fungi
or microorganisms, unlike wood.
Another advantage over other insulating materials is that presents high thermal inertia.
This feature makes it an ideal material for thermal insulation systems abroad SATE
53% of the world's cork is made in Portugal, and 32% in Spain.

Rockwool.
Stone wool is a thermal insulation, fireproof, rot. This material is different from other
insulation that is fire resistant material, with a melting point in excess of 1,200 ° C.
The main applications are insulation cover both inclined and flat (European cover
conventional, self-protected with waterproof sheet), ventilated facades, facades
monolayer, the interior walls, interior partitions, floors and acoustic insulation slabs.
When it has a roof tile with grooved, using a felt or other uncoated kraft paper with a
face, which helps position. It is also used for passive protection of structures such as
facilities and penetrations.
Stone wool is sold or semi-rigid panels, mats, blankets and shells armed. It is also an
excellent material for sound insulation in lightweight construction, flooring, ceiling and
wall finishes.

Blanket
Is rock wool fibers intertwined. It is suitable for isolating horizontal constructional
elements, provided in the upper position. Clamping vertically or staples need to
prevent clumping ends in the bottom of the element and in the bottom of a

7. horizontal hook. They usually come under Kraft paper, tar paper or light metal mesh.
Rigid panels
These agglomerated panels with any epoxy resin, which gives a certain rigidity to the
insulator. Serves for vertical and horizontal construction elements for the bottom, a
change of conductivity having a slightly lower coefficient to the blanket.
Coquillas
Are preformed tubes with various diameters and thicknesses. Like all good thermal
insulator, the section should be chosen so that it is perfectly adjusted to the outer
surface of the driving is isolated. Like any mineral wool is incombustible. Stone wool
can withstand temperatures up to 1,000 [° C].
Glass wool.
When you have a tile roof with a tongue-and I want to isolate with glass wool product
must be used for that purpose, a glass wool panels with greater density, hydrophobic
and hygroscopic. When you have a tin roof, the product line to be used is the cladding
with aluminum foil on one side reinforced to act as mechanical strength, such as vapor
barrier and reflective material. As in the previous case is sold in the form of blanket
pellets and shells panels pipe insulation.
Coefficient of glass wool thermal conductivity: 0.032 W / (m · K) to 0.044 W / (m · K)
Lana.
It is natural and organic version of isolates woolly. Unlike rock wool or glass wool,
sheep wool is obtained naturally and does not need a high temperature baking. It is
very tough and a potent regulator of moisture, which contributes greatly to the comfort
inside buildings. Construction hardly used in comparison with glass wool or rock.
As in previous cases sold as a blanket, and flakes of Chipboard.

Glass expanded.
Addition of insulation is a very effective vapor barrier, which is not usually normal for
heat insulation and makes it very suitable for insulating thermal bridges in construction,
as pillars in front walls. Is formed by glass, usually recycled and treat smooth color,
since no matter what color the product, which is a foam hot gas leaving enclosed cells,
which act as an insulator. Its stiffness makes it more suitable than other insulating
plaster to cover it. It is rarely used in the construction. Glass is also known as Cellular
and still currently manufactures, 2013, in Spain under the latter name.
Fragment of expanded polystyrene.
The polystyrene foam material is an insulating petroleum and natural gas, of which the
polymer is obtained as styrene plastic granules. To build a block is incorporated in a
metal container a certain amount of material is related to the same final density and
water vapor is injected to expand the granules to form the block. This is cut into slabs
of the desired thickness for marketing through a heated metal wire.
Due to its flammability was incorporated flame retardants, and is called flame.
It has a good thermal performance in densities ranging from 12 kg / m³ to 30 kg / m³
Has a conductivity coefficient of 0.034 to 0.045 W / (m · K) which depends on the
density (generally lower density to higher conductivity coefficient)
It is easily attacked by the ultraviolet radiation and therefore it should be protected
from sunlight
It has a high resistance to water absorption

9. No way that the burning flame and sublimates.
Foam cellulosic
The foam material, cellulose has an acceptable thermal insulating power and is a good
acoustic absorber. It is ideal for applying to the bottom of sheds being a fireproof
material completely white and its speed to be placed. It melts at temperatures above
45 ° C. Is little used in construction.
Thermal conductivity: 0.065 to 0.056 W / (m · K)
Polyethylene foam
Chemical structure of polyethylene, sometimes shown only as (CH2-CH2) n.
The polyethylene foam was characterized by economic, waterproof and easy to place.
With respect to its thermal performance can be said to be of average character. Its
completion is white or aluminum.
Thermal conductivity: 0.036 to 0.046 W / (m · K)
Polyethylene foam Film
Similarly, the foam of polyethylene, is used as thermal plastic bubble simply covered
with aluminum foil. The advantages versus other insulators are very small thickness
(3-5 mm), easy installation, very low cost, it is also non-flammable and recyclable. This
film is little used in construction, and more usually in air conditioners.
Polyurethane foam.
Displays polyurethane foam high density.
The polyurethane foam is known to be a very good insulation performance. It has
many applications such as thermal insulation in construction and in industrial sectors.
Highlights throughout the cold chain by high efficiency energérica
Thermal conductivity: 0.023 W / (m · K)

10. Elastomeric foam
Is an insulator with excellent performance in low and medium temperature and easy to
install, minimizing the costs of labor. It has in its structure a vapor barrier and
completely fireproof behavior.
Coef. Conductivity: 0,030 kcal / h · m · ° C
Optimum temperature: -40 to 115 ° C
It is easily attacked by the ultraviolet radiation and therefore it should be protected
from sunlight.
Aerogel.
As thermal insulation, airgel blankets occurs in flexible (range: -40 ° C to 650 ° C or -
270 ° C to 90 ° C). Only comes in 5mm and 10mm thicknesses. It has great
mechanical properties for the performance it delivers, is hydrophobic (repels moisture),
is permeable (lets through air / vapor), prevents corrosion under insulation is fireproof
(not burn) and is highly resistant to harsh treatment (stomping, hitting, etc.). Installation
is intuitive and simple, the material can be cut with scissors or cutters, reducing the
time and costs of excessive labor.
