The new generation of PVC profiles is created to satisfy the exigencies with quality of the new European norms. They are more functional profiles with an ample range of adaptable constructive solutions to any architectonic style, existing numerous types of marks, leaves, posts and cuarterones. 
In the following graph we describethe main PVC structures of windows. Their main advantages are: its air tightness, its sound and thermal insulation, different opening possibilities, almost no maintenance, etc... These are certainly many reasons which lead us to choose them. Reasons all of them that surely constitute tactically important points for their election.
- Outer wall thickness of 3 mm
- The frame is inclines 5º to ensure the evacuation of humidity
- Two peripheral meetings of EPDM (synthetic rubber).
- Cameras of water-drainage.
- Profiles with rounded edges.
- Optimal ironwork distribution that allows to place very resistant lockings.
The PVC systems stand out because of the multitude of possibilities that they offer, both in the color of the profile as in the type of opening.
AThus the user can decide on a color of white profile, oak color, lacquer etc...
As for the types of openings we have the following models:
PRACTICABLE LEAF
It represents the type of traditional leaf, that is characterized by a central unionand outside one. One third outer union denominated cover can be added.
TILT-AND-TURN LEAF
It is emphasized by an upper revolutionary opening that allows a moderate air entrance
PARALLEL-SLIDING LEAF
Its main virtue is the null effect that it causes on the space of the living space, when we move the leaf in parallel to the frame supported on the rails. In addition, the parallel track, with its closings in all the perimeter of the leaf, offers a greater watertightness
