Knauf Loft Insulation Installation
Improve your home’s energy efficiency with professionally installed Knauf loft insulation. We install traditional mineral wool loft insulation in homes across the UK, with a free survey to assess your existing insulation, ventilation and the most suitable solution for your property.
Traditional Knauf Loft Insulation for Your Home
Knauf loft insulation is a proven mineral wool solution for insulating cold lofts at ceiling level, helping to reduce heat loss through the roof and improve the energy efficiency of your home.
We install Knauf insulation between and over the ceiling joists to achieve the appropriate overall depth for your property. During your survey, we’ll assess your existing insulation, loft access and ventilation before recommending the most suitable installation.
Knauf Space Loft Roll is manufactured from up to 80% recycled glass and uses ECOSE® Technology. It is non-combustible with a Euroclass A1 fire classification and provides reliable thermal performance while remaining soft and low in dust.
Where required, existing insulation can be removed before installation, and we can install lap vents to help maintain suitable airflow through the loft space.
Why Choose Knauf Loft Insulation?
Knauf mineral wool is one of the most established forms of loft insulation used in UK homes. It provides reliable thermal performance and is particularly well suited to traditional cold lofts where insulation is installed at ceiling level.
Its flexible roll format allows insulation to be fitted between and over the ceiling joists, helping create consistent coverage across the loft floor and reduce heat loss through gaps or poorly insulated areas.
Knauf Space Loft Roll is non-combustible, manufactured using ECOSE® Technology and made from up to 80% recycled glass. It is also soft to handle and low in dust and VOCs.
Whether you’re topping up existing loft insulation or replacing material that is old, damaged or no longer performing effectively, we’ll assess the loft first and recommend the appropriate installation for your home.
Traditional cold loft insulation is a proven approach in UK homes, but good performance relies on more than the insulation itself.
Airflow, ventilation and the condition of the insulation all affect how a cold loft performs over time. Want to understand how a cold loft actually works? Read our guide:
