HF 520 — design meets natural aesthetics
The flush timber/aluminum window whose glass sash hides the sash frame from outside, so an opening window reads like fixed glazing. It shows the spruce, larch and oak interior options, a selection of handles and exterior colours, and how the HF 520 pairs with the KF 520.

The new KF 520 window
Internorm’s slim uPVC/aluminum window with a glass sash and I-tec Secure locking hidden in the sash. Twelve pages cover the slimline frame, plastering the frame in on up to three sides, the grey exterior colours, white or dark grey interiors and the angular handles.

I-tec Decor — digital print on the window
Digital printing applied in several layers to the interior uPVC profile, with a top coat that protects against UV and household cleaners. The spruce, oak, walnut and concrete-look designs let window interiors match floors, cabinetry or doors.

The catalogue is Internorm’s own reference book, and it follows the order in which most people make decisions. It opens with the company: a family business for 95 years, three production sites in Traun, Sarleinsbach and Lannach, and more than 30 million window and door units made in Austria. That first section also covers service, an overview of the warranty, Internorm’s 30-year repair assurance and its sustainability work, including the low-carbon insulating glass now used as standard across the range.
The PDF is laid out as two-page spreads, so the printed page numbers run well past 100 even though the file has 71 pages. Use the contents page to jump to a chapter instead of scrolling. Here is what each chapter is for:
- Innovations — I-tec Secure locking up to RC 3, I-tec Shading, I-tec Glazing, I-tec Insulation, I-tec Open for entrance doors and I-tec Decor printing.
- Renovations — why replacing windows pays back in comfort and heating costs, two family home stories, and the eight-step process Internorm partners follow when replacing windows in a lived-in house.
- Windows — the four design styles (studio, home pure, home soft and ambiente), then the uPVC and uPVC/aluminum, timber/aluminum, integrated-blind, and lift & slide and fixed-glazing systems, each with its own fact box.
- Combinations — how timber/aluminum and uPVC/aluminum windows share the same exterior cladding, so one facade can hide two interior materials.
- Entrance doors — the aluminum, timber/aluminum and timber door systems, the model series, and side and back entrance doors.
- Finishes & accessories — colours, handles, glass, the online Door Designer, Juliet balconies, security hardware, sun protection and flyscreens, a technical overview table and certifications.
How to use the brochures when you plan
A brochure is most useful when you read it with your own drawings beside it. This is the sequence we suggest to clients before a first meeting.
- 01
Start with the architecture
Pick the design style before the system. Studio is flush and minimal, home pure is square-edged, home soft is gently rounded and ambiente is contoured and traditional. The style narrows the list quickly, because not every system comes in every style.
- 02
Decide the material room by room
The combinations chapter shows the logic: uPVC/aluminum where humidity runs high, such as bathrooms, and timber/aluminum in living rooms and bedrooms, with identical aluminum outside. Note which rooms get which.
- 03
Compare the fact boxes
Each system has a fact box with its key figures, typically Uw value, sound reduction, security class, locking and construction depth. Depth deserves attention in a renovation, where the existing wall and trim limit what fits.
- 04
Mark the openings that matter most
Flag the large openings, the street-facing bedrooms and the windows you will clean from inside. These are where lift & slide doors, higher sound-reduction glazing or I-tec Secure locking earn their place.
- 05
Shortlist colours, then see samples
The catalogue itself warns that printed colours and structures can differ from the real product. Treat the colour pages as a shortlist and confirm your choice against physical samples.
- 06
Bring questions, not just pages
Send us your drawings with the pages you have marked. Our product specialists have an architectural background and will turn those notes into a window schedule and a quote.
Technical data sheets live on each product page
Brochures explain an idea; data sheets settle the detail. When you move from choosing a style to drawing a wall section, open the page for the system you are considering and scroll to the Data sheets & brochures panel near the bottom. It holds PDF data sheets with dimensions, profile sections, glazing build-ups and performance values, ready to hand to an architect, energy adviser or builder.
You will find that panel on the KF 310, KF 410, KF 510 and KF 520 pages in both uPVC and uPVC/aluminum; on the HF 410, HF 510 and HF 520 timber/aluminum pages; on KV 350, KV 440 and HV 450; on HX 300, KS 430 and HS 330; and on the entrance doors page. For Reynaers and Schüco aluminum systems, ask us and we will send the manufacturer documentation for your configuration. Some systems have one sheet per design style, so check that the sheet you download matches the profile you picked.

The trade portal is reserved for trade partners, architects and planners, and access is by registration.
Reading performance figures in older brochures
Every brochure carries its print date, and Internorm refines its figures as systems evolve. The HF 520 brochure, for example, was printed in 2024; the current HF 520 page lists Uw as low as 0.71 W/m²K and sound reduction of 35–47 dB. When a brochure and a product page differ, design with the product page and its data sheet, and we will confirm the values for your configuration in the quote.
Resources that go further than a brochure
If you design or build for a living, the brochures are only the start. Registering for the trade portal gives you Auto-CAD, DWG, PDF and Revit drawings of the complete product line, specification sheets, performance data, installation guides and drawings, certifications and test reports, and the door designer software.
For teams working toward Passive House or Net Zero, we run a 60-minute PHI-accredited Lunch & Learn at our Oakville showroom, at your office or online. And if you send drawings for a Passive House project, we will get a quote back to you within 72 hours; our Passive House windows page lists the certified systems.
Brochure and catalogue questions
No. All four PDFs download directly from this page. If you would rather go through them with someone, bring them to the Oakville showroom and we will walk through the options with the real windows in front of you.
It is Internorm’s international catalogue, so it uses European spellings such as “uPVC-aluminium” and shows European homes. The Internorm window and lift & slide systems on this site all appear in it, but the catalogue notes that not every colour, handle or option is available on every system. We confirm availability and the right configuration for a Canadian project when we prepare your quote.
Because I-tec Secure is built into the KF 520 as standard, and the system can reach resistance class RC 3. Instead of locking pins, flaps in the sash press into the frame on all four sides when you turn the handle, which makes levering the window out virtually impossible. The class you get depends on the configuration you order.
Printed and on-screen colours are never exact, so compare against physical samples before you decide. Book a visit to our showroom at 217 Speers Rd. Unit 8 in Oakville to see Internorm windows, doors and finishes in person.
Installation guides and drawings sit in the trade portal along with the CAD and Revit files. Homeowners rarely need them; your builder or installer does, and we coordinate those details with them directly. Where a third party installs, our Supply & Supervision service adds on-site supervision for the first few days.
The data sheet for each system you have chosen, plus the glazing specification in your quote. Brochure figures are “as low as” values, a best case for a particular size and glazing, not the value for your project.
Read the catalogue, then talk it through
Bring your marked-up pages and drawings to the Oakville showroom, or send them ahead. We will turn your shortlist into a specification and a quote.
