Installation Tips for Internal Composite Doors

• Acclimatise first: Store flat and supported in a dry, ventilated area before fitting.
• Measure twice: Check frame squareness, hinge positions, and latch height across your batch.
• Trim within limits: Follow the product’s guidance on maximum trimming; avoid cutting into the structural core.
• Seal all edges: After trimming and before final hanging, seal/paint every cut edge to protect the core from moisture.
• Use quality hardware: Hinge count and screws must suit the door weight; FD30 doors require certified hardware and correct clearances.
• Final checks: Confirm latch performance, even gaps, smooth swing and that any glazed units face the correct way per manufacturer notes.
