How much do ceiling insulation services cost in Bali?

1. Prefabworld Bali International

Address: Br. Sigaran, Jl. Kamboja No.34 Ds, Sedang, Abiansemal, Badung Regency
Contact Details: +62361460181
Business Hours:
- Monday to Sunday: 8 AM – 5 PM
Prefabworld Bali International has been refining its prefab insulation system since 2001, and it shows. Their layered wood, precision-calculated air gaps, and reflective foil make it one of the most allergy-safe and low-maintenance options for Bali’s heat and humidity.
What we like most is that the insulation is already built into their prefab ceiling panels—zero sagging, no glass wool, and way less mess.
Installations are also clean and fast, making them ideal for resorts or villas where tight timelines and aesthetics are crucial.
One thing that might throw off smaller-scale clients is their lack of flexibility. If you’re not doing a full prefab project and only need insulation materials or installation help, you’ll likely run into a few service limitations and wait for a full quotation.
Still, what impresses us is their focus on performance. From mold and termite resistance to acoustic control, the insulation works to keep your space cooler and quieter throughout the year.
We also appreciated the transparency of their spec sheets, particularly with R-value breakdowns and clear engineering logic.
Excellent company with high standards

2. Bali Building Solutions

Address: Jl. Padang Udayana No.1, Padangsambian, Kec. Denpasar Bar., Kota Denpasar
Contact Details: +628113810033
Business Hours:
- Monday to Friday: 8:30 AM – 5 PM
Bali Building Solutions impressed us with their full-package offering: they install insulation with proper ceiling framing using metal or timber, plus options like plasterboard or fiber cement finishing.
What really stood out were the options to combine ceiling installation with mineral wool, PU foam, or bubble foil. Plus, the team actually explained where each type performs best depending on your roof style and the sun exposure in Bali’s humidity.
They also conduct on-site surveys and review architectural drawings before quoting, which felt very organised and reliable. You won’t find a generic price list online, but the team provided clear cost breakdowns during our inquiry.
Another thing to note: they don’t offer pre-made insulation kits or prefab panels. Everything is assembled on-site the traditional way, which might not suit those looking for plug-and-play options.
Regardless, we were happy with how streamlined everything was. From sourcing the materials to accessing installation crews and even renting any needed tools, all in one go.
Products seem of good quality and are all listed online
“Was good to speak with a friendly native English speaker who explained the roofing options clearly. Helpful advice on which products to pick. Products seem good quality and are all listed online on their website. I would’ve been 30% cheaper to order from them unfortunately I didn’t have time to wait”

3. Mr Fixit Bali

Address: Jl. Bypass Ngurah Rai Gg. Penyu No.1, Sanur, Denpasar Selatan, Kota Denpasar
Contact Details: +628123847852
Business Hours:
- Monday to Friday: 8 AM – 5 PM
- Saturday: 8 AM – 2 PM
Mr Fixit Bali stands out for their deep-dive technical guidance tailored to Bali’s tropical climate. Instead of pushing thick bulk insulation, they explain why radiant barriers under tiled roofs, paired with proper ventilation, are a smarter move in this humid environment.
We liked how the team explained thermal bridging, condensation traps, and why double foil wrap is better for tiled roofs. Their take? Making your roof breathe is just as important as blocking heat—something most contractors don’t mention.
While trained engineers back their approach and offer a wet-season leak guarantee, it’s worth noting that they’re more of a diagnostics and repair firm than pure insulation specialists. So, you won’t find off-the-shelf packages here.
Still, we appreciate that they are integrated into one property-wide care system, from AC servicing to structural fixes. Their Care Plans, which include regular roof inspections and moisture control, make them feel like a long-term partner.
Moreover, we love that they pre-empt roof leaks, offer material-specific insulation fixes, and know how to work with Bali’s quirks.
Came perfectly in time and found out the issues within minutes
“They are busy but rightfully so. They do good job. So if you want something good you have to wait and be patient. They came perfectly in time and find out all the issues within 5 minutes. Fixed it and left. Did not even charge me. I had to ask them to invoice me they sent me a bill with very good price. Amazing people and company. Highly recommended.”

Staff members are very professional
“My wife and I had a wonderful experience with the very professional staff members of Mr. Fixit lately. They answered every questions we had and addressed all our concerns about the importance of building solid house foundations in order to minimize the potential risks afterwards. We highly recommend this company and we personally would not hesitate to work with them again in the future.”

4. GNET Indonesia

Address: Jl. Gunung Catur No.8, Padangsambian Kaja, Kec. Denpasar Bar., Kota Denpasar
Contact Details: +6281246188150
Business Hours:
- Monday to Friday: 8 AM – 4 PM
- Saturday: 8 AM – 1 PM
GNET Indonesia has one of the widest material footprints in the country. We were pleased to find they carry both glasswool and aluminium foil insulation that is ready for pickup in Bali.
What really impressed us most was their tailored product range, particularly the GNET Glasswool rolls. These come in 25 mm and 50 mm options, with densities ranging from 16 to 24 kg/m³, great for soundproofing and thermal control in Bali’s humid climate.
But a slight downside is that GNET doesn’t sell directly to homeowners, meaning you’ll have to go through a distributor or local hardware shop. It’s not a dealbreaker, but it does make price comparisons and one-off purchases a bit of a hassle.
Despite this, their insulation integrates seamlessly with their Indoboard ceiling systems and metal stud framing, which simplifies installation for builders undertaking full-room refits.
To top it off, we were glad their ceiling insulation works well with wood, PVC, gypsum, and lightweight steel frames.
Cheap prices and best quality
“The biggest distributor in Bali, those who want to look for rockwool don’t need to be confused anymore, now it’s in Bali, right on Jl. Mahendradata no 86 Padang Sambian, Denpasar.. with cheap prices & best quality.. recommendation 👍🏻👍🏻👍🏻 …”

5. CV. Putra Jaya Mandiri (TokoPJM)

Address: Jl. Imam Bonjol No.555A, Pemecutan Klod, Kec. Denpasar Bar., Kota Denpasar
Contact Details: +6285100543035
Business Hours:
- Monday to Saturday: 8 AM – 5 PM
CV. Putra Jaya Mandiri (PJM) is one of Bali’s most comprehensive ceiling and partition material hubs. Six branches island-wide offer a full spectrum of ceiling infrastructure, from hollow-core metal to gypsum boards that suit all insulation retrofits.
We found it helpful that their product lines support full ceiling assemblies, which is a big plus for anyone planning to install insulation into a suspended system.
What stood out to us was the convenience of online ordering via Tokopedia and Shopee. We value that prices, bundle options, and technical specifications are all clearly posted.
We also appreciated how their distribution network maintains reliable stock from trusted brands, especially for those working on bulk projects like villas or small resorts.
Their site isn’t overwhelming, and we liked that their staff responded promptly to our inquiries.
The only thing we found lacking was their focus on insulation itself. There are no prefab insulated panels or hybrid ceiling-insulation kits on offer. So while they’re great for ceiling prep, you’ll still need to source the insulation separately.
The price is cheap, but the quality is great
“I was really confused about where to find complete ceiling materials, then I just searched and found the PJM store, located in Denpasar, the price is cheap but the quality is great 😍👍 thx PJM store …”
