Testing Flutter Shutter

Through recent years, Flutter Shutter™ has gone through various stages of testing to validate its efficiency and technology. Ensuring our energy measure adheres to all government standards is absolutely paramount. With a proven efficiency of up to 70% energy/heat loss reduction, Flutter Shutter™ is going from strength to strength. Working alongside Liverpool John Moores University to test Flutter Shutter™ at their purpose built BRE Exemplar Testing Houses, means that research and development is always in motion and the product will constantly be reviewed and scrutinised. Flutter Shutter™ has also undergone testing by BRE (Buildings Research Establishment) and awarded a SAP Rating and U-Value that will achieve an increase in the EPC rating of a property.

Validity reports are readily available upon request.

Through continuous and vigorous testing we are proud to present the typical impact of Flutter Shutter™ on the SAP Rating along with our table of U-Values.

Flutter Shutter™ vs Triple Glazing

    • No need for scaffolding to install Flutter Shutter™ as even properties within multi-level buildings can be installed with ease
    • Allows natural light to flow without compromise even with the roller down, still insulating and keeping the heat in. In addition to this, the roller material also blocks long wave infrared radiation
    • No need to remove windows, thus resulting in less landfill waste
    • Reduces noise pollution up to 80%
    • Lightweight – easy to install/remove
    • Can be installed into every window no matter the size of window sill
    • Typically costs around £351 per square metre
    • Takes on average, 1 day to install a property
    • Access issues to the windows. The installer may need to put up some scaffolding to access the windows, which can cost between £1,000 to £1,300 for an average four-bedroom property
    • Triple glazing is known for hindering natural light flow, causing a room to feel dimmer meaning lights may have to be switched on even during day-time hours
    • Landfill waste from removing single or double glazed windows to replace with triple glazing
    • Standard triple glazing can experience vibrations on the internal pane to amplify sounds
    • Heaviness can cause structural damage to the walls, allowing heat to easily escape. It will also be costly to fix if any damage occurs – this adding to your total bill
