  2. Agenda • Introduction • Solutions • Case Study - Sempatap • Summary • Questions

  3. Introduction - What is a Hard to Treat Home? • These types of property often fall into one or more of the following categories: • Solid wall construction • No loft space • Off the mains gas network • Non traditional construction • Non standard cavity

  4. Introduction – The facts about Hard to Treat Homes • HTT properties tend to be more difficult and expensive to improve in terms of providing adequate insulation and heating. • Over 50% of fuel poor households live in HTT homes • There are around 9.2 million dwellings that can be considered HTT (43% of the housing stock) • 6.6 million properties have solid walls (31% of the total housing stock) • Of the 326,000 high rise flats in England 48% have solid walls.

  5. Introduction – The facts about Hard to Treat Homes • HTT homes account for 43% of stock but actually emits over half the CO2 from all homes. • Over half of the HTT stock is in the private sector. • 65% of PRS is HTT

  6. Introduction - What is a solid wall? • 9” masonry walls and other non-traditional construction types such as single leaf masonry, >9” walls (e.g. thick stone walls) • concrete walls, metal or timber panels and some mixed wall types (e.g. Where the ground and first floors are constructed of different materials) • BRE estimate that around 7% of unfilled cavity wall stock cannot receive CWI. • High rise flats (at least 6 storeys high) – esp. 1953-1972

  10. What are the solutions? Internal Wall Solutions Typically consists of either dry lining in the form of flexible thermal linings available in 1 metre by 12.5 metre rolls, laminated insulating plasterboard (known as thermal board), or built-up systems using fibrous insulation such as mineral wool held in place using a studwork frame.

  11. External Wall Solutions Comprise of an insulation layer fixed to the existing wall, such as a protective render or decorative cladding. Dry cladding offers a wide range of finish materials that can be used – timber panels, stone or clay tiles, brick slips or aluminium panels. What are the solutions?

  12. Other Solutions A majority of HTT properties will benefit from the provision of draught proofing. Some HTT homes have a standard loft space that can be insulated. Loft spaces with restricted access/headroom can often be insulated using blown cellulose which is made from recycled newspaper. Properties with a cellar/basement can have the underside of the floorboards insulated. What are the solutions?

  14. Case Study – Internal Solution The problem A solid wall Victorian terraced property with an uninsulated converted loft space. The solution Sempatap is thermal insulation on roll which is applied like wallpaper and at only 10mm thick does not cause significant disruption during installation. This product can be applied to ceilings as well as walls and provides a solution for properties without a loft space as well as those with solid walls. It can also be applied to the underside of floorboards in a cellar/basement.

  15. Case Study – Internal Solution The product is applied using a special adhesive using a roller or brush and can be easily cut to size using wallpaper shears or scissors. Once the product has been applied it can be painted, papered or even tiled. The manufacturer of this product expect it to have a life expectancy of 30 years. Due to the flexibility of the product it can be used on uneven walls and irregular surfaces and can be used on sloping walls and ceilings in converted loft spaces. The product is only applied to the exterior facing interior walls of the property.

  17. Summary- key points • There are around 9.2 million HTT homes • 6.6 million properties have solid walls • There are solutions for HTT homes • Internal/external insulation • Loft insulation • Draught proofing • Solid wall insulation can save up to £500 a year and around 2.5 tonnes of carbon. • Draught proofing can save up to £30 a year and around 150kg of carbon. • Loft insulation can save up to £205 a year and around 1 tonne of carbon.
