LARGLASS® is a VEC curtain wall system, made up of the latest fiberglass profile technology, obtained by pultrusion process, which was developed for fenestrations and facades when a full exterior view of glass is desired.


With the use of fiberglass profiles with low thermal conductivity (W/m K = 0.40), we have taken up the challenge of the most demanding energy efficiency certifications and developed a system that can easily meet them, such as PASSIVHAUS and MINERGIE.

Advantages of fiberglass:

Energy efficiency:

Fiberglass has a very low thermal transmission. That means it’s great for keeping the heat inside and keeping the cold outside of the buildings. This translates into lower electricity bills and more conscious global environmental protection. Fiberglass allows the reduction of the electricity bill up to approximately 50%, either for heating or cooling purposes. In addition, completely eliminates the risk of moisture and condensation on the surface of the glass or on the profiles.


Structural resistance:

Fiberglass is structurally much more capable than aluminum. This allows the use of profiles with reduced dimensions even in large glazed panes. Due to their high resistance, and no need of polyamide thermal-break, the deformation and contraction levels of fiberglass profiles are practically nonexistent.



Fiberglass is highly resistant to corrosion and rotting, revealing the perfect material to use in more aggressive environments, such as marine environments. The lifetime of fiberglass profiles is higher than PVC, wood or even aluminum. This reduces the need for periodic maintenance. The fiberglass keeps the finishing tones much more than any other material, since the base of the material is a natural U.V. protector.


Eco-Conscious production process:

The pultrusion process is low polluting, requiring small amounts of energy (up to 80% less than traditional materials, such as aluminum) and fiberglass is a recyclable material. The process of pultrusion of new profiles includes 10% of recycled material, and the remaining wastes are used as bituminous waterproofing materials. Beyond that the main component of fiberglass is glass (60-70%). Glass is silica, the second most abundant substance in the earth’s crust (26%), shortly after oxygen (50%).


Our trend-setting technology promises cost savings thanks to reduced maintenance costs and outstanding heat insulation.


Our design appeal is an additional benefit for our customers, as the window becomes a facade.


Thought the use of fiberglass reinforced profiles, we offer you the best thermal insulation in the market.

Uw = 0.6 W/m²K (Ug = 0.5 W/mK)

You save energy and costs.


LARGLASS also provides excellent sound absorption for a high quality of life (34-48dB).


LARGLASS reversible opens trought 165°. Cleaning becomes extremely easy.
