The main advantages of Double glazing:

In a nutshell, double glazing is a huge improvement compared to the windows in the olden days, especially in Ireland, where winters are damp and cold.

The main advantages of Triple glazing:

Energy Efficiency Which Wins?

Double Glazing: Rathgar has already achieved quite high efficiency at the EU building regulation levels. The majority of houses will require only the use of double glazing in the Irish moderate climate, as it is enough to reduce heating expenses and improve the level of comfort.

Triple Glazing: Provides an additional insulated advantage of up to 30-40 percent reduced heat loss. Nevertheless, the amount of time it actually pays off the extra financing may be notable, particularly in Ireland, where winter conditions are not as severe as those in Northern Europe. 

Double-glazing – It has good sound insulation. Residing in a rural area, on a residential street, or in a residential avenue? Your home will be much quieter with the installation of double glazing.

Triple Glazing – If it is surrounded by a motorway, an urban centre, a train station, or close to an airport, then triple glazing should provide impressive noise reduction. Most home receivers claim that it changes their quality of life.

Where major home upgrades are concerned, financing is important.

Frequently Asked Questions by a Home Owner

1. Assuredly not: triple glazing saves more money on energy bills in some houses than in other houses.

– Not necessarily. Although more efficient, it may not save a lot in an Irish climate to compensate for the additional cost.

2. Does triple glazing pay off?

– It depends on your insulation of the home, your budget, and where you live. In most cases, the balance lies in the case of Irish homeowners using the concept of double glazing.

3. Won’t triple glazing make my house darker?

– Contemporary triple glazing is fabricated using clear glass, providing the same amount of natural light. 

4. Is it possible to upgrade/add to double glazing to triple glazing?

– However, your frames might need to be able to support a heavier load of triple panes.

Real-Time Scenario – 

One of our clients in the city centre of Dublin replaced a single pane sash window with the new windows comprising twin pane windows. They instantly felt a warmer house, cheapening heating costs and much less street noise.

A client who resides in North Dublin selected triple glazing. The outcome was life-changing: their house is now quieter, warmer, and less cold in all seasons.

This indicates that the right decision actually depends on your whereabouts, your way of life, and what you prioritize.

Durability and Maintenance

So, what is the best option for your home?

Double Glazing: The most suitable choice for most Irish households because it possesses a great balance between cost, thermal efficiency, and comfort.

Triple Glazing: The Super-insulation, and the lowest-noise option, plus it is great in eco-homes, or where you need maximum insulation and sound-reduction.

The reality is that no one best practice fits all. It depends on your site, your budget, and what is important to you now, such as reduced heating costs or, in the future, sustainability.
