About our profiles and thermal insulation

Feral Group only works with profiles of the highest quality. Our box profiles are the first choice, for exterior joinery we work with the Jansen profile system. Depending on the application or the requirements in terms of comfort, we can propose a number of types.

To guarantee perfect wind and water resistance, Feral Group works with Jansen profiles. This Swiss-made profile system is one of the best choices on the market today. Feral Group offers the choice between thermally interrupted ART15 and Economy 50 profiles and thermally interrupted Janisol & Janisol Arte profiles.

Welded tube profiles (indoor & thermally uninterrupted outdoor)

For interior joinery or spaces that are not permanently heated and where there are no requirements in terms of wind and watertightness, we can propose the standard box profile. These profiles are available in both 40 and 50 mm, which means that double-glazing is also possible here. A rewarding solution for fixed panels.

Jansen ART 15 & Economy 50 (outdoor thermal uninterrupted)

The ART15 & Economy 50 profile system is a very good compromise between insulation, comfort and slenderness if the strict insulation requirements are not to be met. These profiles have a double rubber seal that ensures wind and water tightness. In combination with double glazing (U-value 1.7), this application gives you the slimmest windows that insulate well. This is our absolute bestseller for outbuildings, poolhouses but also residential.

Janisol & Janisol Arte (Outdoor thermally interrupted)

If thermal insulation is a must or an obligation, we can propose the Janisol and Janisol Arte profile system.

Where Janisol is opening up outside, the Janisol Arte can be opened up inside. Finishes with glass battens and putty are possible in some combinations.

Stainless steel profiles

We use sturdy steel tube profiles or stainless steel profiles for shower windows and shower enclosures. The stainless steel profiles are particularly interesting in damp rooms such as bathrooms. They are corrosion-resistant and maintenance-friendly. Different colors and finishes are possible.
