Costing your Windows and Doors

Introduction: The Evolution of Windows and Doors

Gone are the days when homes had simple designs with a single main entrance door, a similar rear or side door, and standard-sized windows crafted from locally-sourced materials. As architectural designs have evolved and the demands of homeowners have changed, the choices for windows and doors have expanded tremendously. This article breaks down the costs associated with various types of windows and doors, offering insights for those planning to build or renovate in Ireland.

  • Description: Timber offerings differ widely based on the type of wood and style. While some high-end choices, such as sliding sash windows, might be costly, more common options like softwood casement windows are more affordable.
  • Maintenance: Timber requires regular upkeep, which should be considered when estimating long-term costs.
  • Average Cost: Typically around €600-700/ £650 per sqm, with some variations.

Frame Material: The Core of Cost Implications

When estimating the costs of your windows and doors, the material you choose for the frame plays a significant role. Let’s delve into the four primary options available:

1. uPVC – The Cost-Effective Choice

  • Description: Unplasticised polyvinyl chloride, commonly known as uPVC, is a widely available plastic. It often serves as a budget-friendly alternative to other materials, but premium variants are also available.
  • Average Cost: Approximately €250-300/£250 per sqm.

2. Timber – Natural Aesthetics with a Price

3. Aluclad – Best of Both Worlds

  • Description: Aluclad units combine an aluminium exterior with an internal timber finish. This design offers durability and aesthetic appeal while minimizing maintenance requirements.
  • Average Cost: Ranging from €500/£450 to €700/£650 per sqm.

4. Aluminium – Durable and Architecturally Appealing

  • Description: Aluminium’s malleability and strength make it suitable for large-scale window systems, offering clean architectural lines and expansive glass sections.
  • Average Cost: Generally exceeds €750/£700 per sqm.

Considering Design & Size

Modern architecture often demands large windows and doors, with heights stretching from floor to ceiling, which traditional manufacturers might not accommodate due to weight constraints or production limitations. Aluminium solutions are preferred for such designs due to their ability to support expansive glass panels. Moreover, when considering materials, one must account for the limitations of materials like uPVC and timber, especially for broader spans.

Door Developments & Implications

While window designs have mostly remained traditional, doors have witnessed significant advancements. From single doors to bi-folding and concertina setups, the options are many. Depending on your choice, the cost can range from a modest amount for a uPVC door to substantial figures for advanced systems. Ensure that your budget aligns with your architectural ambitions.

Triple Glazing: Is It Worth It?

Although double-glazed glass units remain popular, triple glazing is quickly gaining traction. The cost differential between the two varies, but triple glazing might inflate your budget by up to 30%. Some homeowners opt for a mix, using triple glazing on certain elevations and double glazing on others, often influenced by energy rating calculations.

Conclusion: Striking the Balance

When embarking on a construction or renovation project in Ireland, understanding the implications of your window and door choices is crucial. It’s not just about aesthetics; it’s also about ensuring that the budget aligns with the design intent. Avoid basing your budget solely on average costs per square meter, given the myriad of specifications available. Always prioritize quality, functionality, and long-term value.
