Internal Door Frame Architrave

The internal door frame architrave is more than just a finishing touch it serves as a functional and decorative element that frames a door and covers the gap between the door frame and the wall. Often overlooked, architraves play a key role in giving a polished, cohesive appearance to interior doors while also hiding uneven edges or construction imperfections. Whether you’re renovating a property or building from scratch, understanding the types, materials, and installation methods of door frame architraves can make a big difference in both style and quality.

What Is an Internal Door Frame Architrave?

An internal door frame architrave is a strip of moulding installed around the frame of an internal door. Its main purpose is to cover the joint where the door frame meets the wall, providing a clean transition between the two surfaces. Architraves also help to protect the edge of the wall from everyday wear and tear, especially in high-traffic areas of the home.

Typically made from wood, MDF, or PVC, architraves come in a wide range of profiles from simple square edges to more decorative styles with curves and detailing. Choosing the right profile depends on your interior theme, be it modern, traditional, or minimalist.

Common Materials for Architraves

The material of your internal door frame architrave impacts durability, ease of installation, and appearance. Here are some of the most common options:

1. Solid Wood

Timber architraves are known for their strength and natural look. They can be stained or painted to match various interior styles. Popular wood types include oak, pine, and hardwoods like ash or beech. Though slightly more expensive, solid wood offers longevity and a premium finish.

2. MDF (Medium-Density Fibreboard)

MDF is a widely used alternative due to its affordability and versatility. It’s easy to cut and paint, making it ideal for DIY projects. Moisture-resistant MDF is also available for areas with higher humidity. Keep in mind that MDF is not as strong as wood and may dent or chip more easily if handled roughly.

3. PVC or uPVC

Plastic architraves are moisture-resistant and ideal for use in bathrooms or utility rooms. They require little maintenance and are often pre-finished, but they lack the aesthetic warmth of wood or the customizability of MDF.

Types of Architrave Profiles

When selecting an architrave, the profile or shape of the moulding determines the visual impact. Here are a few popular styles:

• Bullnose: A smooth, rounded edge that suits modern interiors.
• Torus: Features a large curved section commonly used in traditional homes.
• Ogee: A decorative profile with sweeping curves, often found in classic interiors.
• Square Edge: Clean and contemporary, ideal for minimalist designs.
• Lamb’s Tongue: Offers subtle detailing with an elegant, traditional look.

Standard Dimensions of Door Frame Architraves

Architraves come in various widths and thicknesses, but common sizes include:

• Width: 60mm, 70mm, or 90mm
• Thickness: 15mm to 25mm
• Length: Typically sold in 2.4m or 3.0m lengths for convenience

The size you choose depends on the proportions of your room and doors. Larger rooms with high ceilings can handle wider architraves, while compact spaces benefit from slimmer, more subtle profiles.

How to Install an Internal Door Frame Architrave

Installing an architrave around an internal door is a manageable task, even for beginners, with a few basic tools. It usually consists of two vertical side pieces (called legs) and a horizontal top piece (the head). Here’s a general step-by-step guide:

1. Measure and Cut

Measure the height from the floor to the top of the door frame for the side legs. Cut each piece using a mitre saw at a 45-degree angle at the top end to create a clean corner joint with the head piece.

Next, measure the width between the top angles of the two side pieces to cut the head. Mitre both ends at 45 degrees to complete the frame.

2. Dry Fit the Pieces

Before securing anything, do a dry fit to check that all pieces align properly. Adjust any angles or lengths as needed to achieve a seamless fit.

3. Fix the Architrave in Place

Apply a strong wood adhesive or grab adhesive to the back of the architrave. Position the side legs first, pressing them firmly into place. Follow with the head piece at the top.

For added security, use finishing nails or a nail gun to fix the pieces to the wall. Countersink the nails slightly and fill the holes with wood filler for a smooth finish.

4. Sand and Paint

Once the adhesive and filler are dry, lightly sand the joints and nail holes. Apply primer and paint or wood stain to match your interior décor. Use a small brush for precision around edges and corners.

Tips for a Professional Finish

• Maintain consistent margins: Leave an even gap usually 5-10mm between the architrave and the door frame for a symmetrical look.
• Use a spirit level: Ensure the architrave pieces are straight, especially on older walls that may not be perfectly plumb.
• Caulk the edges: Fill any gaps between the wall and architrave with decorators’ caulk for a clean, seamless appearance.
• Paint before fitting: Pre-painting the architrave can save time and result in a cleaner application, especially in tight spaces.

Choosing Architrave Styles to Match Interior Themes

Architraves may seem like a small detail, but they significantly influence a room’s visual appeal. Here’s how to match them with different interior styles:

Modern Homes

Opt for square-edged or bullnose profiles in white or light grey finishes. Keep lines simple and sharp, avoiding unnecessary detailing. Slimmer profiles work best for a minimalist effect.

Traditional Interiors

Go for torus or ogee profiles in natural wood finishes or warm painted tones. Pair with decorative skirting boards and panel doors for a cohesive period look.

Contemporary Designs

Consider contrasting colours or matte finishes. Mix materials such as painted MDF with metal door handles to create a dynamic look.

An internal door frame architrave is a subtle yet impactful architectural detail that enhances the transition between rooms and refines the overall aesthetic. Whether you’re working with a new build or updating a period home, selecting the right architrave material and profile can make all the difference. With proper installation, finish, and alignment, architraves provide long-lasting beauty and function. Don’t underestimate the visual power of this often-overlooked feature when chosen thoughtfully, it adds the perfect finishing touch to any interior space.
