MettleWood Process
Check this out:
Mettlewood is a high-performance structural material made by removing lignin (wood’s natural glue) from wood cells, creating a sponge-like structure that can be compressed for high tensile strength. It’s used in construction, automotive parts, and premium furniture.
Suitable Climates: Engineered for both cold and warm climates; performs well across a wide range of conditions.
Benefits: Excellent fire resistance (Class A), high moisture and pest resistance, low production cost, lightweight, and potential to aid ecosystem restoration.
Drawbacks: Limited data on environmental impact, potentially energy-intensive manufacturing, and possible susceptibility to wood-related issues.
Applications: Used for cladding, facades, beams, columns, and structural connections in buildings.

What is Cross Laminated Timber (CLT)?
Check this out:
CLT is an engineered wood product made by gluing together layers of kiln-dried dimension lumber in alternating directions (typically 3, 5, 7, or 9 layers) to form large structural panels. In rare cases, layers may be parallel. It is used as a substitute for concrete and steel in modern timber construction. faces code limitations for building height in some regions.
Suitable Climates: Performs best in cold climates due to thermal mass and insulation but can be used in warmer climates with proper moisture detailing.
Cold Climates: Excellent thermal performance.
Warm Climates: Requires moisture control to prevent issues.
Benefits: Fire- and mold-resistant (with proper maintenance), structurally stable, lighter than concrete (lower foundation costs), quick to assemble, cost-competitive for mid-rise buildings, reduces on-site labor and waste, and offers good thermal mass.
Drawbacks: Higher upfront costs for low-rise projects, limited design flexibility, transportation challenges, and current code restrictions.
Applications: Used for structural walls, floors, ceilings, roofs, stairs, and elevator shafts in residential and commercial buildings.

Reclaimed Timbers - The Pro's and Con's of Using Recovered Wood
Quick Tips:
Reclaimed wood is lumber salvaged from old buildings for reuse in new construction. It’s carefully deconstructed to preserve the integrity of beams and boards, often called antique wood.
Suitable Climates:
Humid: Best choices are teak and cedar for natural moisture resistance. Seal properly to prevent warping, ideal for bathrooms and kitchens if maintained.
Dry: Oak, maple, cedar, teak, and mahogany resist cracking and dryness. Avoid wood from damp sources. Redwood is a good option for low humidity.
Extreme Temperatures: Thermally modified wood, teak, and mahogany remain stable through temperature swings.
Coastal: Cypress and redwood resist moisture and decay.
Benefits: Eco-friendly, durable, and offers a unique aesthetic.
Drawbacks: High price point and requires high expertise for proper selection and installation.
Applications: Doors and window frames, panels, shelves.
