Building wooden houses again gaining popularity because many people like the air with their unique special aroma of wood.If for some reason the building during construction is not insulated, it is certainly necessary to fix it.To save the house of wood heat insulation should be done on all surfaces: floors, walls, ceiling and roof.In this article we will talk about how the warming of the wooden roof with his hands, using the most common methods.

Necessity insulation wooden roof
timber itself is an excellent insulating material.And the operation of a residential building to use these properties and try the natural convection of air in the room is not broken.Due to the thermal insulation of the roof of th
If properly perform insulation wooden roof and prevent the movement of air currents, there is a dampness in the rafters, joists and ceiling appear fungus and other unpleasant consequences.
To avoid this, you must carefully consider the choice of insulating material, taking into account the fact that the roof of wooden and brick houses are very different among themselves.Therefore, materials used for thermal insulation of brick buildings are not suitable for wooden houses.
should use special insulation materials for thermal insulation of wooden roofs, which have a long period of operation, resistance to moisture and different loads, the ability to prevent the formation of cracks and deformation, there is no risk of shrinkage, as it leads to the emergence of cold bridges.
For many years the best insulation for wooden roofs believed straw.Today, there is a wider choice of materials for thermal insulation of roofs of wooden houses.Since houses of wood can easily ignite, made use of such materials, which are not subjected to fire, for example, fiberglass and mineral wool.
Features wooden roof insulation
If the house is newly built, it is impossible to carry out insulation until a shrinkage of the wooden structure.After the construction has to pass at least a year.At the same time you have to complete the finishing of the roof.Brothers for heat insulation work is possible only after removal of all defects that are the result of subsidence at home.
If a residential house for many years, it is necessary to heat insulation of the roof of a wooden house to approach more thoroughly.If the roof is leaking and subjected for a long time exposed to fluctuations in temperature and humidity may need major repairs or new slab.Carefully inspect all places, the integrity of which you have raised doubts, and check for wood rot.
But if the attic is used as an attic or storage room or in your area is too harsh winters, it is not enough just to warm wooden roof, you need to simultaneously isolate and roof and ceiling between the attic and living quarters.Required insulated ceiling and inside the house, and the attic floor.
Equipping wooden mansard roof, it is desirable to combine thermal insulation with special reflective film, which is made on the basis of aluminum.Coating reflects the composition of the party mounted outside.The main purpose of the film lies in the reflection of ultraviolet rays in the summer months when the Sun's activity, which should reduce the heating of the air in the attic.
Warming of the wooden roof with his hands
to perform work related to the insulation of the roof, do not necessarily have to be a qualified builder.It is enough to watch video on a wooden roof insulation and understand that it is impossible to save on heat insulating materials.
roof insulation mineral wool
Warming of the wooden roof with mineral wool is characterized by high efficiency and durability.Lightweight mineral wool defines the minimum mechanical load on the roof structure.Mineral wool is suitable for long-term use in the summer and good resistance to elevated temperatures, as opposed to foam.
If you plan to insulate the roof with mineral wool, it is desirable to use mats of mineral wool and not the web material, as they do not settle over time and better keep their shape.But when buying material in the mats can be easily Fit gaps between the rafters.The material can be cut and cut.
During the work it is necessary to strictly follow this scheme, a wooden roof with mineral wool insulation:
- first layer - waterproofing.If you are looking for the most affordable option, you should use the conventional waterproof film, which copes well with its tasks.But if the effect is important to you, it is better to buy superdiffuznuyu membrane.To her heater can be mounted back to back, without making additional ventilation crate.Her steam-capacity is much higher than that of ordinary waterproof.
- Insulation.The insulation material must be laid in two layers in the cavity formed roof rafters.Stack made a dense layer of 10-25 millimeters.Its thickness will depend on the climate in your area.Insulation must be laid so that between them the upper edge of the rafters remained ventilation gap, which serves for the removal of warm, humid air that enters the bottom.But it is necessary to make sure that the insulation material does not get out beyond the roof system.Mineral wool slabs, do not cover the cables and wires.
- Vapor.Over the insulating material is attached to the rafters vapor control sheet, which is required for detention saturated air that rises.To eliminate the ingress of moisture taken prokleivat all seams film special adhesive tape construction.Therefore, the insulation will be in the so-called moisture-proof "bags", but the ventilation gaps at the same time ensure the normal air from entering.Then the roofing can be laid.
expanded clay roof insulation
Keramzit called the most environmentally friendly of all the materials that are used for thermal insulation of roofs.Therefore, for the insulation of wooden roof it fits perfectly.Such insulation is considered to be durable, it does not shrink and do not spoil the rodents.If you lay the right material, the probability of formation of cold bridges are minimized.
Besides the cost of insulation wooden roof haydite acceptable: there is no need to invest large sums of money, you just need to buy a roofing rolls and plenty of expanded clay.
And the act is of such technology:
- To begin, close all the gaps, so as not to spill material.In this case, a special film is not suitable - it can not bear the load.Therefore it decided to lay on the slab roofing.This should be done on the surface of the walls overlap.
- Fill material.Do this carefully, because the properties of expanded clay under intense backfilling worse: many particles can break up, losing its insulating ability.
- Top may also cover the insulation roofing material, which simultaneously will act and waterproofing materials.
polystyrene Styrofoam is not the best insulation for residential houses made of wood, but if you have selected this material, you should pay attention to his group of flammability.The most optimal variant of the existing four groups is G1.Styrofoam with a marking illuminated solely in contact with the fire source.
polystyrene has a number of advantages: ease, the possibility of cutting it without special equipment, the ability to retain heat well even at high humidity, resistant to fungi and insect pests.
wooden roof insulated with polystyrene foam should be in the same way as when using mineral wool.The only thing: at the junction of the plates should be required to fill in the gap, as shown in the photo wooden roof insulation.This is done most conveniently by means of foam, because it can be evenly distributed around the hole without gaps.Additionally, this procedure does not take much time.
finalizing the insulation
If you are completely warmed wooden house and its roof, the ceiling should be sure to insulate because of the nature of wood as a material.Warm air in a wooden house, rising to the ceiling, with a will carry particles of moisture, which are deposited on the floors and ceiling and provoke a process of wood rot and mold.Thus, on the ceiling, you must install a heater with elements of waterproofing.Driving ceiling insulation in a wooden house with a pitched or flat roof and attic looks like:
- Airbag - space between the insulating material and a ceiling for the prevention of the formation of condensate.
- Insulation with fireproof insulated material.
- Vapor - membrane or film that prevents the penetration of moisture to the kappilyarnoy overlaps.
You can then proceed to the floor insulation in the attic, which is done as follows:
- Eliminate the gap between the beams and joists.You can them caulked oakum, jute or felt, or complete using the foam.
- Lay on the floor of the attic vapor barrier, on top of it - without gaps, place a layer of insulation.As insulation you can use foam or mineral wool.
- floor surface sprinkle stirrer or expanded clay, followed by a coupler.If you plan to use the attic, you can arrange wooden floor.
addition, for thermal insulation of a wooden roof, you can use Penoizol or liquid polyurethane foam, which is inexpensive and effective material.It is usually applied by spraying directly on the surface to warm.The whole procedure takes a minimum of time.Price wooden roof insulation penoizol low.There is no need to prepare further or remove the base.The work is completed with the achievement of the desired thickness.
