Glass or stone wool?

Glass wool rolls are light and economical for lofts. Stone wool slabs are denser and often chosen for acoustics and fire stopping.

Keep it ventilated

When insulating a loft, keep eaves vents clear so the roof space stays ventilated.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Before your Washington delivery arrives

Rolls are compressed and wrapped; they are light but take up space, so tell us if storage is tight. Washington is inside our standard mainland delivery area.

• In summer Washington gets around 17h 21m of daylight, but early deliveries still beat the traffic and give the longest working day.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
