301
The high performance window that turns
your home into a true haven
The 301 triple seal window is the favourite among our customers because it offers the best performance at a very competitive price.
100% exclusively German profile, triple rigid seal to increased security and watertightness, in addition to a perimeter ironwork which enables a double tilt-and-turn system with double handle and without a central mullion.
A very complete window which, in addition to offering the best quality, also looks after every detail so it blends perfectly with your home decor. The 301 comes in a wide range of colours and textures in full film, with the pristine finish of invisible welding. Additionally, thanks to the option of double film, also known as bicolour film, you can tailor the windows to the requirements of the facade of your building, without this interfering with the atmosphere of your home.

Invisible welding
The new technique to join profiles using thermal fusion, known as invisible welding, offers excellent homogeneity and airtightness. The pieces are joined perfectly with a premium exterior finish which achieves an unrivalled aesthetic.
Double tilt-and-turn
The tilt-and-turn opening applied to both sashes, without a central mullion, offers increased comfort and ventilation. The double tilt-and-turn system enables each window sash to be opened independently. Another notable aspect is the security, since it has an anti-false manoeuvre system to prevent intruders from gaining access to our homes through the window.
State-of-the-art ironwork
The perimeter ironwork ensures the window closes fully on all sides, guaranteeing the desired thermal insulation and sound proofing for our home. Ironwork with leading technology which further improves the performance of this window: optimum protection through galvanisation, chrome coating and sealing which increases the anti-corrosive protection.
Triple rigid seal

The exclusive profile for this window guarantees increased security, airtightness and watertightness. Triple value thanks to the triple rigid seal in the frame. The triple seal protects all of the closure points and provides a complete perimeter adjustment with 7 chambers for greater insulation.
