The
Ecoflange is manufactured by Construction & Engineering Products,
a division of Corus Special Strip. Fifty years experience of cold
roll forming technology means that Construction & Engineering
Products can design and manufacture to the most exacting tolerances
and consistent quality levels. |
||||
All
major products supplied by Denhaco fully conform to Duct Work Specification
144 (DW144), the UK Heating Ventilating Contractors Association
(HVCA) specification and have been tested and certified by the Building
Services Research and Investigation Association (BSRIA) in relation
to the DW144/TM1 test procedures for the HVCA. |
||||
| SLIDE – ON - FLANGES | ||||
The
Ecoflange is available in four internationally recognised standard
sizes (BS15, BS20, BS30 and BS40) and has a choice of material gauge
to suit every specification. |
||||
| The
Ecoflange facilitates rapid and accurate assembly of joints and
incorporates a number of significant features that set it apart
as a market leader in flange technology. The cantilever action on
the duct and the offset corner noses for even pressure all around
the face of the flange, ensure accurate assembly and sealing. In-line
injection of mastic into the flange, ensures that the edge of the
duct is firmly bedded into the sealant. All this, combined with
square hole fixing points, makes fast, single-handed installation
easy, an important breakthrough when working at height or in restricted
spaces. Denhaco ensured that the TM1 test requirements from BSRIA
were met, without needing to dimple the corners on J1, J2, J3 and
J4 flanges, saving customers time and money.

| BS15 DUCT FLANGE SYSTEM The BS15 Ecoflange was the first 15mm flange to be tested and available to the market, an innovation started by Denhaco. Estimates show that 60% of the ductwork currently made by using the 20 mm flange could be manufactured using the new 15 mm flange. The BS15 flange is fully tested to DW144/TM1 specification and can be used to manufacture ducts to J1 rating. |
||||
 |
 |
|||
Since its introduction, Denhaco have made changes to the flange and corner to assist customers in the manufacture of their ductwork. The complete BS15 Flange System can provide customers with a saving of approximately 15% on the cost of their flange requirements when compared with the cost of using a 20mm system. |
||||
BS20 DUCT FLANGE SYSTEM Tested to DW144/TM1, the BS20 flange is certified for J1 and J2 rated ductwork. The BS20 has a unique advantage as the corners do not have to be dimpled in order to meet these requirements. Denhaco believe that this is the only flange system that enables you to do this. |
||||
 |
 |
|||
BS30 DUCT FLANGE SYSTEM The BS30 flange performs to J3, J4 and J5 (J5 with a tie rod), and fully conforms to DW144/TM1. Again Denhaco believe that it is the only company to pass J4 without having to dimple the corners. |
||||
 |
 |
|||
SHORT BS30 & 31 CORNERS In response to requests from customers, Denhaco has introduced short BS30 and 31 corners, which remove the need to cut down standard sized corners for ducts when connecting to dampers. |
||||
BS40 DUCT FLANGE SYSTEM The BS40 flange can be used to manufacture ductwork up to J5 and J6 (J6 with a tie rod). The BS40 complements the Denhaco product range and ensures that Denhaco is the only name you need to specify. This flange is fully certified to DW144/TM1. |
