Nordwood upgrade

Deeper wood treatment

Factory pressure treatment pushed deeper into every beam. Extra protection against rot, mould and damp, so the Nordic spruce frame stays solid for decades with less upkeep.

  • Deeper penetration than the standard pressure treatment
  • Protects against rot, mould and damp where the frame meets the ground and the glass
  • No change to the look: Gray and Brown finishes stay the same
  • Applied at the factory before your greenhouse ships

Description

Every Nordwood frame is pressure treated. This upgrade takes the same treatment further: the preservative is driven deeper into each beam, including the end grain and the joints where moisture likes to sit. The result is a frame that shrugs off damp winters and wet springs with far less maintenance, and stays structurally sound for decades.

It is done at the factory as part of your greenhouse's production run, so add it to the same order. There is nothing to apply on site.
