Metal roof waterproofing

Insulation of metal roofing

Industrial roofs, as they are made of metal alloys, develop very high temperatures, precisely because the metals are good heat conductors. Particularly in the summer months temperatures can reach extremely high levels, resulting in obstruction of comfortable work.

In addition, consistent and large scale contractions and expansion of materials lead to their aging faster. A characteristic sign of such wear, is that the sensitive points of the sutures or compounds show gradual relaxation and weakening of the coherent forces that keep in harmony with the construction, with consequent inflow of water.

Cool roof

Applying a cold waterproofing system turns the industrial roof into the so-called "Cool Roof" and is a catalyst. On the one hand, it protects the construction materials and, on the other hand, maintains suitable conditions for more comfortable work.

In particular, Cool Roof is defined as a coating system made of special materials with high reflectivity and a high infrared emission factor that help the roofs absorb less heat and remain as much as 35°C cooler than conventional ceilings, of the summer season. This cold coating is a single, non-joining (i.e. non-weakening) film that is fluid-free and highly elastic, keeping the surface waterproof under all temperature conditions following contraction and expansion of the material.

Advantages of Cool Roof

  1. Energy savings due to reduced use of air conditioners.
  2. Improving thermal comfort conditions for building users.
  3. Reduced maintenance and repair costs due to longer life of materials
  4. Longer life for air conditioners due to reduced cooling loads.
  5. Reducing the "Urban Thermal Island" phenomenon in cities.
  6. Reduction of air pollution and greenhouse gas emissions.

Installation method for Industrial Roof coating with Spray Polyurea

Industrial roofing with Spray Polyurea

Preliminary work

The surfaces are cleaned and removed by any dirt, dust, oil, etc. Local repairs are carried out, where necessary using a polypropylene woven sheet as reinforcement of the sealing coating. Careful preparation of the substrate is the basis for the successful application of Polyurea.

Primer

A special Primer for metal surfaces is applied to achieve perfect adhesion. The primer cover is 10 m2 / ltr. Application is carried out with a spray gun at the appropriate temperature and humidity conditions.

Waterproofing

Waterproofing is achieved with two spray coatings of polyurea, specially designed for waterproofing metal roofing.

Remarks

All application methods follow the technical instructions of the materials (humidity, application times, application temperatures etc) to avoid failures and of course be applied by certified insulators.

Environmental conditions (temperature, humidity, etc.) are one of the determinants of success or failure of the application of polyurea.

Advantages of metal roof insulation

  1. It is monolithic, ie without joints and thus without weak points.
  2. Applied very quickly
  3. It is super-elastic, does not wrinkle
  4. It resists extreme weather and heat shock
  5. It has electro-insulating properties
  6. It seals and hygromonises unimaginably
  7. It achieves absolute adhesion, in any type and shape of surface
  8. It is resistant to heavy mechanical stresses
  9. It resists chemicals and petroleum products
  10. It has excellent longevity
