As the UK experiences another heatwave, with the Met Office forecasting above-average temperatures for August, many are seeking affordable ways to keep their homes cool. According to experts, a simple curtain trick called 'window stacking' can effectively lower indoor temperatures without the need for expensive air conditioning units or fans.
What Is Window Stacking?
Window stacking involves layering two or three different window coverings to gain greater control over heat and light. Kate O’Brien, Style Consultant at Swift Direct Blinds, recommends this method for protecting homes from summer heat. The layers typically include thermal or blackout curtains, shutters or blinds, and sheer curtains.
Thermal and blackout curtains form the outer layer. Kate explains: 'We often associate thermal with retaining heat, but the barrier they create also blocks heat and sunlight in warmer months, as well as stopping already cool air from escaping the home.' She advises choosing light-coloured fabrics, as they absorb less sunlight than dark ones.
Daytime and Nighttime Solutions
Shutters or blinds serve as a versatile daytime layer. By tilting slats, you can redirect sunlight, reduce glare, or close them completely to create a barrier against hot air. Kate notes that these are ideal for households wanting precise control over light and heat.
Sheer curtains add a stylish, airy layer that reduces sunlight without darkening the room. They allow a breeze while maintaining protection, keeping the room light and comfortable. Alternatively, double roller blinds offer two layers on a single bracket: sheer for daytime and blackout for nighttime, with added insulation benefits that keep rooms cooler in summer and warmer in winter.
This cost-effective approach can make a significant difference during a heatwave, helping Brits stay cool without relying on energy-intensive cooling systems.
