  • 3. Main functions of walls 1.Strength 2.Stability 3.Weather exclusion 4.Thermal Insulation 5.Sound Insulation 6.Durability 7.Fire resistance 8.Appearance Part of a cavity wall with the internal skin removed to expose the Insulation
  • 4. CAVITY WALL: • Cavity walls consist of two 'skins' separated by a hollow space. • The skins are commonly masonry such as brick or concrete block. • Masonry is an absorbent material, and therefore will slowly draw rainwater or even humidity into the wall. • The cavity serves as a way to drain this water back out through weep holes at the base of the wall system or above windows, but is not necessarily vented
  • 5. CAVITY WALL INSULATORS : • Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer
  • 6. CAVITY WALL INSULATORS : • The Government regards cavity wall insulation as one of the most effective energy saving measures that you can carry out to your home and as well as saving you money it helps reduce emissions of carbon dioxide, the main greenhouse gas causing climate change. • This is because up to 35% of the heat loss from your property is through the walls.
  • 7. Return corner of a cavity wall in stretcher bond including wall ties and DPC
  • 8. WALL TIES : • Wall ties ensure that the wall leafs do notWall ties ensure that the wall leafs do not part away from each other, effectivelypart away from each other, effectively splitting the two leaves. The normalsplitting the two leaves. The normal spacing of the ties is laid down in thespacing of the ties is laid down in the Building Regulations.Building Regulations.
  • 9. Wall Ties There are a large variety of different types of wall ties, but they all have two basic requirements of:- 1 .Tieing the outer and inner leaf of the cavity wall together. 2 .Prevent moisture passing from the outer to the inner skin of brickwork.
  • 10. Cavity walls in block construction
  • 11. Cavity walls in brick construction with insulation
  • 12. Advantages of Cavity walls.Advantages of Cavity walls. • The moisture cannot enter from outer wall toThe moisture cannot enter from outer wall to inner wall , since there is no direct contact.inner wall , since there is no direct contact. • Provide good insulation aganist sound.Provide good insulation aganist sound. • Protection aganist efflorescence.Protection aganist efflorescence. • Proves economical during construction.Proves economical during construction. • Load on the foundation is reduced.Load on the foundation is reduced. • Reduction of heat transfer ,since air layerReduction of heat transfer ,since air layer between leaves acts as non-conductor ofbetween leaves acts as non-conductor of heat.heat.
