Our French windows are designed to open outwards. This design choice provides two key benefits: it maximises 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.

Yes, our French windows are highly energy efficient. They are available with 'A' rated double or triple glazing, which can reduce heat loss by up to 40%. The units are Argon Gas filled with a Low E coating to keep your home warm in winter and cool in summer.

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.

Yes, because both sashes open fully outwards, you can easily reach the exterior glass surfaces from inside the room without ladders or special tools.

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: Owen responds within 24 hours, books the earliest available survey slot, completes final measurements, manufacturing 3-4 weeks (custom-made to your exact measurements), installation 1-2 days (depending on number of windows). Lead times may be longer during peak season (April-September). Most Dublin installations are completed within 5 weeks.

Our French windows can be manufactured up to 1800mm wide x 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: Terraced houses 1200-1400mm wide x 1800-2100mm high, Semi-detached 1400-1600mm wide x 2000-2200mm high.

Yes. We offer French windows with integrated blinds fitted between the glass panes. Benefits: No dusting or cleaning required, perfect for high-traffic areas (patio doors), child-safe (no hanging cords), clean modern aesthetic. The blinds are sealed within the double or triple glazing unit and controlled via magnetic sliders. Pricing premium is approximately €200-300 per window depending on size.

Yes. While our standard triple glazing uses Argon gas (U-value 0.9 W/m²K), we offer an upgrade to Krypton gas for maximum insulation. Krypton-filled triple glazing achieves U-value 0.8 W/m²K (better than Argon), enhanced soundproofing, ideal for north-facing rooms, coastal properties (Howth, Malahide, Portmarnock). The Krypton upgrade adds approximately €150-200 per window.
