Profile class
EN 12608 grades profile wall thickness. Class A is thicker; Class B is lighter and less expensive to produce.
Profiles & Systems05 / 08
Know the profile. Know who stands behind it.
Five profile manufacturers across three tiers, supported by a practical guide to what matters inside the frame.
MADE TO MEASURE
Buyer’s guide
What separates a good window from a cheap one is not brand language. These are the things worth comparing in writing.
02
Chambers
Hollow compartments trap air and slow heat and sound. Most quality systems run five or more.
03
Seals
Two seals is standard. Three holds a closed sash measurably tighter against Pakistani dust.
04
Frame heat transfer
Published as Uf in W/m²K. Lower is better. Do not confuse it with the whole-window Uw figure.
05
Reinforcement
Large windows and doors need steel inside the profile to remain straight. It is invisible once assembled.
06
UV and colour
Stabiliser chemistry and profile grade determine how the frame behaves under years of intense sun.

Six questions worth asking.
- 01Which profile class is it, A or B?
- 02How many chambers, and how many seals?
- 03What is the frame’s Uf figure?
- 04Is the frame reinforced, and where?
- 05Is there a written colour guarantee, and how long?
- 06Who covers the installation if something fails?
Profile manufacturers
The company behind a system matters: documentation, continuity and access to the right profile all begin there.
Five companies. Three tiers.
We select the exact system after understanding the opening, exposure and budget. The companies below show the profile range available through Crosslines.

How to read the tiers
Crosslines selection guide
The tiers organise our profile range by origin, documentation, system breadth and local availability. They are not a universal performance score: the right answer still depends on the exact system and opening.
Exact series names are intentionally excluded here. Any numeric performance figure belongs to the specific system named in your written quote and will not be attributed to a manufacturer as a whole.
Not sure which tier you need?
Tell us the building, how long you plan to keep it and how exposed the elevation is. That is usually enough to point you in the right direction.
