What is the difference between interior plywood and exterior.
Plywood is widely used in the production of construction and repair work. In addition, the sheets are used in the manufacture of furniture and packaging, in mechanical engineering. Plywood sheets are made from thin sheets of veneer laid perpendicular to each other when glued together. The number of such thin sheets can range from 3 to 23. After they are glued together, a strong building material is obtained. Deciduous and coniferous trees are used for plywood production.
Sheets of interior and exterior brands are in the greatest demand in the construction materials market. Before making a final choice, the buyer needs to evaluate the quality of the sheets, understand the conditions under which a particular brand should be used. Often these types of plywood are made of the same wood material, they differ only in the adhesive composition.
For the production of the interior brand, birch or alder veneer is usually used.
Exterior plywood must have at least one layer of softwood.
Resistance to moisture
Interior plywood may swell when humidity increases, but after drying it will return to its shape without damage. Sheets of this brand can be used for outdoor work. It is used to cover structures in the manufacture of gazebos, baths and other buildings.
Urea glue used in the manufacture of interior plywood begins to break down at high humidity. This leads to the fact that the plywood sheets are deformed, stratified. After drying, they do not recover. This plywood is intended for use only inside the house, but preferably not in kitchens and bathrooms.
Interior plywood consists of wood veneer and urea resin, it is harmless.
Exterior contains toxic formaldehyde, which is released during operation for a long time. The amount of harmful vapors increases with increasing temperature and humidity.
According to this indicator, exterior plywood is ahead of interior plywood. Exterior sheets are resistant to mechanical damage, well withstand bending and tear deformations.
Moisture-resistant plywood Exterior is resistant to rot, wear-resistant, durable. It is used for construction and exterior finishing works, the manufacture of frame structures, fences, timbering, and roofing works. They make garden furniture and outdoor advertising out of it
Interior plywood is the most suitable material for interior work and furniture manufacturing. Plywood sheets are easy to process and have good mechanical strength. It can be used for flooring, as a base for parquet or laminate. A flat surface will provide excellent conditions for laying floor coverings. Various structures such as partitions and arches are made of this material. Smooth plywood sheets are used for covering walls and ceilings in residential and office buildings.
When choosing a building material, you need to decide what is more important, strength or safety. Exterior plywood emits toxic substances, has increased strength, and is not used for the manufacture of furniture and interior details. Interior plywood is less durable, unstable to moisture, and safe.
