🔨 warm floor in the house on screw piles: reducing heat loss

click fraud protection

Using Ground Screws - a relatively new technology that has proved to be excellent in areas with difficult ground conditions. Nuance construction of the house - the absence of the cap, basement and foundation in the traditional sense of the word. A very important task in this case is a reliable insulation of floors of the first floor. This review HouseChief.ru edition we describe in detail about the warming of technology through advanced materialsThat will forever remove the cold floor problem.

Design features homes on screw piles

We can not say that screw piles - so-new idea. The practice of using them goes back a half century, with the development of technology linked to military needs. On screw piles put the pillars of strategic and pre-fabricated objects: bridges, power lines, lighthouses. They can be installed even on frozen and soft soil.

But the use of a screw pile foundation for housing construction did not begin so long ago, it is true. And while the technology is still under further development and improvement. But now, with the development of frame constructionIt has become extremely popular. The reason for this take-off is simple: pile foundation is versatile and suitable for almost any soil. An added bonus for those who chose a serious savings in labor and materials, because in this case there is no need to dig deep trenches and spend money on reinforcement and concreting.

All work can be done without the use of special equipment, manually. The process of installation of the foundation takes a maximum of one or two days, after which you can immediately begin to build the house frame

Pile foundations demonstrated their peculiar stability in seismic areas. Builders say high margin of safety this foundation.

How to choose a heater for warming the house floors on screw piles

The construction features for home screw piles is that under the floor of the first floor is a space of 0.6 m height, called ventilated underground. How to protect the floor from the cold in this case?

It is necessary to design high-quality insulation overlap of ventilated underground.

🔨 When a problem arises squarely: how to keep warm in the house on screw piles

For this purpose, the lower reel floor joists are placed between a heat insulating material, followed by a vapor barrier and the subfloor.

How to choose insulation for floorsSo it most effectively perform its mission? The most popular are three options: Mineral wool, polystyrene and extruded polystyrene.

Styrofoam

The foam is attractive for its price, and many prefer to use for them. Laying is simple, but in order to serve a floor for a long time, you can not buy a cheap foam because his strength is not enough to withstand a distributed load on the subfloor. Another deterrent to the use of this material is its water absorption. It reaches 4%, which can subsequently lead to significant deterioration of heat insulating properties. Adding all these factors, we see that for use in the genital structures we need foam with high density to be further protected from moisture, and it will be dear design.

Mineral wool

Stone or glass - another popular insulation material in construction. Elastic and soft pieces of mineral wool is good fit in the space between joists.

Despite its deformability mineral wool is sufficiently durable material under mechanical stress

The main drawback of wool is that it absorbs moisture, and after such saturation loses its insulating properties. If you opted for this heater, be sure to pay special attention waterproofing. And keep in mind: to fill a floor under tiles Mineral wool is not suitable.

PENOPLEX®

PENOPLEX® It differs from the foam expansion procedure. The foam is generated by the steaming vapor polystyrene granules that increase in temperature when their volume increases and fills the factory shape. extruded polystyrene It is obtained by extrusion - by mixing polystyrene beads and blowing agent at high temperature and pressure and the subsequent extrusion of special devices - extruder.

Due to such a complex technology product acquires special properties: increased strength, minimum thermal conductivity and virtually zero capacity to hygroscopicity.

If we talk about the practice of floor insulation, there PENOPLEX® no equal. This is confirmed by numerous reviews.

Benefits PENOPLEX® insulation in the floor

PENOPLEX® It has excellent thermal and mechanical characteristics, which certainly set it apart other materials and put it on one of the first places among the best of modern insulating materials:

  1. Coefficient of thermal conductivity - one of the lowest among the popular thermal insulation materials, only 0.032 W / m · K.
  2. The coefficient of water vapor permeability - up to 0.008 mg / (m · h · Pa).
  3. Compressive strength - 0.15 MPa, which enables the material to withstand heavy loads.
  4. Safety foam polystyrene for man scientifically proven. It does not contain toxic to humans of chemicals.
  5. Long service life - a heater layer capable not lose its properties at least half a century.
  6. PENOPLEX® and can preferably be laid on top of a layer of intrinsically subfloor that It eliminates the probability of formation of cold bridges and heat loss through the beam.
  7. Exceptional ease of installation. PENOPLEX® easy to cut the usual knifeFastened by glue. It can work with any temperature air.
Biostability Penoplex gives confidence that it will not become breeding ground for bacteria and fungi. He's not attractive to rodents and insects

Warming PENOPLEX floors®: Installation of foundations

Warming of the floor of the first floor in the house on screw piles has its own characteristics. Originally installed on screw piles headroom joists. They are located at a certain height from the ground. In order to lay the insulation need basis. For this is on top of the beams.

The next stage - laying the insulation on the vapor barrier, as which are generally used polyethylene film good. Vapor barrier will protect from moisture already inside the house. Further plank subfloor (variants are possible as a wooden board, and devices cement-sand screed) And on it - topcoat - linoleum, laminate, parquet or tiles (Depending on the design of the subfloor).

Important! Directly on PENOPLEX® lay laminate flooring is not necessary, will break the locks.

In more detail the process floor insulation on ventilated underground It is described on the website PENOPLEX®.

As you can see, the installation PENOPLEX® It is very simple, and it is quite possible to carry out his own, and it gives great savings. And even if for some reason the original floors were not insulated properly, you can do it and after, an example of such work in this video:

Results and recommendations

Of all types of thermal insulation materials for thermal insulation of floors PENOPLEX® - apart from the competition. It is characterized by strength, resilience and security. If your house is on screw piles, PENOPLEX® It will not prevent the drying of the beams, leaving them open.

Extruded penoplistirol has excellent insulating properties at relatively low thickness sheets and lightweight
