This is an article where we are going to try to understand graphic and of course quite simple the world of insulating materials in rehabilitation, providing us with knowledge for the works or any construction from the perspective of thermal insulation (We leave aside the acoustic and electrical insulators ) that the house or building will need.
To understand it, we are going to base ourselves on two guides that undoubtedly are exceptional and that every architecture professional You should have in your repertoire of notes. Two documents, which Together they will provide us with valuable information on what insulating material do we need to put in a housing in the face of a roof rehabilitation, facade or vertical or horizontal partition.
To limit energy consumption we have to start from the thermal envelope:
Remembering that to reduce energy demand in a existing building, we are affected by five factors:
So determine the types of materials insulators that we have on the market, understand their properties or when we can put them in a house, it is a key point on energy saving.
Content menu:
Although it is evident that properties before the insulating materials evolve day by day (We can see a innovative materials article here) yes there is a «standard catalog» and that everyone should know given its easy access and usefulness for rehabilitation projects energy.
Three factors are necessary to know their capabilities and understand its way of acting: The conductivity thermal resistance , the thermal resistance and the thermal transmittance .
Depending on the manufacturing process, the materials are distinguished and are organized in:
The guidebook focuses on the following thermal insulating materials :
| Rockwool | Cork | Cotton |
| Expanded Perlite | Expanded polystyrene | Linen |
| Cellulose | Sheep wool | Polyurethane |
| | Coconut fibers | Hemp |
| Cellular glass | Extruded polystyrene | Wood shavings |
In the table that we can see below, list the properties of insulators thermal more common in buildings, which they are:
The document also adds a breakdown of values in more complete tables on thermal resistance with relation to its thickness and a comparison between the range numerical information on the most usual conductivity according to the type of insulating material . (We can also see the glazing guide and glass curtains)
We remind you that acoustic materials and electrical are not considered in the insulation guides in rehabilitation, and assigns the type of material that we have previously verified. The formats of thermal insulators considered in the document are:
The classification of the tables of the materials goes in function of its location (Façade, roofs and partitions) before the different types of thermal insulation , classified into four graphs:
To determine what type of material insulation in the house we need and when use it in the building to be rehabilitated, we only have to see the exceptional graph below (we only add the number "1"):
As we have seen, the two informative notebooks They provide very valuable knowledge, advice and in a way synthesized that will surely come in handy in our work daily.
Both documents belong to the Valencian Institute of Building, where you can visit the portal from IVE. Very recommendable!… Before technical information of the sector of the construction and works.
And by the way, we want to contribute an End of Year project Degree at the Polytechnic University of Madrid that we think interesting from HERE, with explanations, graphs comparisons at the end of the report and what the topic of the insulators and their selection according to requirements energetic .
