Understanding Window and Door Terminology: A Glossary for Irish Homeowners

April 4, 2025

Are you thinking about upgrading your windows and doors? Whether you’re in the bustling streets of Dublin or the serene countryside of Roscommon, understanding the lingo is crucial. At Sean Doyle Windows & Doors, we believe informed homeowners make the best decisions. Let’s demystify those technical terms and help you navigate the world of windows and doors with confidence.

Why Knowing the Terms Matters (Especially in Ireland!)

Irish weather can be unpredictable, and our homes face unique challenges. From the dampness to the wind, choosing the right windows and doors is vital for comfort and energy efficiency. Plus, understanding the terminology will help you communicate effectively with your suppliers, ensuring you get exactly what you need.

A Glossary of Key Window and Door Terms:

• U-Value:
  • This measures how well a window or door insulates. A lower U-value means better insulation, which is essential for keeping those heating bills down during the Irish winters. Think of it like the tog rating on your duvet!
• Glazing:
  • This refers to the glass in your windows. Double glazing (two panes of glass with an air gap) and triple glazing (three panes) are common in Ireland for improved insulation and noise reduction. Modern glazing also often includes low-E coatings to further improve energy efficiency.
• Lintel:
  • A horizontal beam above a window or door opening that supports the wall above. Crucial for structural integrity. Ensuring a proper lintel is installed is very important, especially in older buildings.
• Threshold:
  • The bottom part of a door frame that you step over. A good threshold prevents drafts and water ingress, especially important with our frequent rainfall. Modern thresholds also consider wheelchair access.
• uPVC (Unplasticized Polyvinyl Chloride):
  • A popular and durable material for windows and doors in Ireland. It’s low-maintenance, energy-efficient, and resistant to our damp climate. Modern uPVC is also available in many colours and woodgrain effects.
• Composite Door:
  • A door made from a combination of materials, offering excellent security, insulation, and durability. Ideal for Irish homes seeking robust protection. These doors are very strong, and require minimal upkeep.
• Multi-Point Locking System:
  • A security feature that locks the door at multiple points along the frame, providing enhanced security. Essential for peace of mind. Many insurance companies require these locking systems.
• Draught Proofing:
  • The process of sealing gaps around windows and doors to prevent cold air from entering your home. A necessity in Ireland. Modern draught proofing techniques are very effective.
• Sash Windows:
  • Traditional windows with sliding panels. Many older homes in Dublin and Roscommon have them, and modern versions offer improved energy efficiency. Modern sash windows can also tilt inwards for easier cleaning.
• Casement Windows:
  • Windows that are hinged on the side and open outwards. A popular choice for modern homes due to their versatility. They offer excellent ventilation.
