Loft insulation is a layer of insulating material laid across the floor of your loft space, between and over the ceiling joists. It works by trapping the warm air rising from your living space below, preventing it from escaping through the roof. The recommended depth for UK homes is 270mm.
Around 25% of the heat in an uninsulated home escapes through the roof. Loft insulation stops that heat loss, keeps your home warmer and reduces your energy bills.
Why Loft Insulation Matters In Manchester
Manchester's climate means homes need heating for much of the year. An uninsulated loft lets a quarter of your heat escape — money literally going out through the roof. With energy prices high, loft insulation is the fastest way to cut your heating costs.
Most Manchester homes can be insulated in a single day.
Types Of Loft Insulation
Blanket Insulation
The most common and cost-effective option. Rolls of mineral wool laid between and over the joists.
Rigid Board Insulation
Rigid foam boards, ideal for loft conversions or where a floor is needed for storage.
Blown Insulation
Loose-fill material blown into place, ideal for awkward spaces and uneven joist layouts.

Loft Insulation Depth Guide
The recommended depth is 270mm (about 11 inches) of mineral wool. This achieves the current building regulations U-value of 0.16 W/m²K.
If your loft has less than 100mm, topping up is highly recommended — the first 100mm saves the most energy.
Loft Insulation And Ventilation
Proper ventilation is essential. Insulation must not block the airflow at the eaves, or condensation can form in the loft. A professional installer will always maintain ventilation paths — another reason to use a local expert.
