New technology for floor insulation with penoplex

If you have started a renovation and still haven’t decided what material to use for the floor, then this article will be useful for you. In it we will look at an inexpensive, but at the same time with many advantages, method of insulating the floor using Penoplex. Recently, it is often used in construction, including in the manufacture of floors.
It's worth mentioning this material briefly. Unlike polystyrene foam, it is more durable, has higher thermal conductivity, vapor permeability, zero water absorption, and is also resistant to microorganisms. All these properties make this material suitable for floor insulation.

Insulation of floors with penoplex


So, first you need to dismantle the old floors - linoleum, parquet, etc. In apartments, the base of the floor is screed and concrete, and in private houses it can be wooden boards. If both are in good condition, then there is no need to change anything. The illustration shows an example of a private house where the floors were wooden, but they were in good condition. If the wood is rotten, the floors must be removed and the screed filled with concrete.In apartments everything will be much simpler. Most often, it is enough to just remove the damaged coating, after which you can begin insulation. If the floors are wooden, then you can additionally screw them with screws to the lower beams, since over time the nails could weaken the fastening. This is to prevent them from squeaking.

Calculate how much material you need. Since Penoplex sheets come in different sizes, calculate the square footage of the room’s floor, and in a hardware store you can determine how many sheets are needed. The same applies to OSB boards.

Next, you need to select the highest point (corner) in the room, and start laying the floor from there. This can be determined with a building or laser level. At the highest point, the layer of polyurethane foam should be minimal. The corners of the wall and floor must be covered with foam for waterproofing. Next, polyurethane foam is applied to the floor surface, after which a sheet of Penoplex is laid on it. Using a building level, it is necessary to level the sheet by lightly tapping it with your hand. Before applying the foam, you can wet the floor a little with water so that dust does not repel the foam. If the height of the ceilings allows, and you have the opportunity to raise the floors, then you can use wooden slats 2-3 cm thick to level the floor surface. The slats are screwed to the floor level, and between them there is a row of penoplex.

In this way, subsequent sheets of penoplex are laid. You can cut this material with a regular construction knife. You will also need a tape measure to measure the dimensions that need to be cut. It is best to use a special gun for polyurethane foam, as this will be economical.If you use ordinary foam containers, then after opening it, you must use it immediately, otherwise it will harden. The gun can be used for several days.

After you lay the sheets of Penoplex, and the foam on which you place them has hardened, you need to fasten the Penoplex to the lower wooden floor with self-tapping screws. It is better to use longer self-tapping screws. Before tightening the screw, drill holes with a drill. However, you do not need to tighten the screw completely. These screws must be tightened level. All self-tapping screws must be screwed in a row with an indentation of 20 - 30 cm. The OSB board will subsequently be placed on them.

When all the screws are screwed in, the penoplex also needs to be covered with foam, including around the screws, and an OSB sheet must be placed on top. Thus, it rests on the screw heads and foam, which, when hardened, will hold the slabs.

After this, you need to wait a little until the foam hardens, and then tighten the screws again to the OSB boards to fasten them. The indentation when tightening the screws should be 20 - 30 cm. The OSB must be fastened with the waterproof side up.

The advantages of this technology for laying and insulating floors are that it is not an expensive method. This is much cheaper than using concrete to pour the screed. Also, laying such a floor is carried out in a maximum of one day, if the room has normal dimensions. If necessary, such floors can be easily dismantled.

    Are you seriously suggesting that people stuff flammable insulation into combustible materials, which, moreover, during the same combustion, releases toxic gases!? Extruded polystyrene foam is a good material, good insulation. But it can only be used in residential construction if it is covered on all sides with fireproof materials. For example, poured into a screed. Or outside the house.

      This is a good option for insulating a mother-in-law's house.
      And if the firefighters and the prosecutor’s office don’t find any intent, they won’t find anything.
      IMHO

      in the construction of houses they still use a bunch of flammable materials, if you don’t know...log houses consist entirely of wood (strange as it may seem), modern frame frames are foam walls, floors and ceilings sheathed on the inside, most often with OSB, and on the outside with OSB or DSP...The ceiling is wooden beams and boards are sewn on them...the floor is the same...so what are we talking about

    very unreliable method!) after several months of walking on the floor and still furniture, the slaps of the self-tapping screws will cut into the smallpox and everything that I did was “down the drain”, and “money down the drain”!

    the board under the penoplex will rot. a waste of money

    Great post.
    Having seen something like this, I definitely drove the author away from my private home with a nasty broom.

    Even offhand:
    1- In the event of a fire (and here the floors are wooden), everyone is guaranteed instant poisoning and no one will be able to jump out of the house.

    2- In fact, there is a wild consumption of foam, on which and on the heads of the screws: the slabs are held, taking a variable load from walking people, a constant load from furniture plus temperature changes...

    Is this serious?

    This is how the floors look...

    P.s.
    Beams 50*30 or similar across the floorboards with a distance of 30-40 cm and glass wool between them. On top of the slab.

    Much cheaper, faster and safer in the end. And by the way, mice won’t bother you.

    Read this article and never do this again! Expanded polystyrene in residential buildings can only be “rolled” under a concrete screed, without any options. The concrete base must first be prepared and leveled. It is also better to hide polystyrene foam outside under fireproof materials, for example using wet facade technology. Expanded polystyrene, even in a calm state, releases toxic substances. This is a good insulation, but only if it is used correctly.

    You are all right, but you forgot the main thing: OSB is prohibited for use in residential construction.

      OSB (in this case OSB3) has a formaldehyde content class of E1, which is lower than just boards or sawdust. This is for the attention of some "especially smart" people. Nobody prohibited the OSB supplied by Krono and others. This is nonsense. Further, Penoplex walled up in a screed, or not walled up, but lying freely, as in a post, vibrates in exactly the same way, and there is no difference, because concrete is not a sealing compound, which prevents the movement of vapors. Gentlemen! You are somehow not very technically literate, writing all sorts of figb. By the way, about the birds. Penopex, like polystyrene foam, is a vapor barrier, and if it is placed correctly on a wooden surface, nothing will rot. Here the ventilation of the space between the penoplex and the wooden floor is not fully thought out. Just the foam on which it is all glued will already provide a gap between the floor and the plex, but you need to apply it correctly. And everything will be alright. This floor will outlive everyone who wrote comments combined.

    fire safety is a controversial issue, and it’s time to learn chemistry, polystyrene releases exactly what wood does when burning, but what will eventually rot is 99% likely...

      thank you, teach yourself chemistry, expanded polystyrene is a derivative of styrene, read it on Wikipedia, styrene is a poison. And the combustion products of polystyrene kill even worse.
