A north-east winter is a serious test for any home. Windows are the weakest link, and shutters are one of the few interior changes that meaningfully push back against that.
How the insulation works
Closed shutters create a still air pocket between the glass and the room. Still air is a remarkably good insulator. Combined with the timber or faux-wood panel itself, you're adding a measurable thermal layer where the room loses the most heat.
What the research says
Independent testing in the UK has shown that solid wood shutters can reduce heat loss through a window by up to 50% compared with bare glass. Real-world savings depend on your home, but most clients notice the difference in the first week.
Summer matters too
Closed louvres on a south-facing room in July keep the room noticeably cooler. As more Newcastle homes install heat pumps, that matters — efficiency falls fast when interiors overheat.
