Insulation & Glazing
       
       

 

     We specified that the rate of heat loss from the building should be no more than 5kW (kilowatts) when the temperature inside is maintained at 20ºC and the temperature outside is -1ºC.

To achieve this we used:

Roof
Layers from the outside: reclaimed natural blue slate, Tyvec breathable building paper, 300mm Warmcell recycled newspaper insulation, 12.5mm foil-back plasterboard.

Ground Floor Walls
100mm Bradstone external cladding wall from the original building, 50mm cavity, Tyvec building paper, 25mm bituminous softboard, 250mm Warmcell insulation, 12.5mm foil-back plasterboard.

First Floor Walls
25mm untreated, green, local larch board, Tyvec building paper, 25mm bituminous softboard, 250mm Warmcell insulation, 12.5mm foil-back plasterboard.
     

Floors
25mm reclaimed maple flooring, breathable building paper, 150mm rockwool insulation.

Glazing
Velux skylights with 22mm Pilkington K high performance low-e double glazing.
English larch preservative-free EcoPlus stormproof windows with high performance low-e double glazing.
Reused double-glazing windows have low-e secondary single glazing sliding panels to form triple glazing.

 
     

What you can do
     

Priority should be maximum insulation and draft-proofing before upgrading glazing.

Energy Efficiency
The majority of energy used in the home is in water and space heating.
Many energy efficiency measures start saving you money in less than a year!
