Eco Energy PVCu Products in Hertfordshire & London

Chase Window Company is committed to the promotion of eco-friendly products, and endorses the eco-energy range of windows. We’re all for reducing our collective carbon footprint through the use of energy efficient, high performing, and environmentally friendly windows. Heat loss through the glass in our homes is costly, and not only in monetary terms. It’s costly to the planet because the more heat lost, the more we use, which in turn means the more energy has to be produced to replace it. Of course the bi-product of creating energy for heating is carbon, which is considered a greenhouse gas, and is harmful to the beautiful planet we inhabit.

Eco-Energy Plus 6

Chase Window Company offer a range of windows called the Eco Energy Plus. A 6x chamber system, which provides better insulation, strength, and acoustic performance. The uPVC used to manufacture these windows is 100% lead free, lead being yet another harmful material. The eco-energy range of windows are constructed with the inclusion of co-extruded bubble gaskets, providing an enhanced weather seal, and with an insulating property, which means less heat can escape. This seal also stops drafts, and reduces noise penetration.

High Performance

The uPVC window frame construction process consists of creating multiple chambers, which acts as an insulator, locking heat in, making the Eco Energy Plus window system the most energy efficient window available. The windows are BFRC “A” energy rated as you would expect, but even higher A+ ratings are achievable, up to an incredible A+31. The triple glazed units have a U value of just 1.0 W/m2, which by any standards is incredibly efficient.

The Eco Energy Plus range include both our standard rebated windows in addition to our new Flush Casement. The bay window assembly is much thinner than traditional bay joints, which means more glass and a less bulky frame.

Security and Handles

Maximum security, multi-point locking systems are fitted to all Eco Energy Plus windows as standard and come complete with the ERA Five Star Guarantee. Security and Peace of Mind, and £5,000.00 worth of benefits.

Make sure your window investment is protected and covered by the UK’s most comprehensive home security guarantee.

There are 5 standard handle colours plus a range of more period handles including the traditional ‘monkey tail’ style to choose from. All of which can be viewed and selected from either of our showrooms.
