  • Pre 1944 Timber frame

  • Park Homes

  • HMO’s

Solid wall properties are the most energy inefficient
Solid wall properties are the most Energy Inefficient

Cavity Wall properties can lose up to 35% of their heat through external walls

Solid Wall properties can lose 45%+

So

Insulation has a significant role to play in energy conservation for HTT homes


Hard to treat but not impossible
Hard to TreatBut not impossible

The Solution

Insulate and reduce Heat Loss

The Options for solid wall properties

1) - External Cladding

2) - Internal dry lining with thermal board

3) – Internal flexible thermal lining


Solid wall insulation
Solid wall insulation

1.External cladding

Expensive , major alteration to appearance, requires scaffolding

2.Internal dry lining

Expensive , disruptive, reduces room size, service disconnection requires tenant’s relocation

Hard to promote & difficult to manage with multiple trades

Costly, inconvenient requiring high investment of time and money for a low return

Significant carbon savings per property

But

Low net contribution due to small number of installations

3. Internal flexible thermal lining

Inexpensive, versatile, easy to apply with tenants

in - situ.

Can be promoted as an installed product requiring single

contractor or for DIY

Easy to integrate into existing schemes

AT NO EXTRA COST OR WORKLOAD FOR YOU

Substantial net carbon savings due to volume of uptake


Promoting energy conservation

Current Focus shifting to area based schemes

CESP

Systematic approach

Door to door

Advise and engage with householders

PROMOTE

Insulation

Heating system upgrades

Microgeneration

Behavioural change

All quite expensive for residents of HTT

Purple Market research report – April 2009

External wall insulation £88/m2

Internal dry lining £64/m2

Internal flexible lining £25 - £30/m2

Internal flexible lining DIY £14 - £16/m2

Your funding will go further, if you have any and/or

it will be easier to promote to ATP residents
