Step 1
strip foundation
Answer
A strip foundation is a continuous strip of concrete that supports the load of a structure, typically used for walls.
- Design and Materials: This foundation is commonly made from reinforced concrete, providing adequate strength to support walls.
- Function: The walls transfer loads down to the foundation, which distributes them evenly across the underlying soil. It is particularly effective in areas where the soil quality is good.

Step 2
wind turbine
Answer
Wind turbines are devices that convert wind energy into mechanical energy and subsequently into electricity.
- Sustainability: They provide a renewable energy source, reducing reliance on fossil fuels.
- Working Principle: The wind turns the blades, which then activates a generator to produce electricity. Smaller versions can be utilized in residential areas.

Step 3
wall tie
Answer
A wall tie is a metal connector used in cavity wall construction to maintain stability and structural integrity.
- Function: These ties help bond the outer and inner walls together, preventing them from moving apart.
- Types: Traditionally made of stainless steel, they are also available in various materials to reduce thermal bridging.

Step 4
facade board
Answer
Fascia boards are horizontal boards that are placed at the intersection of the roof and the exterior walls of a building.
- Protection: They safeguard the roofline from weather damage and provide a finished look to the roof.
- Materials: Commonly made from wood, PVC, or aluminum, they offer durability across different environmental conditions.

Step 5
cordless jigsaw
Answer
A cordless jigsaw is a versatile power tool used for cutting various materials in straight or curved shapes.
- Operation: It is powered by a rechargeable battery, allowing for portability and ease of use away from power sources.
- Applications: Useful for crafting and construction, it can cut materials like wood, metal, and plastic.
