Insulation of the outer slope polystyrene apartment. Part 1
Just note, friends, if you want to know more about the whole process, you have to be patient and read the two articles. In the first talk about the stepwise surface preparation and cutting of materials, and in the second - the order finishes.
The window on the sunny side. Zapenennuyu slope, in a normal state, however, was not originally embedded outside. When that did not know, but the foam during this time managed to burn in the sun a little bit, so that it gets worse, it decided to warm extruded polystyrene.
Necessary materials
- Extruded polystyrene - 0.5 m
- Reinforcing mesh (density 160) - 0.5 m
- Universal mix for bonding reinforcement and polystyrene - up to 5 kg.
- Primer - 0,2 liters.
- Exterior paint - 0.2-0.3 liters.
polystyrene XPS
Normal foam 20mm for such purposes is also suitable, but I do not use it - at this thickness it is too loose, brittle and creates a lot of waste. Ordered one sheet extruded foam 20 mm (Without beads) - improved version of the ordinary. The area of a single sheet of about 0.75 sq. m
(120 x 62 cm)What on a slope with enough margin. That's what about the material says Wikipedia:"Extruded polystyrene foam is produced by extrusion... Qualitative extruded polystyrene foam has a uniform, closed-structure, the cells having a diameter of 0.1-0.2 mm. "... By conventional low density polystyrene foam insulation performance and ease of extruded polystyrene somewhat exceeds (40 kg per m3), which has a thermal conductivity of 0.038 W / (m * C).
As you can see, I have dissolved the sheet with a knife on 5 bands. Ramp width 12 cm, with a total length of 4.2 meters. One strip turned replacement, it is below and slightly wider than the rest. Then another, during bonding, each of the parties have to cut pieces missing, since the length of the strip 120 cm, and slopes slightly larger.
The smoother the cut strip, the tighter they prilyagut to the window frame.
fit strips
An important stage for a good result. Two bands first drove under the angle of the tide, and then another, made cutouts for vertical bends low tideTo polystyrene lay close to the wall and not how it is bulging. On the third strip made incisions underneath fastening the mosquito net.
It's pretty Morochno nuance, but here I was lucky - got off cutouts. In other cases, I had to reinstall securing mesh and change its position slightly. With this it is to determine as early as possible, before the start of gluing strips on a slope.
Preparation for grid reinforcement
Since the width of the slope of 12 cm, I cut the net almost as wide 11-11.5 cm but not in the cells, and in line (rail). So what exactly is a fragment of a direct and not come out beyond the slope. The outer ends of the polystyrene reinforcing mesh is not, and will cover up the case.
Substrate preparation
From this it was possible to start, of course, but I prefer so, because it makes the job for two days.
Strongly protruding pieces of the solution had srubyvat hatchet and bring down the hammer. But if on the slope, there are serious defects or partially collapsed concrete bridge over the window, you should remove these moments by spending time on the plaster.
Plaster reinforcement may be the same mixture that is bought for bonding polystyrene, only 5 kg have probably not enough.
Well, in the completion of the preparatory work is impregnated OKOS ground. Still there was a residue Ceresit CT17, and therefore it is used.
Almost all sliced and well-prepared ground. Quietly I am going home, and wait for the day of tomorrow, to have something to tell us in the second part.
