Types of Plywoods used in Interior Designing

Introduction:

Plywoods play a major role in designing your interiors. Without plywood, the interior designing industry wouldn’t have touched the peak where it is now. Innovation of plywoods even reduced deforestation by 17%. 

Before Plywoods, homeowners and carpenters used the hardwood for their furniture and tables. Mother nature always allows us to innovate new concepts whenever it is needed.

The same way Plywood’s innovation created an evolution in the carpentry and interior designing industry. Our Interior Designers in chennai have been working on this nature saving project for the past 8 years

Here are the reason why plywoods is eco friendly

  • Plywoods are manufactured from sustainable forest, which is nothing but a managed system. So we can measure the tree cut and seed planted for deforestation. 
  • Reduces wastage, if you cut the hardwood the chances of wastage are high. But in the case of plywood even the wastage can be converted into a finished product. (Note: They just peel the timber rather than cutting)
  • Veneer is the most environmentally friendly product, plywood manufactured from veneer is very safe.
  • Plywoods give you more output. Since the wastage is very limited the plywood industry makes a predictable output.

Types of Plywoods which are majorly used in Interior Designing Industry

  • Hardwood
  • Softwood
  • Aircraft Plywood
  • Exterior Plywood
  • Overlaid Plywood
  • Lumber Plywood
  • Marine Plywood
  • Structural Plywood

Plywood comes with various sizes and shapes, each type is manufactured to cater different products. Here we will go deeper about each plywood type.

Plywoods types depending upon the thickness, the categories are 3 Ply, 5 Ply and Multiply

3 Ply – 3 Ply is the most commonly used plywood which has 3 layers of veneer which is used for decorative purposes.

5 Ply – 5 Ply has 5 layers of veneer and it is harder which can withstand weight as well. Interior designers use 5 ply for Dividers, Furniture, Wardrobe etc.

Multiply – This type of plywood is not used for interiors, because of its toughness multiple plywoods will be used in exterior works. They are ultimately very strong which can withstand any damages caused by nature.

Softwood:

Softwood might look like hardwood, but interior designers consider it as plywood. This plywood is manufactured from Pine, cedar and redwood. 

  • Used for some temporary construction work, they don’t last for years so softwood usage is temporarily used.

The Structure of softwood comparison between pine and spruce are

  • Density +/- 20%
  • Strength +/- 40%
  • Modulus of Elasticity +/- 35%

Load Bearing Capacity & Stiffness of normal Softwood (Comparison between pine and spruce softwood)

  • Moisture Content – Pine 12 and Spruce 12
  • Density by kg/m3 – 420 Pine and 380 Spruce
  • Tensile Strength – 104 Pine and 90 Spruce
  • Bending Strength – 87 Pine and 75 Spruce
  • Thermal Conductivity – 0,25 pine and 0,24 for spruce

Hardwood:

Hard Plywood is similar to 3 to multiply plywood. The purpose is to withstand some heavy duty. Hardwood is manufactured from Birch, Oak, Maple, Walnut, Poplar.

Interior designers usually manufacture furniture, musical equipments, dividers, heavy frames etc.,

The Structural of hardwoods, comparison between Maple, Oak and Rosewood

Density Kg/m3 – 620 to 750 (Maple)

Oak Kg/m3 – 595 to 890 (Oak)

Rosewood kg/m3 – 790 to 870

Aircraft Plywoods:

Plywoods are not only used in interior designing and furniture industry, aviation use plywoods for constructing planes. The only reason they use it is because they want something very lite weight and should have stronger strength.

Aircraft plywoods are the highest grade plywoods, usually mahogany tree plywoods are used for aircraft. 

Density of Mahogany Plywood

Density: Kg/m3 – 490 to 850

Density: g/cm3 – 0.49 to 0.84

Density : lb/ft3 –  30-52

Depending upon the aircraft need, the aviation industry will use spruce, Birch and others.

Exterior Plywoods:

Exterior plywood is not easy to manufacture. These plywood must have weather and water resistance. So Manufacturers use multiple manufacturing techniques to make the exterior plywoods stronger and heavier. They must withstand wind, rain, sunlight and sometimes snow as well. 

The exterior plywoods usually have multiple veneer layers which are tightly glued and compressed. Manufacturers usually supply the plywood based on the geographical locations. For example if the area is completely harsh they supply oak so that this material can withstand mildew and mold. 

Marine plywoods:

The most important feature a marine plywood possesses is waterproof. The Marine industry certifies them as marine grade plywood. 

These plywoods are manufactured with water resistant exterior glue. Usually normal plywoods use glues for the veneer layer. In marine plywoods the water resistance glue will be applied outside the plywood as well. It’s a complete zero air lock plywood which can withstand for many years. 

Marine plywood is always manufactured in “B” Grade Plywoods. At the same time marine plywood is free from mold, termite and other insects. 

The most important feature a marine plywood should possess is it should not have any knotholes. 

Technical Specifications of Marine Plywoods:

Moisture Content – 10 to 15%

Glue Strength – 150 to 180 kg

Resistance to Water – 850 to 1100 N

Tensile Strength  – 85 N

Blockboard Plywoods:

It stays neutral because these materials can be either called plywoods or softwood. The process is similar to other plywood. Veneers are covered both the side of the plywood and in the middle there is a thick piece of wood. 

Block boards can withstand a reasonable amount of pressure. These plywoods are usually used for cabinets, shelves etc., The normal thickness of blockboard plywoods ranges from ⅜ to 1 3/16 inches. 

Moisture Resistant Particleboard:

M-R Particleboard are used in water resistant area 

Here are following places where Moisture resistant particleboard are used

  • Flooring for Artificial Waterfall
  • Cattle flooring 
  • Theatres and hospitals flooring

Conclusion:

Interior designers across the world use plywood for their projects. When we compare the cost, plywood cost is very reasonable and withstand for many years. You can make Holistic Design as well

Plywoods are very cost effective, where they can reduce wastage as well.
