Security Doors

Alberta understands the need for purposeful yet stylish solutions to architectural openings, which means that you can put your mind at rest that the combination of security and design will suit your building style, function and décor.

Basic Security doors

The paneling:

Alberta allows you to choose from various colours, wood types and trimmings.  There is also a wide range of panel models made by specialist carvers and cabinet makers, who tastefully sculpt the aged walnut, chestnut, oak and cherry wood following the traditional carving and inlay techniques.

The perfect balance: 

The Micron hinges that are fitted as a standard on all double leaf doors make the fitting easy and precise, as well as allowing for the adjustment of the height, depth and width of the door.  Micron hinges can be fitted on some other models as an extra feature.

The hermetic seal:

All models are fitted with a mobile sill, which is indispensable for any security door.  It blocks light and wind and automatically retracts inside the door when opened.

“NO SLAM” system: 

The ‘No Slam’ system keeps the opening and closing of the door entirely under control.  This also makes it easier to prevent damages from blasts of wind or air drafts, and helps to prevent accidents.

The anchoring structure: 

The anchoring structure is made of two steel profiles screwed to one another which surround the door on three sides.  This secures the frame and the sub-frame to the wall, and adds greater resistance to weathering agents thanks to the environmentally friendly polyester powder wrinkled paint finish.

The leaf structure:

  • More secure

The steel core of the leaf is strengthened with vertical Omega reinforcing, which increases the resistance and rigidity of the entire structure.  The welding points transform the body and Omega into a single solid unit. Unhinging is prevented by the hinge grips secured along the hinge edge of the door.

  • More comfort 

The insulating and soundproof panels inside the body provide excellent sound and heat insulation.  Greater air-tightness and silent closure is guaranteed by the PVC or EPDM Hi-Tech seals, positioned throughout the perimeter of the leaf and frame.  The plastic coated steel trim, made from rounded profiles and ribbing on the flat surfaces, improves the look of the leaf and increases its rigidity and security.
