How to choose an entrance door for a new-build apartment

In short: Choose an entrance door for a new-build flat on five things: security, whether it needs to be fire-rated, insulation, the finish that matches your interior, and the lock. In a white-frame apartment the opening is rarely a standard size, so a made-to-measure steel door fitted correctly matters more than any single feature. Unigon entrance doors are reinforced steel over an aluminium core filled with rock wool, available as EI 30 or EI 60, in RAL and wood-grain finishes, with optional smart locks and a 12-year warranty.

You have the keys to a white-frame flat and a rough opening where the front door should be. Choosing the right entrance door is less about picking a style from a catalogue and more about matching five things to how you actually live — and getting the fit right in an opening that is probably not a standard size.

The short version

Choose your entrance door on five decisions: security, fire rating, insulation, finish, and the lock. Behind all of them sits one practical truth about new-builds — the opening is rarely standard, so a made-to-measure steel door, measured and fitted correctly, matters more than any single headline feature. Get the construction and the fit right first, then tune the finish and the lock to your flat.

1. Security starts with the construction

Security is not a sticker; it is what the door is made of. A Unigon entrance door is a reinforced steel skin over a premium aluminium core, filled with rock wool. That build resists force and gives the leaf its strength, while a multi-point lock spreads the locking points across the door rather than relying on a single bolt. When you compare doors, look past the photo to the construction and the locking — that is what is actually protecting the flat.

2. Decide whether it should be fire-rated

A flat's front door can be part of the building's fire strategy, so this is a real question, not an upgrade. Unigon entrance doors are available as EI 30 and EI 60. But whether yours needs a rating is not your preference to set — the required class for your opening comes from the building's fire-safety design, prepared under the technical regulation approved by Government of Georgia Decree No. 41. If your door schedule or the building management specifies a class, match it; if it is unclear, ask the developer or the fire-safety designer before you order.

3. Insulation: more important in Georgia than people expect

The same rock-wool-filled steel construction that gives security also does the quiet work of insulation. A good entrance door should isolate sound from the corridor, hold thermal comfort between a cold stairwell and a warm flat, and resist humidity — which matters across Georgia and especially near the coast. This is one of the clearest reasons to choose an engineered steel door over a thin stamped one: the insulation comes from the construction, not from an add-on.

4. Finish: match the flat, not the catalogue

In a new-build you are building the interior from scratch, so the door should match it rather than fight it. Unigon offers RAL custom colours and wood-grain or textured finishes, so you can run a dark modern leaf, a warm timber one, or a different look on the corridor side and the flat side. Choose the finish once you know your flooring and wall tones, not before.

5. The lock — and the smart-lock option

The locking package is where convenience meets security. On top of multi-point locking, Unigon entrance doors can take a smart lock, giving keypad or phone access. For a family flat that means no fumbling for keys; if you ever let the flat short-term, keyless access becomes genuinely useful. Decide this up front, because it is part of the door's specification.

Measuring a new-build opening

New-build openings are frequently not standard sizes, and forcing a standard door into a non-standard hole is where problems start. You can take a rough width and height to begin the conversation, but for a made-to-measure door we recommend a measurement visit. Precise measurement lets us produce a door that is cut to your opening — standard or custom — and fitted correctly, which is what makes everything above actually perform. Installation is part of delivering the door, not a separate problem for you to solve.

FAQ

Common questions

Does my apartment front door need to be fire-rated?

It depends on the building. The required fire class for your flat's entrance comes from the building's fire-safety design, prepared under the technical regulation approved by Government of Georgia Decree No. 41. Where a rating is called for, Unigon entrance doors are available as EI 30 and EI 60.

What makes an entrance door secure?

The construction and the locking. A reinforced steel skin over a premium aluminium core filled with rock wool resists force, and a multi-point lock spreads the locking across the leaf. A smart lock can be added on top for convenient, keyless access.

Can I match the door to my interior?

Yes. Unigon offers RAL custom colours and wood-grain or textured finishes, so the door can match a dark modern scheme, a warm timber one, or the corridor side and the flat side differently.

Should I measure the opening myself?

You can take a rough size to start a conversation, but for a made-to-measure door we recommend a measurement visit. New-build openings are often not standard, and a precise fit is what makes the door perform.

Do Unigon entrance doors come with a warranty?

Yes — Unigon entrance doors carry a 12-year warranty. The door is made to measure in standard or custom sizes and supplied with installation.
