Polyurethane (Thermal and Waterproof Insulation)

Polyurethane and its high-quality components have exceptional thermal and waterproofing properties to mitigate the heat of summer and the cold of winter.

  • We use the finest vapor barrier paper available in the local market, meeting high standard specifications.
  • We utilize the best specialized materials for flooring, sports fields, parking lots, and more.
  • We continuously seek new and suitable materials for insulating basements and swimming pools.

Quality and Technology – Two Sides of the Same Coin

Technology is the main supporter of high-quality standards. The more advanced and modern technology we possess, the higher the quality of the product we achieve. Therefore, we are constantly striving to acquire the latest technologies to achieve the best waterproofing and thermal insulation systems.

Stages of Roof Insulation Work

First Stage (Strings)

The preliminary stage for starting roof insulation work involves dividing the roof into several sections with appropriate slopes towards the water exits (drains), descending from the highest point to the lowest point, ensuring the layer thickness at the lowest point is 5 cm.

The overall level of the roof is determined by the number and height of the drains with a slope of no less than 1%. Through this network, our technical team executes the strings to adjust the levels and determine the thickness of the foam concrete.

Second Stage: Pouring Foam Concrete

The International Technical Company has secured all necessary foam concrete equipment along with a specialized technical team with extensive experience in this field. Therefore, the company is directly responsible for meeting the required specifications and standards.

Third Stage: Spraying Polyurethane

The company has achieved significant success by adopting the new insulation system based on polyurethane. Tests have been conducted in civil engineering laboratories and global research centers.

Key Properties of Polyurethane

  • Free, uniform bonds forming a single mass.
  • High quality in achieving dual insulation with lightweight properties.
  • Liquid property allowing it to fill all cracks, holes, and imperfections.
  • Expansion property until fully set (transition from liquid to solid state).
  • Achieves very high adhesion strength on any surface it is applied to.
  • Self-initiation to achieve chemical and physical properties.

Fourth Stage: Protective Layer (Polyurethane Protection)

The International Technical Company has utilized a protective layer made from high-quality acrylic materials that meet global standards for the polyurethane system.

Given that some materials available in the local market are compliant but not up to standard specifications, and in our effort to provide the best services, achieve optimal results, and earn customer satisfaction and trust, we have imported these materials from various local and Gulf factories. This is done by dedicating specific production lines with precise special formulations.

The protective layer has been specifically manufactured for the International Technical Company to meet the following conditions:

  • High Durability: Matching the steam strength generated by pressure and temperature differences on the surface.
  • Air Release: Achieving a ratio of air release from the trapped air in holes due to pressure.
  • Breathable Protective Layer: Self-breathing protective layer.
  • Enhanced Flexibility: Ensuring compatibility as external and surface temperatures vary at different thicknesses on the same surface.
  • Resistant to Sand and Screed: Not affected by sand or screed.
  • Heat Resistance: High breaking strength against the heat generated from the outer surface.
  • UV Protection: Preventing polyurethane degradation by ultraviolet rays of the sun.
  • Moisture Resistance: Preventing polyurethane from absorbing condensed water vapor.
  • Thermal Resistance: Preserving the thermal resistance of polyurethane.
  • UV Protection: Shielding from ultraviolet rays of the sun.

Key Properties of the Protective Layer

  • Adhesion: Strong adhesion to the surface of the polyurethane material.
  • Uniformity: Complete homogeneity of the layer upon final completion.
  • Consistent Thickness: The thickness of the smooth liquid remains unchanged after drying.

Fifth Stage: Polyurethane Insulation

Polyester Fiber Roll (Polystyrene Polymers) Nonwoven Fabric Filter 100-110 g/m²

Designed to withstand hydraulic resistance against chemical elements and geological conditions, this layer ensures filtration, breathability, and protection.

  • Material Composition: The polyester fiber roll measures 3m x 100m and covers the entire surface to protect the polyurethane insulation layer from the screed layer. The screed components include gravel and other materials with sharp edges.
  • Purpose: This protective layer is applied to extend the lifespan of the polyurethane stage by safeguarding it from the abrasive screed layer.
  • Functionality: It ensures even distribution of any moisture or vapor generated by the screed across the entire surface, allowing for quick evaporation.

This strategic layering enhances the durability and effectiveness of the polyurethane insulation system.

  • Temporary Retaining Walls
  • Asphalt Overlays

Sixth Stage: Screed Leveling Strings

The preliminary stage for pouring the screed involves setting the height levels for every point across the entire surface area, regardless of its size or the number of water exit points. This is achieved by:

Reaching the Farthest Point for Water Outlets

To ensure a slope of 1 cm per linear meter to the farthest point of the water outlets, the surface is divided into practical sections using leveling strings, reaching the effective drainage perimeter. This slope ensures that any amount of water on the surface slides towards the drainage outlet for rainwater disposal.

The final slope level is adjusted by installing 6 mm thick glass strings, with the expansion joint factor set for each 2.5 meter by 2.5 meter section.

Effective insulation is a combination of:

  • Proper slope
  • Careful execution
  • High-quality insulation materials

Stages of Polyurethane Insulation

The level of final tilt is tuned-up by installation of glass tendons with thickness of 6 mm as the coefficient of expansion joints of the screed for each 2.5 meters * 2.5 meters.

After you install the spacers are casting saccharide, which is a ready-mix concrete materials to address privacy. It is then soften the saccharide by the drought in order to obtain smooth and level surface free of cracks and fissures.

In addition to the specific treatment of materials according to the technical specifications for surfaces resistant to weather fluctuations and to enhance the strength of the screed, the screed is smoothed before it dries to achieve a smooth, flat surface free of cracks and fissures.

Tarpaulin (Moisture Barrier)

It is a bitumen treated with polyester materials, available in rolls measuring 1×10 meters and 4 mm thick. Polyester acts as the actual reinforcing material for the bitumen layers, and thus, Polyester 200 is used technically.

Due to the global specifications of technical insulations, they are not available for sale in commercial stores. Instead, we have taken the initiative to implement our projects under our brand, ensuring the best quality and technical excellence in execution.

Procedures for Applying Fabric Cover:

  • The surface must be clean of any impurities or dust.
  • Apply a primer layer (the cold layer) to seal the pores of the layers over which the insulation will be applied. This acts as the bonding layer between the concrete materials and the bituminous materials, sealing the pores 100%.
  • The fabric cover is applied using a thermal welding furnace at the optimal temperature, with a 10 cm horizontal and 15 cm vertical welding layer.
