Importance of insulated double glazing in hot and tropical climate


Are you looking for ways to keep your home cool and comfortable in hot climate? Consider upgrading your windows to double or triple glazed low-e glazing.

Double glazed low-e glazing is a type of window that is designed to reduce the amount of heat that enters your home from the outside. The window has to or three panes of glass that are separated by a gap filled with Argon or krypton gas. This gap provides insulation, which helps to keep the heat out and the cool air in.

Low-e coating is a microscopically thin layer of metal that is applied to the glass. It reflects infrared radiation and blocks heat transfer, which further reduces the amount of heat that enters your home.

In hot climates, double glazed low-e windows can offer a range of benefits. They can help keep your home cool and comfortable, which can reduce the need for air conditioning and lower your energy bills. They can also help to protect your furniture and flooring from fading and damage caused by sunlight.

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.
