Roof Foam Insulation Calculator Result

⚠️ For foam insulation, quantity varies by required thickness, density, and the protective layer above the foam. Volume (m³) is the primary measure; weight is a secondary estimate.

Bathroom Waterproofing Calculator

Note: Bathroom waterproofing is applied before tile installation. Choose a material suitable for wet areas and under tiles. Corners, drain areas, and joints need additional treatment before application.

Technical & Regulatory Basis

This calculator uses an estimation methodology aligned with Saudi building requirements, referencing the Saudi Building Code (SBC), relevant SASO regulations on insulation materials, the SABER platform for product conformity, and the Saudi Energy Efficiency Center (SEEC) guidelines. Material consumption rates are taken from the manufacturer's Technical Data Sheet (TDS).

Frequently Asked Questions

The Saudi Building Code defines general construction requirements. Material consumption rates are taken from the manufacturer's Technical Data Sheet (TDS).

Because quantity depends on surface condition, number of layers, material type, required thickness, waste factor, and the presence of cracks, moisture, corners, or execution details.

No, the result is an estimate that helps you form an initial picture. It is not a substitute for a technical site inspection.

Floor and wall areas are calculated based on tank shape and dimensions, then multiplied by the material consumption rate, number of layers, and waste factor.

Yes. The circular floor area and cylindrical wall area are calculated based on the tank diameter and height.

Foam volume is calculated by multiplying the roof area by the thickness in meters, then the approximate weight is estimated using the foam density from the TDS.

The calculator references the Saudi Building Code and relevant SASO regulations, using material consumption rates from the manufacturer's TDS.

No, it provides an initial estimate only. The final price and quantity require a technical site inspection and knowledge of the actual surface condition and material.

Estimating waterproofing material quantities is an important step before execution, but it is not based on area alone. The final quantity varies by surface condition, cracks, moisture level, material type, required thickness, application method, and number of layers. This calculator provides an approximate result to help you form an initial picture, while a technical site inspection remains the definitive basis for final quantity and the right insulation system.
