00:00:01

you are on the channel of the company Dacha Stroy,

00:00:03

today’s video will be from the site

00:00:05

where I arrived at the request of the owners of the house,

00:00:07

the problem was that in the spring of

00:00:11

this year the entire second floor was filled with

00:00:14

condensation, I came to understand the

00:00:17

reason for this phenomenon In this

00:00:22

video I want to show a huge number of

00:00:24

gross violations during the construction of the

00:00:26

attic floor.

00:00:34

I am often asked

00:00:36

questions like this because on my

00:00:39

YouTube channel I have

00:00:42

made videos on this topic many times and

00:00:46

I still want to cover this topic because I sincerely

00:00:48

believe in the fact that you, the future owners of your

00:00:52

future homes, will be able to, at least at a simple

00:00:55

level, control what the builders do to you,

00:00:58

in principle, when I go on

00:01:01

such trips for such requests, I can already

00:01:05

roughly imagine what awaits me

00:01:06

because many times I have already gone to

00:01:08

such measurements, inspections and in principle,

00:01:14

I saw everything that I expected and maybe even

00:01:16

a little worse, let me show you everything now

00:01:19

and tell you how this can be

00:01:21

avoided simply by observing what

00:01:25

they do, sometimes you just need to come

00:01:27

to the sites to supervise the builders

00:01:31

when going up to the second floor of this house,

00:01:34

the first thing that catches you is in our eyes when we

00:01:37

raise the noise upstairs,

00:01:38

these are these smudges, dirty

00:01:43

water smudges, they are on this side,

00:01:48

they are also on this side, and in

00:01:51

fact in many places as the

00:01:54

inspection of the house begins, also what

00:01:58

immediately catches the eye is this that we

00:02:01

see blackness on the boards, this is, in fact,

00:02:08

already a

00:02:10

street board, an exterior finish on

00:02:13

which there was no wind protection,

00:02:16

insulation was simply shoved in there and,

00:02:19

in fact,

00:02:21

without wind protection and without a ventilation gap, it was

00:02:24

clapboarded as it was done here, water

00:02:29

just flowed through the clapboard into various cracks and

00:02:31

I wet the insulation, so there was constant dampness in this place,

00:02:36

which basically leads to fungus. Further, after

00:02:40

listening to the owners’ story about what

00:02:42

the problem was and why they called me, I

00:02:45

find out that we have

00:02:48

only 100 millimeters of insulation on the roof; this

00:02:52

can be seen here, let’s assume that

00:02:55

there is a vapor barrier that was torn off and

00:02:59

you can see that the insulation is

00:03:01

really 100 millimeters and here

00:03:04

right away at this moment we can see

00:03:08

that there is no ventilation gap monogram on the roof of this house; it is

00:03:13

very easy to understand immediately after the

00:03:18

under-roofing film and in this house this

00:03:22

film is ordinary wind protection

00:03:24

which should not be here at all, there

00:03:26

should be an under-roofing

00:03:28

super-diffusion membrane, we see the

00:03:29

board is immediately visible, this is already a

00:03:31

lathing for metal tiles,

00:03:35

if there was a counter-lattice in this place,

00:03:37

then this board would be at least

00:03:39

five centimeters away from the

00:03:42

under-roofing film, I remind you that in

00:03:45

this case here wind protection

00:03:47

wind protection cannot be used as an

00:03:50

under-roofing membrane, everyone needs to

00:03:54

remember this once and for all regarding the

00:03:58

outline of the lathing, I hope you understand me,

00:03:59

the board should be at a distance from the

00:04:03

under-roofing membrane, and in this

00:04:05

case,

00:04:06

the easiest way to understand is that

00:04:10

the counter-lattice is on you your roof

00:04:13

is done if you can see up to the cheekbones immediately

00:04:16

after the rafters and you can safely make a

00:04:18

claim to the builders of your house so that

00:04:21

they dismantle and redo everything,

00:04:24

also about the absence of counter sheathing, you

00:04:27

can understand by looking

00:04:28

at your roof at the eaves of the roof

00:04:31

from below, you can

00:04:32

clearly see that the metal tile is

00:04:38

closely adjacent to the front board

00:04:42

which is made of lining, here there can

00:04:45

be a two-fold situation, such that the

00:04:47

builders, out of ignorance, can simply cover this

00:04:50

ventilation gap with lining or a frontal

00:04:52

board, but here it is

00:04:55

clearly visible that even the film itself is

00:04:58

pieces of film, well, we wash the white strip, it

00:05:01

can be seen sticking out right from under

00:05:03

the metal tiles, respectively there is no

00:05:06

gap there, if there was a ventilation

00:05:08

gap and you would see from here most likely a

00:05:14

50 to 50 block that would separate the

00:05:18

metal tiles with sheathing

00:05:20

from this film, here are the under-roof

00:05:23

membranes,

00:05:24

and as for the insulation

00:05:28

that is done here in millimeters I

00:05:30

have already said this for the northwestern

00:05:34

region, it is believed that the insulation standards

00:05:38

are 200-250

00:05:41

millimeters, the thickness of the

00:05:46

basalt or mineral wool insulation, the

00:05:51

next point is the vapor barrier, the

00:05:56

vapor barrier here at this facility is

00:05:58

used an inexpensive brand,

00:06:03

this is all the vapor barrier with the marking b, this is

00:06:08

exactly the vapor insulation that is with one

00:06:09

side is smooth, the other side is a ball

00:06:12

of shaving, and for those who still don’t

00:06:17

know which side such a

00:06:18

vapor barrier is mounted on, then this is done with the smooth

00:06:21

side facing the insulation, the

00:06:22

rough side in the room is done and

00:06:28

this is precisely so that condensation,

00:06:31

which in theory can form on

00:06:34

the vapor barrier, can be better linger on the

00:06:38

rough side of the vapor barrier and in this

00:06:43

state do not flow down somewhere but

00:06:45

dry out in the place where it formed

00:06:49

if such a situation happened,

00:06:52

so I thought for a very long time

00:06:54

how and why it was done here

00:06:58

exactly like this, if we look at the whole

00:07:01

vapor barrier it is wrapped in

00:07:06

front rafters, but then I realized what was

00:07:09

going on, those who did this work, they

00:07:14

used rolled out the vapor barrier not

00:07:17

horizontally but vertically, packing

00:07:20

each layer of vapor barrier between the

00:07:23

rafters, that is, from here to here,

00:07:26

they packed it into a separate, well, it turns out

00:07:29

into a separate sheet, and thus

00:07:31

they got it each place saw

00:07:34

distance is packed separately in a

00:07:37

vapor barrier only then I noticed, in

00:07:41

fact, the dotted line, yes, this is the

00:07:43

dotted line by which the overlap of

00:07:46

the blade is determined and I realized that they simply

00:07:48

turned

00:07:49

the roll the other way around and started doing it

00:07:52

vertically, despite the fact that

00:07:56

apparently they even did it at this site these are different

00:07:58

people because here it was done like this,

00:08:02

we turn it over to the other side there,

00:08:05

the film is already on the other side, nothing

00:08:08

was wrapped, no one no one

00:08:11

glued anything in this state, it’s all

00:08:15

left here, that is, this is this,

00:08:18

this is not a glued vapor barrier, although

00:08:23

in principle there is even an adhesive

00:08:26

adhesive strip that should help

00:08:29

do this, but alas,

00:08:36

accordingly, in the vapor barrier all over the

00:08:39

entire second floor, there are such holes

00:08:44

somewhere, something has already fallen off and this

00:08:46

vapor barrier is not working, we can go

00:08:50

look at another room,

00:08:54

that is, these are the most difficult places

00:08:56

like this Packed in this way, we can

00:09:05

say that in this case, the vapor barrier

00:09:07

was done only so that the insulation

00:09:10

and dust would not fall on the owners’ heads, but

00:09:16

for its intended purpose it does not

00:09:19

work here. People tried to assemble it all with

00:09:22

paper tape and

00:09:24

glue it all together in this room. By the way, it’s

00:09:26

more

00:09:30

paper. adhesive tape,

00:09:31

but in reality it doesn’t work, they

00:09:34

only glue films with

00:09:36

good specialized adhesive tape, there are

00:09:39

even recommendations written here for those

00:09:43

who do the installation about what needs to be

00:09:49

taken into account when installing a vapor barrier, but

00:09:55

I don’t think it’s worth talking about the fact that all the insulation along the rafters is crumpled by hand

00:09:58

somewhere it’s just written down in pieces, but the

00:10:05

most important thing is when we come and

00:10:09

look at the pediment, what kind of sticks it’s

00:10:14

assembled from, for me it’s just, frankly speaking,

00:10:18

a shock, this is what the

00:10:20

pediment of a residential building looks like here,

00:10:32

you can judge for yourself,

00:10:34

I think there’s no need to be very

00:10:37

professional here in order to understand that

00:10:40

this is not very normal, but also the insulation

00:10:46

of this whole thing is, again, here

00:10:47

there are 100 millimeters of insulation,

00:10:51

which for some reason on all

00:10:56

the racks is again pressed like this

00:10:57

and then I figured out why this is

00:10:59

happening because the pediment frame is

00:11:03

assembled from a board of 50 millimeters, by the way,

00:11:07

now, and I’ll even show you

00:11:13

here, you can see there, the

00:11:17

street itself is already glowing, the

00:11:19

frame itself to the pediment is from this 50

00:11:23

board, from this one, then insulation was laid,

00:11:29

then a vapor barrier was laid on top of it, then

00:11:32

all this was pressed with this

00:11:35

second board

00:11:36

which creates the appearance of a counter,

00:11:42

so when I just walked in, I first

00:11:45

thought that it was a fair shot 100 to

00:11:47

100,

00:11:48

but it turned out that it was so, this is what

00:11:51

struck me most of all, and

00:11:53

accordingly, such moments, yes, that is,

00:11:58

this is the level of construction in Russia that

00:12:05

can be achieved evaluate,

00:12:10

well, the owners of the house have no complaints

00:12:13

because they bought this house

00:12:15

here, even in a couple of rooms the finishing was already

00:12:17

done, all this was already

00:12:21

revealed after the opening, what

00:12:24

struck me most was this

00:12:26

pediment, everything was done here exactly the same

00:12:32

as on the previous pediment, but here

00:12:35

there is a wall that actually killed me, that

00:12:38

is, who I hope you can see because

00:12:41

these white

00:12:45

gaps are shining and this is the 50 board that

00:12:51

this pediment consists of and it’s just that on this

00:12:54

pediment no one sewed the second board on top onto

00:12:55

the vapor barrier

00:12:57

and therefore here it is from From this we can

00:13:00

conclude how that pediment is assembled, just a

00:13:07

fifty-kopeck piece of insulation, such as

00:13:12

cubes, is placed there, closed with a

00:13:14

vapor barrier, just a vapor barrier is pressed

00:13:17

against this to this stand, and that’s the whole

00:13:21

structure;

00:13:25

also on this pediment, you can see the

00:13:29

degree of quality of the insulation, that

00:13:34

is, you can see how they shine through

00:13:36

the vapor barrier. these are the cracks, the gaps

00:13:40

here, in general, David, there is a hole on the street,

00:13:50

air is blowing from all these cracks, but

00:13:53

again you need to understand that in this

00:13:55

place where we have these supposed racks,

00:14:02

the insulation has been removed so much that in this

00:14:04

place it is practically not there, that is, it is

00:14:06

here again this street doesn’t work like that,

00:14:14

well, now let’s talk about what

00:14:16

I proposed as a solution, but this

00:14:20

solution will be intermediate in order to

00:14:23

save the initial budget and not

00:14:27

disrupt any global work

00:14:30

there, suppose there is a second floor

00:14:32

and so on in the comments you can

00:14:35

estimate how much Do you think such

00:14:38

solutions are relevant given this

00:14:40

problem and so 1 owner completely on his

00:14:45

own, accordingly, dismantles all

00:14:48

this vapor barrier, insulation, everything that

00:14:52

can, yes, perhaps these are on the

00:14:54

interior partitions

00:14:56

because they will interfere with us when

00:15:00

redoing this whole thing,

00:15:01

then we will have to first in total,

00:15:06

we will increase these racks and we will also

00:15:13

increase the

00:15:15

rafters by 50 or 100 millimeters in

00:15:21

order to increase the thickness of the insulated

00:15:24

layer,

00:15:26

then we will completely remove, and

00:15:32

accordingly, the owner will remove all the

00:15:33

insulation

00:15:34

from the top of the roof and we will

00:15:37

make the ceiling

00:15:38

along the beams, that is, in more in the classic

00:15:42

design, the ceiling will now be

00:15:44

horizontal, so due to

00:15:46

this,

00:15:47

we will increase the ceiling by about another 100

00:15:50

millimeters, exactly the upper part of

00:15:54

the roof, this will all remain without

00:15:57

insulation, it will be a cold,

00:15:59

unused attic, in order to

00:16:03

ensure ventilation of this attic we

00:16:05

will make checks on the pediment on small

00:16:10

there are three gables on the ventilation grille,

00:16:12

so on 3

00:16:14

gables there will be ventilation

00:16:16

grilles

00:16:18

further on, I think that we will have to

00:16:22

redo the frame of the gables,

00:16:27

since on the first floor of this house the

00:16:29

facade has already been finished with imitation

00:16:31

timber,

00:16:33

then I think that on the second floor it will be possible to

00:16:37

redo the pediment and continue

00:16:40

this imitation of timber already along the pediment,

00:16:43

this whole disgrace needs to

00:16:49

be redone, after which we will install

00:16:53

normal racks, I think that it will be

00:16:54

a hundred and fifty to fifty board and

00:16:57

additionally along the pediment, if

00:17:01

possible, if it is possible, it will be possible to

00:17:03

cross-insulate these pediments with another 50 millimeters

00:17:06

then to do the finishing,

00:17:10

this concerns the gables of the nose,

00:17:13

in fact, then our task will be

00:17:16

to make a high-quality vapor barrier, that

00:17:20

is, we will completely tighten everything as it should

00:17:23

be,

00:17:24

we will glue all the connections, all the overlaps, and that

00:17:30

means this will be the first stage of work after

00:17:33

that, as he sees it, we will leave these

00:17:37

rooms before next spring to

00:17:39

see how much the problem will be solved,

00:17:43

plus the owners will also start heating on the second floor

00:17:45

and we will watch and

00:17:48

observe since we have obvious and

00:17:50

very gross violations on the roof, that

00:17:52

is, there is no ventilation gap and the

00:17:54

outline of the sheathing is precisely for this

00:17:57

reason we will wait to see what

00:17:59

will happen

00:18:01

if the problem continues,

00:18:05

then the roof will have to be redone.

00:18:08

Now the owners are

00:18:12

not ready to fit into such work because the budget

00:18:15

there will be completely different,

00:18:17

so we are going step by step, here is the

00:18:23

work plan. Another thing that really

00:18:28

upset me is that looking at this

00:18:30

pediment and having visited Inside this house, I

00:18:32

understand that the clapboard is nailed directly onto

00:18:36

the frame of this pediment, in some places

00:18:40

there is wind protection, in some places there is

00:18:43

none, that is, again, there is no sheathing, so there are no linings on the slopes,

00:18:48

no ebb tides, and

00:18:52

during rain it is obvious that water

00:18:56

is pouring in in general, the whole thing can only

00:18:58

mean that the entire insulation also

00:19:00

gets wet and remains there in a wet state

00:19:04

because it is almost impossible to dry the insulation,

00:19:07

that is, for

00:19:09

this you need to disassemble everything,

00:19:11

you need to lay it out in the sun, it

00:19:13

must lie there for a long time without

00:19:15

rain without anything and dry out, this really makes

00:19:18

me very The whole story is also very

00:19:20

upsetting in this house. I also didn’t

00:19:23

say that perhaps in these

00:19:25

rooms it will be necessary to

00:19:26

install a

00:19:28

supply and exhaust valve, that is,

00:19:30

ventilation must be

00:19:32

present,

00:19:33

or that is, you will have to constantly

00:19:35

ventilate these rooms through the windows of the stage

00:19:37

or install some kind of at least a

00:19:41

little - a little bit,

00:19:42

but ventilation on this, in principle, that’s all

00:19:46

I wanted to tell you from this

00:19:48

object,

00:19:49

if you were interested and perhaps

00:19:51

useful, like, subscribe to

Description:

Как нельзя строить мансарду, об этом мы поговорим в этом видео. Я покажу Вам почему на мансарде появляется конденсат, грибок и холод. Я приехал на этот объект по просьбе Заказчика, который рассказал о том, что по весне в его доме появился конденсат на мансарде. По приезду я увидел то, что и ожидал увидеть в такой ситуации. Везде подтеки конденсата, грибок и чернота. Утепление мансарды сделано всего 100 мм базальтовой ваты. Пароизоляция использована самого дешевого сегмента, да и в добавок вся порвана и не проклеена. В общем на этой мансарде есть все косяки которые только могут быть при строительстве мансардной кровли.
