Let our experts evaluate your home’s efficiency and recommend the best heating solutions.
Loft insulation is one of the most effective and affordable ways to improve your home’s energy efficiency. Since heat naturally rises, an uninsulated or poorly insulated loft allows a significant amount of warmth to escape through the roof, making your heating system work harder and increasing your energy bills.
At AAN Insulation Ltd, we provide professional loft insulation solutions designed to help homeowners enjoy a warmer, more comfortable property while reducing energy consumption and lowering carbon emissions. Whether your home needs new insulation or an upgrade to existing materials, our experienced team can recommend the right solution for your property.
Loft insulation is the process of installing insulating materials within your loft or attic space to reduce heat loss through the roof. In most homes, insulation is fitted between and over the loft floor joists, creating a highly effective thermal barrier that keeps warm air inside during colder months.
Modern loft insulation not only improves winter warmth but also helps reduce overheating during summer by slowing the transfer of external heat into your home.
Properly installed loft insulation can continue performing effectively for decades with minimal maintenance, making it one of the best long-term investments for improving your home’s energy efficiency.
Unlike a traditional gas or oil boiler that generates heat by burning fuel, an air source heat pump transfers naturally occurring heat from the outside air into your home’s heating system. The process is simple:
Modern air source heat pumps continue to operate effectively even in temperatures as low as -25°C, making them suitable for the UK’s climate
Blanket insulation is the most common form of loft insulation used in UK homes. It is typically manufactured from mineral wool, glass wool or rock wool and supplied in large rolls.
The insulation is laid between the loft floor joists before a second layer is installed across the joists. This method helps minimise thermal bridging and achieves the recommended insulation depth for maximum efficiency.
Reflective foil insulation consists of multiple layers of aluminium foil combined with insulating materials. Rather than slowing heat transfer through its thickness alone, it reflects radiant heat, helping improve the overall thermal performance of the roof space.
Reflective insulation is commonly installed beneath roof rafters or used alongside traditional loft insulation as an additional insulating layer.
Periodically check for signs of water leaks, damp patches, mould or pest activity, as these can affect insulation performance.
Proper airflow within the loft helps prevent condensation and moisture build-up, protecting both the insulation and your roof structure.
Heavy storage placed directly on insulation can reduce its effectiveness by compressing the fibres. If you require loft storage, raised loft boarding should be installed above the insulation to maintain its full thermal performance.
