What is the thinnest part of the roof insulation required by the code?

Because the drawing design must have building energy saving requirements, all roof insulation materials and thicknesses are generally clearly stated in the construction drawings, generally block-shaped insulation boards with a thickness of more than 50mm; In the illustrative atlas of architectural practices, there is only a statement that the thinnest part of the slope finding material is 40mm thick, such as cement perlite slope finding.

The thickness of the building insulation board below 10 meters of external wall insulation should not be more than 60mm, the thickness of the building insulation board above 10 meters should not be more than 50mm, and the thickness of the insulation board of doors and windows should not be less than 20mm.

The insulation board is easy to understand, which is the board used to insulate the building. The insulation board is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polyinclusions, which is made by heating and mixing while injecting a catalyst, and then extruded and pressed out to form a rigid foam plastic board, which has moisture-proof and waterproof properties, which can reduce the thickness of the building envelope structure, thereby increasing the indoor use area.

The thickness of this system is calculated as the floor area. The special binder pastes the polystyrene board with a thickness of 50 thickness, the rubber powder polystyrene particle leveling is 10 thick, and the anti-cracking mortar composite alkali-resistant glass fiber grid board is 5 thick, and the thickness of 50 + 10 + 5 = 65 is counted.

The design thickness of the inverted roof insulation layer should be increased by 25 according to the calculated value, and the minimum thickness should not be less than 25mm.

Insulation board: easy to understand is the board used to insulate the building. Insulation board is made of polystyrene resin as raw material plus other raw materials and polyinclusions, through heating and mixing while injecting catalyst, and then extrusion and extrusion molding to manufacture rigid foam plastic board, which has moisture-proof and waterproof properties, which can reduce the thickness of the building envelope structure, thereby increasing the indoor use area.

The thickness of the insulation depends on the local climate and the requirements for room temperature.

Exterior wall insulation is composed of insulation materials, and the structural layer that plays a role in thermal insulation in the external insulation system. According to the energy-saving standards promulgated by the state, from October 1, 2001, it is stipulated that the newly planned real estate must be made mandatory to do external wall insulation.

The choice of insulation thickness is related to the cost of energy-saving buildings and the economy of operating costs. The mathematical model of calculating the economic thickness of the insulation layer by the life cycle consumption analysis method considers the heating energy consumption of the building in its life cycle, which has the characteristics of scientific, simple and convenient.

When there is a lack of heating system data, the use of design specifications has good pertinence and adaptability, has a certain reference and application value for engineering design, and can be used for the design and calculation of new or old building renovation and new insulation materials.

The thickness of the roof insulation layer is calculated according to the weighted average thickness, and the drainage length * slope 2 + the thickness of the thinnest point.

If the aspect length is not the same, the average thickness is also different, and the total volume of the calculated volume of each block and the average thickness of each block divided by the total roof area is its weighted average thickness, plus the thinnest thickness. It's a bit complicated, but precise.

For example, the thinnest part is 20mm, 2% slope, there is a slope on both sides, and the average thickness of the roof insulation layer with a roof span of 15 meters is calculated as: [20mm + (20mm + 15 * 1000 * 2% 2) mm] 2 = 190mm 2 = 95mm.

The thickness of the roof insulation layer is generally given in the drawing design, and you can purchase and construct it according to the design content, without calculation.

Dear, hello, I am happy to serve you, the answer is as follows: roof insulation thickness 70, coefficient, that construction materials should be about 45mm thick, according to my experience, the thickness of the building insulation board below 10 meters of external wall insulation should not be greater than 60mm, the thickness of the building insulation board above 10 meters should not be greater than 50mm, and the thickness of the insulation board of doors and windows should not be less than 20mm. The insulation board is easy to understand, which is the board used to insulate the building. The insulation board is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polyinclusions, injected with catalyst while heating and mixing, and then extruded and molded, which has moisture-proof and waterproof properties, which can reduce the thickness of the building envelope structure and increase the indoor use area by holding the beam.

The thickness of this system is calculated as the floor area. The special binder pastes the polystyrene board with 50 thicknesses, the rubber powder polystyrene particle leveling is 10 thick, and the anti-cracking mortar composite alkali-resistant glass fiber grid board is 5 thick, and the thickness of 50 + 10 + 5 = 65 is counted.
