KIMMCO Products - KIMMCO Duct Insul (KDI)

Application

External insulation of rectangular and circular air ducting and air handling equipment.

Description

KIMMCO Duct Insul is in the form of flexible rolls, semi-rigid and rigid slabs manufactured from stable glass fibers bonded with thermo-setting resins, and free from coarse fibers and shot. Easy to handle and cut to fit rectangular ducts and air handling equipment.

Facings

KIMMCO Duct Insul is available unfaced or with a glass reinforced aluminium foil/kraft laminate facing (FSK) which combines a pleasing appearance with excellent vapour resistance.

Performances

Working Temperature:

Fibre 200 ºC

Foil face 100 ºC

Permeance:

KIMMCO Duct Insul has a high resistance against accidental puncture during handling, installation and maintenance.

Dimensionally stable under varying conditions of temperature and humidity, rot proof, odourless, non-hygroscopic and will not sustain vermin or fungus.

Thermal Conductivity

The low thermal conductivity of fiberglass products is due to the fact that they consist of more than 95% air which is trapped and kept stationary by the thin fibers.

Fire Safety:

Fibres are Non combustible when tested in accordance with BS 476 (part 4), ASTM E 84, 136.

Glass reinforced aluminium/kraft laminate facing (FSK) are U.L. classified as
follows:

Flame spread : 15
Smoke developed : 0

Moisture Absorption:

Less than 1% by volume when tested in accordance with ASTM C 553.

KIMMCO Duct Insul does not absorb moisture from the ambient air nor water by capillary attraction. Only water under pressure can enter the insulation products, but that will quickly dry out owing to the material's open cell structure.

FSK faced DuctInsul comply with ASTM E 96 Desiccant Method. Permeance not to exceed 0.02 perms (Federal Standard HH-B-100 B Type 1).

Non Toxic

KIMMCO DUCT INSUL is not hazardous to health (See KIMMCO MSDS).

Typical Fixing Details

Installation 1

Ensure surface of duct is dry and free from dust or grease. Cut insulation to required length to fit around the duct making sure that edges are straight.

Apply insulation adhesive to duct surface in strips approx. 15 cm wide. Underside of duct should be completely coated with adhesive to prevent sagging.

Wrap insulation, foil face up, to the prepared duct surface once adhesive has become tacky, or as instructed by manufacturer, making sure that all edge joints are closely butted.

Apply uniform hand pressure to outside surface of insulation to obtain good bond.

Tape all longitudinal and transverse joints with a good quality self adhesive insulation tape. Seal any puncture points in insulation around hangers etc. with tape.

If lacing wire is used for additional security a light gauge galvanised angle should be fitted on each edge to prevent wire from cutting into insulation.

Installation 2

Ensure surface of duct is dry and free from dust and grease. Cut insulation to required length to fit around the duct making sure that edges are straight.

Depending on size of duct fit 2 or more rows of insulation fixing pins to each face of duct at centres of 30 - 50cm. Pins can be self adhesive type, bond-on type or stud welded.Carefully position insulation over the pins, pressing firmly so that pins penetrate through the insulation. Fit spring clip or lock washer over pins pushing them down until tight against insulation. Snip off any excess shank from pin. Seal all joints and openings with self adhesive tape.

Installation 3
Where Duct insulation requires protection against mechanical damage or is to be used outdoors the insulation can be wrapped with wire mesh to which an application of quick setting compound or cement can be applied.

Installation 4

Circular ducts can be easily insulated with Duct Insul insulation. Cut Duct Insul to suit the circumference of duct. Clean surface of duct to remove dust and grease. Apply insulation adhesive in strips approx. 15 cm wide. Wrap insulation onto duct applying firm hand pressure to obtain maximum bond. When applying each wrap of insulation ensure that longitudinal joints are kept in line. Seal all joints with self adhesive tape. Large ducts can be reinforced with self adhesive tape, metal or nylon strapping.
