How Carlson Doors Are Constructed

Carlson's exterior doors have many safety features to protect your home, for example, safety hinges with a mechanism that prevents your door from being lifted out of its frame. In addition, the hinges are secured to the frame with a metal mounting plate. They also have a security unit, which protects against attempts to forcibly open the lock. The lock is equipped with a hook bolt that connects the door with the door frame and makes it virtually impossible to break apart the door and frame. Most Carlson exterior doors have three hinges.


01 Frame: The frame is made of solid pine and the dimensions are 40 x 105 mm. Teak doors are teak stained or solid framed, oak doors have a solid oak frame.

02 Threshold: Thresholds made of hardwoods normally have a protective aluminum strip. The profile of a threshold complies to disability standards where applicable.

03: Board/veneer: The inside and the outside of the door are covered with a moisture-resistant HDF board or glued veneer if the door is oak, pine or teak.

04: Aluminum sheet: The inner and outer layers of the door have a moisture repellant and stabilizing aluminum sheet which is 0.5 mm thick.

05: Door frame: The door frame is made of solid pine or oak.

06: Insulation: Environmentally-friendly polystyrene foam insulation. Fire doors are insulated using rock wool.

07 See point 4.

08 See point 3.

09 Decoration/Surface treatment: Decoration using sheet, strips and profiling on the outside of the door. Several surface treatment materials are available, for example, paint, teak or pine.

10 Glass: Mounting of a triple pane insulating window unit. The panes are available in several styles.

11: Lock: Most exterior doors are supplied with security classified locks which comply to relevant standards.

12: Frame screw: Pre-drilled frame to accommodate frame screws.

13: Hinge: Adjustable inserted barrel hinges with rear edge security. The hinge is secured in the frame with a fitting plate.

14 Security plate: Security plate with adjusting screws and a manually adjustable cover plate.

15 Sealing strip: Sealing strip made from long lasting rubber.


The size of a door is always stated in module (M) size. This measurement is not the exact size of the door frame. It is the size of the opening in the wall where the door will be placed. For a door with module size 9 x 21 (width by height), you will need an opening in the wall of at least 900 x 2100 mm. The actual exterior door frame dimensions are 10 mm smaller in width and height in order to leave room for insulating materials and adjustment. The size of a module can also be expressed as including insulation and mounting fittings.


When replacing an exterior door, it is normal practice to replace both the door and the frame. The size of the door should be related to the size of the opening in the wall. It is not enough to measure the size of the door only. Contact your builder/carpenter if you are unsure. For an accurate measurement of the door you will need to remove strips and insulation around the frame of your old door. Measure the opening in the wall. Subtract 20 mm from the width and height of your dimensions. In this way, you get the maximum width and height your new door unit can have. Choose a suitable new door module.


When looking from the outside, decide if your door should be right or left hung.
