For single and double door configurations

Subtract 2" from the rough opening width and 1 1/4" from the height. This will determine the door slab size.

1

Let's imagine that we have measured the width of the rough opening and it equals 35"

In order to determine the width of the door slab, we first of all need to subtract 2" from the width of the opening. So where do these 2 inches actually come from?

2

The standard thickness of Doordesignlab jamb is 3/4".
3/4" + 3/4" = 1 1/2" is the total thickness of 2 jambs.
And we leave the rest of the space (1/2") as technological gaps to be filled in construction foam.
So this forms the 2 inches' width that needs to be subtracted from the overall width of the opening.

3

35" - 2" = 33"
Now we need to determine which standard width is suitable for the 33" wide opening.
This is obviously 32".
And the remaining space will be filled width construction foam and covered with prefinished casings.

Standard width of Doordesignlab casings is 3 1/2"

For barn, magic, bi-fold, bypass and pocket door systems

Please refer to the manuals provided by the hardware manufacturers.

A standard US rough opening consists of:

One of the fundamental elements here is a wall stud.
Studs are traditionally made of wood, usually 2"×4" or 2"×6" dimensional lumber and typically placed 16 inches (406 mm) from each other's center, but sometimes also at 12 inches (305 mm) or 24 inches (610 mm). The wood needs to be dry when used otherwise problems may occur as the studs shrink and twist when they dry out.

Considering this fact, the actual sizes of the framing studs are:

The standard 2"×4" or 2"×6" wall assembly is as follows:

Studs with insulation filling in between and a layer of drywall from both sides of the construction.The drywall is normally 5/8’’ thick. Sometimes several layers of drywall are used.This knowledge is important whenever you want to measure the thickness of the wall because it actually defines whether you need an extension or not.

See the picture below in order to learn how to accurately measure the size of the rough opening.
First, measure the width between the studs of the doorway three times (picture 1) and record the smallest of the three measurements.
Second, measure the height on both sides (picture 2) and record the smallest measurement. Congratulations! You have determined the width and the height of the rough opening.

A door schedule is a tabulation, usually on a blueprint or in specifications, which list all doors required for a job, indicating sizes, types, locations, and special requirements.

A door schedule is the basis for providing a detailed and accurate quote to a customer and usually contains the following information:

  • Door types and functions
  • Door locations
  • Door materials and finishes
  • Door sizes
  • Number of doors
  • Configurations (swing, bypass, pocket etc.)
  • Types of hardware needed (handles? concealed or plain bearing hinges? tracks?)
  • Swing directions
  • Lockset functions (passage, privacy or keyed)
  • Fire ratings
  • Other requirements

The quality solid pine frame is the basis of a strong and durable construction of Doordesignlab doors. The width of the frame is 1 ½’’. It undergoes several drying processes in special heating cameras which keeps the wood humidity level within 8%. The frame thickness can vary from 1 9/16’’ to 1 ¾’’ depending on the door model.
Doordesignlab doors may come with 3 types of core depending on the model, which are:

  • Solid wood core (natural hardwood filling or MDF)
  • Honey-comb core (filling is honey comb cells, which grant additional lightness to the door, thus protecting the hinges from extra load and still retaining high noise reduction and thermal insulation qualities)
  • Smart core (technologically advanced, eco-friendly filling, which is a high density natural wood fiber. This type of filling provides additional durability, noise reduction and thermal insulation.)

We use high quality solid pine in production of our frames which makes them rigid and durable enough to hold a heavy 8’ solid core door slab.

Absolutely! You can use any handle with our doors; however keep in mind that we bore for 1 3/8” backsets! If you need us to make a 1 3/4” backset, let us know when you are placing your order.

Doordesignlab doors can be fitted with several types of hinges:

1) Plain bearing hinges – quite old-fashioned and plain, as it comes from their name.

2) OTLAV 3D-adjustable concealed hinges

With the Italian made concealed hinges, door opens smoothly and precisely up to 180°. The hinge blends seamlessly with the slab and the frame for a markedly elegant door design solution. Thanks to the symmetric milling, the hinge is reversible and allows choosing the door swing directly on the job site. It is 3 ways adjustable (XYZ) which is definitely a strong competitive advantage. The decorative cover plates conceal the adjustment screws for elegance when the door is open.
Weight capacity is 132 lbs. per 2 hinges. Resource is 200 000 openings.

Doordesignlab door sizes are fully compliant with the US market standards. Regular stock sizes are:
W: 18’’,24’’,28’’,30’’,32’’,36’’
H: 80’’, 92 ½’’
Only the Arvika model has the height of 80’’, 84’’ and 96’’.
Basically, the largest possible sizes of Doordesignlab custom door slabs are:

Type of finish
Width Height
Veneer coated doors
37 3/4
92 1/2
Polypropylene coated doors
39 3/8

Three Otlav or three plain bearing hinges.

Absolutely! However, it has to be placed as a special order and the lead-time will be 14 - 16 weeks (12 weeks with air expedited shipping) + shipping from Doordesignlab warehouse.

A jamb extension does precisely what the name suggests – it's a board that fills the depth of the wall space from the inside face of the door frame to the face of the wall and thus widens the frame. So if the wall thickness is greater than the standard jamb width, extensions must be used.
Doordesignlab jamb extensions are typically made of MDF and create a clean edge for the casing trim to be nailed to or inserted if this is a telescopic L-casing.
With the help of extensions Doordesignlab frames can cover walls 4 7/8” to 6 7/8” thick.

You can purchase Doordesignlab slabs only. However, we strongly recommend that you equip the door unit with our matching jambs and casings, coated with the same finishes as the door slab.
We use high quality solid pine in production of our jambs, which makes them rigid and durable enough to hold even a heavy 8’ solid core door slab.
Doordesignlab casings are made of MDF board and with the use of our telescopic L-shaped casings the thickness of the wall covered by the door frame can be extended to 4 7/8”. No other extensions needed.

Glassed Doordesignlab doors are fitted with white or dark frosted glass of Czech production. For most glassed models, we apply special tempered glass 1/6’’ – 1/4’’ thick. Besides high firmness, it is also safe to use.
Should be damaged, such glass shatters into small, smooth surfaced pellets, excluding the possibility of injury.

Doordesignlab provides a full range of options when it comes to the choice of a door configuration.

However, we strongly recommend consulting with one of our experts before placing an order, simply because the construction of our doors is different.
