3. Rubber foam for roofing: Effective heat insulation and heat resistance solution

Rubber foam is one of the widely used insulation materials in construction, especially in roofing. With excellent heat insulation and heat resistance, rubber foam helps minimize heat absorption from sunlight, creating a cool living space in the summer and warm in the winter.

Types of rubber foam used for roofing:

PE foam: Popular foam, cheap, often used to insulate corrugated iron roofs.
EVA foam: More durable than PE, better resistance to temperature and chemicals, often used for projects requiring high quality.
PU foam: Highly elastic, good load-bearing capacity, often used for industrial projects.
XPS foam: Has very good insulation ability, often used for projects requiring high insulation.

How to install rubber foam for roofing:

– Clean the roof surface: Before construction, clean the roof surface to ensure the adhesion of the foam.
– Cut the foam to size: Cut the foam into panels of suitable size for the roof area.
– Glue the foam to the roof: Use specialized glue to glue the foam to the roof, ensuring that the foam panels are glued tightly together.
– Install protective layer: After gluing foam, you can install additional protective layers such as waterproof membrane or corrugated iron to increase the durability of the roof.

Benefits of roofing rubber foam

Effective insulation: Rubber foam has the ability to prevent heat transfer very well, helping to minimize heat loss in winter and reduce heat absorption in summer.
Heat resistance: Rubber foam will reflect most of the heat radiation from the sun, helping to reduce the temperature inside the house.
Soundproof: Rubber foam also has the ability to absorb sound, helping to reduce noise from the outside environment.
High durability: Rubber foam is highly durable, resistant to weather, chemicals and other environmental factors.
Easy to construct: Rubber foam is lightweight, easy to cut, easy to bend, convenient for construction.

4. Foam rubber floor underlay

The use of foam rubber floor underlay in modern interior design is becoming more and more popular. With outstanding advantages in terms of features and aesthetics, this product not only contributes to improving the quality of life but also creates a classy living space.

In houses: Flooring of living rooms, bedrooms, children’s rooms, kitchens, etc.
In public works: Offices, hospitals, schools, etc.
In production areas: Factories, warehouses, etc.

4. Pipe insulation with foam rubber insulation

Foam rubber insulation is a layer of material wrapped around the outside of the pipe to prevent heat transfer from the outside environment into or from the inside out of the pipe. Thanks to that, the temperature inside the pipe is maintained stable, minimizing heat loss and ensuring the performance of the system.

Operating principle:

Closed cell structure: Foam rubber has a closed cell structure, containing millions of tiny air cells. These air cells act as small “insulating particles”, preventing the movement of air molecules, thereby limiting heat transfer by convection.
Low thermal conductivity: Foam rubber has a very low thermal conductivity coefficient, meaning that the ability to transfer heat through this material is very poor. This means that heat will have difficulty moving through the foam rubber layer to enter or exit the pipe.
Heat reflection: The surface of foam rubber is often treated to increase the ability to reflect heat. When heat radiation from the outside environment hits the foam rubber surface, a large part of the energy will be reflected back, minimizing the amount of heat absorbed into the material.

Factors affecting insulation efficiency:

Thickness of foam rubber layer: The thicker the insulation layer, the higher the insulation efficiency.
Cell density: The higher the cell density, the better the insulation ability.
Ambient temperature: The higher the ambient temperature, the greater the need for insulation.
Quality of adhesive layer: The adhesive layer must ensure good adhesion to avoid creating gaps, minimizing heat loss.

Application:

Hot and cold water pipe system: Keep hot water warm and prevent condensation on cold water pipes.
Refrigeration system: Protect gas pipes, cold liquid pipes.
HVAC system: Air ducts, hot and cold water pipes.
Industry: Boilers, thermal equipment, chemical plants, etc.

Advantages of using foam rubber insulation:

High insulation efficiency: Minimize heat loss, save energy.
Anti-condensation: Prevents the formation of condensation on the pipe surface, protecting the pipe from corrosion.
High durability: Withstands the impact of the environment, chemicals and temperature.
Easy to construct: Light weight, easy to cut, easy to bend.
Safe: Does not contain toxic substances, environmentally friendly.
