A.
a)
2 factors to be considered in deciding what types of door is for use in a dwelling house are:

Factors are like durability against exterior or interior use, appearance which requires pattern or painting. And, if applicable, the weight of the door for convenience in operating the doors - especially in industrial buildings - for fire proof and sound proof purposes.

Below is an extract on factors to consider for choosing doors in a dwelling house:

The price of interior and exterior doors will be affected by the material from which they are made, as well as the design. The more elaborately decorated a door is, the more it is likely to cost. Wood exterior doors also cost more than fiberglass or steel doors. Before deciding on the type of door you are going to choose, first consider your budget and what options it allows you.

Look at the Style of Your Home
The exterior doors and interior doors that you choose for your home should also compliment the overall style of your home. If your home is in a pre-war traditional style then you should probably consider wood interior doors, while complex panel designs on interior doors, such as the Italianate arches, Colonial-style split pediment, and narrow Victorian panels should be kept for more modern homes. Your exterior doors, likewise, should match the overall style of the exterior of your home.

The Materials from which Doors Are Made
Doors can be made from a wide variety of materials such as wood, hollow core wood, steel, fiberglass, PVC, glass, or aluminum. Each of these types of materials will have places where they are best used, for example a hollow core wood door can only be used for interior doors as it tends to warp or disintegrate when exposed to the weather; while steel doors are normally used as exterior doors.

The 6 panel door, often called a stile-and-rail door, gives your house instant style. This door has been around for hundreds of years, and is still in wide usage today.

Advantages include:

  • Flexibility. The stile and rail construction provides some "give" to the door, allowing it to expand and contract with changes in humidity. This prevents cracking and splitting. We should note that many of the newer doors do have the 6 panel style, but are actually made of pressed hardboard or MDF. But is expansion/contraction a good thing? Read comments below from an expert on the matter of doors.
  • Great Looks. Because of the "faceting" provided by the stiles, rails, and panels, the six panel door catches the light and produces attractive shadows. This gives the door a 3-D appearance that adds highlights to your room.
  • Variety. Not all 6 panel doors are created equally. You will find panels and stiles with many different dimensions, giving each one a unique look.
