Energy Efficiency

All Window Warehouse casement windows can achieve the highest A+ energy rating and reach an A window energy rating with a standard warm edge, argon filled Low-E glass unit, making them highly cost effective. This is certified by the BFRC (the British Fenestration Rating Council) who are the UK’s national system for rating the energy efficiency of windows.

Our energy efficient windows are registered by BFRC (the British Fenestration Rating Council).

PVCu Window Security and Hardware

Our PVCu windows are supplied with greenteQ handles with a 10-year guarantee. There’s a choice of Inline or Cranked in a variety of durable colours including Chrome, Satin, Gold, Black, White and Bronze. We have more information available on our range of hardware products and options so contact us today on 023 9232 7744.

High Security as Standard

High security is built into our PVCu windows as standard. Every window is fitted with reverse action anti-jemmy twin cam, shootbolt locking and Guardian high tensile steel hinge protectors. They are tested to exceed up to twice the requirement of the PAS security standard.

Security can be enhanced further with the option of Trojan Stallion Shootbolt locking mechanism with BBA Enhanced Resistance to Intrusion security accreditation.

How Guardian Hinge Protection Works

Guardian Hinge Protection high tensile steel claw and hook plates are fixed directly to the window sash and frame reveal close to the hinges. If the window is forced or jemmied the two sides hook together. The more force applied the more the protector locks together to prevent the window from being jemmied off its hinges.
