The route to Internorm quality at a more accessible price: uPVC-aluminium for a premium exterior, or full uPVC where budget matters most.
Our recommendation

Five aluminium and two timber-aluminium systems with countless models. Design yours in the Internorm Door Designer, then we make it real.
Our recommendation

Up to 15 m² of glass in a 34 mm frame. The most minimal sliding door you can specify.
Our recommendation
Internorm lift and slide door

Glazing lab
Feel the difference the glass makes
Pick a type of glazing, then drag the outside temperature. The sliders show how warm the inside pane stays, how much heat leaves each square metre, and when condensation starts to form.
- A cold inner pane is what you feel as a draught
- Moisture condenses on the coldest surface in the room
- Triple glazing keeps that surface close to room temperature
- Inner pane
- 19.3°C
- Heat loss
- 17W per m²
- Whole-window U

Outside temperature0°C
Room humidity50%
Indicative, from standard surface resistance (0.13 m²K/W) and typical whole-window U-values: single 5.0, older double 2.8, modern double 1.4, triple 0.8. Internorm quotes Uw as low as 0.62 on selected models.
Open the wall
Drag to fold the glass away
This is how a Solarlux bifold door behaves: the panels hinge together and gather into a slim stack, and the whole room opens to the view.

Good to know
Questions we are asked
Is triple glazing worth it in Ireland?
For new builds and deep retrofits, yes. Triple glazing lowers heat loss, keeps the inside pane warm, cuts condensation and noise, and is the starting point for Passivhaus. Read our full answer in Is triple glazing worth it in Ireland?
Do you supply and install, or supply only?
Both. We supply and install premium windows and doors across Ireland, and our own fitting team does the installation. We also work directly with your builder or architect where that suits the project.
Which window material should I choose?
Timber-aluminium gives natural warmth inside with a weatherproof aluminium skin outside. uPVC-aluminium is low maintenance with a premium clad exterior. Full uPVC is the most cost-effective. Our comparison guide and window finder help you decide.
Are your products Passivhaus certified?
Passivhaus-certified options are available on most of our products where a project requires it. Tell us your target standard and we will specify accordingly.
Where do you install windows and doors?
We are based in Bagenalstown, Co. Carlow, and have completed projects in Carlow, Kilkenny, Dublin, Wicklow, Wexford, Kildare, Cork and Kerry. See the areas we cover.
