Eco-Friendly System? We’ve got you covered

26 February 2020

The Stellar System is the newest installment of responsibly manufactured products from Epwin Window Systems. The company have long been an advocate of planet-friendly manufacturing.

Epwin Window Systems was the first in the PVCU sector to achieve the BES6001 accreditation for the responsible sourcing of its inputs and works to the internationally recognised ISO 14001 standard for Environmental Management.

What makes the Stellar System Eco-Friendly?

Energy Efficiency

Aluminium’s unique properties allow for significant energy savings in many applications. In addition, recycled aluminium is highly energy-efficient, using only 5% of the energy of primary production. By allowing more natural light into buildings reliance on artificial lighting is reduced saving energy.

The Stellar System insulates to excellent standards and can reach a WER of Band A+ and achieve U-values as low as 1.1W/m2K. The lower the U value, the better the insulation provided by the material.  You can find out more about this in our recent blog ‘Why UK homeowners need to choose A+ windows’.

Non Toxic

Aluminium, as the metal is non-toxic, nonmagnetic and non-sparking. It has a dull silvery appearance, because of a thin layer of oxidation that forms quickly when it is exposed to air which forms a natural protection from further oxidation. Aluminum has only one naturally occurring isotope, aluminium-27, which is not radioactive.


Our aluminium windows are made using a recyclable material. In addition, aluminium can be recycled forever. It can be melted down and reformed without losing any quality. It is estimated that 75% of the aluminium ever produced is still in use today. Recycling aluminium saves around 95% of the energy needed to make the metal from raw materials.


The Stellar system uses approximately 30% less aluminium than comparable systems. It is therefore more sustainable and less likely to generate waste and is also up to 20% quicker to fabricate. Our products have a long lifespan and need very little maintenance.

Why Us? Because Stellar is a better aluminium system for windows and doors. So, contact us today.
