Beware of pseudo-professionals
who have the commercial cheek to assert anything and show their incompetence and their complete misunderstanding of basic phenomena
We even agree for
ask professionals to provide the written text of the latest DTUs that they never have and that nevertheless they must respect (2000 to 3000 € to pay to have what they must respect !!!). Even with a legal expert I couldn't get it !!!
He all say yes like us !!!!
Otherwise compared to my fireplace, the dodo fireplace is much more surrounded by wood which makes it more difficult to
insulate it better with copper plates slipped between the wood and the chimney !!!Only safe solution! and planned at DTU as far as I remember ???
but by removing the boards that were used to block the cement in the construction, should we be able to ??? In addition we would see a part of the bricks of the bushels appear.
On the picture there is
a little red in the upper right corner of the fireplace which shows the double wall brick bushel from the 1970s to the 1980s. By looking carefully on the spot, we must be able to confirm !!
You can make a hell of a fire in the chimney and measure the temperature of the beam and the chimney by sliding a thermocuple between wood and cement or brick (small welding of copper wire with millivotmeter).
The beam under the tiles is well ventilated in the cold and therefore well cooled with more difficult to burn wood (much more than polyurethane or polystyrene) !!
I made the involuntary experiment with the very strong lightning which pierced the roof and the tiles, not set fire to the ridge beams but set fire to a rubber much more flammable !!!
On the other hand the insurances, which cover the installers, oblige them to respect the rules of the art of which DTU, ie the rules imposed by the judgments of justice on report of the legal experts.
For 15 to 20 years, given some very old unsuitable cracked chimneys not tested by professionals, the fashion is for the systematic casing of everything with aluminum tubes, accentuated by the industrial lobby which takes the opportunity to sell many more of these casings, which pays more than keeping the chimneys in good condition or repairing cracks with cement.
In addition to repair, requires reflection, skill, understanding, endangered qualities that waste time !!
The casing which brings in money (and pollution in Hungary) requires no reflection, worse we do not even get tired of sweeping the old chimney properly and perfectly (hard work) (ask if it is requested and required by DTU ???? Very important) and we see on the internet a collection of people furious at having had a chimney fire after casing !!!!!
I bet the DTU does not require it to check the quality of the old chimney which, if full of soot and tars, much more heated after casing (for you section 3,5 times lower therefore 3,5 times hotter ) and well insulated between the bushel and the casing catches fire whereas it would not have burned without casing (reason which invites you to take 18cm in casing) !!
Tap on google; casing fire chimney, with variants and read everything thoroughly hundreds of pages, not 12 or 48 but an armada of info, like the DTU hidden somewhere !!

Whenever I sweep my tubing, I ask myself the question and
I am afraid that the brush to be swept will use and pierce the casing in aluminum foil without me realizing it !!!!In my opinion, bushel chimney fireplaces will last much longer than aluminum, which wears out mechanically and degrades by long-term oxidation.
The lobbies often distort the rules and DTU to their advantage to sell much more !!
Herbicides, GMOs and insecticides (and asbestos) are a clear example of Lobbys figuring out how to sell a lot of poisons with clever manipulations, leading to the illusion that what is more dangerous for insects and microbes is not everything dangerous for us however little !!
An incredible and criminal lie with truncated studies over 3 months and never embryos !!!
Search on google if someone had a fire on the beam against the brick bushel with a waterproof chimney ???
If you don't find one, you notice an absurdity
