Dublin weather is not kind to windows. Rain, wind and salt air from the coast all take their toll, and many homes have upstairs windows that are awkward to clean from outside. Inward opening alu-clad windows from ThermoGlaze solve most of these problems. They open into the room, so you reach every pane from inside, and the aluminium shell outside handles the weather.
This guide explains how they work, where they suit best, and what to check before you buy.
What Are Inward Opening Alu-Clad Windows?
Inward opening windows swing into the room instead of out into the street or garden. An alu-clad window pairs a timber or insulated core inside with a tough aluminium layer outside. You get a warm interior finish and a low-maintenance exterior.
Many inward opening designs are tilt and turn windows. The handle gives you two options:
- Tilt: the top of the sash leans in for steady airflow
- Turn: the whole sash swings open inward for full ventilation and easy cleaning
Reasons Dublin Homeowners Choose Inward Opening Windows
1. You Clean Both Sides From Inside
This is the first thing most people notice. Open the sash fully and wipe the outer glass from a safe position in the room. There are no ladders and no reaching out of upstairs windows. It matters most in apartments, townhouses and any home with first-floor or second-floor windows.
2. Better Security
Inward opening sashes sit tight against the frame when closed. Multi-point locking hardware holds the sash at several places around its edge. Because the hinges and locking points face the inside, there is less for anyone to get at from outside.
3. Controlled Ventilation
Tilt mode lets fresh air in without leaving a wide gap. Rain is less likely to blow in, and you can leave a window tilted while you are out. Good airflow also helps reduce condensation, which is a common complaint in Irish homes.
4. Strong Energy Performance
Tight seals and quality glazing keep heat in during winter. Warmer rooms and fewer draughts help comfort, and they can help your Building Energy Rating when combined with other upgrades.
5. A Clean, Modern Look
Alu-clad frames have slim sightlines and sharp lines. They suit new builds, extensions and renovated period homes. You can choose from a wide colour range for the outside and a different finish inside. The alu-clad window range shows the styles available.
6. Low Maintenance
The aluminium exterior resists fading, rot and flaking paint. You will not be sanding and repainting every few years.
Inward Opening vs Outward Opening Windows
| Feature | Inward Opening Alu-Clad | Traditional Outward Opening |
| Cleaning outer glass | From inside the room | Often needs outside access |
| Security | Hardware sits on the inside | Hinges and stays face outward |
| Ventilation options | Tilt and full turn | Usually one open position |
| Wind exposure | Sash stays inside the frame line | Open sash can catch the wind |
| Upstairs suitability | Very good | Harder to clean and manage |
| Exterior upkeep | Very low | Depends on material |
Where Inward Opening Windows Work Best?
- Upstairs bedrooms and landings: safe cleaning and easy airflow
- Apartments and townhouses: no outside access needed
- Coastal homes in areas like Clontarf and Howth: the aluminium shell handles salt and wind
- Kitchens and bathrooms: tilt mode helps clear steam and cooking smells
- New builds and extensions: clean lines match modern architecture
One practical point: the sash swings into the room, so plan around curtains, blinds, radiators and furniture. ThermoGlaze can walk you through layout options on site or in the showroom. If you want to compare formats first, the window configuration page is a good place to start.
What to Check Before You Buy?
Ask these questions of any supplier:
- What U-value does the glazing reach?
- Is the hardware multi-point locking?
- What guarantee covers the frame, glass and finish?
- Who surveys and fits the windows?
- Are you being shown a real sample, not just a brochure?
If you want to see premium European engineering, look at Internorm windows alongside the alu-clad range.
Grants and Finance
Some window upgrades may qualify for support under Irish energy schemes. Eligibility depends on the glazing specification and your home, so check the current rules on the SEAI windows and doors grant page before you order. If you would rather spread the payment, finance by humm is available.

FAQs
1. What are inward opening alu-clad windows?
They are windows with an aluminium outer layer that open into the room. Most use tilt and turn hardware.
2. Are inward opening windows good for Irish weather?
Yes. The sash seals tightly against the frame, and the aluminium exterior handles rain, wind and coastal air well.
3. Can I clean inward opening windows from inside?
Yes. When the sash opens fully, you can reach the outside glass without leaving the room.
4. Are inward opening windows secure?
They use multi-point locking, and the hinges face inward. This makes them a strong choice for security.
5. What is the difference between tilt and turn and inward opening?
Tilt and turn is one type of inward opening window. It adds a tilt position for ventilation on top of the full inward swing.
6. Do alu-clad windows need much maintenance?
No. The aluminium finish resists fading and needs only an occasional wash.
7. Will inward opening windows help reduce condensation?
Tilt mode increases airflow, which helps clear moisture, especially in kitchens, bathrooms and bedrooms.
8. Do inward opening windows work with curtains and blinds?
Yes, but you need to allow space for the sash to swing. Your installer can advise on blind types and fixing positions.
9. Are these windows suitable for period homes in Dublin?
Often yes. The slim frames and colour choices fit many period and modern properties. Conservation areas may have extra planning rules, so check before you order.
