How to calculate the area of external wall insulation, and how to calculate the external wall insula

1. Exterior wall insulation = area of the outer edge of the wall - side wall of the door and window openings (added to the outside of the insulation layer).

2. Exterior wall plastering = area of the outer edge of the wall - side wall of the door and window openings (without the outer edge of the insulation layer).

Exterior wall insulation area: about times the construction area. Generally, it is calculated according to the actual pasted area after completion.

That is, the perimeter of the building is multiplied by the total height, and the area occupied by the openings of doors and windows, the floor plate of the balcony and the air conditioning board is obtained. If the inside of the balcony, on both sides of the balcony, on the bottom surface of the balcony on the first floor, and on the upper and lower panels of the bay window, there is an additional addition.

a) The thermal insulation layer shall be distinguished from different thermal insulation materials, unless otherwise specified, according to the design thickness of the paving in cubic meters.

2) The thickness of the thermal insulation layer is calculated according to the net thickness of the thermal insulation material (excluding cementitious materials).

3) The ground insulation layer is calculated in cubic meters according to the net area between the walls of the envelope structure multiplied by the design thickness, without deducting the volume occupied by columns and stacks.

4) The wall insulation layer shall be calculated in cubic meters according to the net length of the insulation layer multiplied by the size height and thickness of the insulation layer in cubic meters for the external wall and the internal wall according to the size of the insulation layer, and the volume occupied by the opening of the refrigerated door and the opening of the pipe through the wall shall be deducted.

5) The column package insulation layer is calculated by multiplying the length of the centerline of the insulation layer of the column shown in the figure by the height and thickness of the size shown in the figure in cubic meters.

6) Other thermal insulation:

1. The pool tank insulation layer is calculated in cubic meters according to the length, width and thickness of the pool tank insulation layer shown in the figure. Among them, the pool wall is calculated according to the wall, and the bottom of the pool is calculated according to the ground.

2. The thermal insulation part around the side wall of the door opening shall be calculated in cubic meters according to the size of the thermal insulation layer shown in the figure, and incorporated into the thermal insulation engineering quantity of the wall.

3. The column cap thermal insulation layer is incorporated into the ceiling thermal insulation layer according to the volume of the thermal insulation layer shown in the figure.

7) Exterior wall insulation according to the design of the actual paving area in square meters to calculate the amount of work.

The insulation area of the exterior wall should be calculated based on the actual pasting area of the insulation board, such as the area of the hole on the basis of the area of the exterior wall, you also need to add the area of the side of the hole, but it should be emphasized here that when calculating the area of the side of the hole, the width should be subtracted from the thickness of the insulation layer.

It is all settled by the actual area, and the side of the window is counted together with the large surface.

Floor Area* This algorithm is rough and rough.

The thickness of the insulation multiplied by the length of the insulation.

The area of external wall insulation construction should be multiple of the total external wall construction area, that is, the perimeter of the building * high, and then deduct the area occupied by door and window openings, balcony floors, and air-conditioning panels.

The thermal insulation layer should be distinguished from different thermal insulation materials, which need to be calculated according to the thickness of the actual paving and in cubic meters, and the thickness should be calculated by net thickness;

If the ground insulation layer is calculated according to the structure of the hearth, the net area * design thickness is used, and the volume occupied by the column and stack is not deducted; The wall insulation layer needs to be calculated in cubic meters according to the center of the insulation layer, the net length of the internal wall * size height and thickness, and the volume occupied by the pipe hole should be deducted.

Styrofoam: Thermal conductivity: (1) Density of 100kg m3 thermal conductivity; c Heat storage coefficient period 24h (2) The density is 30 and the thermal conductivity is the heat storage coefficient.

Crack resistant mortar: Thermal conductivity: Heat storage coefficient.

Waterproof putty: Thermal conductivity: Thermal storage coefficient:

Coatings: Thermal conductivity: Thermal storage coefficient:

The parameters are found out for you, so do the math yourself. You're an HVAC, right, don't you know the most basic?

What about the total area? Are there any irregular wall sections? What is the unit price of your board? Duration?

Exterior wall insulation peers are welcome to add these numbers.

Enter the communication platform for everyone.

The problem is not very clear, the floor area of the building includes the thickness of the insulation layer of the external wall, and the area of the first floor is calculated by the enclosure area of the external wall above the foot.

Construction area: indoor area + shared area and external wall insulation.

When calculating the area, the length of the centerline of the wall should be calculated to the outside of the insulation layer, that is, the area should be calculated with the outside of the insulation layer.

The size of the surface of an object or the flat figure enclosed by it is called their area. The area is the size of the flat figure occupied, square meters, square decimeters, square centimeters, is recognized.

The insulation area generally accounts for about 40% of the construction area, and the house with a high-rise unit can account for 80%.

1. Exterior wall insulation = area of the outer edge of the wall - side wall of the door and window openings (added to the outside of the insulation layer).2. Exterior wall plastering = area of the outer edge of the wall - door and window openings + side wall (outside without insulation layer) Second shouting poor bridge External wall insulation area Zheng Meng: about times the construction area. Generally, after completion, it is calculated according to the actual area of sticky socks.

That is, the perimeter of the building is multiplied by the total height, deducting the openings of doors and windows, the floor of the balcony and the air conditioning panel.

Summary. Under normal circumstances, the area of external wall insulation is about 50% of the entire wall area. If you need to calculate more precisely, you can multiply the bottom edge of the entire building by the height and subtract the area of the door and window glass, balcony floor and air conditioning panel.

Hello, I have seen your question and am sorting out the answer, please wait for a while Generally, the area of external wall insulation is about 50% of the entire wall area. If you need to calculate a more accurate experience, you can multiply the bottom edge of the entire building by the height and subtract the ballast area of the door and window glass, balcony floors, and air-conditioning panels.
