Sustainable Building,
Products and Skills

Many modern building materials and practices may be detrimental to the environment creating unnecessary or harmful waste products and a larger carbon footprint than is necessary. Rain Wind and Sun is striving to make all work as sustainable as possible, by sourcing goods made from renewable sources and obtained as locally as possible. This leads to far less environmental impact.

Roofing plays a key role in maximising the energy efficiency of your home by preventing heat loss. It can also be used as a habitat for wildlife. Green roofs offer many advantages, and they benefit the environment through their positive effects as well as being aesthetically pleasing.

Loft and Wall Insulation

Loft Insulation

Loft and Wall Insulation are widely recognised as the most effective energy efficient measures that can be installed. Heating can be turned on less often and for shorter periods, as the heat is retained for longer. There are many different types of insulation available in the building industry, all with their own characteristics depending on whether they maximise energy efficiency and reducing your heating cost, or create the lowest amount of environmental impact.

Wall and Floor Construction

There is an increasing number of sustainable materials that can be used in wall and floor construction, a chief example of this in wall construction ~ using thermalite blocks. These are created from 80% recycled materials offering high thermal insulation and consequently lower energy consumption for heating of buildings. Sonae chipboard is a versatile product for flooring and is created from 98% recycled wood waste.

Wall finishes, Mortaring and Rendering

There are a number of alternatives to the traditional plasterboard that is found in most modern homes including Claytec plasterboard. This is composite board consisting of clay, reed and hessian. It is also compatible with all lime products. Lime-based plaster, mortar and render may be used in much the same way as traditional cement-based products. It does however create much lower CO2 emissions during production and CO2 actually combines with lime during its lifetime, unlike cement.


Timber is the single most sustainable construction material available, provided it is sourced in a responsibly-managed fashioned. Renewable wood can be sourced for almost any type of carpentry project, whether it is sawn timber for stud work or a sustainable worktop.

Eco Paints

Conventional synthetic gloss and emulsion paints contain solvents derived from crude oil and non renewable resources. The waste produced from creating these types of paints is extremely high. In the worst cases synthetic paints may produce 10 times more waste that its final product value. Eco paints is a range of glosses, emulsions and varnishes that are completely solvent-free. The solvents that are found in most conventional paints may cause many health and irritation problems, including asthma, headaches and both skin and respiratory allergies. These paints are also extremely good for low ventilation rooms as they give off little to no intoxicating smell. Eco paints are also far more sustainable, as they are made from renewable resources, and as the main components are bio-degradable there is not the same waste issue with disposal as with traditional paints.

Eco Garden Landscaping

Landscaping should include an attractive environment that is in balance with the local climate and requires minimal resource inputs, such as fertiliser, pesticides and water. Sustainable landscaping begins with an appropriate design that includes functional, cost efficient, visually pleasing, environmentally friendly and maintainable areas. Goals could include saving water or implementing and using a compost strategy.

Drainage and Water Conservation

The majority of guttering and drainage systems are made from PVC which is particularly damaging to the environment (from toxins during production to the end-of-life disposal). Steel is an excellent alternative for guttering due to its high recycled content and durability. Other drainage strategies available are storm-water management and rainwater harvesting.
