roof insulation - an important stage in the construction of their own home.These works should be carried out efficiently and in good faith.From this it depends on how warm and dry will be in the house when outside the window is damp, cold and uncomfortable.
Modern building supermarkets and markets offer a huge variety of different materials for thermal insulation of roofs: mineral wool, fiberglass, basalt slabs, polyurethane foam and many other materials.But invariably the leading position still holds polystyrene, or, as it is called in the old people - in foam plates.The most suitable for roof insulation brand - PSB-S-PSB-25 and C-35.

What good is this st
- Durability material is characterized by increased levels of resistance to compression and tension.
- small proportion of it can be used for thermal insulation, even dilapidated structures, unable to withstand the weight of a heavier material.
- Durability: material withstands temperature extremes, resistant to mechanical damage and abrasion.
- Moisture resistance: completely foam does not absorb moisture, therefore, the material is not subject to deformation under its influence.
- to fire: the material is not prone to spontaneous combustion.It is best to choose a roofing insulation material group G1.
- Ease of installation: the work on the roof insulation foam will be the power of even inexperienced person.
- durable material: the service life of the heater - from 25 to 80 years.
Relatively recently appeared on the shelves of a liquid foam.This material has the same characteristics as in the foam slabs, but radically different way of drawing: Penoizol sprayed on the surface by means of a special installation.Thus, a continuous seamless surface is formed insulation layer.The only drawback of this method is the need for additional fixation mounting surface by thin sheets of foam or ordinary plasterboard.
Determine the amount of material
Before starting work on the roof insulation foam inside need to calculate the amount of material required.For warming of a mansard roof to calculate the optimal amount is sufficient is not difficult - you just need to measure the area of the roof, the spacing between the rafters and determine the size of the foam plates.However, experts recommend to get the material with a small margin (6-8 plates), as in the process of cutting itself may be a risk of deformation or breakage of the plate.
Warming mansard roof foam - accessories and supplies
to work you need the following materials and tools:
- anti-condensate vapor barrier film;
- wooden bars;
- a sharp knife;
- construction stapler.
end result depends entirely on how well and faithfully to be made the main stage.
roof insulation - based stages:
- deck waterproofing and vapor barrier film;
- installation of insulation;
surface preparation, waterproofing and vapor barrier
surface on which the foam will be laid must be clean and dry.
Styrofoam copes with waterproofing.But in order to extend the life of the foam, vapor barrier stack is required.
Please note that between the film and crate must be sure to leave a gap of at least 2 cm. If you do not, on the inner side of the insulation will continue to accumulate condensation that can cause the process of rotting rafters, odor, mold, etc..
In some cases laid condensed water vapor barrier film: overlapping directly on the rafters.They do this in cases where the width of the rafters makes it impossible to leave a gap between the polystyrene and wooden base.When it comes to the already finished structure - quite acceptable variant of the anti-condensate film fastening to the rafters through the wooden slats and nails.Also, for these purposes, it is possible to use a special construction stapler.Installing insulation
most common ways of attaching EPS boards:
- pasting (frost-resistant facade adhesives, liquid nails, mastics for gluing tiles to the ceiling, the time-mounted);
- mechanical fixing (nails, umbrellas, anchors, wooden slats);
- investment in the crate.
Sometimes fastening methods are combined.For example, investing in the crate foam, and further fixed with nails, umbrellas.Once the hardware is called the anchor for the foam termogolovoy.
often combine foam bonding and fastening it with screws.Gluing foam may be a brick, drywall, plywood, concrete, iron.
Foam mansard roof
After everything vapor barrier is the time to start the installation of insulation - foam sheets.Traditionally performed on the mansard roof rafter frame, between the rafters and boards of foam should be placed.In choosing such preference should be given to the plates, the size of which is equal to the width of the pitch between the rafters.But modern materials allow no gaps to insulate roofs with wide steps up to 2 m.
Polystyrene insulation boards must be placed between the rafters on top of them or crate.To heater kept more firmly and securely, experts recommend using both glue and dowels.In the process, may form between the rafters and boards of foam gaps and crevices.They must be carefully repaired by a common foam (it is possible to use any kind of sealant).
After all these steps, you can finish the outer surface - if you plan to equip the attic.The best option with the least labor and cost is a surface finish of gypsum boards, which are attached to the rafters with dowels.Further, it is possible to paint or wallpaper paste over the surface.
foam on a flat roof
fairly common way of polystyrene foam insulation and flat roofs.The surface is cleaned, coated with waterproof tape.Expanded polystyrene can be laid on a flat roof freely mounted cold and hot, nailed.
is important to lay the plate close to each other.
Styrofoam often participates in creating roofing "pie»:
If polystyrene is placed on a flat roof, it combined with a geotextile layer upon layer of gravel is poured fraction 16/32 thickness of at least 5sm.Takoy type of roof is increasingly used in modern urban planning.This makes it possible to equip a rooftop recreation area, lawns and even parking.
third variant the insulation cake: steam, Styrofoam plates, a layer of expanded clay, fiber reinforced cement-sand screed thickness of 30-40 cm.
using the above technologies can be equipped on the roofs of houses here are the oases.This is called inversion roofing.For its care polystyrene - material №1.
How to insulate the roof foam while avoiding common mistakes?
Installation of insulation made wrong in the near future will have an unpleasant consequences.Leaks that are formed as a result of poor quality of the work performed, not only violate the aesthetic picture, but also contribute to the process of rotting rafters.
Let's look at the basic errors, often permitted during installation:
- formation of depressions and cavities on the surface of the insulation.This can lead to the formation of cold bridges.During installation of insulation is necessary to avoid occurrence of such defects;
- improperly selected insulation plate width also leads to a violation of integrity with all its consequences;
- use cellophane tape instead of the anti-condensate vapor barrier - perhaps the most common mistake that can cause many ills and troubles.
To the house was always warm, dry and comfortable do not neglect the rules and standards in the process of mounting a heater.All work must be performed strictly in accordance with the generally accepted canons.Also, special attention should be paid to the quality of the materials used.
Many owners of private houses are wondering as to whether it is possible to insulate the roof foam.You can, of course.Material is not harmful to health, and also distinguishes itself with its performance and relatively reasonable cost.But he is sensitive to resins and oil paints, to be operated at -50 ... + 75 degrees, it provides for the installation of gaps that need to be further processed.
Comparing with other kinds of expanded polystyrene insulation (mineral wool, penoizol, polyurethane foam), to wrap the foam - the best insulation for the roof, it is impossible.But in some cases it is irreplaceable and one of them - the inversion of the roof arrangement.
