Description

The 500mm Testing Length – 5″ Twinwall Flue (125mm) is a high-quality insulated chimney component designed for testing and inspection applications within twin wall flue systems. Suitable for use with solid fuel and gas appliances, it is ideal for wood-burning stoves, gas coal effect fires, and a wide range of other solid fuel heating appliances. Its insulated twin wall construction helps maintain efficient flue gas temperatures while supporting safe and reliable operation.

Manufactured from premium materials, the outer wall is made from 0.4mm thick 304 grade stainless steel with a high-temperature black finish, while the inner wall is constructed from 0.4mm thick 316 grade stainless steel for excellent corrosion and heat resistance. Compressed rockwool insulation with a density of 200kg/m³ provides outstanding thermal performance, and all components are fully welded for strength and durability. A Locking Band is supplied to securely connect each section, and a minimum 50mm clearance must always be maintained between the outside of the flue and any combustible materials, such as timber or plasterboard, for safe installation.

Features

  • Suitable for use with solid fuel and gas appliances, including wood-burning stoves and gas coal effect fires.

Shipping & Delivery

Shipping & Delivery Information

We are committed to providing reliable, convenient, and professional delivery services to customers across Canada. Please review the information below for details about our delivery options, delivery requirements, and what to expect when your order arrives.

Free Next-Day or Scheduled Delivery

Orders over $100 CAD qualify for free standard delivery to most Canadian mainland addresses.

  • Place your order before 12:00 PM with in-stock items to qualify for next-business-day delivery where available.
  • You may also select a preferred delivery date, subject to availability.
  • Orders under $100 CAD may be subject to a standard delivery fee.
  • Standard deliveries are made Monday through Friday.
  • Weekend delivery may be available in selected areas for an additional charge. Please contact our customer service team for availability and pricing.

Delivery availability and estimated delivery times may vary depending on your location, product size, and stock availability.

Click & Collect

Need your order sooner? Our Click & Collect service allows you to collect eligible in-stock items directly from our designated warehouse or collection location.

When placing your order, simply include your preferred collection date in the order notes. Once your order is ready, we will contact you with the collection details.

If you are unsure whether your selected item is eligible for Click & Collect, please contact our customer service team before placing your order.

Delivery – What to Expect

Larger or palletised orders may be delivered using a commercial delivery vehicle equipped with a tail lift and pallet truck.

To ensure a safe and successful delivery, the delivery location must have:

  • A solid, stable, and reasonably level surface.
  • Clear and accessible entryways.
  • Sufficient space for the delivery vehicle and pallet equipment.
  • No significant steps, steep slopes, soft ground, grass, or loose gravel along the delivery route.

For palletised deliveries, the driver will move the pallet to the nearest safe and accessible point. Drivers cannot transport pallets across unsuitable terrain, carry heavy goods into a property, or move goods through areas that are unsafe or inaccessible.

If your property has narrow gates, restricted access, steep driveways, limited parking, or other delivery challenges, please notify us before delivery so we can determine whether alternative arrangements are required.

Standard delivery is generally provided as a one-person delivery service. For larger or heavier items, we recommend having someone available to assist with receiving the goods.

Unless an installation service has been specifically purchased, delivery drivers are not responsible for unpacking, assembling, installing, or positioning products inside your property.

 

Inspecting Your Delivery

For palletised or larger deliveries, please inspect your order carefully before the driver leaves.

Check the packaging and products for visible signs of damage. If damage is identified, please ensure it is clearly recorded on the delivery documentation before signing.

If the driver is unable to wait while you inspect the delivery, please note this on the delivery documentation, for example:

“Driver did not wait – delivery not inspected.”

If you discover any damage after delivery, contact our customer service team as soon as possible and provide photographs and details of the affected item and packaging.

Missed Deliveries

If you are unavailable for a scheduled delivery, additional delivery or re-delivery charges may apply.

For smaller items delivered by courier, the courier may leave a delivery notification with instructions for arranging another delivery attempt or collection.

To avoid delays or additional charges, please ensure that someone is available to receive your order during the agreed delivery window.

Additional Delivery Information

Some accessories or smaller items may be shipped separately from the main order. This can include fitting kits, accessories, replacement parts, or other smaller items.

If your order is being shipped in multiple packages, we will provide confirmation where applicable.

Standard delivery times are generally between 9:00 AM and 6:00 PM, Monday through Friday, although exact delivery windows may vary by location and carrier.

Some delivery carriers may provide SMS, email, or telephone notifications. These notifications are dependent on the carrier and are not guaranteed.

Important

Please do not schedule installers, plumbers, electricians, contractors, or other service providers until your order has been delivered and inspected.

While we make every effort to meet the estimated delivery date, circumstances such as weather, carrier delays, traffic, stock availability, or other events beyond our control may occasionally affect delivery schedules.
