Frequently asked questions

How long will ADLO doors last?

ADLO doors are designed to last for generations. With proper care and regular servicing, they will function perfectly even after 50 years. Throughout their entire lifespan, we guarantee the availability of service and spare parts.

Can I customize the doors to my personal taste?

Yes. We offer more than 1,000 combinations of surface finishes, colors, and accessories – from handles and peepholes to smart electronic locks. We tailor the doors to both the facade and interior so they match your style and security requirements.

Are your doors truly security doors?

Yes. All ADLO doors are certified according to European security classes RC1 to RC5. It’s not just about the lock – the key elements are the durable construction, solid anchoring, and a sophisticated system of protective components against forced entry, drilling, and breaking.

Who manufactures and installs the doors?

We manufacture our doors in Slovakia, where the ADLO brand originates. We control the entire process – from development and production to installation and service. This allows us to guarantee the quality of every detail.

How long does delivery and installation take?

The delivery time depends on the level of customization, but installation typically takes place within 3–5 weeks after measurement. The installation itself takes only a few hours and includes user training so you can safely use the doors from day one.

What kind of service do you offer after installation?

We remain at your disposal even after installation. We offer long-term post-warranty service, regular inspections, and repairs without the need to replace the doors. We stay in touch with many customers for decades.

Can I see your doors in person?

Yes. We have company-owned and partner showrooms throughout Slovakia. Visit us and consult with our specialists, who will explain everything ADLO security doors can do. Or contact us and we’ll arrange a visit from our sales representative.

How much do ADLO security doors cost?

The price depends on the specific model, equipment, installation, and transport, as well as any custom modifications (for example based on the size of the door opening). For reference, the basic Jubeo model in RC1 security class starts from €680 excl. VAT. Additional costs include the security cylinder, hardware, accessories, frame, threshold, installation, and transport. The best option is to visit one of our stores or arrange a consultation. Our experts will prepare a tailored price offer for you.

What makes ADLO doors different from standard entrance doors?

Unlike standard doors, ADLO doors are not just wooden panels with hardware. Each ADLO model has its own steel and composite construction, tested burglary resistance, and dozens of technical details designed to protect your home.

What is the difference between security doors for houses and apartments?

House doors must withstand not only burglary attempts but also changing weather conditions – frost, wind, rain, and sun. Compared to apartment doors, thermal insulation, sealing, and outdoor suitability are essential. All ADLO house doors are designed for these conditions.

Are security doors suitable for renovating an older house?

Yes. All doors are custom-made, so we can adapt them to any construction situation – including non-standard openings or replicas of historical doors. Our technicians carefully measure everything and prepare a tailor-made solution.

Are ADLO doors suitable for new builds?

Absolutely. In new buildings, we focus on maximum security as well as harmony with modern architecture. Thanks to a wide range of designs, finishes, and colors, the doors fit seamlessly into any architectural style.

How do the doors protect against cold, wind, and street noise?

ADLO house security doors offer excellent thermal and acoustic insulation. The heat transfer coefficient U reaches a value of 1, placing ADLO doors among the top products on the market. They can reduce noise by up to 42 dB, keeping warmth inside and noise outside.

What features should high-quality apartment entrance doors have?

In addition to high burglary resistance, they should offer good sound and fire protection. The security cylinder, number of locking points, and overall structural strength are also crucial. ADLO doors meet all these requirements.

Are ADLO apartment doors fire-resistant?

Yes. All our apartment door models are certified for fire and smoke resistance in class E30. They can prevent the spread of fire and smoke for at least 30 minutes, protecting you and other residents.

How long does the installation of ADLO security doors take?

The installation usually takes half a day. We start in the morning and finish by early afternoon, including fitting, adjustment, and cleaning.

What design options do ADLO doors offer?

We offer over 1,000 combinations of surfaces, decors, and colors – from wood finishes to RAL colors, smooth and panel designs. You can choose a look that matches your interior and exterior perfectly.

How often do you recommend servicing ADLO doors?

We recommend servicing every two years, or more frequently for doors with heavy use. Regular maintenance ensures long-lasting insulation and security performance.
