BKSAI Magnetic Blackout Blinds Window for Bedroom Review

This BKSAI blind offers a 100x145cm blackout fabric that can be cut to fit any window size or shape. It relies on 12 adhesive magnets rather than traditional suction cups or screws, making it particularly useful for UPVC or wooden frames where drilling is undesirable. The material is designed not just for light exclusion, but to provide a basic barrier against external temperature fluctuations in bedrooms, nurseries, or RVs.

In a UK domestic setting, these blinds excel at eliminating the early morning sun that can overheat south-facing bedrooms. The magnetic attachment is generally more reliable than suction cups, which often fail during humidity changes, though the adhesive backing on the magnets requires a thoroughly degreased surface to remain permanent. Users will find the 'any shape' flexibility useful for awkward loft windows or skylights.

Energy savings are modest and primarily focused on reducing the need for electric cooling (fans) during summer months by reflecting solar radiation. In winter, they provide a thin additional layer to reduce draughts and convective heat loss through single or poorly insulated double glazing. We estimate only marginal annual savings—likely under £10-£15 per window—but the primary value lies in improved thermal comfort rather than significant bill reduction.

Installation is straightforward and requires no tools other than scissors. The magnets are placed around the frame, and the blind is then snapped into place; however, careful measuring is essential before cutting to ensure a tight light seal.

Zero. Aside from the initial purchase price of approximately £15.99, there are no ongoing costs. The adhesive magnets may eventually need replacing if the blind is moved frequently.
