Short answer: You can see Internorm windows in person at the ThermoGlaze showrooms in Dublin. The full Internorm range is on display at our Swords showroom on the northside, and our Rathgar showroom in Dublin 6 serves homeowners on the southside. At both, you can open the windows, test the locks, compare glazing and choose colours with help from our fitting team.
New windows are one of the biggest decisions you will make on your home. They affect how warm your house feels, how much you spend on heating, how secure you are at night and how the house looks from the street. Brochures and websites are a good starting point, but most of our customers tell us the same thing after a showroom visit: they only really understood the difference once they had their hands on the product.
What Is Internorm and Who Sells It in Ireland?
Internorm is a family-owned Austrian manufacturer that has been making windows since the 1930s and is now one of the largest window brands in Europe. Its windows are made to order in Austria and are known for strong insulation, slim frames and high-quality hardware.
In Ireland, Internorm windows are sold and installed through approved partners. ThermoGlaze is an Irish-owned Internorm partner in Dublin, and our team supplies, measures and fits Internorm windows and doors in homes across the city and county.
Why You Should See Internorm Windows Before You Buy?
Every week we meet homeowners who have narrowed their choice down online but still have questions that photos cannot answer. Is the frame too bulky for a period house? Will grey look right against red brick? Is triple glazing worth it for my home?
A showroom visit answers these questions quickly. Here is what you can check:
-
- Frame size and sightlines: See how much glass you get compared to frame, which matters for light and for the look of older homes
-
- Double vs triple glazing: Stand next to both and feel the difference in weight and build
-
- Handles and locks: Turn the handles, test the multi-point locking and see how the window shuts against its seals
-
- Opening styles: Try tilt and turn, fixed and sliding options to see what suits each room
-
- Colours and finishes: Hold colour panels up against your own photos of brickwork, render or interior paint

Popular Internorm Window Systems to See in Person
Internorm makes a wide range of products. These are the Internorm windows and sliding systems our customers ask about most.
| System | Frame Type | Often Chosen For |
| KF 410 | uPVC, with aluminium outer option | Replacement windows with strong insulation and low upkeep |
| HF 410 | Timber inside, aluminium outside | Homes where people want a wood finish indoors without outdoor maintenance |
| HS 330 | Large glazed lift and slide system | Kitchen extensions and living rooms that open onto the garden |
If you like the idea of a large sliding opening, it is worth looking at our wider range of lift and slide doors during the same visit.
What Dublin Homeowners Notice First?
From years of showing these windows to customers, a few features come up again and again:
-
- Warmth: Triple glazing options help keep heat inside during long Irish winters
-
- Quiet: Well-sealed frames cut down traffic and street noise, which matters on busy Dublin roads
-
- Security: Internorm’s locking systems feel solid and give real peace of mind
-
- Build quality: The materials are made to last for decades, not just a few years
-
- Choice: Styles and colours can be matched to modern and traditional homes
Better insulation can also improve your home’s energy performance. If you are planning a wider energy upgrade, read our SEAI windows and doors grant guide first, as eligibility depends on the window specification and your home.
