"While adding loft insulation is certainly one way to improve your home's energy efficiency, making loft insulation mistakes can result in your hard work backfiring and leading to more problems than you even started with. However, follow the correct advice on how to insulate a loft and there's no doubt you and your home will reap the rewards. With building and roofing experts to hand, we're here to explain the most common loft insulation mistakes homeowners make so you can avoid a future that sees you ripping out your hard work and starting over again."
"Mistake one: lack of ventilation"
Loft insulation significantly improves home energy efficiency when installed correctly. Common installation mistakes can negate savings and create new problems that require ripping out and redoing work. Poor ventilation is a major risk because trapped moisture can lead to condensation, mold, and roof structure damage. Incorrect placement, inadequate depth, and compressed insulation reduce thermal performance. Failure to maintain access and blocking eaves ventilation channels also causes issues. Following proper guidance and using correct materials preserves insulation performance, prevents moisture problems, and protects the roof and building fabric. Attention to ventilation, installation technique, and maintenance delivers long-term energy and structural benefits.
