The benefits of UPVC windows and doors


The combination of energy efficiency and soundproofing provides a better room climate that can be enjoyed every time of the day at any day of the year.Air-conditioning can be reduced while the room temperature stays evenly throughout.


UPVC is an ultra-light but sturdy material that can be equipped with various types of multi-locking systems. The combination with double or triple glazing also lowers the risk of intruders to break in.


The UPVC profiles with two or three seals work in combination with the double glazed window panels to decrease the amount of noise that can pass into your home. WOHNRAUM UPVC windows and doors can reduce external noise by up 45dB, depending on the glass specification and surrounding building materials.


Most windows and doors only come in limited colors. WOHNRAUM UPVC Windows and doors are now available in 30 different colors and decors that even imitate natural wood grain.


Green building technology and energy efficiency plays a big part in the future of construction. UPVC is a low conductor of heat and in combination with insulated double glazing, it is the ideal window technology for now and the years to come.


The average life span of UPVC windows can range between 40-80 years and are made from mostly recyclable materials to sustain minimal long-term impact on the environment.


UPVC frames for windows and doors are made from fire rated materials preventing external fire spread.


WOHNRAUM UPVC windows always come with insulated Low-E double or triple glazing. The Low-E coating, a metallic coating on the inside of the glazing unit, has the ability to keep the temperature of the surface of the glass facing the interior very near to that of the room itself, regardless of outside temperature. Low-E glazing also reduces color fading of interiors like furniture and flooring,


UPVC windows and doors do not contain and wood parts and are save to use in termite invested areas.


WOHNRAUM UPVC windows have the popular 'tilt and turn' system as standard. In the inwards tilted position, hot air can escape through the top and side openings while turning the window to open fully can quickly ventilate an entire room and is  useful for cleaning or refreshing.


The material is incredibly tough and can cope against the most extreme elements and are not affected by rot and corrosion. It is protected against ultraviolet (UV) rays to prevent the material from fading in prolonged sun and it can be used in tropical climate and locations near the seaside with high salt content.


UPVC is a low maintenance material, unlike natural materials which require annual sanding, varnishing and repainting. Windows & doors made from UPVC can last for decades without any sign of weathering, the only upkeep is a wipe down clean with soapy water to prevent staining and remove grim or dirt.

Low-E glass has a microscopically thin, transparent coating that reflects the unwanted spectrum of the sunlight but allows useful visible light to enter. This protects from unwanted heat and glare but ensures natural colors and a friendly and comfortable environment.

Additional options include: Triple glazing, Laminated glazing (soundproof / secure) and many other options to protect from harmful UV-light, heat, noise and unwanted intruders.

A good insulated window enhances comfort and well-being in your house or workplace.
