Prevent Heat Loss with Loft Insulation

Heat naturally rises, which means a significant amount of warmth escapes through your roof if your loft isn’t properly insulated. Insulating your loft creates a thermal barrier to keep the heat inside your home where it belongs. This simple yet effective solution can reduce heating costs by up to 25% to make your home warmer in winter and cooler in summer.

How Loft Insulation Works

Loft insulation creates a thermal barrier between your roof and the rooms below to prevent heat from escaping. The Energy Savings Trust recommends a minimum depth of 300mm (12 inches) of insulation for optimal performance. If you're upgrading existing insulation or installing new material, we ensure full coverage for maximum energy savings.

FAQs

FAQs About Loft Insulation

Loft insulation typically lasts around 40 years or more, making it a long-term investment in energy efficiency. If installed correctly and kept dry, it often continues to perform effectively without needing replacement. However, it's worth checking every few years for signs of moisture, damage, or compression that could reduce its effectiveness.
In Northern Ireland, loft insulation must be installed to roughly 300 mm—ideally 400 mm or more—for most effective thermal performance and compliance. This is usually achieved through multiple layers laid in different directions, with careful attention to ventilation and full coverage.
Installing loft insulation typically takes between 2 to 4 hours for an average-sized home (around 3 bedrooms), assuming easy access and no complications. Larger properties or lofts with limited access, stored items, or damp issues may take longer—up to a full day in some cases.
