Allowing abundant natural daylight into the home while preventing heat loss, our passive flat roof windows set a new benchmark for energy-friendly building components.

BENEFITS OF PASSIVE FLAT ROOF WINDOWS

In order to achieve Passivhaus status, a property must meet numerous energy performance criteria – but you need not be aiming for passive certification in order to enjoy the benefits of passive windows. If you want to lower your carbon emissions, reduce your energy bills, or create an ambient internal temperature all year round, then passive flat roof windows could be ideal for you.

Passive windowsare thermally broken and feature at least three layers of glass, separated by highly efficient protective gas. These airtight layers provide a fantastic level of defence against heat loss, which will enable you to instantly reduce your energy output – not to mention your utility bills! As well as boasting extraordinary thermal performance, passive flat roof windows also provide fantastic airtightness, ridding your home of draughts.
