    Description

    Envirograf SLM3 Insulation Liner for Metal Consumer Units – 100x400mm

    Fire Protection and Enhanced Safety for Consumer Units

    The Envirograf SLM3 Insulation Liner enhances the safety of metal consumer units by preventing them from becoming live due to loose connections or overheated cables. Here’s why it’s essential:

    • Fire Prevention:
      Recently, fires originating from consumer units have increased. Overheated loose cables and improper earthing create significant hazards. The insulation liner addresses these risks by expanding when exposed to heat. This expansion forms a protective barrier that prevents fire spread.
    • Intumescent Technology:
      The liner, made from intumescent material, expands upon encountering heat. This reaction creates a fire-resistant layer inside the consumer unit, offering crucial protection.
    • Simple Installation:
      Installing the liner is straightforward. Peel off the backing strip and apply it to the top, sides, and bottom of the unit, ensuring coverage around cable entries. The liner, available in various sizes, fits standard consumer units and other electrical units.

    Using the Envirograf SLM3 Insulation Liner significantly reduces fire risks and enhances the overall safety of your electrical installations.

    Cut-Off Time and Order Information
    To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

    In Stock Delivery Policy

    Free Next-Day Delivery Over £100 + VAT:
    Orders above £100 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £200 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £200 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

    Backorder Delivery Policy

    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
