Doors are essential components of any building, serving both functional and aesthetic purposes. They provide privacy, security, insulation, and ventilation while also contributing to the overall architectural style of a property. In construction, the choice of doors depends on the intended use, location, budget, and design preferences.
What is a Door in Construction?
In construction terms, a door is a movable barrier that allows access and closure between two spaces. It is usually fitted within a door frame and can be opened or closed manually or automatically. Doors can be single-leaf or double-leaf, with different materials and hardware to suit residential, commercial, or industrial needs.
A standard door typically consists of:
- Door Leaf – The panel that opens and closes.
- Frame – The structural support fixed to the wall.
- Hinges or Tracks – Mechanisms enabling movement.
- Locks and Handles – For security and operation.
- Threshold – Bottom part, providing sealing and stability.
Functions of Doors in Buildings
Beyond simply allowing passage, doors have multiple functions:
- Security – Protecting against theft, intrusion, and wildlife.
- Privacy – Separating spaces for comfort and confidentiality.
- Climate Control – Helping maintain indoor temperature by preventing heat loss or entry of hot air.
- Sound Control – Minimising noise transfer between rooms.
- Aesthetics – Adding beauty, style, and a sense of welcome.
- Fire Protection – Special fire-rated doors slow the spread of flames and smoke.
Types of Doors Based on Operation
a. Hinged Doors
- Description: Attached to the frame with hinges, swinging open in one direction.
- Use: Common for bedrooms, bathrooms, and main entrances.
- Advantages: Simple design, easy to maintain, durable.
- Limitations: Requires space for the swing arc.
b. Sliding Doors
- Description: Move horizontally along a track, either surface-mounted or within a wall cavity.
- Use: Patios, balconies, conference rooms.
- Advantages: Space-saving, modern look, allows large openings.
- Limitations: Track maintenance is needed to prevent jamming.
c. Folding Doors (Bi-fold or Accordion)
- Description: Multiple panels fold together when opened.
- Use: Partitioning spaces, wardrobes, garden access.
- Advantages: Opens wide, stylish.
- Limitations: More hardware to maintain.
d. Revolving Doors
- Description: Multiple panels rotate around a central shaft.
- Use: Airports, malls, hotels.
- Advantages: Energy efficient, controls air flow.
- Limitations: Expensive, requires skilled installation.
e. Swing Doors
- Description: Hinged to open both inwards and outwards.
- Use: Restaurants, hospitals.
- Advantages: Easy movement in high-traffic areas.
- Limitations: Requires careful placement to avoid obstruction.
f. Automatic Doors
- Description: Operate via sensors or remote systems.
- Use: Commercial entrances, supermarkets.

- Limitations: Higher installation and maintenance cost.
Types of Doors Based on Material
a. Wooden Doors
Description: Made from solid timber or engineered wood.
Advantages: Classic look, high strength, and customisable designs.
Limitations: Can warp or swell if not treated properly.
Ideal Use: Main entrances, interiors, traditional homes.
b. Glass Doors
Description: Made entirely or partially from glass, usually toughened or laminated.
Advantages: Allows natural light, modern appeal.
Limitations: Needs regular cleaning, lower privacy unless frosted.
Ideal Use: Balconies, patios, offices, and partitions.
c. Metal Doors
Description: Constructed from steel or aluminium.
Advantages: Strong, secure, and long-lasting.
Limitations: Can dent, needs anti-rust coating.
Ideal Use: Garages, security entrances, industrial areas.
d. uPVC Doors
Description: Made from unplasticised polyvinyl chloride, a lightweight and durable plastic.
Advantages: Low maintenance, weatherproof, cost-effective.
Limitations: Less strong than solid wood or metal.
Ideal Use: Bathrooms, kitchens, balcony entrances.
e. Composite Doors
Description: Made from a combination of materials such as wood, PVC, foam, and glass-reinforced plastic.
Advantages: Excellent insulation, high strength, low maintenance.
Limitations: More expensive than basic wooden or uPVC doors.
Ideal Use: Main entrances, exterior doors.
f. WPC Doors (Wood-Plastic Composite)
Description: Made from a mix of wood fibres and thermoplastics, offering the look of wood with improved durability.
Advantages:
100% water-resistant — does not swell or rot.
Termite-proof and corrosion-resistant.
Low maintenance — no need for regular painting or polishing.
Eco-friendly — often made from recycled wood and plastic.
Limitations:
Slightly more expensive than regular wooden or uPVC doors.
Limited natural wood grain patterns compared to solid timber.
Ideal Use: Bathrooms, kitchens, main entrances in coastal or humid areas, and outdoor applications.
Types of Doors Based on Location
- Interior Doors – Focus on privacy and aesthetics, usually lighter materials.
- Exterior Doors – Built for security, weather resistance, and insulation.
- Fire Doors – Comply with safety codes, resist fire for 30–120 minutes.
- Garage Doors – May be sectional, rolling, or swing-out, designed for vehicles.
- Security Doors – Reinforced with steel cores or multiple locking systems.
Construction Considerations When Selecting Doors
When specifying doors for a project:
- Load-bearing capacity of frames – For heavy doors.
- Clear opening dimensions – Ensuring compliance with building codes.
- Thermal performance – Especially for exterior doors.
- Acoustic performance – Important in offices and theatres.
- IS Codes (Indian Standards) –
Maintenance Tips for Long-Lasting Doors
- Lubricate hinges, locks, and tracks regularly.
- Clean surfaces to prevent dust build-up and stains.
- For wooden doors, apply varnish or paint every few years.
- Inspect seals and weather strips to maintain insulation.
- Address minor cracks early to prevent larger damage.
Advantages of Selecting the Right Door
- Enhances property value.
- Improves safety and security.
- Increases comfort through sound and temperature control.
- Complements architectural style.
Conclusion🎯
In construction, doors are more than functional barriers – they define the style, security, and comfort of a building. By understanding their types based on operation, material, and location, along with construction codes and maintenance, you can make informed choices that balance durability, safety, and aesthetics. The right door not only protects but also welcomes.
Frequently Asked Questions (FAQs)
Q1: Which door is best for energy efficiency?
Composite and insulated metal doors perform best for thermal control.
Q2: Can sliding doors be used as main entrances?
Yes, with proper locking systems and toughened glass, sliding doors can be secure main entrances.
Q3: How do I choose between solid wood and hollow-core doors?
Solid wood offers better durability and insulation, while hollow-core is lighter and cheaper for interiors.
Q4: What makes a door fire-rated?
Special fire-resistant cores, intumescent seals, and compliance with IS or international fire safety standards.
Q5: Are uPVC doors strong enough for security?
For main entrances, reinforced uPVC with steel cores can provide good security.
