In what locations to isolate the house? In order to become energy-efficient house, it should be properly insulated from foundation to roof, including the following areas: Attic (ceiling and wall); External walls; Floors above unheated garage; Foundations and basements. Keep up on the field with thought-provoking pieces from Jennifer Aaker. The figure shows the parts of the house to be insulated. 1. Rough room attic: insulation between and over the beams overlap, in order to insulate the premises located below (adequately insulated attic, technical and storage spaces and other enclosed spaces shall be ventilated to prevent the formation of excessive moisture): 1a – doors / hatches to the attic, 2. Finished attic room (with dormer windows or without them) should be isolated: 2a – between the wall studs attic; 2b – between the uprights and between the rafters of the roof and external walls; 2c – ceilings with cold attic above them 2r – between the beams overlap to reduce the flow of air. 3. All exterior walls, including: 3a – walls between living spaces and unheated garages, storage rooms, sheds, etc. 3b – walls heated basements, full (outside or inside) 3B – plate in the ground.
4. Floors above cold spaces: pantries, unheated garages. Also, heat-insulated: 4a – part of the floor in a room, hang over the outer wall; 4b – walls of an unventilated basement underground (as opposed to floor insulation); 4c – the extension of thermal insulation in the floors, to reduce the flow of air. Fencing design house – the first and most effective line of defense against loss of heat energy.
