Frequently Asked Questions

Loft Insulation Questions Answered

How much money does loft insulation save?
A typical home loses around a quarter of its heat through the roof. Insulating an uninsulated loft can save hundreds of pounds a year on heating, and topping up thin insulation still makes a worthwhile difference.
What depth of loft insulation do I need?
Current guidance is around 270mm to 300mm of mineral wool. Many older homes have 100mm or less, which is well below what the property needs to hold its heat.
Can you top up my existing insulation?
Yes. If your existing material is dry and in good condition we lay new insulation over it to bring the loft up to the recommended depth, which is quicker and cheaper than starting from scratch.
How long does loft insulation take to install?
Most lofts are done within half a day, and even larger properties are normally finished in a single visit with no mess left behind.
Will loft insulation cause condensation?
Only if a loft is sealed up with no airflow. We make sure ventilation paths at the eaves stay clear so the roof space can breathe, which keeps condensation and mould away from your timbers.
Can I still use my loft for storage?
Yes. Raised boarding can be fitted over the insulation so you keep storage space without squashing the insulation, because compressed insulation loses much of its effect.
Does loft insulation help in summer too?
It does. The same layer that keeps heat in during winter slows the roof heat entering your rooms in warm weather, so upstairs bedrooms stay more comfortable.
How long does loft insulation last?
Mineral wool insulation lasts around 40 years or more if it stays dry. It is one of the best value improvements you can make to a home.
Is there any help available with the cost?
Energy efficiency schemes in Northern Ireland come and go, and eligibility rules change. Ask us when you enquire and we will tell you what is available at the time.
Why use North Coast Damp Proofing Limited for insulation?
Because we look at the whole picture. As damp specialists we check the roof space for condensation, leaks and timber problems before insulating, so you never trap a problem under a new layer of insulation.
