The PVC as acoustic and thermal insulation

Energy saving and efficiency in the renewal of Windows and doors

When we talk about energy efficiency, it is necessary to take into account the thermal insulation of houses. There are different areas of the home where there are losses of energy; one of the most troubled areas are the Windows and doors, when these are inadequate.

If you have older Windows, with profiles and ineffective glass, it is inevitable to lose energy, as well as comfort and money, as we increase consumption in heating and air conditioning. This emphasizes the importance of having a few good enclosures that allow us to properly isolate housing.

Modern Windows must meet minimum requirements in thermal and acoustic levels, and the PVC has proved to be the best option, which offers greater thermal insulation, since it minimizes the flow of heat from the outside to the inside of the housing and vice versa. In this way, one obtains a significant energy savings, since avoiding the peaks in consumption produced by the use of the heating and air conditioning. Another advantage to be emphasised is his acoustic insulation, ensures that you can enjoy peace of mind in your home, even in especially noisy environments.

PVC has proven to be "the best option" as a material for the manufacture of doors and Windows, according to Rehau.

The values of savings that can be achieved in the renewal of Windows and doors are 64% for frames of PVC, 60% for the wood and 49 per cent for the metallic RPT, according to a study by the Idae

All of these features are demonstrated by different studies, as the calculations of the Idae Institute for diversification and energy saving), which contains the following statement: "today, and given the values of thermal transmittance of frameworks and their ability to accommodate high thicknesses of camera"", the woodwork of PVC from three cameras equipped with grapes including low-e glass are the enclosures with better thermal behaviour". In this study, the values of savings made in the renovation of Windows and doors are 64% for frames of PVC, 60% for the wood and 49% for the metallic TPNS.

Air Comfort is a self-regulating ventilation system developed by Rehau provides a controlled ventilation of the House without having to open the Windows.

Ecological and resistant

In addition, other recent studies have shown that provided homes with PVC Windows can reach very high savings in energy consumption, representing a large reduction in emissions of CO₂ into the atmosphere, highly favourable to the environmental aspect.

Their environmental performance is better than other materials because during its useful life it saves more energy than that used in its manufacture. PVC profiles have a high resistance to external aggressions, a long durability and minimal in the application window maintenance, since it focuses on the movable components (fittings) and elements of seals (gaskets).

Rehau-Euro-Design 70 profiles, made with RAU-PVC, have a constructive depth of 70 mm, 2 together perimeter and a system of five cameras.

REHAU and PVC

REHAU is participating in a study of energy saving for buildings that in the future will represent the basic principles for the construction. "Protect resources for future generations is the philosophy that promotes research and the development of Rehau," says the company.

The design of Rehau is RAU-PVC material, which complies with all requirements for the manufacture of Windows, ensuring the loyalty of shape of profiles, the measures within set tolerances and the constancy of the quality of the material in the supplies. It also guarantees its resistance to weathering and colour stability.
