Fully Insulate Your Hot Tub

Hot Tubs generally arrive with little or no insulation at all – this makes them very energy inefficient. Hot Tubs can be costly to run, however, we understand that you want to maximize the usage of the hot tub you have invested in. Here at Multifoils Direct, we have created an Insulation Kit, specifically for this application to fight against heat loss.

You can choose from between two grades of material:

The EcoPro Hot Tub Insulation Kit and The Super Hot Tub Insulation Kit.

The EcoPro Hot Tub Insulation Kit contains a 6-layer Multifoil, that compresses to around 6mm. It is equivalent to around 50mm of Rigid Board Insulation, e.g. Kingspan.

The Super Hot Tub Insulation Kit contains a 19-layer Multifoil and is the highest-performing multifoil on the market. It also has true aluminium outer layers and compresses to 10mm, but equates to approximately 80mm of Rigid Board Insulation.

Both of our Hot Tub Insulation Kits include:

If you supply hot tubs and are looking for a trade discount, just get in touch and a member of our team will be able to quote you for this.

The 12m2 Kit will be suitable size-wise for a hot tub with a height no greater than 1.2m. For the 12m2 kit, you will also need to check that the circumference does not exceed 10m.

If you have a large hot tub, that exceeds 10m in circumference / 1.2m in height – it is likely you will need the 24m2 kit.

How to Install our Hot Tub Insulation Kit

  1. Work out How Much Insulation You Need

    Ask someone to hold the tape in place in one of the four corners - use this as your start point. If you Hot Tub is circular, simply measure the circumference of your Hot Tub. TIP: If you have a fabric tape measure, this would make this step easier for those of you who have a circular / not square Hot Tubs. If you have a square hot tub, you can simply measure one side and multiply by 4. If you have a rectangular Hot Tub, measure the shorter side and multiply by 2 then measure the longer side and multiply by 2. Add these 2 figures together. Note this measurement down, to prepare for cutting shortly.

  2. Check the Height of your Hot Tub

    It is worth checking that the height of your hot tub does not exceed 1.2m - if it does, Contact Us. The height of even the largest hot tubs tends to be no more than 100cm (1m). It is likely that your height will range from anything between 70cm - 100cm.

  3. Cut the Multifoil to the Correct Length

    Look at the measurement you noted down, relating to the circumference of your hot tub, in Step 1. Add 70mm to this figure. Roll the insulation out and then Cut. TIP: Pull the Insulation tort, prior to cutting with the Multifoil Insulation Scissors. This will compress the layers and make it much easier. If preferred, you can use a cutting knife and again, just ensure that the insulation is compressed beforehand.

  4. Remove the Side Panels of the Hot Tub

    You are likely to need a screwdriver for this. There will be some minor variances, depending on the Hot Tub you have but in general they are all relatively similar. They are likely to have screws on / around each of the corners on the panels. If you can remove the panels, without removing the corner panels, this is ideal. Do not remove the corner panels unless you have to, to release the main side panels.

  5. Start Installing The Multifoil

    Now you can begin installing the Multifoil Insulation. Start by tucking the multifoil behind the corner panel / strip - this will help to hold the insulation in place whilst you get started. As per the image below, tuck the material in at the top and at the bottom - by tucking this in, you are minimising the heat escaping and cold air entering. Keep insulating around the hot tub.

  6. Cut where Necessary

    Although for most of our applications, we advise to keep a continuous insulation layer - we understand for this application there are some elements, such as the control panel and pipe work, that you may need to leave accessible and therefore exposed. Simply, cut around these with the scissors provided. Be careful not to cut anything other than the Multifoil Insulation.

  7. Finish Insulating

    Once you have insulated around the whole of the hot tub (excluding the areas cut) then you should have a little excess insulation, which you can overlap slightly - in preparation for taping.

  8. Tape Around Joints and Edges

    Start by taping where you have just overlapped the insulation. You can then use that Thermaseal Foil Joining Tape to seal around any edges where air may pass. The aim is to keep this material a continuous layer where possible, so tape any area where you warm air may escape and cold air may enter.

  9. Reassemble Your Hot Tub

    Reattach your panels back on and ensure screwed securely as they were previously.

  10. Relax and Enjoy!

    Enjoy your newly Insulated Hot Tub - Stay in for longer, guilt free whilst using a lot less energy than you would have beforehand!

expand_circle_down Q&As

How does the Hot Tub Insulation Kit work?

When the kit has been installed, it will reflect heat back into the hot tub and reflect any cold away. This means less energy will be required to maintain the desired temperature.

Will the water from the hot tub damage the insulation?

No, as long as it’s correctly sealed and the insulation isn’t exposed.

Is the insulation easy to cut?

Yes, we include some Multifoil Insulation Scissors in this kit, and they will easily cut through the insulation.

How much insulation do I need for my hot tub?

Your Hot Tub has a height no greater than 1.2m which is just over 47 inches (Hot Tub heights range from between 29 and 35 inches, so this is suitable for most). Make sure the circumference is no longer than 10m otherwise you will require the 24m2 kit.
