DOORS, WINDOWS AND STRUCTURE

There are three levels of protection for a perfectly sealed window or door. Only if all three levels are met when installing a window or door frame, it will it be effective:

1. wind tightness level: the most external level must guarantees protection against weather;
2. thermal and acoustic insulation level: the intermediate level must guarantee thermal-acoustic performance and mechanical fastening;
3. airtightness: it is the most internal level must be airtight.

An improperly installed high-performance window or door frame will compromise the overall performance of the system and disappoint consumer expectations. Thanks to studies and tests, we not only provide you with specific solutions for each of the three levels, but also with all the know-how to ensure the success of your work.

STRUCTURES AND FIRE BEHAVIOUR

When talking about the ability of an insulating material to resist fire, there are two fundamental concepts: the material's reaction to fire and its resistance to fire. The reaction to fire class is an indicator that provides an assessment of whether or not the material contributes to fire. The resistance to fire, on the other hand, indicates the ability of a building element to maintain structural stability during a fire for a given period. The primary purpose of fire resistance is to ensure the load-bearing capacity of the structure under fire conditions.

The characteristics that must be maintained during the action of fire are indicated by three letters:

R bearing capacity, ability of the building element to maintain structural stability under the action of fire.

E tightness, ability of the construction element not to let flames, vapours and hot gases pass-through to the side not exposed to fire

I thermal insulation,ability of the construction element to limit heat transmission to the side not exposed to fire

The fire resistance rating is expressed in minutes, during which resistance under the action of flames must be ensured. The indication of minutes follows the abbreviation REI (e.g. REI120). In the case of non-load-bearing structures, where the load-bearing capacity is not significant, the R factor can be omitted and the minutes can be expressed as EI (e.g. EI90).

AIR QUALITY

The majority of people spend most of their time indoors. This is why air quality in buildings is so important.

Both indoors and outside, we breathe a mix of air and pollutants (volatile organic compounds - VOC) from different polluting sources.

Rothoblaas offers a range of construction materials that respect the environment and improve indoor comfort.
