Thermal Shutters

Internal shutters are one of the most effective window coverings for heat retention. By creating a sealed layer of air between the glass and your room, the solid louvres act as a thermal barrier, significantly reducing drafts and keeping your space much warmer during the winter months.

Research from the British Blind and Shutter Association (BBSA), found that window shutters can meaningfully reduce heat loss compared to uncovered windows and standard window dressings, saving you costs on energy bills. 

Yes, interior shutters are effective at keeping rooms cooler in summer. Closing the louvres during the hottest parts of the day blocks solar heat before it enters the room, and the layer of air between the glass and the louvres acts as a natural buffer against heat transfer. You can also angle the louvres to let light in while still deflecting direct sunlight, giving you control over both temperature and brightness without having to choose between the two.

Plantation Shutters generally outperform curtains for insulation. Because they're fitted directly to the recess, helping to eliminate the gaps around the edges where most heat escapes. The panels create a dead air pocket against the glass that slows cold transfer into the room, something curtains, even thermal-lined ones, struggle to match. Shutters also hold their insulating properties year after year without sagging or losing shape, making them a better long-term investment.
