What Makes ADLO Exterior Doors Unique?

Door dimensions & custom solutions
Doors can be manufactured in any size – tailor-made or in standard dimensions of 80/197 cm or 90/197 cm. The maximum door size is 105 x 250 cm. For larger openings, a transom window can be used.
Revolutionary thermal insulation construction
The doors feature a new revolutionary thermal insulation design that minimizes heat loss – with a heat transfer coefficient of U=0.9 W/m²K. The lower the coefficient, the better the insulation performance. Only frost-resistant, rain-resistant, and moisture-resistant materials are used in production. Anti-corrosion resistance is guaranteed by electrolytic galvanization of the steel structure.
ADLO Termo frame and security threshold
The special ADLO Termo frame breaks the thermal bridge and prevents condensation on the inside of the frame. The integrated security threshold increases the overall strength and safety of the door.
Protection against water leakage
Prevention of rainwater leakage is ensured by double sealing around the perimeter of the door and a special security threshold. The threshold prevents water from penetrating under the door. It is made of stainless steel, resistant not only to weather conditions but also to mechanical damage, and remains visible even when the door is closed.

The sidelight brings natural light into the space behind the door, filling and closing the wall opening, creating a clean and elegant look with the door set. The unique modular system allows for countless combinations and shapes, either together with the doors or separately.
Thermal insulation properties of the sidelight
The sidelight is fitted with special insulated Termo triple glazing with a heat transfer coefficient of U = 0.6 W/m²K. It has a double thermal frame with insulation that prevents condensation on the inside.
Sidelight security
The sidelight is made with certified armored glass, resistant to burglary in security classes RC2 and RC3 according to ENV 1627 – offering “very high protection.” Both the anchoring of the glass into the frame and the fixing of the frame into the wall are certified. The glass is multilayered: the thicker it is (more layers), the higher its security class.
The sidelight design matches your door
You can choose the transparency and color of the glass. For solid sidelights, various colors and finishes are available, customized to match the design of your door.

Long lifespan and weather resistance
Durability is ensured by double-sided electrolytic galvanization, phosphating, and powder coating baked at high temperature. The longevity of such a sidelight is incomparably higher compared to plastic or wooden alternatives.

Glazed Front Entrance Doors
ADLO Termo triple glazing is used in production, providing high thermal insulation with a U-value of 0.6 W/m²K – suitable even for low-energy buildings. The innovative glass anchoring system with a broken thermal bridge prevents condensation of air humidity.
Certified armored safety glass
Applied to doors requiring higher security levels (RC2, RC3, RC4). This is multi-layered glass: the thicker it is (more layers), the higher the security class. When choosing your design, you can also select different glass finishes for the inside and outside.

Double exterior Termo doors offer the same freedom of choice as single doors – in surface finish, glazing options, and colors. They can also be combined with sidelights, while maintaining the same level of thermal insulation and security according to your needs. Every ADLO door is unique and always custom-made. The maximum size for double doors is 210 x 250 cm + frame.
Double doors can be certified for: Security, Fire Resistance, Sound Insulation, and Thermal Insulation. Installation of double entrance doors is possible only with a new ADLO frame.

Smart Door Systems
Door with fingerprint access
Keyless entry through a biometric lock is one of the most secure door opening systems on the market. It is convenient and reliable. You can unlock and lock your security door at all locking points simply by placing your finger or via a smartphone app. The option to open or close the door with a traditional key remains available.
Smart doors: Live Wifi Dual
The door actively protects itself and the entrance area 24/7 – day and night – with a viewing angle of up to 180 degrees. Through your smartphone, you receive real-time video and audio notifications about anyone at your door. You can communicate instantly, no matter where you are – while the visitor has no idea of your location.
