Corrugated-sheet (shinko) insulation in Al Jishshah: Foam sprayed under a corrugated metal roof between steel purlins

Corrugated-sheet (shinko) insulation in Al Jishshah

In Al Jishshah, shinko roofs bounce the noise of rare rain but let heat through, and gaps between sheets let damp air pass. Foam insulation under the shinko stops heat, noise and moisture.

What the service includes

What shinko insulation includes

  • Checking the sheets and identifying open laps and bolt holes before spraying
  • Cleaning the surface, treating rust and securing loose panels to prepare for foam
  • Spraying polyurethane foam onto the sheets so it flows into laps and holes and sets as a seamless layer
  • Applying a finish coat over the foam to protect it from sunlight and breakdown
  • Treating sun-facing shinko walls in the same way when that is part of the job
  • Answering your questions about corrugated-sheet (shinko) insulation before the work starts
How we work

From your call to an insulated roof

  1. 1

    Tell us what you have

    Call or message us on WhatsApp and describe the sheet area, whether the problem is heat, leaks or both.

  2. 2

    Preparing the surface

    The sheets are cleaned, any loose panel is secured and rust is treated before spraying, because the foam layer needs a sound surface under it.

  3. 3

    Spraying the foam

    Foam is sprayed across the sheets in steady passes, expanding to fill laps and holes and setting as a continuous layer that insulates against heat and resists rain.

  4. 4

    The protective coat

    A finish coat is applied over the foam to protect it from sunlight and wear, because bare foam breaks down over time under ultraviolet rays.

About the area

The service in Al Jishshah

In a district like Al Jishshah, roofs are usually covered with shinko sheets exposed to air, sun and Al-Ahsa's seasonal effects. Water and damp air enter through gaps between sheets and under edges, and heat passes straight to the top rooms. Insulation begins with checking the shinko and supporting structure, then cleaning before spraying a continuous foam layer that covers every gap. The foam bonds to the shinko from inside, creating thermal insulation and reducing damp air entry.

Al Jishshah is a district in Al-Ahsa governorate in the Eastern Province, close to Al Markaz, Al Jafr and As Sabat.

In Al-Ahsa, gaps between shinko sheets allow damp air and salt entry, both of which speed corrosion.

Questions

Questions about Corrugated-sheet (shinko) insulation in Al Jishshah

Spraying works from both sides depending on the situation. Spraying underneath insulates against heat, reduces noise inside the annex and stays protected from the sun by the sheets above. Spraying on top adds waterproofing and covers laps and holes. When the problem is both heat and leaks, the job often involves both sides.

The lap between two overlapping sheets is not automatically tight: heat expands the metal and cold contracts it, so laps move and small gaps open over time. Bolt holes also widen with repeated expansion. These entry points are not visible to the eye but they let water through, especially when rain comes with wind.

Yes. The foam bonds to the sheet and absorbs the vibration that turns raindrops into a drumming sound. The seamless layer stops the sheet resonating the way it does when bare. This is one of the noticeable changes for anyone who uses the annex or shelter regularly.

It suits the walls too. A shinko wall facing the sun absorbs heat and passes it straight inside, and its laps and bolt holes let in air and moisture just like the roof. Foam is sprayed onto the wall in the same way and a protective coat is added over it.

Tell us whether the problem is heat, leaks or both, whether the sheets are on the roof or the walls or both, and whether you can see rust, open laps or loose bolts. The clearer your description, the better we can work out what the surface needs before we visit.

If the top rooms overheat in summer, you hear rain noise clearly, or you see damp patches on ceilings, the shinko needs insulation.

Sprayed foam under shinko seals gaps and reduces damp air and water entry. This requires an initial check to ensure the inner surface is sound and dry.
