They value calls-to-action from these communities to guide and inform their decision-making in product development and daily operations.

They remain steadfastly focused on success in two key pillars of performance:

Comfort Performance

  • Utilize technology that results in the highest thermal efficiency – think “warm to the touch on a cold winter night”
  • Provide super-insulating products which dramatically reduce the amount of air volume which passes through the barrier
  • Embrace “directional tuning” as a design philosophy to allow customized performance optimization based on building architecture, use, orientation, climate and elevation
  • Construct products with high quality, durable materials which deliver comfort and performance in all seasons
  • Use non-toxic, non-off gassing materials wherever possible

Business Performance

  • Establish trustworthy relationships with customers through clear, thoughtful, unbiased communication and guidance throughout the selection and purchasing process
  • Deliver products on-time and on-budget
  • Provide an immaculate attention to detail which focuses on quality and craftsmanship throughout the manufacturing process
  • Publish only third-party validated/certified performance data
  • Establish quality control programs that consistently surpass requirements set forth by these third party agencies
  • Integrate innovative and advanced technology into all our product offerings
  • Demand the same high quality standards from our suppliers as those to which we hold ourselves accountable
