Description

Pilkington Optitherm™ S1 Plus offers ultra-low-emissivity and achieves a Ug-value of only 1.0 W/m2K when incorporated in a double glazed IGU.


It is a single stock product hence can be used for annealed, laminated and toughened applications being toughened after processing.


Pilkington Optitherm™ S1 Plus combines superior light transmittance with a highly neutral colour. It is the ultimate in thermal insulation and should be specified for any situation where excessive heat loss is a concern.


Features and benefits:

  • Ultra-low Ug-value 1.0 W/m²K in a double glazed IGU, in accordance with EN 673.
  • Ug values as low as 0.5 in triple IGUs.
  • Energy efficient way to reduce heating bills and environmental impact through reduced CO2 emissions.
  • Highly neutral appearance in transmission and reflection.
  • Suitable for both domestic and commercial applications including refurbishment and new build.
  • Available in a range of sizes and thicknesses for various applications.
  • Available in combination with Pilkington Optilam™ and Pilkington Optiphon™ for impact resistance, increased security or improved noise reduction.
  • It can be combined with other products from our range to provide additional benefits such as safety, security, noise control, self-cleaning and solar control.
