Materials 3

Question 1

Foundations:

Shallow Foundation Types

Answer 1

Question 2

Foundations:

Construction Sequence

Answer 2

Initial Construction Prep:

• The perimeter blockwork walls are laid.
• 50mm sand blinding layer is spread between the perimeter walls.
• Damp Proof Membrane is laid, ready to receive the rigid insulation layer.

Question 3

Foundations:

Cold Bridging and Thermal Mass

Answer 3

Question 4

Foundations:

Suspended Floor Option

Answer 4

Question 5

Junctions:

First Floor- Platform Frame

Answer 5

Notes:

• First Floor has a double joist for additional strength.
• Insulation is packed around the first floor junction to avoid a cold bridge.
• Breather Membrane from first floor stud frame overlaps ground floor membrane.The first floor cavity is ventilated by a weep vent, that allows water to escape.
• VCL (red line) wraps around the outside of floor plate to maintain the line of vapour control.

Question 6

Junctions:

Eaves- Platform Frame

Answer 6

Notes:

• The insulation is continuous, providing a robust ‘warm roof’ detail.
• Breather Membrane below the roof tiles overlaps the gutter, allowing water to drain.
• The roof cavity is ventilated.
• The VCL (red line) maintains the line of vapour control.
