Rockwool fixing method
Label film
The rock wool fixing method is a key link in the rock wool insulation construction, which directly affects the stability, durability and insulation effect of the insulation system. Depending on the construction scene and rock wool products, the fixing method also varies. The following is a detailed description of the rock wool fixing method:
1. The importance of rock wool fixing method
- Ensure stability: The fixing method affects the fit between the rock wool and the base layer to prevent falling off or displacement.
- Improve insulation effect: The fixing method affects the density of the rock wool and reduces heat loss.
- Enhance durability: A reasonable fixing method can extend the service life of the insulation system.
- Adapt to different scenarios: Choose the appropriate fixing method according to the construction scene to ensure construction quality.
2. Classification of rock wool fixing methods
(1) Mechanical fixing
- Anchor bolt fixing:
- Method: Use plastic or metal anchor bolts to fix the rock wool board to the wall or roof.
- Advantages: Firm fixation, suitable for high-rise buildings and exterior wall insulation.
- Disadvantages: Complex construction and high cost.
- Applicable scenarios: Exterior wall insulation, roof insulation.
- Keel fixing:
- Method: Install keels on the wall or roof, and embed the rock wool board between the keels or fix it with screws.
- Advantages: Flexible construction, suitable for irregular walls.
- Disadvantages: Occupies a certain space and reduces the indoor usable area.
- Applicable scenarios: Indoor partition walls and ceiling insulation.
(2) Bonding fixation
- Point bonding method:
- Method: Apply adhesive (such as polymer mortar) on the back of the rock wool board, distribute it in dots or strips, and then stick it to the base.
- Advantages: Simple construction and low cost.
- Disadvantages: Low fixing strength, suitable for low-rise buildings.
- Applicable scenarios: Exterior wall insulation of low-rise buildings.
- Full-bonding method:
- Method: Apply adhesive to the back of the rock wool board and then stick it to the base.
- Advantage: High fixing strength and good insulation effect.
- Disadvantage: Complex construction and high cost.
- Applicable scenarios: External wall insulation of high-rise buildings.
(3) Composite fixing
- Bonding + anchor bolt fixing:
- Method: First use adhesive to stick the rock wool board to the base, and then reinforce it with anchor bolts.
- Advantage: High fixing strength, suitable for high-rise buildings and external wall insulation.
- Disadvantage: Complex construction and high cost.
- Applicable scenarios: External wall insulation and roof insulation of high-rise buildings.
(4) Other fixing methods
- Wire mesh fixing:
- Method: Cover the surface of the rock wool board with wire mesh and fix it with anchor bolts or screws.
- Advantage: Enhance the tensile strength of the rock wool board and apply it to external wall insulation.
- Disadvantages: Complex construction and high cost.
- Applicable scenarios: External wall insulation, pipe insulation.
- Fixing with battens:
- Method: Use metal or plastic battens to fix the rock wool board to the keel or base layer.
- Advantages: Simple construction and neat appearance.
- Disadvantages: Low fixing strength, suitable for indoor insulation.
- Applicable scenarios: Indoor partition walls and ceiling insulation.
3. Factors for selecting rock wool fixing methods
- Construction scenarios: External walls, roofs, indoor partition walls and other scenarios have different requirements for fixing methods.
- Rock wool types: The fixing methods of rock wool boards, rock wool felts, rock wool pipes and other products are different.
- Base materials: Concrete, brick walls, metal plates and other base materials have different requirements for fixing methods.
- Insulation requirements: High-rise buildings, low-temperature environments, etc. have high requirements for fixing strength and insulation performance.
- Cost budget: The construction cost and material cost of different fixing methods vary greatly.
4. Construction steps of rock wool fixing method
- Base treatment: Clean the surface of the base to ensure it is flat, clean and not loose.
- Rock wool board cutting: Cut the rock wool board according to the construction requirements to ensure the appropriate size.
- Fixing construction:
- Adhesive fixation: Apply adhesive and paste the rock wool board.
- Mechanical fixation: Install anchor bolts or keels to fix the rock wool board.
- Joint treatment: Fill and seal the joints.
- Surface treatment: Cover with wire mesh or waterproof layer and decorate the surface.
5. Common problems and solutions of rock wool fixing method
(1) Rock wool board falls off
- Cause: Improper selection of fixing method or poor construction quality.
- Solution: Reselect the fixing method to ensure construction quality.
(2) Shift of rock wool board
- Reason: Insecure fixation or improper joint treatment.
- Solution: Strengthen fixing measures and re-treat joints.
(3) Poor insulation effect
- Reason: The rock wool board is not tightly attached to the base layer.
- Solution: Use full bonding or composite fixing method to ensure tight fit.
6. Application scenarios of rock wool fixing method
- External wall insulation: Adopt bonding + anchor bolt fixing or wire mesh fixing.
- Roof insulation: Adopt anchor bolt fixing or pressure strip fixing.
- Indoor partition wall: Adopt keel fixing or pressure strip fixing.
- Pipe insulation: Adopt wire mesh fixing or bonding fixing.
Through reasonable fixing methods, the stability, durability and insulation effect of the rock wool insulation system can be ensured to meet the needs of different construction scenarios.
