The porch is constructed of a brick base of
approximately a meter in height, and upvc windows around this rectangular brick
base, with a pitched slate roof.one radiator that is fed off the gas central
heating system is located inside thisconservatory. The door isa upvc unit.
A test hole is to be inserted in the roof
to determine whether or not a layer of insulation was laid during the
construction of the conservatory.
If none is found.A small loft hatch will
need to be created in the ceiling of the conservatory toaccess the apex space and
a layer of 300mm Mineral wool is to be evenly spread throughout the floor plate
of the roof.
This will limit heat loss from the conservatory,
it will further create a cushion of warm air inside the conservatory to repel
any loss of warm air from the inner home into the conservatory. Also the
conservatory will act as a ‘decompression chamber’ between the warm home and
the colder outside temperatures.
The entrance has a wet patch on left hand
side on entry, this is creating a cold bridge, from the penetrating moisture,
and from a thermal view point will be cooling the house.
The source of the water ingress here is
lack of sufficient drainage, and capillary rising action of the water.
Stop water ingress by creating sufficient
drainage outside and re pointing with chemical treated cement or silicone
system to water proof and block rising action.
18-25 % of heat loss can occur through
walls, the current construction of the walls will allow this range of heat loss,
and a fabric first approach to this retro fit will require some form of
Two types of wall insulation are
This process involves installing insulation
on the inside of the property, generally the profile consists of 2-5 inches of
a mineral wool and or foam boards that are covered with a decretive finish that
can be plastered or papered to match the inside of the house.
of internal insulation
Cheaper than external insulation
Easier and cheaper to install –can be
installed one wall at a time
Intelligent vapour control layer should be installed,
to tackle the loss of breathability of building fabric
A single nail driven by residents can
disturb the system.
This process involves attaching the
insulation materials to the outside of the home, encasing and enveloping heat
inside, generally the insulation material is attached to the outside brick or
masonry face, the foam insulation board is then covered over, however in this
scenario a host of external finishes are available from custom brick finishes
to rain screens, thus potentially making this a perfect choice to compliment
the environmental protection policy an example of this would be in the form of
a skin of Victorian brick finish in the same colour and dimensions as original
Improves weather protection
Provides noise insulation
It’s easier to take care of thermal bridges such as exposed concrete
frame or window sill
Preserves the value of the thermal mass of the walls in regulating
If there is not sufficient roof overhang, the top of the extended wall
must be sloped, weatherproofed, and guttering fitted
May need planning permission – ask the planning department (conservation
Downpipes and other projections, or service entry points, must be dealt
The damp proof course and window trickle vents must not be covered
