PVC systems with a basic depth of 60 mm possible to achieve high thermal insulation values ​​with narrower leaf frames. They are a demonstration that they are an economical solution for the realization of building projects.

Technical data:

- Dimensions smaller standard measurement frame and leaf is 120 mm in height and view.
- Profiles of three cameras to improve thermal insulation (1.6 W/m2K) and acoustic (up to 40 dB).
- Exelente watertight thanks to its double seal system.
- Optimal values ​​in tests to check air permeability and wind resistance.
- Maximum wind resistance, 9th Class (600 Pa) DIN EN 12208
- Maximum air permeability l, Class 4 according to DIN EN 12207
- Resistance garatizada theft (Class WK2) to ENV 1627-1630
