Marine Plywood Vs. Multiwood

The comparison between Marine Plywood (IS 710 grade) and Multiwood depends on the application. Here's a detailed comparison across key parameters:

 1. Composition

Marine Plywood (IS 710 Grade):

Made from high-quality hardwood veneers bonded with BWP (Boiling Water Proof) phenol-formaldehyde resin.

Has layers (plies) of wood pressed together in cross-grain structure.

Multiwood:

Not wood-based. It is a uPVC (unplasticized polyvinyl chloride) or polymer-based sheet.

Manufactured using plastic composites and calcium carbonate; doesn’t have any natural wood layers.

🔹 2. Water Resistance

Marine Plywood:

Extremely water-resistant, suitable for high-humidity or coastal environments.

Still, can absorb water over time and needs sealing at edges.

Multiwood:

100% waterproof, termite-proof, and does not absorb moisture.

Preferred in bathrooms, modular kitchens, or damp areas.

Winner: Multiwood (for moisture-heavy environments)

3. Strength and Load-Bearing Capacity

Marine Plywood:

Stronger structurally; better load-bearing capacity.

Holds screws and nails better.

Multiwood:

Not as structurally strong.

Can warp under heavy load or over long spans.

Winner: Marine Plywood (for structural or load-bearing use)

 4. Workability

Marine Plywood:

Works like natural wood. Easy to saw, screw, paint, or veneer.

Multiwood:

Can be cut and screwed, but tends to chip or crack if not handled carefully.

Needs special fasteners in some cases.

Winner: Marine Plywood (for carpentry or detailed finishes)

5. Durability & Lifespan

Marine Plywood:

Can last 15–25 years with proper sealing and care.

Vulnerable to termites if untreated.

Multiwood:

Inert to termites, rust, or rot.

Durable in damp areas but can turn brittle over time if exposed to harsh sunlight.

Tie: Depends on exposure — Marine ply (for strength & finish), Multiwood (for moisture & termite resistance)

 6. Cost

Marine Plywood:

Generally cheaper than Multiwood for the same thickness.

Multiwood:

More expensive, especially for thicker boards.

Winner: Marine Plywood (budget-friendly)

 7. Eco-Friendliness

Marine Plywood:

Uses natural wood, but involves tree felling.

Formaldehyde content can be a concern in cheaper brands.

Multiwood:

Synthetic and non-biodegradable; not eco-friendly.

Winner: Marine Plywood (relatively better for sustainability)

 When to Choose What

Use Case Recommended Material

Modular kitchen in dry zones Marine Plywood (IS 710)

Bathroom cabinets Multiwood

Wall panels/furniture near water sources Multiwood

Beds, tables, wardrobes Marine Plywood

Long-term heavy-duty furniture Marine Plywood

Zero-maintenance outdoor cabinets (shade only) Multiwood

Verdict

Marine Plywood is better for structural strength, finish, long-term use, and custom woodwork.

Multiwood is better for wet areas, low-maintenance needs, and termite-proofing.

Once there were wolves ~ Charlotte McConaghy (46 of 2024)

 


Inspired by the Yellowstone Wolf Reintroduction project, this is the story of Inti Flynn who is on a similar project in Scotland. Brilliant plot combining climate crisis, psychological issues and a murder mystery. 261 pages, but lot of information, going to and fro, past and present. 

Inti Flynn has come to the Scottish Highlands to lead a team of biologists on a mission. They are releasing a pack of fourteen gray wolves in an attempt to restore the ecological balance that has been badly upset by lumbering and killing of the wolves. The local rural community is up against the project as they fear for the lives of their sheep and themselves too, for wolves are a much maligned and feared of animals.

Inti and her twin sister Aggie grew up splitting their time between their father, who was a lumberjack turned naturalist in Alaska and their police officer mother in Australia who deals with crimes against women day in an out. The intense connect that Inti and Aggie has with nature is directly related to their childhood that was spent with their father.

“The forest has a beating heart we can’t see,” Dad told us once. He lay flat on the earth and we copied him, placing our hands on the warm ground and our ears to the underbrush, listening, “It’s here, beneath us. This is how the trees speak with and care for each other. Their roots tangle together, dozens of trees with dozens more in a web that reaches on forever, and they whisper to each other though their roots. They warn of danger and they share sustenance. They’re like us, a family. Stronger together. Nothing gets through this life alone.” He smiled then, and asked, “Can you hear the beating?” and we could, somehow we could.”

This para touched my heart, took me back to my childhood.

All the characters have shades of grey, and there are specific and plausible reasons for what they have done, have gone through. Aggie is catatonic, Duncan, the local police chief is obviously hiding some past trauma, Lainey, the local sheep farmer Stuart’s wife is being abused by her husband regularly but everyone seems to turn a blind eye towards it. The mysteries are solved one by one as the wolves are slowly reintroduced and start acclimatizing themselves to the wilderness. Inti and her team walks on a tightrope, for they know one misstep and the wolves would all be killed. Things come to a head when Stuart disappears. Foul play is suspected, Inti knows what happened, but she cannot disclose it to anyone. It is when Duncan is attacked in a similar manner that even Inti figures out what exactly was happening.

Inti is afflicted with “mirror touch synesthesia,” a rare condition that causes the individuals to feel the same sensations that another person feels. Whether it is the wolves, Aggie or Duncan, the effect on Inti is devastating.

Like the trees, we cannot remain isolated. our redemption is in our connections, in understanding and supporting each other, and turning to each other to find solace, peace and redemption.

Aggie had to go through a lot from her surgeon husband,  there was no end to the pain, suffering and how much the sisters wanted to protect each other and be with each other. 


Then There was a mother, who realise there is more kindness in this world but we tend to focus on the bad. Children who fail to understand the signs. A childbirth in the forest and a horse helping through.  A daughter following the footsteps of her father and Gone Home  👣 Forest.

Wolves might very well be one of the most misunderstood species of animals. They are considered wild, yet they are so close to us, humans. We too were wild once. And we still are, just that we have learned to camouflage it well. McConaghy makes us live with the wolves, feel their thoughts and emotions.

 Long before they killed the wolves, they massacred over 300 native americans and displaced several thousand to establish the yellowstone NP in 1872.

Migrations ~ Charlotte McConaghy (48 of 2024)

 


There is nothing so disturbing as a creature born to flight being bound to dull lifelessness.
--------------------------------------
A nameless sadness, the fading away of the birds. The fading away of the animals. How lonely it will be here, when it’s just us.

Franny Stone has always been the kind of woman who is able to love but unable to stay. Leaving behind everything but her research gear, she arrives in Greenland with a singular purpose: to follow the last Arctic terns in the world on what might be their final migration to Antarctica. Franny talks her way onto a fishing boat, and she and the crew set sail, traveling ever further from shore and safety. But as Franny’s history begins to unspool―a passionate love affair, an absent family, a devastating crime―it becomes clear that she is chasing more than just the birds. When Franny's dark secrets catch up with her, how much is she willing to risk for one more chance at redemption?Epic and intimate, heartbreaking and galvanizing, Charlotte McConaghy's Migrations is an ode to a disappearing world and a breathtaking page-turner about the possibility of hope against all odds.

This dystopian story spans Australia, Ireland, Antarctica, and all realms of the heart in between. The main character, Franny, seems to unravel as the pages go on. Her tale is told in real time and in flashbacks. Her marriage to Niall is heartbreaking, with one of the central dichotomies being loving, wandering, and leaving. There are truly unexpected twists and turns that left me breathless. It's wrenching to read but ultimately cathartic and triumphant.

She’s frozen and her tent has blown away but after six days Fran has finally banded her third. Her intention is to follow the migration of Arctic terns as they flee their breeding ground in Greenland and head to their winter quarters in the Antarctic Circle. These birds complete the longest migration of any animal and they complete it twice each year, as they’ll head back again in around six months. Their annual milage is calculated to be in excess of forty thousand miles and it can take up to three months to complete each journey. Fran plans to track them on her laptop.  An arctic expedition and a murder mystery too. Exquisite writing and brilliant plot all in 272 pages.
