Why Drumcondra’s Homeowners Choose Thermoglaze?
If your Drumcondra home still has the windows it was built with — or even the replacements from the 1990s — you’re almost certainly losing heat and paying more than you need to for energy. The red-brick terraces in Dublin 9 are solid, well-built houses, but single-glazed timber windows were never designed to keep a house warm by today’s standards.
We’ve worked on streets right across this area: Drumcondra Road Upper and Lower, Iona Road, Grace Park Road, Home Farm Road, and plenty more. We know the window sizes, the reveal depths, and the architectural details that matter when you’re fitting new windows into a home that’s been here for over a hundred years.

View rangeHow New Windows and Doors Save You Money in Drumcondra
Heat loss through old windows is a bigger deal than most people think. In a typical Drumcondra terrace with single glazing, your windows could be responsible for 25–30% of total heat loss. That's money leaving your house every hour of every day during winter.
Our A-rated windows change that picture completely. Triple glazing with argon gas fills and warm-edge spacer bars keeps heat where it belongs—inside your home. Most of our Drumcondra customers say the first thing they notice after installation is how quiet the house is. The second thing they notice is how much warmer the rooms stay, even on cold mornings.
If your house is on a busy road like Drumcondra Road or the Swords Road, the noise reduction from triple glazing is a genuine life improvement. You'll wonder how you put up with the old windows for so long.
Front Doors, Patio Doors and More for Drumcondra Homes
A good front door finishes the look of a red-brick terrace. Our composite doors come in colours and panel designs that sit beautifully alongside period brickwork—think deep reds, dark greens, and classic blacks with heritage hardware. Every door is warp-proof, weather-sealed, and fitted with a multi-point locking system.
For the back of the house, French doors are the traditional choice on Drumcondra terraces. They swing open to give you full access to the garden without taking up the wall space that a sliding door requires. If you're extending or opening up your kitchen, talk to us about our bi-fold and patio door options too.
Why Thermoglaze Drumcondra
Local knowledge.
European quality.
Drumcondra has some of the best-known streets in Dublin — and some of the oldest windows. The red-brick terraces that line Drumcondra Road, Iona Road, and the surrounding streets were mostly built between 1900 and 1930. Many still have their original timber frames, and after a century of Dublin weather, those frames are well past their best.
The challenge is replacing old windows without making the house look like somewhere else. We've done this hundreds of times across Dublin 9. Our vertical slider and casement windows come in heritage colours and slim profiles that match the original openings almost exactly. Your house keeps its character, but your heating bills drop and the draughts disappear.
