7. PALSUN® Thermal-Insulation Properties:
PALSUN is not an insulating material, but still offers lower thermal conductivity and better insulation than
comparable glass. When considering thermal efficiency and energy lose in winter (heating) or summer
(air-conditioning) PALSUN may contribute substantially in lowering total heating & cooling cost & energy
cutback for single glazing systems.

Notes:
1. Where PALSUN is mentioned it holds for PALGARD too. Its properties are identical to PALSUN.
2. PALSUN K-value shows significant drop (better insulation) as thickness grows.
Compared to glass 12mm
PALSUN glazing offers better insulation by more than 20% than its glass counterpart.
3.In between values to be calculated by interpolation.
8. PALSUN® Acoustic Properties:
Though less than half the weight of an equivalent glass pane, PALSUN glazing offers quite close sound
insulation properties along with much higher impact strength.
These combined properties make PALSUN glazing an excellent candidate for see-through sound barriers:
lightweight, easy to maintain or replace if necessary, highly transparent and vandal-proof.
PALGARD, with identical inherent basic properties and more, portrays even better advantages for
choosing it for the job(see page 7).

Notes:
1. Sound insulation/noise reduction values refer to single layered solid glazing pane of the depicted thickness for both
materials.
2. The somewhat higher acoustic reduction value of comparable glass results from its higher specific weight/density
(more than twice than that of polycarbonate).
