To understand your attic's insulation, consider existing materials like yellow fibreglass or rockwool, typically installed at depths of 100mm or less. While effective to some extent, they may require inspection for wear or gaps. Yellow fibreglass offers affordability but might need supplementation. Rockwool provides durability but can degrade over time. Identifying these materials helps gauge insulation effectiveness and informs decisions on upgrades for better comfort and energy efficiency. For optimal energy efficiency, consider upgrading to eco-friendly insulation solutions.
