1Why should use aluminum foil insulation?

Approximately 75% of heat transmission is by radiation, most material used on building absorb radiantion heat and re-radiate it, which makes the room temperature much higher than outside, and have Air-conditioning to work constantly. But aluminum foil insulation can reflect 97% radiation heat, so it save your energy bill and provide you comfortable room temperature.

2How does Reflective Aluminum Foil Insulation work?

Reflective Aluminum Foil Insulations don't absorb heat, they block the flow of radiation.? Installing Reflective Aluminum Foil between the heat source (sun) and an existing insulation will improve the effectiveness of the R-Value rated insulation.?The reason is that only little part of the heat is now hitting the R-Value rated insulation and therefore, it will take longer for it to absorb 100% of its potential thereby holding the heat longer before passing out the back side into the room. Reflective Aluminum Foil reflects up to 97% radiant heat striking its surface.

3,How to install Reflective Aluminum Foil Insulation correctly?

It is important to maintain at least a 3/4" air space on the side of the radiant barrier you want to reflect heat. So you can prevent introducing any conductive heat flow to the aluminum to the aluminum foil facing and improve the efficiency for insulation.

4,What does a acoustic pipe lagging product do?

acoustic pipe lagging products dramatically reduce the amount of noise that transmits through the walls or casing of ductwork, steel or PVC piping, valves, sheet metal enclosures, VAV units and fans.

5, Is this product the same as the flexible, foil-faced fiberglass duct?

No. A foil faced fiberglass duct does not include the loaded vinyl noise barrier, the key ingredient for noise reduction.

6, Is the lagging material fire retardant?

Yes, it passed the test of AS/NZS1530.3

7,How to How to install the acoustic lagging

Ensure that surface of outer pipe is clean and free of dust etc. Cut insulation to suit either bends or straight lengths. Wrap insulation in place and ensure no gaps and that butt joins are well sealed. For straight lengths use a minimum 50mm overlap. Use foil face self-adhesive tape ensuring that surface to be taped is clean and dust free. On straight runs, foil tape, cable ties, or packaging strapping should be used as a band approximately every 400-500mm wrapped around the insulation. All longitudinal joins to be overlapped and taped. Joins should be facing downwards to avoid unnecessary weight and strain on the tape. Important to ensure there are absolutely no gaps.
