Thermal insulation membrane

Thermal insulation membrane for roofs, walls and floors: description, types and installation.

A thermal insulation membrane is a modern construction material designed to protect buildings and structures from heat loss, moisture, and the negative impact of the environment. It is a multi-layer material with high vapor permeability and the ability to prevent condensation, which is especially important when installing roofs, walls, and floors. The use of membranes increases the building's energy efficiency, reduces heating costs, and ensures a comfortable indoor climate.

High-quality thermal insulation membranes and other construction materials can be purchased in Yerevan at the RMS "GROUP" construction store, which offers a wide range of materials for construction and renovation.

Description and advantages

This is a modern construction material that serves as a waterproofing, vapor barrier, and thermal insulation. The material is based on polyethylene, polypropylene, or combined multi-layered materials. They allow moisture to escape, preventing condensation and mold formation, while maintaining the thermal barrier inside the building. Membranes are essential for roofing structures, attics, facades, and heated floors.

Advantages of Use:

• High strength and durability
• Protection of insulation from moisture and wind
• Reduction of heat loss and energy consumption
• Prevention of condensation and mold formation
• Easy installation and secure fixing
• Compatibility with most insulation types: mineral wool, polystyrene, cellulose
• Possibility of multi-layer application for enhanced protection

Modern membranes are classified according to their functional purpose and structure.

Vapor Barrier Membranes – Designed to protect insulation from internal moisture. Installed on the interior side of the structure to prevent water vapor from entering the insulation.

Diffusion (Windproof) Membranes – Provide protection of insulation from wind and precipitation while allowing water vapor to escape. Used on roofs and facades where insulation ventilation is required.

Waterproof Membranes – Protect structures from external moisture, prevent insulation from getting wet and mold formation. Often used under roofing materials and on balconies.

Universal Membranes – Combine vapor barrier and waterproofing functions, suitable for roofs, walls, and floors with various types of insulation.

Areas of application

Thermal insulation membranes are used in various construction projects: pitched and flat roofs of residential and commercial buildings; attics, loft spaces; facades with ventilated, insulated systems; heated floors and screeds; balconies, loggias, terraces; industrial and warehouse premises. Proper use can significantly extend the lifespan of a structure, improve the microclimate, and increase the energy efficiency of a building.

Installation of the membrane requires compliance with certain rules:

• Surface Preparation: The surface must be clean, dry, and level.
• Unpacking and Cutting: Carefully unroll the membrane to avoid damage.
• Installation Direction: Vapor barrier membranes are installed on the interior, waterproof membranes on the exterior.
• Fixing: Secure with a construction stapler, clips, or special fasteners.
• Seam Overlap: Sheets are laid with an overlap, and seams are sealed with construction tape.
• Protective Layer: If necessary, cover with insulation or roofing material.
