With conservation compliance, Dakea’s conservation roof windows are ideal for installations in conservation areas. They include a beautiful wooden frame that looks natural and simple to suit listed or heritage buildings. They’re affordable, provide good insulation and are highly effective.

Conservation roof window features:

  • Designed with conservation compliance, making them appropriate for conservation areas and heritage buildings.
  • Roof windows with an extra vertical glazing bar on the pane for a vintage look.
  • An affordable roof window which doesn’t compromise on quality. Ideal for “small budget” projects.
  • A simple but efficient way to add light, ventilation and insulation in an attic room or loft conversion. Gain additional living space under one roof at an affordable cost.
  • Dakea Conservation is a center-pivot roof window construction, based on a solid wooden frame.
  • Consists of a ventilation valve and a handle with two additional locking positions for passive ventilation. The window enables comfortable room ventilation to reduce the risk of condensation.

  • Covered with a 20-year guarantee thanks to our commitment to excellent quality.
  • Dakea Conservation roof windows can be installed in all roofing materials, in a roof pitch between 15 to 90 degrees, recessed into slate.
