01

Prepare openings and support conditions

Make the opening fit the product before the product arrives.

  • Check opening size, squareness, level, support and fixing zones.
  • Repair weak edges and confirm sill slope or water path.
  • Verify that waterproofing, facade and interior finish thicknesses align.

Punto de control: Window and door installation should not start until openings are measured and corrected.

02

Install frames, flashings and weather seals

Close the water path at each opening and edge.

  • Fix frames with correct packers, anchors and movement allowance.
  • Install sill flashings, drip edges, tapes and perimeter sealant.
  • Protect exposed joints until facade and interior returns are complete.

Punto de control: Do not cover perimeter joints until fixings, packers, flashing and sealant backing are inspected.

03

Test water path and close interfaces

Confirm the envelope works as a system before finishing returns.

  • Check drainage path at sills, thresholds and facade interfaces.
  • Inspect moisture bridge risks around plinths and exposed edges.
  • Record completed details before interior and exterior finishes hide them.

Punto de control: Interior finishing should wait until envelope interfaces are weather-tight and recorded.
