Thermal insulation cork panels

WHICH INSULATING PANELS TO CHOOSE?

We have chosen green building! Because with natural insulating panels we will have a healthy and comfortable home without risk to our health: among the many natural materials available we have chosen cork panels and wood fiber panels because, in particular cork adds all the qualities that a panel insulation must have:

 


        -Excellent thermal insulating capacity
        -High density which also means protection from the summer heat
        -High breathability
        -Excellent quality of acoustic insulation of rooms.
        -Excellent resistance to compression and impact

 

INSULATION PANELS IN BLOND CORK OR TOASTED BROWN CORK?

The blond cork insulation panel is made by hot pressing ground cork with a modest amount of adhesive, while the brown cork manufacturing process provides for a much higher temperature which expands the granules and causes the cork to escape (the natural internal resin contained from cork): the high temperature expands the cork which is self-glued thanks to the natural cork thermal insulating panels thermal cork jacket

The opinions on the degree of "naturalness" to be assigned to the two types of cork panel, blond and brown are not always in agreement: if in principle toasted brown cork is considered more natural because it does not contain added glue, it is also true that the process at very high temperature changes the physical structure of the cork, while the blond cork maintains a more natural shape and appearance.

Current research in this sector aims to produce an even more ecological cork panel that does not contain synthetic glue and that does not change the appearance, consistency and characteristics of the cork.

WOOD FIBER INSULATION PANELS

The Gutex wood fiber panel is obtained from the processing of timber from the Black forest respecting all the strictest European standards (see the brands) the wood fibers are shredded and pressed after a felting process that allows phono insulating panels to agglomerate without use of added adhesives. wood fiber for roof insulation

Modern manufacturing techniques allow the production of a wide range of panels with very different characteristics for different uses: rigid or flexible panels for roofs, light or high specific weight panels, wooden panfibre for the insulation of the tettoni with density and surface treatment for the "thermal coat", compression-resistant panels for substrates.

WHERE TO CREATE THERMAL INSULATION?

The insulating panels must be positioned throughout the housing "roof": roof, walls (even those bordering another house) and sub-floors. The choice of thicknesses to be used must be made considering the percentages of heat loss of the various parts of the housing, in the table below we report the average percentages of heat loss relating to the various parts of the housing. The values ​​shown are an average of very discordant values ​​reported by different authors:

HOW TO CHOOSE THE THICKNESSES TO BE USED IN THE VARIOUS PARTS OF THE ENVELOPE?

Many of our customers do not have clear ideas on how to proceed with the choice of the thickness of the insulating panels: we recommend that you always carry out a thermal calculation on the various parts of the casing so that the proportions and values ​​required by current regulations are respected. If you do not have a "thermal project" because the house is old or because the intervention you want to carry out is modest and does not require any authorizations whatsoever: our technical office will help you choose the best insulating panel and decide on it. thickness.
 

HOW TO MAKE A GOOD THERMAL ACOUSTIC INSULATION OF THE ROOF?

A good rule is to create a continuous insulating package, not divided by a strip, which would constitute a "thermal bridge" through the insulation, thus favoring the heat dispersion of part of the heat. The insulating panels for roofs used must be laid in several layers or with a special joint in order to guarantee the compactness of the insulating package. In the images below are visible insulated roofs with cork panels and with wood fiber panels roof insulation with cork insulating panels

Particular attention should be paid to the wooden roof which needs an insulating package of adequate thickness and "weight" which is easily obtained with cork and wood fiber. This particular value to consider is the "thermal displacement" which is measured in number of hours: in short, the value indicates how many hours the roof resists the passage of heat from outside to inside the house.

Both the cork and the wood fiber give the wooden roof (in itself very light) a good thermal displacement value, unlike the petro-derivative panels which have little effect in this sense. Recall that the legislation indicates in 12 hours the value of thermal displacement to be achieved in order to have a roof that guarantees warm in winter and cool in summer.

Together with the natural insulating panels, it also purchases the under-insulation sheaths and the breathable protective sheath

HOW TO REALIZE A GOOD THERMAL AND ACOUSTIC INSULATION OF THE PERIMETER WALLS?

Over the years the construction techniques have changed a lot and also the thermo-acoustic insulation of the walls has taken on very different forms, we examine the most common cases that generally concern the "renovations" of houses already built but which required an integration of thermo-acoustic insulation :

1. Walls in load-bearing walls of solid and hollow stones and / or bricks:

to improve the thermal insulation of these walls, an external or internal thermal coat is made with cork or wood fiber panels suitable for finishing with natural lime adhesive / skim coat.

2. Reinforced concrete structure with double curtain wall in perforated bricks with cavity:

after evaluating the possibility of insufflation into the cavity, an internal coat is always advisable to correct the "thermal bridges" caused by the presence of reinforced concrete pillars and beams present in the walls (an external thermal coat would always be better, but realistically almost never feasible) In many cases these walls already contain an insulating panel or mat, usually insufficient or prematurely degraded due to poor quality of materials or bad installation.

3. Walls with load-bearing brick walls:

these houses are generally newly built and need a thermal requalification which is obtained with external or external coat

 Together with the cork or wood fiber thermal insulation panels, it also purchases the necessary accessory materials, in particular Bioart-leveling adhesive in natural hydraulic lime to create a healthy and breathable thermal coat (without the use of cement products)

HOW TO MAKE A GOOD THERMAL INSULATION OF THE SUBSTRATES?

As mentioned, the thermal insulation of the floors is also important to avoid the downward dispersion of the internal heat of the rooms, even greater attention to be paid if the heating system is on the floor where the downward dispersion of the heat produced is more likely .

The cases that arise are generally of three types:


1. Thermal insulation during the radical restructuring phase where the subfloor on the ground floor is structured starting from ventilation with crawl space or igloo and insulated with acoustic and thermal insulating panels of adequate thickness. Unlike in the past, today "dry" subfloors are also practiced which avoid the concrete screed above the insulating package.

 

2. Insulation on the inter-floor slab where the low thickness forces you to choose even very small thicknesses but which nevertheless improve the previous situation.

 

3. A very recurring case is the laying of "floating" flooring which offers the opportunity to interpose an insulating layer underneath the new flooring, in this case we recommend super-compressed cork for its undoubted thermal and acoustic insulation qualities: recommended thicknesses range from a minimum of 3mm to 10mm thick.
