importance continuity thermal insulation layer insulation home

importance continuity thermal insulation layer insulation home – From warm House , it should be remembered that the maximum energy saving effect is achieved only in the case of full compliance with the principle of a closed loop heat , eliminating the possibility of even small non-insulated areas.
In this regard, mineral wool , as we have chosen to home insulation material must be placed fairly tightly , trying to avoid the appearance of gaps and cracks between adjacent boards .

Immediately need in this context to draw attention to the following areas:
wall joints with beams ;
joints of the walls with a roof ;
overlap joints with roof ;
window slopes ;
place under the window sills ;
balcony or loggia.

All of the above areas are very unreliable in terms of dense packing mineral wool insulation because of its complex geometry .

However, not only loose fit insulation material is the cause of cold bridges . Insufficient thickness of the layer of insulating material may also contribute to the appearance of heat leakage .

Since the exterior walls and roof of the house is separated from the interior of the home negative weathering environment , in fact they protect indoor climate at home from outside influence . For example , the roof at home can experience temperature fluctuations amplitude of 100 degrees Celsius for the season: from -30 ° C in winter to +70 ° C in summer. Material insulation of external walls and roof and is designed to smooth out these fluctuations in temperature , and insufficient insulation layer simply can not cope with these impacts and will skip the heat flow out into the winter and summer.

Mineral wool insulation thickness must be chosen , taking into account the temperature zone in which the house is located , as well as on the type of the enclosing structure . For example , the thickness of mineral wool insulation for pitched roofs shall be not less than 150 mm , and even better – 200 mm. Thickness of the layer of stone wool for insulation of facades – from 60 to 80 mm.
One last point about this property mineral wool insulation boards as stiffness .

Use of mineral wool panels of insufficient rigidity (for external wall insulation need to use n- mark 150 or more – n- 175 , n- 200) and an incorrect choice of the geometric dimensions can lead to creep and sag the heat insulation layer , which occur due to the discontinuities of insulating contour and form cold bridges . To avoid this problem it is necessary to lay insulation boards in at least two layers overlap with mandatory joints.
