Investing in double glazed doors can significantly enhance the comfort, security, and energy efficiency of your home. However, understanding the factors that influence their pricing is crucial for making informed decisions. In this blog post, we explore the key factors that affect the cost of double glazed doors, helping you navigate your options and choose the best fit for your budget and needs.

Double glazed Doors

1. Materials

The choice of materials plays a pivotal role in determining the cost and performance of double glazed doors:

  • UPVC (Unplasticized Polyvinyl Chloride): UPVC doors are cost-effective and low-maintenance. They offer good insulation properties and come in a variety of colors and finishes.

  • Aluminium: Aluminium doors are durable, lightweight, and sleek. They are more expensive than UPVC but offer a modern aesthetic and robust security features.

  • Timber: Timber doors provide a classic, natural look and excellent insulation. They are typically the most expensive option due to the high-quality materials and craftsmanship involved.

2. Styles and Designs

The style and design of double glazed doors can vary widely, influencing their cost:

  • Standard vs. Custom Designs: Custom-designed doors or non-standard sizes may incur higher costs due to the additional labor and materials required.

  • Panel Configuration: Doors with more panels or intricate designs may cost more than simpler, single-panel designs.

3. Sizes

The size of the door directly impacts its cost:

  • Standard Sizes: Doors that fit standard dimensions are generally more affordable than doors that require custom sizing or larger dimensions.

  • Large Doors: Larger doors, such as patio or bi-fold doors, will be more expensive due to the increased materials and installation complexity.

4. Additional Features

Enhancements and additional features can add to the overall cost but offer added benefits:

  • Security Enhancements: Features like multi-point locking systems, reinforced frames, and laminated glass increase security but may come at an additional cost.

  • Energy Efficiency Ratings: Doors with higher energy efficiency ratings, such as those certified by Energy Star, may cost more initially but lead to savings on heating and cooling bills over time.

5. Glazing Options

The type of glazing used in double glazed doors affects both cost and performance:

  • Double Glazing vs. Triple Glazing: Triple glazed doors provide superior insulation but are more expensive than double glazed options.

  • Specialized Glazing: Options like tinted glass or low-emissivity (Low-E) coatings improve energy efficiency but may increase upfront costs.


Choosing the right double glazed door involves balancing your budget with factors such as materials, styles, sizes, and additional features. By understanding these influences, you can make an informed decision that enhances your home's aesthetics, security, and energy efficiency.
