Before your Penarth delivery arrives

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Penarth, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Mineral Wool Insulation questions

How thick should loft insulation be?

270 mm in total is the common recommendation, usually as 100 mm between the joists and 170 mm across them.

Can you deliver mineral wool insulation to a site with restricted access in Penarth?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

How many rolls do I need for my loft?

Divide the loft floor area by the coverage printed on the roll, for each layer. Coverage varies by brand and thickness; a 100 mm roll typically covers around 8 m² and a 170 mm roll around 5 m².

Can I add other materials to my Penarth delivery?

Yes. Put everything on one list, from mineral wool insulation to fixings and PPE, and we will price it as one delivery where the products can travel together.
