Pre-insulated Double-Wall Duct and Fittings
Double-wall spiral duct, bends, tees, reducers, couplings and dampers with the insulation built in
Overview
What it is for
Pre-insulated duct has an inner pipe, a layer of insulation and an outer pipe, made as one part. There is no lagging to wrap on site, the outside stays clean, and the insulation cannot be damaged during installation.
The range covers the full system, not just straight pipe: bends from 90 to 15 degrees, saddle and boot tees, 45 degree tees, Y-pieces, crosses, reducers, couplings, end caps, dampers and insulated motorised dampers.
Insulation thickness and the inner and outer diameters are confirmed per item when we quote.
Make it yourself or buy it finished? If you run your own round duct, our SBTF-1602 spiral tubeformer and SBEM-1250 elbow machine make spiral pipe and bends in house. Many shops do both: make the high-volume sizes and buy the awkward fittings finished. See also how duct fittings are made.

Frequently asked questions
About pre-insulated duct and fittings
Why buy pre-insulated instead of lagging on site?
It saves the lagging labour, the finish is clean and the insulation is protected by the outer skin. It suits exposed runs and jobs where site time is expensive.
How long does production take?
Production time depends on the item mix and quantity and is confirmed at quotation. As a guide, a recent mixed order of about 1,900 bends and dampers was produced in 50 working days.
Do you have a price list?
No. Fittings are quoted per order from your take-off, because the price depends on the diameter, gauge, coating and quantity of each line. Send the list and we quote every line.
