The proceeds from this video will go to UNHCR, to help refugees in Ukraine. Thank you for sharing! ❤ ❤❤ Step by step guide to thermally insulating a wall from the inside with the Beissier Therm In system, which improves energy efficiency while taking up less space than conventional linings. http://www.bricocrack.tv Tutorial Construction Thermal insulation Insulating a cold wall Install SAT Interior Energy efficiency All products shown in the video are from Beissier. More information about the Beissier Therm In Interior Thermal Insulation System on their website: https://www.beissier.es/es/inteiror/s... The work clothes, gloves and footwear we use are from Tomás Bodero Group: https://tomasbodero.com/es/. Here you can see the catalogue of each of their brands TB, BeeWork and Cerva: https://tomasbodero.com/es/content/ma... Sometimes installing a SATE is not viable, either because the neighbours do not agree or because the historical value of the façade prevents it. For these cases, there is another option which is to install a thermal insulation system on the inside. We are going to use Therm In by Beissier which, compared to conventional insulation systems, has a very important advantage which is the little space it takes up from the room once installed. With a total minimum thickness of the system of 15 mm, it provides us with an improvement of up to 40% of the thermal transmittance of the wall on which it is installed. And this improvement can mean up to a 20% reduction in the energy demand of the home, that is, the heating costs. As with other Beissier products, we have made this video with the support of their Technical Department and they have allowed one of their application and training specialists, Sebas Martínez Roberts, to show us how to install this system. And, in addition, Beissier has proposed a ????????DRAW???????? to reward one of our followers with all the necessary materials to install this system in a room in their house. To participate, you just have to tell us in the comments that you want to do it and what insulation work you would undertake with these products if you were lucky. You have until April 4 and the only limitation is that we can only send it to the Iberian Peninsula and the Balearic Islands. If you are a professional and want to learn more about this thermal insulation system by participating in a Beissier training course, contact them here: https://www.beissier.es/es/contacto/c... We remind you that the Beissier Therm In results are guaranteed as long as you use all the products included in the system, you cannot do without any of them or replace them with products from other brands. Let's go step by step! ONE. If your wall needs it, you will have to make the appropriate prior repairs and remove the skirting board. With the wall ready, we place the 9 mm thick Beissier Therm In panels. We start at half height so you can see it better but you can start from the floor if it is well leveled. We glue the panels with Beissier BMB 12002 mortar and an 8 mm notched trowel. We work in 2x2 m2 panels so that the mortar does not dry out or lose adhesion. It is very important to check the levelling of the panels and to ensure that there are no gaps in the joints to avoid thermal bridges. The joints between rows should always be offset by at least 20 cm. TWO. Once the mortar used to glue the panels has dried, we apply a reinforcing layer of the same mortar with a 6 mm notched trowel. And in this layer we soak the Beissier fibreglass mesh. The mesh strips do not overlap. THREE. Once the second layer of mortar has dried, we scrape off any burrs and apply a third layer of the same mortar with a smooth trowel. This is a smoothing layer and, if necessary, a finishing layer can be applied. FOUR. Once all the layers have dried, we apply a coat of Beissier Fixacryl primer. When it is dry, we apply the Beta Therm In paint that is part of the system. It serves as a final finish and reinforces the thermal insulation because it prevents the cold wall effect. Tell us in the comments of the video what you think about this Interior SAT and remember that on March 22 we have a new live on YouTube with the architect Aitor Echeverría.
