Arrangement of inhabited space on site of attic-floor room has stopped being unusual occurrence long ago. More and more owners of houses are interested in how it is correct to make repairs that life “under roof” was not less comfortable, than in the house. Let’s consider how to make warming of penthouse if it is already roofed what materials best of all will be suitable for this purpose and to what nuances it is worth paying attention.
Warming of penthouse from within if it is already roofed: preparation of the room
The penthouse is the not just made habitable attic. There are some norms which distinguish these two rooms from each other. First of all, the roof of penthouse shall have bias. Besides, floor-to-ceiling height established by norm has to be not less than 2.5 m.
Being guided by attractive exterior, many make the decision on arrangement of penthouse.
But in reality it is necessary to face some nuances which it is desirable to study prior to work:
- materials which were used for construction of penthouse directly define further heatlosses in this room. Therefore it is worth approaching their choice very responsibly;
- also correctly picked up engineering decisions which allow to provide all necessary communications on upper floor have not less impact;
- essential role is played by roof form. It can be lean-to, twin or broken;
- to hide roof supporters, it is necessary to show imagination;
- the penthouse can be located not only in the territory of the house, but also to go beyond its limits, leaning on columns.
Each of these aspects has the impact on approach which will be required for high-quality warming of roof. But the leading role nevertheless belongs to two parent materials – heat insulator and the hydroinsulator. On the one hand, the space under roof is in the coldest zone of the building. With another – strong difference between temperature inside also it becomes outside frequent the reason of emergence of condensate which it is destructive influences materials.
The best materials for warming of penthouse the hands
For internal warming of penthouse there is set of suitable options. But the choice needs to be made proceeding from features of the region of residence and also construction features of specific roof with which it is necessary to work. Let’s consider what options exist today and what features are characteristic of them.
Warming of penthouse polyfoam: pluses and minuses of material
Polyfoam – one of the most known heaters which occupies the niche among inexpensive thermal insulation materials.
Its price is really much lower, than at many others, but this its not only advantage:
- polyfoam does not absorb moisture at all. If previously to process material the impregnation which is specially intended for this purpose, then water will just flow down on surface down;
- small weight – one more advantage which significantly facilitates transportation and mounting and also reduces load of roof;
- heat conductivity of polyfoam is very small so it copes with the direct functions more than fully;
- polyfoam it is easy to cut and fix. It allows to work without problems with it even on condition of lack of any experience.
Interestingly! At cost this way can be compared unless to warming of ceiling haydite though now this method is used more and more seldom.
On the basis of these characteristics it is possible to draw conclusion that polyfoam – almost sure bet when it is about warming of penthouse from within.
But warming of walls polyfoam from within also has shortcomings, and sometimes they are far more essential than advantages:
- the vapor permeability of polyfoam is at very low level. As a result indoors often happens stuffy and hot. Also it leads to increase in humidity that becomes the reason of development of fungi and mold on wooden roof units;
- despite the artificial origin, this material often is exposed to damages from rodents;
- over time wood has property to take seat that leads to formation of slots between polyfoam elements. It is impossible to correct it, and the only solution of problem – full replacement of thermal insulation material.
Many consider that it is more listed shortcomings, than advantages and warming of penthouse polyfoam is not justified. But it is necessary to recognize that it is one of the most budgetary options which brings minimum of trouble, and at respect for technology of mounting, can quite become alternative to more expensive decisions.
Warming of penthouse expanded polystyrene: advantages, shortcomings and features
Extruded polystyrene foam is very similar to polyfoam. Their technical characteristics are almost identical, except for one essential aspect – technology of mounting. If polyfoam needs to be laid between rafters, then expanded polystyrene is put atop that excludes risk of emergence of slots and gaps.
Helpful advice! Some producers offer buyers of plate with step joints that allows to make places of connections stronger and reliable. Such fixing of elements among themselves – ideal option for warming of roof of penthouse.
Among other advantages of warming of roof expanded polystyrene it should be noted its small weight which is perfectly combined with high strength and resistance to external influences. Besides, the operational term of this material is quite big, on condition of respect for all technology of warming of penthouse penoplex.
Expanded polystyrene is not inclined to processes of rotting or decomposition that is also important, in case of work on roof. Over it any finishing covering which will give attractive exterior and will provide additional protection can be put.
It is independently simple to work with expanded polystyrene: various glue mixes and mastics are suitable for its fixing. And in certain cases use even the construction stapler. So for mounting there is no need to get any expensive additional elements.
But behind all these positive characteristics it is impossible to forget also about the only thing, but quite serious lack of warming by expanded polystyrene from within walls and roof – material has the increased combustibility level. It means need of more careful and thought-over leading of all communications for owners, in particular, of electricity.
Of course, producers try to minimize this shortcoming, but today with confidence it is possible to tell that this question remains open, and each owner who has made choice for warming of walls from within penoplex is obliged to take care of the safety.
Interestingly! Not accidentally this material is the most often than others choose for warming of balcony. Expanded polystyrene has very low heat conductivity, and at the same time on balcony it practically should not contact to electricity.
Warming of penthouse from within mineral wool: worthy alternative to penoplex
Mineral wool – one more thermal insulation material which is used everywhere and is widely known thanks to the characteristics. It has received the name because of the fibrous structure similar to medical cotton wool. It is possible to buy it in rolls that does transportation and mounting it is even more convenient.
Low heat conductivity is perfectly combined with ability not to absorb moisture. Though if it also occurs, material quickly dries, without losing the exterior and technical characteristics.
Mineral wool belongs to the category of environmentally friendly and safe materials that it becomes noticeable even if the upper part of roof will be covered with metal tile which is inclined to strong heating under the influence of sunshine. Besides, mineral wool serves also as sound-absorbing barrier, and unlike polyfoam, is not of interest to rodents and different insects at all.
Warming of roof needs to be done by mineral wool from within taking into account the fact that it is quite elastic material even despite the soft fibrous structure. It is quite capable to keep between rafters on condition of high-quality fixing.
Helpful advice! In the course of cutting of mineral wool for laying of sheets between rafters, it is necessary to leave stock about 2 cm. It will allow them to keep and not to drop out even on condition of lack of additional elements of fastening.
Warming of roof from within glassy: whether it is worth using this material
On the characteristics glass wool is similar to mineral wool, but in this case fibers of which material consists, differ in bigger length that in general increases elasticity of material. Slightly higher both strength indices and sound-proof abilities. And here at contact with moisture glass wool concedes to mineral wool, absorbing bigger amount of water.
Use of glass wool for warming of premises does not lead to any negative effects for health of living. No toxic substances in the course of production are used. Besides, glass wool is characterized by low indicator of combustibility.
In the course of work with material observance of safety instructions is required to avoid hit of fibers of glass wool in air. Its small particles is capable to cause irritation mucous, and therefore use of respirator and safety glasses is indispensable condition.
Helpful advice! Fibers of glass wool can sometimes cause irritation of skin therefore in the course of work with it recommend to put on the closed clothes and even gloves.
Warming of roof of penthouse from within the hands about use of stone cotton wool
Stone cotton wool — the most expensive option among similar materials. But at the same time it is the safest for human health and on reliability degree considerably exceeds all other options.
There are its several main advantages:
- coefficient of thermal conductivity at this material one of the lowest;
- stone cotton wool remains completely eco-friendly even when heating;
- the layer of this heat insulator is also excellent noise-absorbing barrier;
- level of vapor permeability is very high;
- material practically does not burn;
- no mechanical loadings are capable to deform stone cotton wool or to affect its characteristics;
- material differs in the long term of operation;
- it is possible to buy stone cotton wool in the form of plates which are easily cut on pieces of required length and fasten to ceiling surface.
Because of the high cost of stone cotton wool it is often tried to be replaced by means of mineral wool or glass wool. But it is impossible to call such replacement full as it affects quality of warming quite seriously. Many users claim that the price of material is quite justified, and on condition of respect for technology of mounting, it very quickly pays back the provoked expenses.
Besides, it is quite possible to carry out all works on warming of roof of penthouse by the hands from within. The video instruction can show work order, and the recommendations of specialists will allow to avoid widespread mistakes.
Warming of penthouse ecocotton wool – one of the most effective ways of fight against cold
Ecocotton wool – previously crushed material into which blow at first in slot and then by means of the same way, put layer between overlapping and rafters, using the device which is specially intended for this purpose. It is the expensive procedure, but it allows to exclude completely all risks of emergence of drafts and to provide the most effective warming.
Ecocotton wool for 80% consists of completely natural material – paper which properties are very similar to those which are characteristic of wood. At the natural origin, ecocotton wool reduces the level of heatlosses not less effectively, than other materials.
One of components which is part of ecocotton wool – drill. On the characteristics it is anti-septic tank of natural origin that allows to provide to wooden elements of roof effective protection against formation of fungus and mold.
Apply ecocotton wool with thin layer, but at the same time it provides worthy level not only warm, but also noise isolations. Material keeps the characteristics even decades of use later. So not too low cost – the only lack of this material which quite comes true its excellent properties.
Warming of penthouse polyurethane foam: fundamentals of technology and feature of material
Frothed polyurethane foam is the most modern among all listed ways to warm penthouse. Its main difference in total absence of joints or gaps which can become source of cold air. Besides, the operational period of this material one of the longest, also makes up to 30 years.
Frothed polyurethane foam is not subject to shrinkage even if the wooden rooftop begins to be deformed gradually over time. Its strong structure completely excludes risk of absorption of moisture that allows to refuse need of mounting of additional vapor barrier layer.
But there are also aspects significantly complicating process of use of polyurethane foam as roof heater from the inside. First of all it concerns the procedure of drawing which requires the difficult and expensive equipment. Its purchase practically is never justified so usually it is leased.
Other aspect – difficult technology of drawing which provides availability of certain experience of work in this sphere and does not allow beginners to cope independently with objective qualitatively.
Helpful advice! Ideal option – to invite team of workers who will arrive with own equipment and in only several hours will make high-quality warming of penthouse of your house.
Warming of penthouse from within the hands with use of penofol
Penofol is some kind of frothed polyethylene – technology which occupies the niche among ways of modern warming of walls and houses. Along with high rates of sound insulation, It should be noted also the fact that penofol has qualitative covering from aluminum which can be applied on one or two parties.
Here some more arguments in favor of use of penofol for warming of penthouse:
- material does not pose any threat for human health or the environment surrounding it;
- the indicator of its heat conductivity is extremely low;
- the closed system of air bubbles characteristic of this material serves as excellent barrier to steam penetration.
This way also does not belong to cheap and demands for implementation of the essential financial investments. But, as practice shows, once is better to spend for quality material and by that to provide comfortable conditions of accommodation for many years ahead.
At all not rarity and combination of materials. The materials which are combined on characteristics can be used for warming together. For example, mineral wool and expanded polystyrene are perfectly combined among themselves. The first is stacked between rafters, and the second is had closer to the roof edge. Such combination will allow to achieve desirable effect and it is essential to save on acquisition of materials.
As it is possible to see from descriptions, each heater has the advantages and shortcomings. Question only in picking up the most suitable option which will satisfy to idea of compliance of the price and quality of material.
One of the most widespread mistakes which are made by owners – the rash choice for the cheapest option for warming of penthouse. Videos and articles can show positive aspects of this or that decision, but it is necessary to choose considering all nuances and characteristics. Attempts to save on thermal insulation material can lead to the fact that after a while operation, it is necessary to carry out repair works or even completely to replace all material.
Warming of penthouse from within the hands: work stages
Each of materials has the features of fastening and has to be used only according to the recommendations of the producer. But if to speak about the general order of work, then there are obligatory stages which are carried out practically always, regardless of the chosen material.
The first the layer of waterproofing material which has to protect heater from destructive influence of moisture gives all the best. The film is stacked with an overlap so that one layer found on another on 10-15 cm. Fix material by means of the construction stapler, and places of joints in addition glue with adhesive tape.
Then, if in it there is need, furring is created. For it it is possible to use wooden rails which width of 8-10 cm. It is necessary to fix them to rafters, having in parallel each other at distance of 50-60 cm. It is very important to carry out inspection of each element separately, using construction level. It will allow to prevent emergence of any defects of roof further.
On rafters or furring the heat insulator keeps within and fastens in the way suitable for it. For example, if the speech about use of any type of cotton wool which is on sale in the form of rolls, then material is cut on pieces of the necessary size to lay them between rafters. At the same time thickness of heater has to be such to correspond to width logs. Especially important if you have decided to make warming of walls mineral wool plus gypsum cardboard from within. In this case all free space has to be filled with heater.
Top layer of it “pie” — layer of vapor barrier material as which the polyethylene film, paper roof covering or roofing material can be used. As well as in case of waterproofing, the chosen material keeps within with an overlap. However, in this case it is better to carry out fastening by means of thin wooden rails, having them with step of 40-50 cm. All joints surely glue with adhesive tape.
Helpful advice! If you needed laying of several layers of thermal insulation material, between each of them it is required to lay vapor barrier film. Especially relevant it for cold regions.
As completion phase it is necessary only to take care of suitable finishing covering which can fasten to furring or in case of its absence, directly to bars. In attention it is worth accepting the weight of the used decorative panels as installation of the heaviest of them can demand preliminary mounting of framework from metal section.
The main mistakes made in the course of warming of penthouse
The end result of work which is run by the hands directly depends on that, the technology and all ordered rules is how precisely observed. Especially attentively it is worth treating the procedure of laying of waterproofing course as materials which are capable to absorb moisture already dry further that it becomes frequent the cold reason indoors.
Here several recommendations from specialists, using who it is possible to minimize negative effects:
- if the tilt angle of roof does not exceed 13 °, it will become the reason of delay of rainfall on surface. As result – emergence of rust and emergence of leakages. All this can negatively affect condition of heater so it is important to be convinced that the tilt angle is rather big before getting to work;
- mounting of thermal insulation material on walls and roof – there is more to come necessary works. It is necessary to take care also of warming of windows (on the Swedish technology). It is the for this purpose best of all to invite specialists for certain to avoid leakage. In particular if installation of windows under inclination is required;
- to provide to thermal insulation material airing and opportunity to dry up in case of soaking, it is desirable to leave gap about 2-3 cm between material and roof;
- categorically it is impossible to pass at least one of necessary layers of vapor barrier or waterproofing materials;
- if the thermal insulation material on thickness exceeds rafters, their height can be increased, having independently filled additional rails.
These simple recommendations can help with work process, significantly having increased quality of warming. However, if for any reason doubts and experience are able, it will be better to invite the specialist. Of course, it is necessary to pay for it, but in this case it is not necessary to remake everything twice.
Warming of pediment of penthouse from within – not the most difficult task which the owner of the house can face. Quite often on upper floor owners wish to arrange balcony which technology of warming also has the features.
As well as for walls, for warming of ceiling on balcony the most various materials though, It should be noted that here the technology of warming of loggias which was not mentioned before quite often applies can be used.
