I have been thinking about how to improve the energy efficiency of my house, a floor built around 1989, with all the lack of thermal and acoustic insulation that this entails, my purpose for this year is to insulate my floor correctly from the cold and of heat, to contribute as much as possible to the sustainability of my family and in the process save some euro in gas and electricity consumption.
My biggest problems of isolation are mainly the windows, the facade that is exposed by two faces to the outside and the floor, since I live on a first floor on the parking lot and the floor of my house is on the slab that in turn makes roof to parking. This slab has not received in its lower face any insulation treatment, it is more, not even plastered, with the loss of energy and lack of passive insulation against the fire that this entails.
To solve the problem of facade insulation, hired a company specializing in thermal insulation of facades to blow rock wool into the air chamber of the building.
To solve the insulation of my floor or in other words, the roof of the parking lot, I have asked permission from the community of neighbors to project the part of the roof that corresponds to my home and in this way in addition to insulating against the cold , I will ensure that the part of the floor of my home complies with the regulations, which will allow my home to be insulated against fire for a minimum of 2 hours.
Thermal Insulation alternative to Pladur
I have made the determination to thermally insulate and improve the sound insulation of my entire house, though, knowing that if I wanted to acoustically insulate it correctly, the treatment would be much more complex.
As I cannot do it all at once, I have chosen to start with the insulation of the exterior facade. For this I have chosen to blow rock wool into the air chamber of the facade, a much faster and cheaper solution than to build a plasterboard flooring, since we avoid building the walls of laminated plasterboard, with the cost and the loss of space this implies
The technique of insufflated rock wool requires a machine that I do not have, which is why I have turned to a company of my confidence. The system requires a machine with a generator that must be on the street, this machine injects air under pressure with a certain amount of rock wool into a hose. This hose is driven from the outside to one of the windows of the house to be insulated and once introduced inside the home, it is embedded in the perforations made in the partitions of the exterior air chamber, to proceed to its filling with the Lana de Roca, on this occasion, the insulating material used is Rockwool rock wool.
