What is Glass wool ducts?

Glass wool ducts is a solution for air distribution…

Self-supporting air ducts*… Air duct made from a glass wool (duct board)

The duct is obtained by grooving, folding, stapling and taping

We Provide glass wool boards (with shiplaps and double-faced)

We provide a solution for air-ducts (system)

*An air duct is duct-pipe transporting air (conditioned/heated/treated/ non treated)

Air conditioning ducts

Types of ducts

1. Metal ducts

2. Glasswool ducts

3. Plastic ducts

4. Flexible ducts

• Workshop

• Need thermal & acoustic insulation ()

• Two works: duct + insulation ()

• Not adaptable to changes in site ()

• Appear as “robust” () but ?

Can be installed on-off site ()

GW thermal & acoustic insulation ()

High airtightness ()

One operation (no additional insulation) ()

Double faced boards ()

Appear as “less robust” but?

Can be installed on/ off site ()

Foam thermal () (not acoustic ()) insulation

One operation (not add thermal insulation) ()

Need auxiliary profiles for mounting ()

Fire performance is bad (smokes) ()

Can be installed on site ()

Provide thermal insulation with GW ()

Poor acoustic performance ()

Poor resistance to pressure ()

High pressure drops, ()

Usually limited in length by Regulations()

• Rigid glasswool boards (self-supporting air ducts)

• Glasswool provides thermal and acoustic insulation

• Unique operation (not additional insulation)

• Duct section obtained after grooving the board,

folding, and stapling and taping joints

• Can be installed on-off site

• Double faced boards:

Inside the duct (“inside

face”): acoustics /

TWIGA

IMO certified by-

SAINT GOBAIN


Specification

Product Name: Twiga Acoustic Board

• Thickness: 25MM thick Rigid board

• Density:70 to 80kg

• Laminations

Top: RP White Tissue + Black Glass Cloth

Bottom: RP Tissue + Aluminum foil

• Rigidity: With increased binder content up to 18%

• Size of the Board:

Standard will be 3 M x 1.2 M

Also Available in 1200 mm X 600 mm

TWIGA

IMO certified by-

SAINT GOBAIN


Advantages

• Reduce room space as its is 25 mm thick

• High acoustic properties with 80 kg material

• Highest acoustic absorption for 25 mm thickness panels

0.70 NRC.

• Laminar long and resilient fibers in rigid board form.

• Better dimension- 1.2 m x 3 m – Advantage to cover internal walls

vertically. Also available in 1.2 m x 0.6 m

• Safe from water because the back side has aluminum facing

• No supporting perforations required due to its rigidity and both side

Laminations hence reduce the cost of channel and other

accessories.

• Can directly fixed to the AHU wall, ceiling or with frame to create

thin Air layer cavity behind the board for better acoustic results
