Kids Seed Growing Kits

The gardening process is strengthened by Kids Seed Growing Kits and the great capacity of heat storage of the existing water in the plants and in the substrate. The same applies to the protection against wind on the surface of the roof, which prevents the exchange of heat by convection and the shade produced by vegetation.

These characteristics allow to achieve beneficial situations both in summer (with lower temperatures compared to other types of construction solutions) and in winter (with higher temperatures).

In short, what we get with a vegetation cover is a constructive solution with a lower thermal transmittance than in the case of conventional roofs, which translates into greater insulation and therefore energy savings compared to the use of roofs. air conditioning installations.

Different investigations in the last years have demonstrated the property that the vegetal covers have of improving the values of acoustic isolation with respect to a conventional cover. When comparing sound transmission losses in several decks with or without vegetation, reductions were obtained between 5-20 dB.

The vegetal finish (plants + substrate) reduces noise by absorption, producing a transformation of sound energy into movement and caloric energy; and the reflection, when creating a dispersion of the waves due to the irregular finish that this layer and Kids Seed Growing Kits presents.

In the case of absorption, the effect produced by the substrate is greater than that of the plants. For an angle of incidence of the vertical sound, the layer of plants obtains by means of the absorption only an insignificant diminution of the sound of high frequency, whereas the layer of earth, for a thickness of 12 cm, the reduction ascends approximately to 40 dB, and for a thickness of approximately 20 cm to 46 dB.

Measurements on a flat roof garden of a hospital showed that, in the facades located in the vicinity, as a result of absorption and reflection, traffic noise dropped around 2-3 dB. The duration of the waterproof sheets, regardless of the traditional cover layer that has the cover is limited, since it has to withstand the inclemencies of time, temperature changes and chemical decomposition processes.

With a vegetable finish the high temperature changes that must be reduced would be reduced and therefore the movements due to dilations and contractions would be reduced. On the other hand, the substrate protects the sheet from ultraviolet rays and from possible biological attacks.
