Insulated Panels and Doors

Replacement, Repair & Maintenance of Air Handling Unit Insulated Panels and Doors Across the UK

AHU panels and doors are essential to the structural integrity, energy efficiency, and safe operation of any Air Handling Unit (AHU). Whether it’s a commercial office, hospital, school, or industrial facility, damaged or deteriorating panels and doors can compromise your entire HVAC system.

At Bremaco, we provide expert supply, replacement, and refurbishment services for AHU panels and access doors throughout the UK.

    What Happens When Insulated Panels and Doors Go Wrong?

    When AHU panels or doors fail, the consequences can affect both performance and safety. Common issues include:

    • Air leaks, causing pressure loss and energy inefficiency

    • Thermal bridging, leading to condensation and heat loss

    • Water ingress, resulting in internal corrosion or microbial growth

    • Reduced access or door jamming, delaying maintenance

    • Noise breakout, especially in sensitive environments

    • Non-compliance with hygiene or building regulations

    Unchecked panel damage can also compromise fire protection, structural integrity, and weatherproofing—particularly for rooftop or outdoor AHUs.

    Insulated Panels and Doors Replacement Services

    When repair is no longer viable, our team can supply and install new insulated panels or access doors to suit your AHU specification—whether it’s a standard unit or a custom-built system.

    Our service includes:

    • On-site inspection and measurements

    • Panel design to match existing specifications

    • Supply and installation of insulated doors and panels

    • Air- and weather-tight sealing

    • Optional upgrades for acoustic or thermal performance

    • Safe disposal of damaged components

    All panels and doors are manufactured using robust, weather-resistant materials and can be colour-matched where required.

      Frequent Questions

      u

      How do I know if my AHU insulated panels and doors need replacing?

      Common signs include visible rust or corrosion, loose or missing panels, air leaks, draughts, water ingress, and difficulty opening or closing doors.

      u

      Can you replace just one panel or door, or do I need a full casing replacement?

      Coil corrosion can be caused by poor water treatment, external environmental factors, lack of maintenance, or air contamination (e.g. from nearby industrial activity).

      u

      Are your panels insulated?

      Yes. All replacement panels and doors are fully insulated and weather-sealed to meet current energy efficiency and acoustic standards.

      u

      Do you offer bespoke or colour-matched panels?

      Absolutely. We can supply custom-built panels with finishes and RAL colours to match your existing unit or building requirements.
