Installation Process of Blown-in Insulation
Installing blown-in insulation involves several key steps to ensure optimal performance. Here’s an outline of the process:
Equipment Required:
- Blower machine
- Insulation material (cellulose or fibreglass)
- Protective gear (masks, gloves, goggles)
- Measuring tools
Preparation:
- Assess the Area: Inspect the attic or wall cavities to determine the need for insulation.
- Seal Air Leaks: Use caulk or spray foam to seal any gaps or cracks that could allow air to escape.
Installation Techniques:
- Set Up Blower Machine: Position the blower machine outside the home and connect the hose to the insulation material.
- Load Insulation Material: Feed the insulation material into the blower machine according to the manufacturer’s instructions.
- Blow in the Insulation: Direct the hose into the desired area, filling the space evenly. Ensure the insulation is distributed consistently to avoid gaps.
- Monitor Coverage: Use measuring tools to ensure the insulation reaches the desired depth and R-value.
Importance of Proper Attic Ventilation and Air Sealing
Proper attic ventilation and air sealing are crucial when using blown-in insulation to prevent moisture buildup and maintain insulation efficiency.
Ventilation:
- Prevents Moisture Buildup: Adequate ventilation helps to prevent moisture accumulation, which can lead to mould and mildew growth.
- Regulates Temperature: Proper ventilation helps to regulate attic temperatures, reducing strain on HVAC systems.
Air Sealing:
- Enhances Insulation Performance: Sealing air leaks before installing insulation ensures that the insulation performs effectively.
- Reduces Energy Costs: Proper air sealing minimises drafts and heat loss, leading to lower energy bills.
