    Why Clontarf Homeowners Choose Thermoglaze?

    If you live in Clontarf and your windows are showing their age, you already know the problem. Salt from the bay gets into everything. It eats at metal fittings, degrades seals, and leaves white residue on frames that no amount of cleaning will fix. Inland homes can get away with basic windows for 20 years — on the coast, that timeline shrinks to 10 or less.

    We've fitted windows and doors in homes all along Clontarf Road, Vernon Avenue, Kincora Road, and the surrounding streets. We know which products hold up in this environment and which ones don't.

    When we recommend aluminium or alu-clad frames for a seafront home, it's because we've seen the difference first-hand over years of working in this area. These systems are built to withstand the demands of coastal living while providing long-lasting performance, energy efficiency, and low maintenance.

    OUR PRODUCTS

    Windows & doors for every Clontarf property

    From the seafront houses along Clontarf Road and the avenues behind Vernon Park to the family homes around St Anne’s and Kincora — we’ve worked on all kinds of properties in this area. If your windows face the sea, we know what you’re dealing with.

    How New Windows and Doors Save You Money in Clontarf

    Coastal wind is relentless, and older windows just can’t keep it out. If you feel a draught sitting in your living room on a windy evening — even with the windows shut — your seals have failed. Our triple-glazed units sit in heavy-duty frames with compression seals that block wind, rain, and noise completely.

    For homes that face the sea directly, the noise reduction alone is worth the upgrade. Triple glazing cuts outside noise by a serious margin, which makes a massive difference if your bedroom or home office faces the promenade.

    Energy savings matter here too. Coastal homes lose heat faster because wind strips warmth from the building envelope. A-rated windows slow that heat loss right down and take real pressure off your heating system.

    Front Doors, Patio Doors and More for Clontarf Homes

    A front door on a Clontarf seafront home needs to handle everything the weather throws at it. Our composite doors are warp-proof, fade-proof, and tested against forced entry. They come in a wide range of colours and styles, from traditional panel designs to contemporary glazed options.

    For rear access, bi-fold and lift-and-slide doors are a popular choice in Clontarf — especially for homes with sea views. These doors give you a wide opening and floor-to-ceiling glass, letting you make the most of the outlook while keeping the weather firmly outside when they’re closed.

    Why Thermoglaze Clontarf

    Local knowledge.
    European quality.

    Clontarf sits right on Dublin Bay, and that means your windows and doors take a beating that inland homes never see. Salt in the air corrodes fittings, constant wind pushes against seals, and moisture gets into every gap it can find. Standard products wear down fast in these conditions.

    That’s why we recommend aluminium and alu-clad frames for seafront and near-coastal homes. These materials shrug off salt corrosion and keep performing for decades. If your current windows are showing white powder on the frames, green staining around the hinges, or misting between the panes, it’s time to replace them with something built for life on the coast.

    • Windows and doors built for coastal living

      Aluminium and alu-clad frames resist salt, moisture, and wind far better than standard uPVC. If you can see the sea from your house, these are the products you should be looking at.

    • A-rated energy and serious noise reduction

      Triple-glazed units keep heat in and cut wind noise from the bay. If your bedroom faces the sea, you'll sleep better with our windows than you ever did with the old ones.

    • Pay monthly with humm finance

      Coastal-grade windows and doors are an investment. Spread the cost with monthly payments through humm and protect your home now, not later.
