Spring

"Brings Nature in"- During summer and winter

Summer - With a special co-extrusion layer on the external side of the sheet under the UV protective layer "Spring" blocks the invisible IR solar radiation & heat. Result = Lower temperatures (less heat enters the structure), but still allow maximum light coming in.

Winter - Due to its outstanding insulation properties,"Spring" sheet saves energy costs during winter time. Polygal Spring sheet means: All year thermal comfort, light & energy saving.

Spring sheet comes in two types:

  • Clear appearance - Translucent
  • Matte - To avoid dazzle
