    Who it's best for

    • Renters needing non-permanent energy fixes
    • Homeowners with large gaps under internal doors
    • Budget-conscious draught proofing

    Who should avoid it

    • You have high-pile carpets that the strip will snag on
    • You require a heavy-duty brush seal for industrial use

    Overview

    The Moonwards Draft Excluder is a 39-inch (100cm) silicone strip with a 2-inch width, designed to bridge the gap between the bottom of a door and the floor. It features a self-adhesive backing for a tool-free installation and is flexible enough to maintain a seal even on slightly uneven flooring. Available in multiple colours, it serves as a multi-functional barrier against cold air, street noise, and even light insects.

    Key features

    • 100cm length fits most standard UK doors
    • Self-adhesive backing for no-drill installation
    • Flexible silicone construction for sound dampening
    • 2-inch width covers significant door-to-floor gaps
    • Weatherproof and waterproof for external-facing use
    • Easy to trim to size with domestic scissors

    Real world performance

    In a standard UK household, these strips are most effective on doors separating living areas from chilly corridors or utility rooms. The silicone material is quiet against hard floors but may experience 'drag' or peeling issues if used on thick-pile carpets. The adhesive is strong initially, though its longevity depends heavily on how thoroughly the door surface was cleaned before application.

    Energy saving potential

    Realistic savings are modest but quantifiable; according to the Energy Saving Trust, draught-proofing a home can save around £45-£50 a year on heating bills. For a single door, this specific product might contribute a saving of £5-£10 annually by allowing you to keep the thermostat slightly lower in the draught-protected room. The primary gain is comfort rather than significant financial ROI.

    Installation

    Installation takes roughly five minutes. It requires measuring the door width, cutting the silicone to size with scissors, cleaning the door surface with alcohol or a degreaser, and applying the strip while ensuring it just touches the floor.

    Running costs

    Zero electricity or maintenance costs, though the adhesive may need replacing every 2-3 years depending on door usage and humidity.

    Pros

    • Extremely affordable entry price
    • No tools or DIY expertise required
    • Effective at blocking noise as well as air
    • Discrete design once installed

    Cons

    • Adhesive can fail on poorly prepared surfaces
    • May drag or lift on thick carpets
    • Thin silicone can tear if caught on sharp thresholds

    Alternatives

    EXTSUD Rubber Bottom Seal

    Similar price point but uses a thicker rubber material.

    Twin Foam Draft Guard

    Slides under the door instead of using adhesive; better for carpets.

    Frequently asked questions

    Can I use this on a carpeted floor?

    It works best on hard floors. On carpets, the friction may eventually peel the adhesive off the door; it is recommended to leave a 1-2mm clearance.

    Will it damage the paint on my door?

    The adhesive is strong; if removed, it may pull away loose paint or leave residue. Warm it with a hairdryer before removing to minimise damage.

    Can it be used on PVC doors?

    Yes, it adheres well to clean PVC, wood, and metal surfaces.

    Is it suitable for external doors?

    Yes, it is waterproof, but for high-traffic front doors, a screw-in brush excluder generally lasts longer.

    Final verdict

    4.0 / 5

    This is a low-cost, effective fix for draughty UK homes, particularly for internal doors leading to unheated hallways. While it won't replace proper insulation, it offers an immediate improvement in room comfort for less than £10.
