Which kind of products and solutions does the building industry offer for improving people's quality of life?

In order to improve people's quality of life, the building industry must guarantee comfort and convenience in the home from both a thermal and acoustic point of view. The industry must prevent noise made by neighbours and from outside, ensuring it is not audible inside the home. Floating systems create double partition walls; floating floors dampen the sound of footsteps, tables and chairs dragging across floors... very light, far more efficient acoustic membrane systems combine different anti-resonance and damping properties to ensure intimacy within the space, among the innovative solutions available for insulating buildings.

Comfort also requires good thermal insulation, and at DANOSA we like to call this hidden comfort. It is important to remember that six in every ten buildings are defective in this respect, which is very serious, because occupants feel cold because of humidity caused by filtration and rain. Users have to turn up the thermostat, which can make heating the home up to 30% more expensive. Make no mistake, windows are not the only place where energy escapes. Another cause of this problem is the roof (approximately 30%), walls (25%) and floors (2%). The solution to all these issues is the same: correct insulation. Although it may seem like a cumbersome solution, a mere one-centimetre layer of styrofoam has the same insulating capacity as an 82-centimetre wall.


What is the reason for this growing search for waterproofing and insulation? What does your company have to offer?

As we are seeing, waterproofing and insulation are essential. They are a small improvement that can make an enormous difference to living conditions in the property. For example, installing soundproofing in a home can reduce discomfort by up to 70%. All this without mentioning that in Spain, 60% of buildings lack sufficient thermal insulation and it is precisely these homes that consume around 20% of all energy used in the country, making them real energy guzzlers.

Really, to resolve the energy inefficiency problem, DANOSA has developed thermal insulation systems designed to reduce energy consumption and greenhouse gas emissions. Their qualities include minimum water absorption, high resistance to heavy loads and an ability to reduce energy bills by up to 50%.

We also want to deal with the environmental noise problem - which has been growing in importance in recent years. We now know about its damaging effects on humanhealth, such as, for example, impaired night vision, fatigue, insomnia... We produce acoustic insulation systems, which are designed to reduce and prevent transmission of airborne and structural noise from room to room in buildings.

We also have solutions which, when installed in buildings, improve air quality, reduce the amount of energy required to heat or cool the inside of a building, reduce airborne noise levels... These are garden structures, commonly known as ‘green roofs’. We present a comprehensive system that minimises the ‘island of urban heat’ effect, helping to save energy for plants to develop correctly, guaranteeing water tightness at all times.

It is also significant that a building’s demand for energy is equal to the energy required for a person to enjoy specific levels of comfort. We are talking about hot water, lighting, climate control... and it is the latter that devours the most energy. Heating and cooling alone account for 46% all the energy consumed in the home. That's why we have designed a roof system that reflects the sun with a white, highly reflective surface that minimises heat absorption, helping to reduce the demand for energy and, allowing more sustainable consumption.

We must not forget the risks to which buried parts of buildings are exposed (for example, walls), such as rain, condensation and run-off, which can have serious effects. For example, waterproofing is vital. We have developed a system to protect and improve drain-off of underground water that penetrates roots for excellent results. It is easy to install and is very durable, among other properties.


How do you think CONSTRUTEC can contribute to improving knowledge of the sector and driving business for companies?

CONSTRUTEC is a powerful showcase for publicising new building systems and draws attention to the fact that this sector, one of the main driving forces of the Spanish economy, is also sustainable, energy efficient and that it has a genuine, firm commitment to the comfort of people.

There's no question that this is a benchmark meeting for architects, builders, quantity surveyors and sector professionals who act as consultants, particularly now that the future for building renovation in our country is improving after years of decline as a result of the crisis. In fact, according to data released by the Ministry of Public Works, the sector grew by 13% last year, showing that renovation is one of the building industry's fastest growing sectors. What’s more, rehabilitation accounts for 66% of all money spent on building.
