It is important that the roofs are constructed so that no dust or condensation vapours are accumulated, are easy to clean and are always in a condition that cannot contribute to product contamination. The joints between the ceiling and the walls shall be rounded.
Where possible, false ceilings should be avoided unless they are constructed of waterproof, durable, easily cleanable materials and have accessibility to the upper chamber for cleaning and disinfection.
If the ceiling is not removable, it is recommended to leave inspection hatches in strategic places in order to periodically examine above it and thus control pests.
When the building’s roofs have a clean structure without a large amount of piping, or places that lend themselves to the proliferation of pests and bacteria, it is advisable only to paint them with epoxy paint.
In all cases, light colors are recommended, helping to locate dirt and sources of infection, and thus facilitate cleaning.
Types of ceilings in commercial kitchens
There are different types of materials that can be used for these applications:
• Continuous Plaster: it is a material resistant to humidity, but with it, the paint is detached.
As it is an absorbent material, it is an important source of contamination as all types of particles in the kitchen environment stick together, smoke, grease, bacteria, etc.
Inspection records are needed for false ceilings or for pest control or facility maintenance.
• Registable plaster plates: You have the same contradictions as the previous type, but they allow access for maintenance and pest control.
• Drywall: Drywall is gypsum boards laminated between two layers of cardboard. They are very resistant to compression by the plaster and to bending by the association by the cardboard.
Among its advantages are its rapid assembly and cleaning, as it is made in dry, and provides a great final finish. It is advisable to use special plates for humidity due to a large amount of steam in these areas.
Inspection records are also needed for the maintenance of facilities.
• Plasticized fiber registrable: registerable and non-absorbent finish but difficult to clean.
• Metallic plates: non-absorbent and easy-to-clean material. It is resistant to impact, abrasive products, bacteria, and corrosion.
• Lacquered aluminum plates: large and lightweight plates. Due to their large size, the number of existing seals is reduced. Non-absorbent and washable material. Aesthetically it gives the sensation of a continuous ceiling.
• PVC panel for ceiling lining: Rigid PVC panel free of plasticizers, with a negligible smell, good resistance to acetone, practically no water absorption.
Simple to install, easy to clean, does not absorb humidity, does not corrode, does not require maintenance, very aesthetic. It will require inspection records to the false ceiling.
Commercial kitchen ceiling height
It is advisable to take the facilities to the sides of the kitchen to give the maximum possible height to the kitchen.
A minimum height of 2.7 meters (9 ft.) is recommended (especially if a hood with air supply is installed), although there are solutions in extractor hoods that can reduce this height.
What is the best roof for a commercial kitchen?
The best roof for a commercial kitchen will depend on certain factors including your budget, but in a general sense, my recommendation for a relatively inexpensive and high-performance commercial kitchen roof is a vinyl-plaster roof that does not contain any harmful substances that meet all current national and international requirements.
The roof tiles are laminated with an antistatic PVC film on the front side and a pet foil on the back side. This gives the tiles a superior, maintenance-free finish and additional thermal insulation properties.
It can be used in areas that require clean, dust-free interiors, such as computer rooms, food processing, electronics, and pharmaceutical companies.
It is very easy to clean and can also be dismantled into individual parts if one of the parts is damaged.
