PVC Window Frames

Increasingly popular, PVC window frames are a cost-effective solution for increasing the energy efficiency of your home.

Make your PVC window frames project a reality

We are committed to providing excellence in PVC window frames, combining modern design, durability and energy efficiency.


PVC frames without special colors or finishes are generally cheaper than aluminum frames, making them a more affordable option for many people.

Thermal and Acoustic Insulation

PVC frames offer excellent thermal and acoustic insulation with a significant impact on reducing heating and cooling costs. PVC windows are effective at reducing external noise, making the house quieter and more peaceful.

Resistance to corrosion from salt spray

PVC has excellent resistance to corrosion caused by the sea and is a good option for construction sites less than 5km from the sea.
