Quality housing is important that the house during the summer temperatures fluctuate sharply and does not overheat is. That the house well insulate heated serving trays any thermal insulation with comparable thermal resistance, works wonderfully in winter. In the summer, this is not enough.
In winter, the house heats and heating system can flexibly respond. If out "less cold" heats less. If it's cold greater prikúri more. Heating heated serving trays control is trying to keep the temperature at a constant temperature ever.
Assuming that we do not want the climate in the house and cooling, the situation will change in the summer. Inside the house we have thus a flexible system that responds to variations in temperature outdoors. During the day the temperature outside rises well over 30 degrees and night falls again ... Of course, this change should address, but I do not consider it to be healthy and not economical solution. Especially at normal wooden house or attic space, no accumulation masses may be the problem and the house may overheat.
Selecting appropriate materials in external structures through which the house trying to get warm. The timber and even brick houses lofts are songs structures represented mainly thermal insulation between the timbers. And the insulation are significant differences. Normally be judged according to the parameter λ thermal conductivity, the unit is W / (mK). It gives each manufacturer of thermal heated serving trays insulation as the main parameter. The lower the number, the better insulation in winter isolated.
For an idea gives an example: Expanded polystyrene (λ = 0.035-0.040 heated serving trays W / (m K)) Mineral wool (λ = 0.032 to 0.05 W / (m K)) Fibreboard insulation (λ = .038 to 0.05 W / (m K)) Hemp insulation (λ = 0.035 to 0.050 W / (m K)) Sheep wool (λ = about 0.04 W / (m K)) Cellulose insulation (λ = about 0.04 W / (m K))
Of the variables that are used in building physics, has the best explanatory power phase shift of the temperature oscillation. He refers to the time that passes the amplitude of the temperature oscillation from one side to the other structures. Thus describes the dynamic behavior of structures. This is the official definition ... and if you are not proficient in physics, this definition probably will not help.
So now I'm trying to explain "Polop". Imagine heated serving trays the morning sun shines on the wall, and it will be "roasted" all day. The wall is heated and transfers heat to the interior gradually. Once it gets this heat into the house, the house begins to overheat. Therefore, the later wall heat thus released in, the better. The ideal situation is that the heat takes this path structure heated serving trays as long as the end date. Then comes the evening air and the outdoors will schladzovať. Since heat always goes to cold, the flow turns in the wall and embankments will go out. The house is therefore not receive. This is a long phase shift.
For a better idea I present a selection of materials applicable to the attic. Specific heat capacity (c) density (ρ) Quantity of stored heat [J / kg.K] [kg / m 3] [J / m 3. A] Mineral wool (Isover Domo) 840 15 12 600 Sheep wool 1720 16 27 520 Polystyrene - EPS 150 S 1270 25 31 750 Hemp insulation (Hofatex CannaTherm) 1600 30 48 000 Cellulose insulation (Climatizer Plus) 2020 40 76 000 Fibreboard insulation (Hofatex Therm) 2000 150 300 000
My recommendation to the conclusion: When selecting insulation is often seen on the price. Consider at first sight, but also more expensive isolation because they offer further added value. If you consider, for example, cooling the house, and due to this insulation would not be necessary, the overall financial statement may be even more favorable.

I assume that in the near future, the results of unhealthy insulation used to for the last 2-5 years asserted only because prices are so known to fall out. Personally, I recognize only sheep wool, Hofatex, hemp insulation and boards krupina. This article has great substance and high professional level, suggesting Otom that Ing. Lehocký is really fantastic advice on how to build.
This article really spoke to me! I argue that sandwich construction heated serving trays using mineral waves have poor storage capability. People with these houses will gradually run ... The effect I called "burn out" - that is, that the heat radiation of the sun on the wall of the house wall heat accumulates to the point that it begins to glow inside the heat ... therefore again commend old earthen houses with clay walls, where in summer you can perfectly relax, a similar effect is achieved unburnt and burnt brick - these materials have very high thermal capacity. So this parameter is considered to be substantial. In conclusion, I wish to thank
