Internorm Doors

Internorm doors are sold exclusively through authorised partners; they can’t be bought directly.

As an Internorm distribution partner, BJH Windows supplies, surveys, and fits the full Internorm door range across Hampshire, from initial design through to installation.

Every door is custom-made to your specification, with a choice of aluminium or timber-aluminium construction, secure to RC2, and available with triple glazing for maximum thermal efficiency.

Your Hampshire Internorm Partner

Internorm has been manufacturing windows and doors in Austria for over 88 years, and has grown into Europe’s largest producer of the systems, with more than 25 million units installed to date through a network of over 1,300 distribution partners. Every order still has to go through one of those approved partners, which is where BJH comes in.

We survey, order, and fit your Internorm door ourselves, so you get direct support from the same team throughout, rather than being passed between a manufacturer and a separate installer.

There are great benefits to choosing an Internorm door:

Five aluminium door systems and two timber-aluminium systems to choose from
Four design styles, Studio, Home Pure, Home Soft, and Ambiente, to suit period or new build homes
A five-point KFV locking system is standard
Optional fingerprint scanner or code keypad entry, for extra security
Triple glazing available for maximum thermal efficiency
A fully custom design, built to your exact specification

Specifications and Accreditation

Internorm doors are built to some of the highest technical standards in the industry, independently of any BJH-specific range:

RC2 burglar resistance, certified against forced entry
PAS24 security testing, meeting UK enhanced security requirements
Passivhaus certification on select models, for the most demanding energy efficiency standards
Triple glazing, standard on lift and slide doors, optional on entrance doors
5-point KFV locking, fitted as standard across the range

Panoramic Views with Lift and Slide Doors

If you’re opening up a garden or patio, Internorm’s lift and slide doors are worth a look on their own. The glazed panels are among the largest available, so the wall between inside and outside all but disappears when the door is open.

Every lift and slide door comes with triple glazing as standard, keeping the same thermal performance as a smaller window while giving you far more glass. For a fully uninterrupted view, Internorm’s Panorama HX 300 system offers some of the largest single panes on the market.

That keeps the hero focused purely on front doors, and gives panoramic views their own space to be a genuine feature rather than a bolted-on line. Want me to slot this into the running order, probably after customisation, and confirm where it sits before we move to the installation process?

Colours, Styles, and the Door Designer

Every Internorm door is built to order, so there’s no showroom stock to choose from, only your own specification.

Start with one of the four design styles, Studio, Home Pure, Home Soft, or Ambiente, then build from there. Choose a full door leaf or one with a glass cut-out, add side panels or a fanlight if your opening allows for it, and pick from an extensive colour range that includes weather-resistant textured finishes and timber or metallic decor effects, as well as standard solid colours. Handles range from sleek bar designs to more traditional lever styles, and glazing can be clear, obscured, or decorative depending on how much privacy you want at the door.

If you’d like to see options before committing, Internorm’s own door designer tool lets you build a version of your door on screen, which we can then talk through and finalise at your consultation.
