\"PP<\/a><\/div>\n

Doors and frames are damaged by two things: swings that hit a stop or a wall, and trolleys that clip the frame on the way through. Both happen after the door is hung, which is exactly when replacement is most disruptive. This article looks at protecting doorsets during fit-out. The focus is frame corners, door faces and protection that does not stop the door working.<\/p>\n

Doorsets are damaged after they are hung<\/h2>\n

A doorset is at risk from the moment it is hung until handover, because that is when the building is busiest. A chipped frame corner or a dented door face usually means replacement rather than repair, and rehanging delays other trades.<\/p>\n

The protection therefore has to work while the door is in use. A rigid PP honeycomb protection board<\/a><\/a> can be cut to the leaf and frame and secured without blocking operation, which is not possible with a wrapped film that catches at the hinge.<\/p>\n

A felt or fleece facing protects finished or veneered door faces from abrasion at the point where materials brush past.<\/p>\n

Thickness choices from 2 mm to 12 mm<\/h2>\n

On doorsets thickness is constrained by clearance: too thick and the door will not close or will bind at the frame. Within the 2 mm to 12 mm range, the thinner end is usually correct for leaves, with thicker boards reserved for frame corners and threshold protection.<\/p>\n

Where trolleys pass through regularly, protect the frame rather than the leaf, because frame corners take the impact and are the hardest part to repair invisibly.<\/p>\n

Protecting the leaf, the frame and the threshold<\/h2>\n

Cover the lower part of the leaf where trolleys and materials contact it, and the frame corners where impacts land. Leave hardware, closers and seals accessible so the door still functions.<\/p>\n

Protect thresholds and sills separately, because they take wheeled loads directly. A small rigid panel over the threshold prevents the crushed edges that are otherwise very visible at handover.<\/p>\n

Check the door still latches and closes after protection is fitted. A doorset that has been protected into non-compliance is a fire and security problem, not just an inconvenience.<\/p>\n

How honeycomb board compares with film, cardboard and ply<\/h2>\n

Protective films work on flat door faces but tear at edges and handles, and they can leave residue if left beyond their stated removal period.<\/p>\n

Cardboard is cheap and easy but crushes, absorbs water at thresholds and looks poor in a client-facing area. Plywood protects but is heavy to fix to a leaf and changes the door’s balance and swing.<\/p>\n

A PP honeycomb board is light, cuttable and re-usable, and it protects frame corners without adding significant weight to the leaf. That balance is why it suits doorsets in live buildings.<\/p>\n

A practical trial plan for doorsets<\/h2>\n

Protect the doors on one floor and leave a comparable floor unprotected. Record damage at each inspection, separating leaf damage from frame damage, since the two have different causes.<\/p>\n

Run a trolley test through a protected doorway with the heaviest load that will pass, then check the frame corners and threshold.<\/p>\n

Confirm every protected door still closes and latches, and record that check, because a door that fails to latch is a compliance issue regardless of how good the protection is.<\/p>\n

What to include in a protection board enquiry<\/h2>\n

State the doorset type, whether it is fire rated, the finish, and what passes through the opening. Ask for the recommended thickness, facing and panel size, and confirm that protection will not affect closing or latching.<\/p>\n

Ask for guidance on frame corner detailing and threshold protection, and about custom sizes to reduce cutting on repeated door sizes.<\/p>\n

Final takeaway<\/h3>\n

Protect the frame corners and threshold rather than the whole leaf, keep clearance so the door still latches, and use a soft facing on finished faces.<\/p>","protected":false},"excerpt":{"rendered":"
