The\nmore insulated the house is and the tighter its frame, the less\nenergy escapes through its walls, floor and roof. A house can be\ntight and still breathe. \n<\/p>\n\n\n\n
In\ndetached and semi-detached houses that have plenty of ceiling area\nrespective their volume, 8\u201318% of the heat escapes through the flat\nroof. This is why insulating the flat roof is often the best way to\nimprove the building frame\u2019s energy efficiency. In some cases, the\nthermal energy consumption of a detached house has reduced by half\nafter adding insulation. In apartment houses, 4\u20136% of thermal\nenergy escapes through the flat roof, and adding insulation is\nusually worth it only in connection with flat roof renovation for any\nother reason. If the house has a vacant attic where new insulation\ncan be blown on top of old insulation, adding insulation is usually\neconomical.<\/p>\n\n\n\n
In some cases, the thermal energy consumption of a detached house has reduced by half after adding insulation. <\/p><\/blockquote>\n\n\n\n
The\nbenefit of very thick insulation is very small, and excessive\ninsulation may increase the risk of dampness in the structures\nwithout the drying effect of heat loss. A rule of thumb limit for\ninsulation thickness in the flat roof is 500 mm. If insulation is\nadded, it should be the same or similar material as the original\ninsulation. For example, it is not recommendable to add mineral wool\non top of wood fibre insulation.<\/p>\n\n\n\n
In\ndetached houses, 13\u201319% of thermal energy escapes through the\nwalls, in semi-detached houses the amount is 12\u201315% and in\napartment houses 13\u201317%. Adding insulation to outer walls is quite\nexpensive, however, and should be done when renovating the facade for\nany other reason. Airtightness can be improved in skeletal wooden or\nlog houses by renewing the air-barrier materials. Draught will cause\na sense of cold. In a wooden house, insulation is supposed to thin\nout layer by layer outward. In addition, the window and door joints\nare prone to air leakage.<\/p>\n\n\n\n
In\ndetached houses, 7\u201310% of thermal energy escapes through the floor,\nin semi-detached houses the amount is 10\u201315%, and in apartment\nhouses 5\u20136%. A ventilated floor can be insulated below the\nstructure as long as its hygrothermal functionality and ventilation\nare ensured. \n<\/p>\n\n\n\n
Thermal imaging helps locate air leaks and heat loss in the building structure. Insulation should be designed by professionals to prevent moisture problems, for example.<\/p>\n\n\n\n
