Sigma® OP1

Open panel solution

SIGMA OP1

This wall type is ideal for designs where the air tightness is greater than 3 and minimum U-values are desired.

This system utilises the existing 89mm or 140mm stud options and introduces thermal laminate plasterboard, in combination with mineral or glass fibre insulation between the studs. U-values ranging from 0.44 – 0.16 can be achieved. Sigma® OP1 has the following benefits:

  • Lower cost insulation between studs, with a range of Lambda values
  • Retains 89 or 140mm studs, for manual or crane erection
  • Utilises plasterboard layer for air tightness delivery
  • Limits wall thickness and maintains existing foundation Reduces thermal bridging
  • Services accommodated within studwork and insulation zone
  • Utilises conventional skills and materials
