What is the lead time for bespoke cast iron guttering?

Bespoke and copy cast iron rainwater goods typically have a lead time of 12 to 14 weeks from order confirmation. This covers pattern-making, casting, finishing, and quality inspection. Stock items are typically despatched within 5 to 7 working days, and non-stock standard profiles within 7 to 10 working days.

Are these rooflight openers suitable for use with Lumen Rooflights?

Are these rooflight openers suitable for use with Lumen Rooflights?

Yes. Our telescopic screw-jack openers and pole-operated handles are compatible with Lumen Rooflight systems. They are also suitable for use with other timber-framed rooflights and skylights fitted with appropriate catches or stays. If you are unsure of compatibility, call us on 0333 987 4452 and we can advise.

Do cast iron radiators work with heat pumps?

Do cast iron radiators work with heat pumps?

Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
