Question 1

What is FlashWall designed to protect?

Accepted Answer

FlashWall is a portable, folding flood barrier for entrances and building openings. It provides targeted protection at an opening where the fit, mounting arrangement and ground conditions have been assessed in advance.Start with the entrance you need to protect. AquaFence should confirm the model and complete configuration for that opening before you order. Prepare the mounting arrangement and practise deployment before a flood warning.

Question 2

What are the differences between FlashWall X2, X3 and X4?

Accepted Answer

The standard models differ in section count and overall length: X2 has two sections and is 1,250 mm long; X3 has three sections and is 1,800 mm long; X4 has four sections and is 2,350 mm long. All three are listed as 500 mm high and 660 mm wide.These are overall product dimensions, not guaranteed clear-opening sizes. The mounting arrangement determines the usable opening, so confirm the fit rather than choosing a model from the entrance width alone.

Question 3

How do I measure my entrance for FlashWall?

Accepted Answer

Record the clear opening width in millimetres between the intended mounting surfaces. Note the material and condition of each side, together with any threshold, step, slope, joint or gap in the ground.Send a front-view photograph, a close-up of each mounting surface and a photograph of the threshold. These details help AquaFence assess the fit and identify the required configuration. Do not treat a width measurement alone as confirmation of suitability.

Question 4

What water depth is listed for FlashWall?

Accepted Answer

The X2, X3 and X4 models on this page have a listed maximum water depth of 500 mm. Their listed product height is also 500 mm.The appropriate protection limit for your entrance depends on the assessed site and supplied configuration. Follow the product instructions and site emergency plan; do not assume protection above the listed depth or in flood conditions that have not been assessed.

Question 5

What ground conditions does FlashWall need?

Accepted Answer

The installation area should be flat, clean, continuous and non-permeable. The barrier must be used with the mounting arrangement and ground conditions specified for your configuration.Flag steps, slopes, gaps, uneven surfaces and changes of material before ordering. Send photographs of any uncertain areas to AquaFence so the opening can be assessed. Do not assume the barrier will compensate for an unsuitable threshold or ground surface.

Question 6

How is FlashWall mounted at the sides of an entrance?

Accepted Answer

The mounting arrangement must suit the entrance and be prepared in advance. The accessories on this page include wall brackets, suction-cup components and side connectors; the required parts depend on the selected configuration.Tell AquaFence whether the mounting surfaces are smooth glass or metal, concrete, brick, mixed materials or something else. Ask for written confirmation of the mounting method and components for your opening rather than selecting parts from their names alone.

Question 7

Does FlashWall require preparation before the first deployment?

Accepted Answer

Yes. Confirm the fit and complete set of components, prepare the mounting arrangement, and read the supplied instructions before the barrier is needed.Practise unfolding, positioning and securing FlashWall at the actual entrance. Include a check of the seals and installation area, and make sure the people responsible know where the barrier and its parts are stored. The aim is a prepared routine before a flood warning arrives.

Question 8

Can people continue using the entrance while FlashWall is deployed?

Accepted Answer

Plan access before placing a flood barrier across an entrance. Follow the site emergency-access plan and confirm how occupants, staff and responders will use alternative routes while the opening is protected.Include this in deployment training. Do not assume the protected entrance can remain in normal use or that the barrier can be removed during a flood without affecting protection. Resolve access arrangements as part of the site assessment.

Question 9

How do I deploy FlashWall?

Accepted Answer

Use the instructions supplied with your model and mounting configuration. The preparation described on this page is to unfold, position and secure the barrier, with seals inspected and the installation area clean and suitable.Practise the complete procedure in advance at your entrance. This FAQ is an overview, not a replacement for the installation instructions. Ask AquaFence to clarify any uncertain step before relying on the barrier during a flood warning.

Question 10

What should I inspect before using FlashWall?

Accepted Answer

Check the barrier and its seals, confirm that the required mounting components are available, and inspect the entrance and ground for dirt, damage or changes since the fit was assessed.Use the supplied instructions for the detailed inspection routine. If a gasket, mounting part or other component is damaged or its condition is uncertain, contact AquaFence for advice and the correct replacement before relying on it.

Question 11

Can I connect FlashWall units or adapt an existing setup?

Accepted Answer

Module connectors and side connectors are listed among the accessories on this page. Their presence in the shop does not confirm that a particular combination is suitable for your opening.Provide your existing model, article number, opening dimensions and photographs. Ask AquaFence to confirm compatibility, the complete connection arrangement and its protection limits before ordering components or modifying the setup.

Question 12

How do I clean and store FlashWall after use?

Accepted Answer

After use, rinse, dry and inspect the barrier before folding it for storage. Follow the supplied instructions for cleaning, inspection and storage of the barrier and its components.Keep the complete deployment set organised and ready for the next warning. If you find damage or deterioration during the inspection, arrange advice or replacement parts before the next use.

Question 13

Which accessories or replacement parts should I order?

Accepted Answer

The page lists mounting components, connectors, gaskets, a storage bag and other setup items. Match each part to your specific FlashWall model and mounting arrangement.For an existing barrier, provide the model or article number and photographs of the part you need to replace. For a new installation, request a complete itemised configuration so the barrier, mounting parts and quantities are confirmed together.

Question 14

What should I send AquaFence to request a fit check and quotation?

Accepted Answer

Send the clear opening width, mounting-surface materials, threshold and ground condition, and photographs of the entrance and both sides. Include your preferred model or custom-length requirement, if known, and any existing equipment details.For the Japan enquiry shown on this page, include the delivery city or prefecture. Ask the quotation to confirm the model, mounting arrangement, supplied parts, quantities, tax treatment, freight and total. The fit-enquiry guide prepares information for review; it does not certify suitability or automatically select a barrier.

Question 15

What is included in the listed FlashWall price?

Accepted Answer

The listed price identifies the named product or component. It should not be read as confirmation that every mounting part, connector, gasket or storage accessory needed for your entrance is included.Request an itemised quotation confirming the supplied assembly and quantities. The comparison on this page describes the prices as 2026 Japan EXW list prices; confirm freight, the applicable 10% consumption-tax treatment and the total payable before accepting an order.

Question 16

Can I order FlashWall in a custom length?

Accepted Answer

The listed custom overall-length ranges are 985–1,535 mm for X2 Custom, 1,535–2,085 mm for X3 Custom, and 2,085–2,635 mm for X4 Custom.These ranges describe the product length, not the clear opening it will protect. AquaFence must confirm the fit, mounting arrangement and correct model before order acceptance, including where two model ranges share a boundary. Send the entrance measurements and photographs before specifying a custom length.

Question 17

When will my FlashWall order be dispatched and delivered?

Accepted Answer

The dispatch time stated on this page is 48 hours. Your order acceptance should confirm when that period starts and whether any exception applies, particularly for a custom order.Dispatch means the order leaves; it is separate from the delivery time to your site.

What warranty and return terms apply to FlashWall?
