Exterior wall insulation area = the area of the outer boundary of the wall - the area of the door and window openings + side wall area (added to the outer edge of the insulation layer); exterior wall insulation area is about 0.5 - 0.6 times the total floor area.

Generally it is calculated according to the actual pasted area after completion. That is, the perimeter of the building multiplied by the total height, minus the door and window openings and balcony floor, air-conditioning panels occupied by the area of the number. If the balcony, balcony on both sides, the first floor of the balcony floor, floating windows on the lower board have to paste in addition to the line.

Note:

Polystyrene panels in the corners of the hole does not allow seams, seams from the corners ≥ 200, so as to avoid cracks in the hole in the finish.

Each row of polystyrene boards should be staggered seams, staggered length of 1/2 board length.

Other holes outside the door and window, refer to the door and window openings.

Other heat preservation and insulation area

1, heat preservation and insulation layer Should distinguish between different thermal insulation materials, unless otherwise specified, are based on the design of the actual thickness of the pavement in cubic meters.

2, the thickness of the thermal insulation layer is calculated according to the net thickness of thermal insulation materials (excluding cemented materials).

3, ground insulation layer according to the enclosure structure between the net area of the wall multiplied by the thickness of the design to cubic meters, without deducting the volume occupied by the columns, stacks.

4, wall insulation, exterior walls according to the center of the insulation layer, interior walls according to the net length of the insulation layer multiplied by the height of the size of the illustration and the thickness of the calculation in cubic meters, should be deducted from the volume accounted for by the refrigerated door openings and pipeline through the wall holes.

5, columns wrapped in heat insulation, according to the center line of the column shown in the center line of the heat insulation layer of the unfolding length multiplied by the size of the height and thickness of the illustration to calculate the cubic meter.
