Thermal Insulation

Thermal Insulation

Thermal insulation use increased exponentially in the construction industry since 2001, when a Dubai Municipality administrative resolution made it mandatory for all buildings – residential and commercial.

The preferred choices of insulation materials for roofs and walls are polystyrene in the form of boards and polyurethane which is spray applied, the latter having the advantages of having a lower thermal conductivity, as well as of being monolithic in form.

When insulation boards are used, leakage of heat occurs through the gaps between the boards, even when ship-lap edges are employed. The monolithic nature of spray applied insulation prevents such leakage of heat through the gaps and has the additional advantage of being a waterproof layer.

At times, the spray applied insulation is carried out on the soffit of slabs, where the heat is to be stopped from entering from open areas such as underground car parks to air-conditioned spaces above.

Soffit insulation is now more and more specified by consultants in view of the increased awareness of environmental concerns.

Owing to their large roof areas exposed to direct sunlight, the energy costs of cooling such structures are substantial. Thermal insulation on these structures by way of spray applied polyurethane cuts down cooling costs considerably, giving very significant and early returns on investment.

As the metal roofs of warehouses wear down at a faster rate than conventional concrete ones, especially around the fastening elements, water leakages are a common occurrence. Spray applied insulation protected by an ultraviolet resistant coating provides a waterproofing layer which affords a 10-year guarantee against leakage, thus gifting an additional advantage.

Al Intishar Insulations have been providing these services for over 23 years to a varied clientele, from the Ministry of Defence of the UAE to private and corporate owners of warehouses.
