The idea of a sunroom has enduring appeal for many homeowners in Westchester, New York.

With Under the Sun Improvements, you’ll have your pick of glass packages and insulation features. These prevent warm air from leaking out while better sealing your space from drafts, cold air, and other winter unpleasantness.
  • Wall widths and knee walls – The dimensions of your walls aren’t just an aesthetic choice. They’ll also play a role in the overall temperature control of your sunroom. Knee walls can be a crucial consideration for an insulated sunroom, especially if you have sloped ceilings. You can always discuss your options with our team, too, making it easier to get walls that suit your style and energy needs.
  • Ceiling fans – When it comes to managing temperatures within any room, a ceiling fans is the unsung hero. That’s especially true for a sunroom.

  • Add soft carpeting – Rugs and carpeting don’t just add visual appeal. They’re also another clever insulation strategy, preventing you from dealing with chilly floors in the winter.
