In recent years people have acquired more knowledge regarding energy saving legislation and certification in real estate unlike that regarding noise abatement norms and certifications thus taking for granted that one should put up with a noisy next door neighbour.


Listen to the silence.

We have always placed great emphasis on all aspects involving noise abatement in our constructions. We are now proud to have defined a specific construction  technique named “box in box noise control” that is integrated in all our projects, granting  an excellent level of noise abatement. The “detached home effect” phrase was coined since.


'BOX IN BOX' noise control technology
What is the meaning of box in box?

  • Such technique, named “box in box”, whereby every residential unit is considered an independent cell, surrounded on each of its six sides (floor, four walls and ceiling) by supporting walls.
    Box in box
    Obtaining the noise abatement values between residential units, foreseen by the current legislation (Dpcm 5/12/1997) is not OUR objective but our starting point. From here stems the innovative construction technique named “BOX IN BOX”.
  • The supporting structure of the 4 walls and the suspended ceiling is fixed with anti-vibration joints.
    Second Skin
    Using high quality dry materials, a “second skin” is created and is inserted in a suspended manner not attached, but ideally suspended within the main envelope from a suspended flooring that rests on a sound proof mattress.

    Detached home effect
    This innovative technique allows for a very high sound proofing both among units on the same floor as well as units on lower and upper floors. This condition is usually unobtainable with normal techniques. We can therefore coin the phrase of a residential unit with a “Detached home effect”

By applying this technique , a drastic noise reduction in all its frequencies, for example:

  • noise from compling (heels, balls, pulled chairs, etc.)
  • airborne noise (TV or loud music, voices)
  • domestic equipment noise (water circulation, WC)


This means that you can live in the quietness of your home without perceiving any difference between a partying neighbour or an absent neighbour”.

comfortcooling system

Modern homes today are air tight in order to reach very high levels of energy efficiency. However this also implies very low levels of air exchange of air tight spaces. There is an insufficient exchange and a difficulty in adjusting the “degree of humidity” as well as  a presence of domestic toxic substances (detergents, cooking, polluting elements that radiate from different materials, furniture and accessories, and presence of radon gas).

the importance of clean air
in closed spaces

  • Due to indoor pollution and the insufficient air exchange in closed spaces, the percentage of oxygen may decrease to very low levels for our comfort and health whilst the rate of carbon dioxide can increase to much higher values
    In closed spaces
    As we spend over 70% of our time indoors, both at home and in the work place, we are over exposed to the above risk.
  • The air pollution of closed spaces is not simply the biological result of the metabolic activity of both humans and animals (production of carbon dioxide, organic compounds and water vapour) but also the chemical pollution from toxic substances contained in construction materials, in furniture, in combustion as well as from the use of detergents and in that of the pollution resulting from the presence of ionizing and non ionizing radiations, and from humidity.
    Air pollution
    This exposure not only may cause various pathologies such as asthma , allergies and bronchitis but also a stream of effects on our health that are not easily identifiable and that can be associated with a general sense of psychological distress and physical illness as well as lack of concentration.
  • The evolution and technical developments in the construction industry – aimed at energy efficiency – have given us various comforts but also confined us to more enclosed, isolated and hermetic spaces and where the air that we breathe is less than ideal.
    Our homes are inappropriate to everyday life and work if we consider the unhealthy quality of the air in closed spaces added to other aspects such as temperature, airspeed, humidity and ventilation.

the only realsolution

To overcome and eliminate the high concentration of pollutants in our home is to install the only adequate permanent ventilation system supplying continuous clean air to all the spaces and at the same time diluting and removing all pollutants and creating a healthy and comfortable space.

the coolingsystem

Becomes the lung of the indoor spaces and is totally integrated in the construction. The combination of building ventilation system operates in order to recreate the proper indoor conditions depending on the outdoor conditions. This indoor microclimate is adapted to indoor life and is flexible to any activity carried out indoor.
The most appropriate terminology for a home equipped
with this technology is undoubtedly “THE HOME THAT BREATHES”

All of Crema Costruzioni snc projects have the option of incorporating a ventilation system apt to solve all the above problems and making the home a “house that breathes”.
The same system can be equipped with filters to avoid the input of pollens and pollutants.
