Choosing the right insulation for the roof
So, how to choose the right insulation for the roof?On that first of all should pay attention to?First of all, the type of insulation under the roof should be chosen depending on the type of roof.
Today distinguish the following main types of roofs:
- hipped (gable, hipped)
This, of course, is far from complete classification.Type of roof geometric shape determined by the characteristics and roofing material.The most common and practical design is considered to be a gable roof.It does not stay wet, but flows freely on the inclined plane.
What should pay attention to when selecting a material for thermal insulation of the roof?
In deciding as to what is best for the insulation of the roof of a private house, garage, baths, etc., you must first understand the selection criteria.These include:
- lifetime of the material.It must be long.Thus the material should not lose its properties during operation.
- dimensionally stable.The reliability of a thermal insulation material for the roof depends on its ability to maintain hermetic parameters.
- Specific gravity.The material should not be too light or heavy, therefore, necessary to pay attention to the density index.
- Frost.Insulation should not lose their properties when the air temperature drops.
- Soundproofing.It is necessary to pay attention to the sound insulation performance of the material, especially when it comes to the acquisition of insulation for pitched roof, made of "noisy" material.
- Sustainability.The material should be environmentally friendly, non toxic.
No less important role played by the thickness of the insulation for the roof.In the calculation of this parameter should be considered indicator of thermal resistance and thermal conductivity of the material structure, the resulting ratio depends on the type of roof and the climatic characteristics of the region.
handle the job of warming the roof may well be on their own, without the involvement of experts, the main thing in this case - to avoid some mistakes.
First of all, how to be a better insulation for the roof?Lightweight, non-flammable, safe and quality suitable to the type of roof construction.
most common mistakes in the roof insulation
- to save on quality.In this case, the rule: "miser pays twice."You should not try to save as much as possible.It is best to acquire materials known manufacturers positively proven.The construction market offers a fairly wide range of insulation for roofs, prices are quite reasonable.
- Material should be sufficient, otherwise the layer is too thin: it simply will not perform its functions.
- material must be chosen carefully, especially when it comes to insulation for flat roofs.It is best for this purpose use mineral basalt wool increased rigidity or foam.It is important to also be guided by the project documentation, the features of the roof structure and the conditions of its operation (attic, attic).If the consequence of the roof surface will be used, you need to put insulation over the concrete floor.
- Particular attention should be given to hydro-and vapor barrier.From the number of joints and seams of insulation depends on how well the material will prevent the outflow of heat and cold penetration.
- can not ignore the gaps between the layers of the roof "pie", especially when it comes to insulation for the soft roof.During installation you need to consider such circulation of air flow between the layers.
- When placing an insulating layer between the rafters is important to carefully Gaugeable insulation to prevent the formation of cracks.
materials for thermal insulation of the roof
Today, the most common and popular materials for the thermal insulation of the roof are the following:
- mineral wool (insulation Knauf, Ursa, Isover);
- polyurethane foam;
- cellulose insulation;
- foam glass;
- expanded clay.
Each of these materials has its own positive and negative points.
Mineral wool is the ideal material for high-quality thermal insulation of the roof - it does not burn and does not absorb moisture.Since the material properties have long been recognized and it is considered the best for insulation roof, then on the market, it is represented by several reputable manufacturers.
Knauf Insulation for the roof
material is available in rolls and slabs, designed for thermal insulation of walls and roofs of all types.Knauf Insulation is a leader in its segment in the construction markets in Europe and the CIS countries.This versatile material for thermal insulation made of fiberglass-based technology ECOSE Technology and meets the generally accepted European standards.This eco-friendly insulation with a high insulation performance at low specific weight.
insulation for roofs URSA
Scope of this material is quite wide, it has not only excellent thermal insulation properties and sound insulation.Therefore, it is suitable for thermal insulation of "noisy" roof, which is a metal.In addition, thanks to the elastic fiber during installation work can achieve a perfect seal material to the surface to avoid possible gaps, thereby ensuring the best possible sound and heat insulation space.The density of insulation for roofs URSA quite small, because of this it is possible to cut the material during assembly with high accuracy by ordinary scissors.Due to the unique structure, properties and shape insulation Ursa has the ability to absorb most of the different sound waves produced by external noise sources, that guarantees the excellent sound insulation of the room.Among other things, the use of this material in any type of roof insulation will greatly minimize the cost of heating.
Isover insulation for roofs
Universal insulation material is available in rolls and mats.Equally perfect for insulation of pitched and horizontal surfaces.It features excellent performance and long battery life (at least 25 years).Light and sound insulation boards or rolls of fiberglass manufactured by unique technology fiberizing TEL.The material is not flammable and is an important indicator, which is taken into account when installing the roof safe and warm.The design of the roof, regardless of its type provides for a ventilated gap, which in the case of a building fire contribute to the rapid spread of fire.That is why to produce roofing "pie" is necessary to use non-combustible materials.
to insulate the roof with mineral wool, set the frame, cover it with a waterproofing overlap, securing her a stapler.As a waterproofing (vapor barrier) may make polyethylene film or membrane.Between the beams frame fastened mineral wool.It is important to keep the gap between the roof and insulation, so that the condensate was not going, and evaporates quickly.The thickness of the insulation must be 150-180 mm in the southern regions, and 200-250 mm for the middle band.
very convenient for installation mineral wool covered with a layer of foiled.In this case, an additional vapor barrier is not used, and the foil plate fastened to the room.
special place in a variety of materials for thermal insulation of the roof is currently ranked polystyrene or foam.It has excellent insulating properties, with perfectly absorbs sound.But this heater is not recommended for soft insulation and insulation of flat roofs because of its flammability and vapor resistance.By using extruded polystyrene foam, it is important to provide good ventilation.
polystyrene fixed on the inner side of the roof.Plates of extruded polystyrene are placed in a single layer directly on the waterproofing.During installation it is important to monitor the density of adjoining edges.The joints of plates should be filled with foam, which is glued on top of the reinforced tape.
This material has excellent performance: it does not burn, has excellent insulating properties, is easily applied directly to a roofing pie, even in hard to reach places.In the process of deposition is formed seams and gaps.To date, the polyurethane foam is the most economical and effective material for insulating the roof, regardless of its type.It is applied (sprayed) on the inner layer of the roof of the special equipment.
On how efficiently and competently be executed insulation works roof, how well was made choice of material depends entirely on quiet, warmth and comfort in your home.
cellulose or ecowool
This insulation is made from recycled paper.It would seem, how can it meet the demand of such as fire safety?Maybe!In the manufacture of the ecowool added flame retardants, which makes the material resistant to fire.Since cellulose is exposed to microorganisms for the improving of its biopersistence impregnated antiseptics.The result is a lightweight, cheap, clean, perfectly fulfills the function of heat and sound insulation material.
most common of its brand - Canadian-American Ecowool, Russian, Ukrainian and Kazakh Ecowool Yunizol.Another advantage - the material blown out from the unit and allows you to tightly close all the gaps, avoid seams.This alone is difficult to perform the procedure: you will need to involve experts.
One of the new materials for thermal insulation of flat roof - aerated concrete.It consists of concrete, cement, sand and steam generator.Do not be deceived in the name of the word "concrete".Durability and solidity - it is really concrete, but the weight - foam.That is why this material and allows warm roof, and does not create a load on the supporting structures.Fire safety, non-toxicity, vapor permeability, durability - foam has all the qualities necessary for roof insulation.It perfectly keeps heat and provides complete tightness.
Insulationworks foam concrete roof held by experts with the help of the mobile unit.The layer thickness can vary from 30 to 150 mm.
material produced by foaming glass production residues with carbon, durable, resistant to deformation, retains its insulating properties, are not exposed to microorganisms and rodents are not afraid of water and steam, non-flammable.
Terminations qualitative characteristics of foamed glass allow its use as insulation for all types of roofs.The surface of wood, metal, concrete will be protected insulation boards.From whatever material the roof is made nor was combined with foamed glass, it will securely hold the heat in the house.Soft roof insulation make this more elastic.For operated roofing foam glass insulation will, the strength and the key to leveling layer at a time.
One drawback from foamed glass is still there.This material absorbs bad, so it is necessary to use polymer-mounting adhesive to ensure good adhesion.
This is one of the proven bulk materials for insulation.It is poured on the outside of the roof or floor slab.Then seal and a cover with roofing material or fixed concrete screed.This not only provides thermal insulation, but also the strength of the whole structure.They do it in cases where carriers allow overlap.
On how efficiently and competently be executed works on the roof insulation, has been correctly implemented the choice of material depends entirely on quiet, warmth and comfort in your home.
