Why Dublin Homeowners Choose French Windows Over Standard Casements

Modern French windows are designed to keep your property safe. Our uPVC French windows feature multi-point locking mechanisms and internally beaded glass, providing robust security for both residential and commercial properties. You can enjoy the stunning views and ventilation without compromising on safety.

 

 

Are French Windows as Secure as Casement Windows?

French windows are often perceived as less secure than casement windows, but modern uPVC French windows provide superior protection: 

 

✓ Multi-Point Locking: 6-point shoot bolt systems on each opening sash (12 locking points total) 

✓ Internally Beaded Glass: Prevents external removal of glazing units by burglars

✓ Anti-Snap Cylinders: Resistant to lock-snapping attacks (common in urban areas) 

✓ Laminated Glass Option: Available for ground-floor installations in high-crime areas  

How Do French Windows Increase Natural Light in Dublin Homes?

French windows provide up to 30% more glass area than standard casement windows of the same size – transforming dark, north-facing rooms common in Victorian and Georgian Dublin terraces.

Maximum Glass, Minimum Frame:

– Ultra-slim 70mm sightlines (the visible frame between glass panes)

– No central post when both sashes are open – unobstructed 180° views

– Ideal for small Dublin reception rooms that need light but have limited wall space

Perfect for Dark Irish Rooms:

French windows are particularly effective in:

– North-facing back extensions (common in Dublin terraced homes)

– Period properties with deep room layouts (Georgian/Victorian)

– Ground-floor rooms overshadowed by neighboring properties (terraced/semi-detached)

How Much Will French Windows Save on My Heating Bills in Dublin?

Our A-rated French windows reduce heat loss by up to 40% compared to single-glazed windows: 

 

Double Glazing (28mm units): 

– U-value: 1.2-1.4 W/m²K 

– Glass: Argon-filled with Low-E coating

All windows meet Irish Building Regulations Part L (2019) for thermal performance. 

 

Can French Windows Be Installed for Wheelchair Access?

Yes. We offer low-threshold French windows with just 15mm step-over height (vs. standard 150mm) – ideal for wheelchair users, mobility walkers, and buggy access.

Who Benefits:

✓ Wheelchair users and mobility aid users (walkers, rollators)

✓ Families with young children (prams/buggies to garden/patio)

✓ Elderly homeowners aging in place (reducing trip hazards)

✓ Building Regulations Part M compliance (accessibility requirements)

How Low-Threshold Works:

Our low-threshold French windows maintain full performance while reducing the bottom frame:

– Only 15mm step (vs. 150mm standard) – easily navigable

– Full weatherproofing – no water ingress or draft issues

– Same A-rated thermal efficiency

Our French windows are designed to open outwards. This design choice provides two key benefits: it maximizes internal room space and allows for an unrestricted fire escape route, making them particularly safe and functional for Dublin homes.

Yes, French windows are an ideal fire escape route. Because both sashes open fully outwards with no central post (flying mullion), they offer an unrestricted opening that provides maximum exit space in an emergency, complying with safety requirements.

We offer French windows in a variety of colours to suit period and modern homes. Available finishes include White, Light Oak, Rosewood, Cream, Black, Anthracite Grey, and Chartwell Green. These options allow you to match your windows to your property’s style.

The main difference is the opening mechanism. French windows feature two sashes that open outwards like doors, offering a full, unobstructed opening. Sliding sash windows operate vertically, sliding up and down to replicate Victorian or Georgian aesthetics. Both options offer ‘A’ rated efficiency.

To measure for a French window, take three width measurements (top, middle, bottom) and three height measurements (left, center, right) of the structural opening. Use the smallest measurement for each dimension to ensure the frame fits. Always measure the brick-to-brick opening from the outside.

Yes, Airtight provides complete supply and installation services for French windows across Dublin. Our experienced team handles the entire project, from helping you choose the best style and materials to quick and efficient installation with a 10-year guarantee.

From initial quote to completed installation, expect 4-5 weeks:

– Free consultation & quote: Within 24 hours
– Site survey & final measurements: 1-3 days
– Manufacturing: 3-4 weeks (custom-made to your exact measurements)
– Installation: 1-2 days (depending on number of windows)

Our French windows can be manufactured up to 1800mm wide × 2400mm high as a single unit.

For larger openings (common in Georgian/Victorian Dublin homes), we can install French windows as part of a multi-panel configuration with fixed sidelights.

Standard sizes for Dublin homes:
– Terraced houses: 1200-1400mm wide × 1800-2100mm high
– Semi-detached: 1400-1600mm wide × 2000-2200mm high
