In tropical country like Malaysia, it is important to have a proper heat insulation against harmful UV and its hotness. Of course, there are more reasons why roof insulation is a must for many building. It makes cost effectiveness to the building by conserving coolness in the rooms. Unofficial statistics proves more than 40% energy saving can be achieved in term of electricity bill. When building has higher insulation value against heat or building receives decreased amount of heat energy, the less likely the air-conditioner is required. On the other hand, we can also view insulation in respective of preventing cool air temperature leak out from the house.
Improving roof insulation besides save utility bill, it helps our earth by decreasing the greenhouse gas emissions through lower energy consumption. Some household who cannot afford frequent air-conditioner usage can use roof insulation as a natural way to cool down the room temperature without utilizing energy which then cause costly electricity bill, enable comfortable life at home at minimal cost is important because you spend most of the time there beside workplace.
In addition to heat insulation, some heat insulation material also offers sound insulation feature. Soundproof is also important in Malaysia’s building, especially high-rise building in city center and low-rise building near main road. These places are example where sound insulation material is required to ensure comfy life.
Heat insulation can be measured by both R-value and U-value, the first one is heat transmission or heat transfer resistance level while the latter is heat transfer rate. They have reciprocal relationship where the higher the R-value, the material performs better in resistance to heat transfer; but then, U-value should have kept at lower point because it means a weaker heat conductivity.
Thermal need is first criteria when it comes to picking up the suitable roof insulation material, it can be over cost when apply insulation material that has over specification than it is necessary. In addition, maintenance work effort, time, cost factor should also be considered. Roof insulation material shall have convenience in installation (fast and effortless), not complicated when it need to repair, replace and easy to maintain. The spare parts should also easy to be found, costless to be purchased, long lasting and less likely to be obsolete.
Rigid roof insulation in Malaysia inclusive of perlite, wood fiber, expanded polystyrene (EPS), extruded polystyrene, polyisocynaturate, gypsum board (more to ceiling underneath the roof), cellular glass, other natural and non-natural materials.
Perlite insulation material (also known as perlite insulation board) comprises of organic fiber, organic binder, expanded silicaceous volcanic glass, inorganic, perlite. Asphalt coating or other type of coating are applied to minimize the adhesiveness.
Wood fiber comprises of cane, vegetable fiber, wood in mixture with binder and filler, it also being infused by asphalt or coated by asphalt in order to boost resistance against moisture.
This material is actually a foam plastic which closed-cell insulating through sandwich format, in between glass-fiber-reinforced aluminium foil facer, organic or inorganic felt facer, glass-fiber mat facer. Chlorine-free propelling agent makes foam expandable, decreasing the interlinked space in between cell, which is then converting higher resistance level against heat. Diffusion of air along the closed-cell structure makes dramatic reduction in heat resistance, this insulating material has higher efficiency against other rigid insulation material.
Expanded polystyrene (EPS) or extruded polystyrene are two main components for this category of insulation, EPS is basically polystyrene polymer blended with additive, heat up and allocated into mould to ensure uniformity when it expands and subsequently transform into an insulation material that is similar to other material, the “closed-cell”. This material is also a good performer in sound insulation, it can achieve up to 6-stars hotel standard with minimum thickness. Extruded polystyrene is on the other hand, blended and gone through extrusion manufacturing process, expanded when in touch with atmosphere, also it is a closed-cell structure.
Crushed glass mixed with foaming additive makes cellular glass, they are placed into a mould after blended, before heating up that cause glass melting and subsequently foaming agent will be decomposed. The whole theory here summarized as expansion of mixtures, merged identical closed cell structure is the end result of insulation material.
Cellular glass insulation is composed of crushed glass combined with a foaming agent. The components are mixed, placed in a mold, and heated, which melts the glass and decomposes the foaming agent. This process causes the mixture to expand and create uniform, connected closed cells to form the insulating material.
Gypsum board is one of the most common non-structure but yet high water-resistant, fire-retardant panel that provide advanced adhesion on roof-membrane. It also acts as a vapour retardant material which can be a good cover to many under-substrate.
