Horizontal Slat Radiator Covers

Measure the visible width of your radiator and match it to the cover widths offered, common options here include Small 780mm, Medium c.1120mm, Large 1500–1520mm and Extra Large 1720mm, with an adjustable range around 1390–2120mm for wider radiators. If your radiator is about 1,100mm wide, a 1,120mm DuraTherm cover or the Vale 1,115mm model will give neat coverage. Also note Vale's included in our range height of 815mm on several models, so check the cover height suits your radiator and skirting clearance. If you're between sizes, the adjustable model is the safe choice for a tidy fit.

No, these covers are engineered for optimal performance; the horizontal slats are precisely spaced to allow excellent airflow so your radiator can heat the room efficiently while hidden. You might notice only a very small change in surface temperature, but overall warmth and circulation remain effective. For larger rooms, choose an appropriately sized cover (a Large 1520mm or Extra Large 1720mm) so the heat output isn't restricted by undersizing.

They're designed primarily for standard wall-mounted panel radiators, which is why most Vale models show a height of 815mm and DuraTherm offers a range of common widths. Column or very tall radiators may sit proud of a standard cover or exceed the cover height, so you'll need to check your radiator's height and profile before buying. If your radiator is unusually tall or deeply profiled, an adjustable-width cover helps with width but you may need a specialist or bespoke solution for height and shape.

The range includes White, Dark Grey and Walnut finishes across brands such as DuraTherm and Vale Designs, so you can create different looks. White brightens and suits bathrooms or small kitchens, Dark Grey gives a contemporary, minimalist feel, and Walnut adds warmth to traditional living rooms. pair a Walnut 1,500mm Vale cover with warm timber furniture to soften a lounge, or choose White 780mm covers in a compact bathroom to keep the space feeling airy.

These covers create a protective barrier that reduces direct contact with the hot radiator and the horizontal slats are designed to allow airflow while preventing easy access to the heating surface. That minimises the risk of burns and accidental knocks to radiators in family homes. Because they're described as crafted from premium, durable materials, they also stand up well to everyday bumps and curious hands.
