Reddit reviews Duck MAX Strength Heavy Duty Insulating Film Window Kit, 3-Window, 62-Inch x 126-Inch, Indoor, 284351

I made one for my Hexamid, it was quite easy. I would suggest trying to find a window insulation kit (which is polycryo material). They usually come in large sheets far in excess of what you need for a decent bathtub and include a double sided tape. I know you are not in the US but this is what I used, for reference: https://www.amazon.com/gp/product/B015PY2BY8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

My procedure was to measure out my desired area (taking into consideration how high of a wall you want) and then I googled a way to triangle fold corners that create a waterproof fold. Use the tape to secure and I folded over the top edge to increase resistance to tearing. You can also put some tenacious tape or other strong tape on the corners so that you can punch a small hole for mitten hooks.

Measure twice, cut once. Mine turned out to be almost the same weight as the DCF bathtub available from ZPacks (just slightly over 3oz) and has had no issues or problems in use.

I got charged about $4K the replacement of every exterior window. The contractor took care of all the permits. This was probably the most restrictive part of the job and made up the vast majority of my improved insulation costs. If you are dealing with HDB, my experience was that while it was somewhat expensive, things were relatively smooth. If I had to do this again, I would have done just the bedrooms. I roughly estimate that if I were to expect these windows to repay themselves with my reduced PUB bill, I estimate my repayment time is going to be around 10-15 years.--Not great, not terrible.


I do wish that HDB would allow homeowners to take a course on safety precautions and then have them pay a fee for liability insurance and then allow us to do it ourselves. It did not look very difficult. It would save people money and make this sort of renovation much more accessible to Singaporeans. I went on Amazon and calculated that the actual cost of all the windows I installed was about S$1500 if I were in the US, so a lot of money went into the labor and permitting process.


If you don't want to do this, there are still options. My original HDB installed window frame did not have very good weather sealing. This was a significant source of noise and heat gain. Fixing this was easy with a caulking gun. I found that some heavy curtains were quite helpful, I still use them even after the new windows were installed. There are high thickness anti-convection Insulating window films are around. I tried them on one window and it was actually very effective with the thick curtains at cutting down the noise. To my ears, only slightly worse than the double-glazing. I think it would have given me almost as good energy saving if I used it on every room with aircon.--I don't have hard numbers The downside was that this solution was ugly and needed to be replaced often. Application needs a bit of practice, but if you get it wrong, the film is easy to remove. The film itself is very cheap. IIRC I used something like this.--same brand. As you can see, if you are willing to put up with the disadvantages this might actually be the best choice financially.

As before, there are a quite a few things you can do to get a decent amount of sound reduction. In any case, if you are going to pay for new windows, they will not help you much unless you have good weather sealing and well insulated doors. There are things you can do that will improve things even if you don't want to spend that sort of money. And if you do, there are things that you MUST do in order for you to enjoy the best benefit from what money you do decide to spend. Don't give in to that sinkie learned helplessness where everything also cannot do! It is 2019, we have so many options to make our lives better.

I'd go with this:

2X thickness, minor weight penalty.

Most people find the .75mil too thin and double it up. Instead of that just get the 1.5mil.

It is the same as this too! You could pick it up at like Walmart or Ace.

If you don't mind having the bedroom windows inaccessible try this and then put sound deadening curtains over:
