Knauf mineral wool is the go-to insulation for the majority of Bournemouth lofts, and for good reason: it's effective, long-lasting, naturally fire-resistant and excellent value. We lay it between and over the joists to the recommended 270mm depth, slowing heat moving in either direction — keeping rooms cooler under a hot summer roof and warmer in winter.
As well as steadying the temperature, mineral wool dampens noise — a welcome bonus near Bournemouth's busier roads, the Wessex Way (A338) and the seafront. We take care to keep it clear of eaves ventilation and any downlights, so your loft stays both comfortable and healthy.

If you have a standard open loft used mainly for storage, mineral wool is almost always the most cost-effective way to a more comfortable home — cooler upstairs in summer and warmer in winter. Many Bournemouth properties still have old, thin or compressed insulation well below today's standard — topping it up to 270mm makes an immediate difference to comfort and bills.
It pairs perfectly with loft boarding when you also want usable storage above your insulation.
The current recommended depth is around 270mm of mineral wool. Many older Bournemouth lofts have far less — often 100mm or below — so topping up delivers a noticeable improvement.
Usually yes. If the existing layer is dry and in good condition, we can top it up to the right depth. If it's damp, mouldy or compressed, we'll advise removing and replacing it.
Mineral wool is a good sound absorber, so many homeowners notice less outside noise as well as a more comfortable home year-round.
