The Code for
Sustainable Homes is driving for a better living environment,
energy efficiency and a house which reduces its CO2 emissions. When
building internal walls there are many things to consider,
including: sound proofing, heat loss, moisture defence, air
tightness and the use of environmentally friendly, sustainable
Masonry walls that need to support the first-floor structure
should rise from the foundations as load-bearing walls and be tied
into the external structure as it's built. Lightweight, recycled
content, 100mm thick blocks are a preferred sustainable option.
Insulation and airtightness
These two elements are linked because they both have a profound
effect on the annual rate of carbon emissions from a new build
home. Well insulated and airtight internal walls will produce a
more energy-efficient building. An air- tight build is now a
requirement of Building Regulations and to comply you must achieve
a certain level of airtightness - known as the Target Energy Rating
(TER) - or higher; once achieved, it is known as the Dwelling
Energy Rating (DER).
When building internal walls you must be vigilant and look for
gaps to be sealed effectively. Sealants and expanding polyurethane
foam fillers are ideal for this. Ventilation is also very
Sound, moisture, fire
Internal walls can be built with a framework of sustainable
timber (50 x 100mm FSC softwood is a preferred choice) and will
require finishing with plaster or plasterboard.
Jewson offers a full range of plasterboards for all room type
situations, sound block and high density sound absorbing
mineralfibre slabs for bedrooms, moisture defence boards for
bathrooms and fire defence boards for kitchens.
- Use quality certified treated timber when building stud walls.
You'll appreciate the quality.
- Metal studs are less environmentally friendly, but they do save
a lot of time.
- Solid or well insulated stud walls give you great sound
protection - even better if sound bloc plaster boards are
- Sound bloc, moisture resistant and fire retardant plaster board
make the living environment a safer and more comfortable
