European Windows in Oakville: Visit the InterHaus Internorm Showroom
Our showroom on Speers Road is where homeowners, architects and builders come to open a tilt and turn sash, compare frame materials side by side and try a lift-slide door before they decide. InterHaus supplies and installs Internorm windows and doors in Oakville, across Halton and throughout Canada.
The short answer
InterHaus, the official Internorm dealer in Canada, has its showroom at 217 Speers Rd. Unit 8, Oakville. There you can operate Internorm tilt and turn windows, compare uPVC, uPVC/aluminum and wood/aluminum frames, and try lift-slide and entrance doors. Call +1 (437) 826-2067 to book time with a product specialist. InterHaus supplies and installs windows and doors in Oakville and across Halton.
Windows you can handle, not just look at
A window is hardware you will operate thousands of times, and a showroom is the only place to find out how it feels before you buy. Our displays sit under a hexagonal LED ceiling in the Speers Road unit, and they are there to be used: lock the sashes, tilt them, swing them open and look closely at how the corners and seals are finished.
What sits on the floor changes from time to time. If you want to see a particular model, finish or door design, mention it when you book. If it is not on display, a product specialist will take you through its data sheet, the Internorm catalogue and photos of it installed.
Six things worth trying at the Oakville showroom
Work the tilt and turn handle
One handle does everything: closed, swung inward like a door, or tilted at the top for ventilation. Feel how firmly the sash pulls in as it locks. More on our tilt and turn windows page.
Compare three frame materials
Put white uPVC, uPVC with an aluminum shell, and timber with aluminum outside side by side. Our frame material guide covers the trade-offs.
Ask about I-tec Secure
Internorm’s concealed locking uses flaps that press into all four sides of the frame, making a window very hard to lever open.
Move a lift-slide door
Turn the handle and push. Internorm lift-slide doors run on rollers, so a large glass panel moves with surprisingly little effort.
Stand at an entrance door
All-aluminum and timber/aluminum entrance doors, with U-values as low as 0.75 W/m²K and more than 30 design options in the AT models.
Settle glass and colour
Triple, safety and design glass change how a window looks, and powder-coated aluminum cladding can differ in colour from the interior.
How to book a showroom visit
You can visit at any stage, from a first idea to finished drawings. A little preparation makes the hour far more useful.
- 01
Book a time
Call +1 (437) 826-2067 or toll-free (888) 770-4917, or email info@interhaus.ca, and tell us roughly what you are working on so a product specialist can set time aside.
- 02
Bring what you have
Photos of your current windows, approximate sizes, drawings or a window schedule, and notes from your architect or builder.
- 03
Bring the people who decide
If a designer, builder or partner has a say, bring them. It is far easier to agree on frame, colour and style while standing at the same window.

You leave with a recommendation and a list of what we need for an accurate quote. Passive House projects can get a quote within 72 hours.
Lakefront houses, heritage streets and new custom builds
Homes near Lake Ontario take wind and driving rain off the water, so how a window seals matters as much as how it insulates. Internorm tilt and turn sashes close against the frame on all sides with multiple gaskets. In Ontario, windows must conform to the North American Fenestration Standard and its Canadian Supplement, with performance grades chosen for the location, so ask your designer early which grade an exposed lot calls for.
On the older streets, character comes first. If your home is designated or in a Heritage Conservation District, check with the Town’s heritage planning staff before changing street-facing windows, and before ordering.
Custom homes on larger lots bring long glass walls, lift-slide doors to the pool or garden and energy targets set by the architect. The showroom lets you judge large-format options at full size. For the energy code, Oakville is in climate Zone 1, at 3,760 heating degree-days and a January design temperature of −18 °C according to SB-1.
The Oakville and Halton project path
Because the showroom is local, an Oakville project can move easily between the display floor and your kitchen table, and you can come back with your designer or builder once drawings are further along.
Once the openings are defined, we prepare a specification and a detailed quote. After you approve sizes and finishes, Internorm makes every unit to measure at its plants in Traun, Sarleinsbach and Lannach, Austria, and it reaches your site through our local warehousing in Ontario.
- Supply only, delivered to your Oakville or Halton site
- Supply and install by our qualified fitters
- Supply with a few days of on-site supervision for your own installer
- After-sale adjustments, greasing hinges and hardware fine-tuning
Incentives for Oakville homeowners
The Town of Oakville’s home energy page lists no Town loan or rebate for windows. It points residents to the provincial Home Renovation Savings Program, which pays $100 per rough opening for windows and doors replaced with ENERGY STAR certified models.
The conditions are firm: an energy assessment before any work, at least three window openings or one door, and a second qualifying upgrade such as insulation, because windows alone do not qualify. New builds are excluded, and the published terms end on December 31, 2026. Our European windows cost guide explains what drives the price of the windows themselves.

Projects to look at before you visit
Our projects page shows real InterHaus work: the Passive House Residence in Niagara-on-the-Lake, the Etobicoke Passive House Residence, a high energy efficient home in Mulmur, a private residence near Kingston, a renovation in Ottawa, the Devil Lake Cabin and the Alcove PH Cottage in Québec.
The photo shows an arched, multi-pane window going into the Niagara-on-the-Lake Passive House, proof that made-to-measure European windows are not only for flat-roofed modern homes. If your project is in the city, see European windows in Toronto.
“This was a VIP experience from start to finish. Fast, friendly and effective service. It really helped that Vik is an architect, she was able to guide us through the entire process and coordinated directly with our designer. The windows are top-notch, but the service was better than the product.”
