Imagine your house was like a balloon. If it had holes, no matter how small, the air would eventually escape and Keeping him inside would become a real mission impossible.. Well, that's precisely what airtightness in your home is all about: keeping the air in (and keeping it out). This is one of the best-kept secrets of comfort and energy savings. Today, at Modular Home, We want to talk to you about airtightness in homes And how our industrialized concrete houses are leaders in this regard. Take note!
What does airtightness mean in a home?
Airtightness is the ability of a house to prevent unwanted air infiltration, that is, those currents that sneak in through cracks, joints or poorly fitted windows.
The goal of good airtightness is to achieve a well-sealed enclosure to maintain complete control over the air entering and exiting. This way, the Heating or air conditioning system works less and you spend less, what translates into traditional comfort and a smaller number on your monthly energy bill.
Factors that influence the airtightness of a house
There are different factors that determine the effectiveness of a house's airtightness.
Quality of the thermal envelope
The thermal envelope is like a home's outer shell. Loose seams let in cold air, so the materials used in walls, facades, and roofs must be precisely joined to ensure continuous and long-lasting insulation.
Windows and doors
High-performance carpentry, with good glass and multi-chamber frames, are essential, since They not only insulate against cold and heat, but also block noise and leaks.And if they're made of PVC or aluminum with thermal break, even better.
Sealing of joints and construction encounters
The junction points between different materials are critical locations, as a poor seal can become a highway for outside air and heat loss. This is where the airtight tapes, expanding foams and sealants that guarantee a perfect union.
Execution of the work
You can have the best design and the best materials, but If during the work the execution fails, the airtightness also failsConstant quality control and assembly protocols are just as important as the initial project.
Benefits of an airtight home
There are several benefits of an airtight home that influence comfort and savings, as well as in the reduction of external noise.
Energy efficiency and savings in heating/cooling
An airtight home keeps the indoor air where it should be. Thus, air conditioning systems work less, which reduces energy consumption and the cost of bills.
Thermal comfort all year round
No more having one room that's freezing and another that feels like a sauna. With an airtight home, temperature remains stable in all spaces.
Improved indoor air quality
Good airtightness combined with controlled ventilation systems guarantees a cleaner air, without dust, pollen or pollution urban sneaking into the house.
Reduction of external noise
Seals and insulation not only prevent air leaks, but also They function as an acoustic barrier, which is ideal for those who value peace and quiet in their home.
Hermeticity and sustainability
Airtightness is not only good for your wallet, but also for the planet. By reducing energy losses, They reduce your carbon footprint and help your home comply with European regulations. energy efficiency.
It is also a firm step towards Passivhaus standard, the model of passive houses that barely require any energy to operate.
How to measure the airtightness of a home
As you can imagine, the control of airtightness in a home It is not something that is left to the whim and free will of each person., but follows strict standards measured through the following procedures:
The Blower Door Test
Did you know that air tightness is measured with a giant fan? The Blower Door Test seals the house, creates a pressure difference and measures how much air is leakingThe lower the result, the more airtight the home.
Recommended standards in Spain and Europe
In Europe, houses that aspire to Passivhaus certificate must reach very low air leakage valuesIn Spain, regulations also promote increasingly efficient construction, in line with the sustainability goals set by the European Union.
Airtightness in Modular Home's modular homes
At Modular Home, we don't leave airtightness to chance. We integrate specific solutions from the very design of our prefabricated and industrialized concrete homes. We use High-quality materials, precise joints and our own construction method (MH System) that guarantee a perfect seal, literally from the factory.
This strict production control allows us avoid typical errors in traditional construction and ensure superior thermal performance once the home is installed.
Get your industrialized home with the best possible airtightness
The time has come for you to stop seeing the airtightness of your home as a luxury and turn it into a smart investment that offers you comfort, savings and sustainabilityIf you dream
With a home where silence, thermal balance, and low bills reign, we help you take the first step. Contact us to start building your industrialized housing of concrete, sustainable and perfectly sealed to live better and, above all, breathe easy.
