Planning a Home Extension? Here Are the Essential Windows, Doors, and Roof Glazing Options
Extending your home is an exciting opportunity to add space, style, and value to your property. Whether you’re building a new kitchen-diner, adding a rear extension, or converting a loft, the right glazing and door products can make all the difference.
In this guide, we’ll walk you through some of the most essential window, door, and roof glazing options to consider when planning your extension.
1. Roof Lanterns
Roof lanterns are a show-stopping addition to flat-roof extensions. These architectural features flood your space with natural light and create a dramatic, open feel.
Benefits
- Maximises daylight
- Adds visual height to ceilings
- Improves ventilation (when opening options are included)
- Ideal for kitchens, dining areas, and garden rooms
According to the Energy Saving Trust, using natural light sources like roof lanterns can help reduce reliance on artificial lighting and lower overall energy consumption.
2. Flat Glass Rooflights
If you prefer clean, modern lines, flat glass rooflights offer a sleek alternative to roof lanterns. These units sit flush with the roofline, offering a contemporary look without compromising on natural light.
Key Features
- Frameless internal finish
- Fixed or opening options available
- Double or triple glazing for improved energy efficiency
Flat glass rooflights are perfect for minimalist interiors or areas where planning restrictions apply.
3. Bifold Doors
Bifold doors are a top choice for rear extensions, allowing for a wide and seamless opening between your indoor and outdoor spaces.
Advantages
- Fold away neatly to open the entire wall
- Modern, stylish appearance
- Customisable configurations and colours
- Ideal for patios with level thresholds
Bifold doors are especially popular in kitchen-diner extensions and garden rooms where indoor-outdoor living is a priority.
4. Exterior Sliding Doors
An alternative to bifold systems, exterior sliding doors offer larger uninterrupted glass panels for panoramic garden views.
Benefits
- Slim sightlines for maximum visibility
- Smooth and easy operation
- Takes up less internal space than folding doors
- Available in durable aluminium frames
Sliding doors are ideal for contemporary homes and large extension openings.
5. Fakro Roof Windows
If your extension includes a pitched roof or loft conversion, Fakro roof windows are an excellent way to bring natural light into upper spaces.
Features
- Wide range of sizes and opening styles
- Top-hung or centre-pivot operation
- Triple-glazed options available for enhanced energy efficiency
These windows work perfectly in loft rooms, stairwells, and attic conversions where vertical windows are not possible.
6. Composite Front Doors
Your extension project might also include a new or relocated entrance. Composite doors combine security, insulation, and visual appeal.
Benefits
- Strong timber core with durable GRP outer skin
- Excellent thermal performance
- Low maintenance
- Wide range of colours and design styles
Composite doors provide a secure and stylish welcome to your home.
7. PVC and Aluminium Windows
Choosing the right windows for your extension affects energy efficiency, sound insulation, and the overall look of your property.
PVC Windows
- Cost-effective option
- Good thermal insulation
- Low maintenance
Aluminium Windows
- Ultra-slim frames

- Highly durable and recyclable
Both options can also be fitted with double or triple glazing to improve insulation and reduce outside noise.
