Description:
This aluminium-backed radiator insulation roll helps reflect heat back into living spaces and reduce heat loss through walls, making rooms feel warmer while lowering energy use. The energy saving radiator reflector foil is easy to cut and fix behind radiators, and it comes with adhesive pads for straightforward fitting in most homes.
Key Points
This 5 m x 60 cm reflector roll is a practical measure to recover heat that would otherwise escape into cavity walls. According to the manufacturer it can reflect a high proportion of radiated heat back into the room, helping to reduce heating demand. The material is a thicker laminated aluminium foil with a 3 mm approximate thickness that resists moisture and is lightweight. 🔧
Installation is simple. Cut the roll to the required length and shape, position it behind the radiator and press the supplied adhesive pads to secure the foil. The product is recyclable and designed for reuse over several seasons, which can make it a cost effective solution for older properties or those with minimal wall insulation. ♻️

Usage Recommendations
Place the reflective panel directly behind the radiator, ensuring the foil faces the room to reflect heat rather than absorb it. Leave a small air gap where possible, as this helps convective flow and improves overall performance. For uneven walls, trim the foil to fit and use additional adhesive pads to prevent sagging. In rooms with radiators mounted on external walls the effect is usually more noticeable, particularly in older properties with thinner wall insulation. 🔍
Consider that performance will vary by installation and property characteristics. The manufacturer states that the foil reflects a large percentage of radiated heat, but it will not replace full cavity or external wall insulation. Also bear in mind that the reflective surface is not a thermal barrier for conduction through wall studwork, and additional insulation may be required for complete thermal improvement.
Benefits
This reflector roll offers a low-cost way to reduce heat loss from radiators while adding little to no bulk behind the unit. It can improve perceived warmth in rooms with weak insulation and may reduce heating runtime. The product is lightweight and easy to handle, allowing quick DIY installation without specialist tools. The aluminium surface is corrosion resistant and easy to clean if dust accumulates.
