According to the Carbon Trust, up to 60% of office heat is lost through the building fabric, and approximately 26% through windows. So insulation is a key issue, especially since generation of the escaping heat has undoubtedly involved carbon usage. In summer temperatures, by contrast, the challenge is to reduce heat gain, and keep temperatures constant and here blinds are a much better ecological choice than air conditioning: in most situations blinds would pay for themselves in less than 10 years through the energy savings they provide.
So whether they are to reduce heat loss, or to minimise heat gain, blinds have an important function in providing low cost insulation – at the same time as fulfilling their role in controlling solar glare and providing privacy. High performance fabrics are the secret: often these have reflective surfaces on the window side to improve their insulating properties, and detailed technical information is available for every blind fabric offered with InterLace products. The optimum method for effective energy conservation is electric blinds controlled by a BM system which controls the shading automatically to optimise the energy savings and provide comfort for the occupants.
Transmittance is the amount of light and heat transmitted beyond the fabric. The lower the amount, the greater the efficiency.
Block/reflect is the amount of heat and light that is blocked or reflected. The higher the amount, the greater the efficiency.
Absorption is the amount of heat and light absorbed in the fabric. The higher the amount, the lower the efficiency.
Ultraviolet protection illustrates how protective the fabric is in protecting against ultraviolet rays. The higher the amount, the greater the effectiveness.
