Insulation installation is a crucial step to reduce heat transfer between the interior and exterior of buildings, enhance energy efficiency, and maintain a comfortable indoor temperature. Here are some key points for insulation installation:
I. Pre-construction Preparation
Material Preparation:
Select appropriate thermal insulation materials according to design requirements, such as polystyrene boards, rock wool boards, glass wool, etc. Ensure that the materials meet national quality standards and possess excellent thermal insulation, fire resistance, and durability.
Prepare auxiliary materials such as adhesives, anchoring hardware, glass fiber mesh, etc.
Tool Preparation:
Common tools include putty knives, notched trowels, level rulers, electric mixers, hammer drills, and more.
Ensure the integrity and suitability of tools for smooth construction progress.
Base Treatment:
Clean the subgrade for construction, removing dust, grease, loose particles, etc., to ensure the surface is smooth and dry.
For uneven subgrades, leveling treatment is required, which can be done using cement mortar or other suitable materials.
II. Construction Process
Thermal Insulation Board Adhesion:
The thermal insulation boards are adhered to the base layer using an adhesive, which should be applied evenly and generously to ensure a strong bond between the insulation boards and the base layer.
Insulation board joints should be tightly sealed; no gaps are allowed. For larger gaps, the insulation material should be used to fill them.
Fasten the insulation boards with anchoring bolts, ensuring the number and placement meet the design specifications.
Fiberglass mesh laying:
Fiberglass mesh is laid on the surface of the thermal insulation board to enhance the crack resistance of the insulation system.
The glass fiber mesh should be flat and taut, without any wrinkles or curled edges.
The overlap width of the mesh fabric should meet the design requirements, generally not less than 100mm.
Finish plastering application:
Apply a skim coat mortar on the glass fiber mesh, ensuring the thickness meets the design specifications.
Apply the plaster mortar in two coats, with the first coat not exceeding a certain thickness, then allow it to dry before applying the second coat.
The skim coat砂浆 should be flat and smooth, free of cracks or hollows.
Section 3: Construction Quality Control
Material Quality Control:
Thoroughly inspect the quality of insulation materials and auxiliary materials to ensure they meet design specifications and relevant standards.
Sample inspections of incoming materials are conducted; materials that do not meet the standards are not to be used.
Construction Process Control:
Enhance supervision and inspection of the construction process to ensure compliance with standard requirements.
On-site supervision is conducted for critical stages, such as the application of thermal insulation boards, anchoring components, and laying of glass fiber mesh.
Promptly identify and correct quality issues during construction to ensure the quality of the insulation system.
Product Protection:
Upon completion of the thermal insulation work, timely product protection should be implemented to prevent damage.
No heavy impacts or hammering on the thermal insulation system to prevent damage to the insulation layer.
The quality of thermal insulation installation directly affects the energy-saving effect and service life of the building. Therefore, it is essential to strictly adhere to the specifications during the construction process to ensure the quality of the installation.
