Why Windows Are Such a Weak Point
Which Window Furnishings Perform Best
Not all blinds and shutters offer the same level of insulation. Plantation shutters, particularly PVC and aluminium, create a tight seal against the window frame and provide a genuine layer of insulation when the louvres are closed. HoneyCell (honeycomb) blinds are purpose-built for thermal efficiency, with a cell structure that traps air and significantly reduces heat transfer. Thicker blockout fabrics on roller blinds also help, though they generally won’t outperform shutters or honeycomb-style products for pure insulation.
Summer vs Winter Performance
Beyond the Bill: Comfort and Sustainability
Getting the Best Result
The biggest factor in energy performance isn’t just the product you choose — it’s the fit. Off-the-shelf blinds with gaps at the edges will always underperform a made-to-measure shutter or blind that seals tightly against the frame. This is one of the main reasons a professional measure and installation makes a genuine difference, not just a cosmetic one.
