How to start choosing break in resistant entry door for your home?

At the very beginning, you need to determine the level of risk of burglary. If there are such cases in your area, this is a sign that you need a door with  RC-3 class burglary or higher. If the risk of burglary in your area is relatively low, RC-2 door is sufficient. The frame, regardless of the security class of the entrance door, must be made of steel or extruded aluminum alloy profile and have at least 3 hinges. Also take care of strong locks. They will be the first obstacle a thief will face.

Here you can find doors designed for residential home exposed to weather conditions such as temperature, sun, rainfall and wind. The task of any exterior door is to protect from adverse weather conditions and ensure the safety of people and their property.


GERDA burglar-proof doors meet and even exceed all the required standards for exterior doors with increased burglary resistance.

How to use GERDA entrance doors correctly?

If your concern is forced entry resistance, you should consider the door installation with out-swing opening direction. This way the door can't be kicked in. Solid (no glass) door design can increase the door resistance to forced entry because of consistent evenly distributed internal structure of the door sash. However, our glass inserts are break in resistant since we use triple glass with 6 mm laminated (car windshield quality) exterior glass.
