Aluminium offers everything!
Because aluminium doors are superior to plastic or timber doors in many ways. The advantages:

High thermal insulation
High security
High acoustic insulation

No follow-up painting necessary

Aluminium doors look new for years, and also offer you a large variety of options in regards to technical equipment and design.

ThermoSafe aluminium entrance door
If you want high thermal insulation and security for your home, we recommend our ThermoSafe door. With a 73 mm thick door leaf and the standard 5-point security lock, you not only save energy, but also protect your home from break-ins and keep out noise.

ThermoCarbon aluminium entrance door
Do you value excellent thermal insulation and the highest security? Then our ThermoCarbon entrance door with a UD value of up to 0.47 W/(m2·K) is the right choice for you. The door leaf is 100 mm thick and the leaf profile is reinforced with carbon glass-fibre. This means ThermoCarbon doors are a great choice for low-energy houses! And with regards to security, the ThermoCarbon meets the highest demands thanks to its 9-point security lock.

Exactly the door you want
We offer many options, so you are certain to find the perfect door to fit your home. Just about all the entrance door styles have optional glazings and colours of your choice. Side elements and/or transom lights are also possible.

Door leaf without visible leaf profile

  • Door leaf without visible leaf profile
  • The ThermoSafe and ThermoCarbon entrance doors give you an exquisite and elegant reception. The shapely door leaf with its solid interior and exterior and leaf profile on the inside fulfils the highest design requirements. The interior view harmonises perfectly with the residential internal doors of your home.

Highest thermal insulation

  • Highest thermal insulation
  • ThermoSafe and ThermoCarbon entrance doors are the new generation of high-insulation entrance doors. ThermoSafe fulfils all the requirements of a low-energy house with excellent thermal values and triple thermal insulated glazing. ThermoCarbon entrance doors up the ante: with flush-fitting, 100-mm-thick door leaf, thermal break thanks to carbon glass-fibre, standard triple or quadruple thermal insulated glazing and triple sealing, they also provide maximum thermal insulation for low-energy house construction.
  • ThermoSafe UD-value of up to 0.8 W/ (m²·K)*
  • ThermoCarbon UD-value of up to 0.47 W/ (m²·K)*
  • Door size 1250 × 2200 mm (the UD-value is dependent on the door size)

Break-in-resistant locking

  • Break-in-resistant locking
  • Our ThermoSafe and ThermoCarbon entrance doors set new standards for security. All doors are equipped with multiple-point locking as standard. This means the hinge side is better protected against forced opening. You can also opt for ThermoSafe and ThermoCarbon entrance doors, side elements and transom lights with break-in resistant RC features – giving you and your family more security.

Safe glazing

  • Safe glazing
  • Accident prevention and break-in protection come first: ThermoSafe and ThermoCarbon entrance doors fulfil the highest demands of design and security. The 8-mm-thick laminated safety glass on the interior and exterior of the insulated glazing provides maximum security. In case of breakage, the glass splinters are bound and stay adhered to the plastic film on the inside, ensuring that there is no danger of being injured by the shards. Furthermore, the laminated safety glass offers better protection against burglars, because it makes reaching through more difficult. Thanks to a highly insulated edge compound with thermal break (warm edge), the glazing offers high thermal insulation for effective energy saving and high acoustic insulation for more peaceful living conditions.
