Colorduct II

At HAS-Vent we believe in developing every aspect of a building’s potential. Flying in the face of the convention that states that air conditioning, ventilation and warm air heating systems are architectural and design no-go areas, we pioneered the concept of converting exposed ducts into pleasing aesthetic features. As a result ductwork came into the open.

Colorduct II was developed in the mid 8O’s by Hotchkiss Spiral Tubes now trading as HAS-Vent. HAS-Vent is now one of the leading suppliers of ventilation ductwork and accessories in the UK with a Midlands based head office and a national branch network. Our innovative ducting systems were quickly added to blueprints for all types of building where previously the idea of leaving building services exposed would have been considered unacceptable.

Colorduct II conforms to the DW/144 specification.

Within this range you will find the appropriate solution to your ducting requirements – and an opportunity to tum a hidden utility into a conspicuous asset.

Technical Details

Why hide it?

Colorduct II is a highly visible, highly versatile, low cost system of coloured ducting that will enhance its environment. Only available from HAS-Vent, this pre-coloured ductwork system is especially suitable for public places such as airports, banks, office developments, business parks, atria, schools, roof tops, cafeterias, leisure centres and swimming pools.

Colorduct II enables ducting to become an essential design factor in air conditioning, ventilation and warm air heating applications. Resilient, long-lasting with low maintenance costs, it is available in circular, flat oval and rectangular formats, contributing a unique design flavour to any building where ductwork is on view.

 

 

 

 

 

The Colorduct II palette

Colorduct II special polyester powdered colour ducting is suitable for ductwork conforming to DW/144 specification, and is therefore highly flexible in application across a wide array of sizes. It’s smooth, yet very tough non-inflammable coating offers a film thickness of no less than 50 and no more than 120 microns in standard circular and oval formats (rectangular also available) – and is the obvious choice for interior applications.

Colorduct II is available in a range of colours. Accent colours are brighter, more heavily pigmented and for that reason are more expensive. Colorduct II has the advantage of being available in any British Standard colour in both gloss and matt finishes.

Specifiers are asked to remember that when Colorduct II is included in tender documents, we are unable to accept responsibility for the matching of colours if the total system of tubes and fittings is not purchased from HAS-Vent. If tonal consistency is critical a single contract should be sourced at the same time from the one production batch. If at the time of tendering the final colour has not been agreed, we reserve the right to quote for supply based on white or our nearest stock colour.

Construction

The ductwork is made from Hot Dipped Galvanised Steel DX51D Z275.

Straight ducts are spirally wound and can be produced at any length required. The maximum length for internally lined duct varies upon the diameter as stated below

  • Up to 150mm Ø – 1m Long
  • 150mm Ø – 1000Ø – 1.5m Long

All fittings can be Pre-Insulated both pressed and fabricated.

All parts are produced in line with DW144 specifications.

All material is supplied and certified to the latest version of BS EN IS 9001.

Joining Options

The standard connection that we produce on the Pre-Insulated Ductwork is where the foam is trimmed back 40mm on the spiral duct to allow the fitting or couplers slip joint to be pushed inside so there is no gaps in the foam.

The second option is a flanged joint using METU flanges rather than standard couplings.

Duct Fixing

HAS Pre-Insulated Ductwork can be mounted in the same way as standard ductwork such as suspension rings or Zip Clip wire system.

Insulation

The insulation is an Akustifoam Akusticell foam which is a black high density acoustic insulation material, it is made of polyurethane foam. Due to its non-flammability features it does not melt, form liquid drops or change its mineral structure. It does not contain halogen or heavy metals and does not become mouldy when exposed to humidity or moisture.
