Home/Services/Acoustic & Thermal Insulation

A quieter, cooler room,
built in, not bolted on.

Insulation layered behind your plaster ceiling or within a wall partition cuts down on heat gain and noise transfer between rooms — a detail many partition and ceiling contractors skip to save cost.

01 — Heat Reduction

A top-floor room that doesn't fight the sun.

Insulation layered behind the ceiling cuts down on heat gain from the roof space, especially in top-floor units carrying direct sun exposure through the day — often the single biggest reason an aircon runs constantly.

  • ✦Thermal insulation layersReduce heat transfer from roof spaces into the room below, especially valuable in top-floor units and homes under direct sun exposure.
  • ✦Specified to your buildingWe recommend the insulation grade and thickness that fits your budget, property type and the specific problem you’re trying to solve.
  • ✦Retrofit into existing ceilings & wallsInsulation can be added when a ceiling or partition is already being opened up for other work, not only in new installations.

02 — Sound Reduction

A partition that actually blocks sound.

Standard partition board alone blocks relatively little noise — acoustic-grade insulation inside the cavity is the real fix for a shared wall that carries too much sound between a bedroom, office or music room.

  • ✦Acoustic partition upgradesDenser insulation infill for partition walls in bedrooms, home offices and music rooms, cutting sound transfer between spaces.
  • ✦Moisture-aware installationWhere humidity is a concern, we account for vapour movement in how insulation is installed, to avoid trapping moisture in the cavity.
  • ✦Grade matched to the room’s purposeA home office needs less acoustic performance than a music room — we specify the grade to the actual use, not a single default.

Signs You Need This

When insulation is
worth the add-on.

Insulation is the most commonly skipped line item on a ceiling or partition quote — usually to the client's regret within the first hot season.

01
A top-floor room gets noticeably hotter than the rest of the houseDirect roof exposure without insulation is the most common cause of one room in a home running consistently hotter than the others.
02
Your aircon runs constantly to keep a room coolHeat gain through an uninsulated ceiling forces the aircon to work harder and longer than it should need to.
03
Noise carries between rooms or from neighboursStandard partition boards alone block relatively little sound — acoustic infill is the actual fix for a noisy shared wall.
04
You’re setting up a home office or music roomSpaces that need genuine quiet — video calls, recording, focused work — benefit from acoustic insulation far more than a standard partition provides alone.
05
You’re already opening the ceiling or wall for other workAdding insulation while a ceiling or partition cavity is already open costs a fraction of what it would to retrofit later.
Our Process

From assessment
to sealed cavity.

Insulation is typically installed alongside a ceiling or partition project, adding one to two days depending on area.

01

Site Assessment

We assess heat exposure or noise sources and recommend the insulation grade and thickness that actually addresses it.

02

Cavity Preparation

The ceiling or partition frame is prepared and any existing material cleared before insulation goes in.

03

Insulation Installation

Batts or rolls are fitted snugly into the cavity without gaps or compression, which is where insulation performance is most often lost.

04

Close-up & Sealing

The ceiling or partition is boarded and sealed, keeping the insulation layer performing as specified.

Materials & Specifications

What actually goes
into the cavity.

Material and thickness are matched to whether the priority is heat, noise, or both.

01
Mineral wool (rockwool) battsStrong acoustic and fire-resistance performance, typically specified for partition walls needing serious sound reduction.
02
Fibreglass insulation battsA cost-effective standard for ceiling thermal insulation in roof-exposed rooms, with good heat-transfer resistance.
03
50mm, 75mm and 100mm thickness optionsThicker insulation improves performance but takes up more cavity depth — we match thickness to the space actually available in your ceiling or wall.
04
Thermal performance (R-value)Higher R-value materials resist heat transfer more effectively — we specify to the R-value that suits your roof exposure, not just the cheapest option.
05
Acoustic performance (sound transmission)Denser insulation grades measurably cut sound transfer between rooms compared to an uninsulated partition cavity.
Where We Work

Insulation upgrades,
near you.

Heat and noise problems vary by property type and area — we assess each site rather than applying a blanket recommendation.

Kuala Lumpur

High-rise condo units in KL often need acoustic insulation between bedroom partitions more than thermal upgrades, given shared-wall construction.

Selangor

Landed homes across Selangor with direct roof exposure are our most common thermal insulation requests.

Puchong

Puchong terrace homes frequently combine thermal ceiling insulation with acoustic partition upgrades during a full renovation.

Shah Alam

Shah Alam’s office and industrial units often need acoustic insulation between meeting rooms and open work areas.

Kepong

Older Kepong homes with ageing roof insulation (or none at all) see the most noticeable improvement from a ceiling insulation upgrade.

Pricing Factors

What affects
the cost.

Insulation is quoted as an add-on to a ceiling or partition project — these factors move that add-on cost most.

01
Area or cavity volumeLarger ceiling or wall areas naturally require more insulation material and installation time.
02
Insulation grade & thicknessHigher-performance mineral wool and thicker batts cost more than standard fibreglass options.
03
New installation vs. retrofitAdding insulation while a cavity is already open costs significantly less than opening a finished ceiling or wall specifically for it.
04
Access & cavity depthTight roof spaces or shallow partition cavities can limit thickness options or add installation time.
05
Moisture management needsHumid or poorly ventilated areas may need additional vapour consideration, adding a small amount to the base cost.
Common Questions

Insulation
questions, answered.

Cost depends on the area being insulated, the grade and thickness chosen, and whether it’s installed alongside new work or retrofitted into an existing ceiling or wall. It’s quoted as an add-on to a ceiling or partition project after a site assessment.
