Green Building Product

VEKA India is committed to provide world class window & door systems to the Indian customers. Our endeavour is to provide products which are not just the best in performance, but also safe and minimize the impact on our environment. In continuation of the same objective we are pleased to announce that our entire range of upvc window & door systems is not only Lead Free as well as comply worldwide norms. All VEKA Profile Systems for windows & doors are not only conformed to strictest of International standards such as AAMA (American Norms), EN (European Norms), BS (British Standards), DIN (German Norms) & LEED (Leadership in Energy Efficiency and Design) as well as meets SHGC standards specified by IGBC (Indian Green Building Council).

All VEKA Products are with special Tropical Mix to suit Indian Climate. In Europe, Extrusion Companies have to use a certain Percentage of Recycled Raw Material. Normally they use the Recycle Material in the middle of the Profiles and make a layer of fresh new Raw Material around this on all sides. The fresh new Layer is now normally Lead Free but the Recycle Material will have still Lead in it, as this material comes from old Windows and there is no way to separate Lead free and not Lead free. Profiles VEKA produce in Asia do not use this Technology, so ours are totally lead free.

What makes a product green?
Certain products, particularly those that deal with energy, are not inherently green but can be used in ways that enhance the environmental performance of a building. For example, a dual-pane, low-E uPVC window may not be green in terms of its material components or manufacturing process, but if used strategically it can reduce energy use (heating & cooling) by maximizing the collection of winter sunlight and blocking out the summer sun.

Building materials have multiple impacts on the environment, both positive and negative. One common way to assess these impacts is through Life Cycle Assessment (LCA), which considers the full range of a product’s environmental impacts, from resource extraction to manufacture and then through installation and ultimate disposal. This type of analysis allows for comprehensive and multidimensional product comparisons.

UPVC is the world’s most versatile plastic. Because PVC resin can be combined with many additives and modifiers, uPVC can meet the requirements for products in many industries. UPVC is chosen over other materials because of its low cost, versatility and performance properties. UPVC is strong, durable, abrasion and moisture resistant; withstands rust and corrosion; is electrically non-conductive and has excellent fire performance properties. Because it has been used for more than a half century, it is one of the world’s most analyzed and tested materials.



Formulast Technology is VEKA’s method of formulating and extruding our various uPVC compounds for specific applications. Utilizing the latest computer technology and detailed dimensional drawings, VEKA engineers are able to produce new and innovative products to satisfy the building needs in any geographic region from this amazing material. UPVC products with Formulast technology have a very environment-friendly product life cycle.

1. VEKA uPVC conserves forests: Made from relatively inexpensive PVC means that VEKA uPVC products save our precious forest resources.

2. VEKA uPVC conserves resources: UPVC Windows & doors has a life cycle of min. 20 years vs. wood 7-10 years and will outlast 2 or 3 conventional installations.

3. VEKA uPVC saves oil or gas: Poly uPVC chloride is a plastic with the lowest petroleum content about 43% the remainder is chlorine a common, inexpensive Naturally occurring element.

4. VEKA uPVC protects the air and soil: PVC never needs to be stained, painted, UV treated or water sealed. This not only saves time and money but also keeps potentially harmful fumes and chemicals from being introduced into the air and soil. VEKA uPVC is a versatile material because PVC resin can be combined with many performance additives and modifiers, VEKA uPVC can meet the requirements for products use in any environment.

VEKA windows that are designed for thermal performance can insulate your building while keeping energy costs low. The excellent thermal properties of VEKA windows make energy savings attainable. The specially designed insulating airspaces in uPVC window frames – combined with their low conductivity – make them a formidable barrier to heat transfer. But their environmental performance in other areas also is impressive. Let us take a look at VEKA uPVC window attributes and their relationship to environmental performance.

Designed to conserve energy UPVC window frames and sash corners are fusion welded for maximum strength and protection against air and water infiltration. Tests using the common measure of insulating ability, the U-factor, have shown that VEKA uPVC windows regularly outperform competitive products because of the excellent thermal performance of the frame (shown in table below).

U-Factor Ranges for Various Frame Materials
FRAME MATERIAL U-FACTOR
Aluminum (no thermal break) 1.7 - 2.4
Aluminum (thermal break) 0.6 - 1.3
Aluminum-Clad Wood/Reinforced Vinyl 0.4 - 0.6
Wood and Vinyl0.3 - 0.5
Insulated Vinyl/Insulated Fiberglass0.2 - 0.4

*A measure of the rate of non-solar heat loss or gain through a material or assembly. The lower the U-factor, the greater a window’s resistance to heat flow and the better its insulating value."

Warm air stays inside during the winter and cool air stays inside during the summer. Energy is conserved and money is saved when the furnace and air conditioner don’t have to work so hard to maintain the desired temperature.

Winning combination: high durability, low maintenance VEKA UPVC windows are impervious to rot, rust, corrosion, blistering, flaking and infestation by termites or other insects. UPVC resists attacks by fungus and mildew, and scratching a uPVC window will not require any touch-up. Even better, a heavy rain or simply washing with water and a mild soap is all it takes to keep VEKA uPVC windows clean.

VEKA uPVC profiles can be reprocessed and recycled repeatedly. Scrap is routinely recycled directly back into uPVC products, making it a resource-efficient operation. In fact, 99 percent of the uPVC used by processors goes into a finished product.

VEKA UPVC windows are so durable that the vast majority of them installed over the past 25 years worldwide are still in use and therefore not candidates for end-of-life or post-consumer recycling. When that time comes, however, VEKA uPVC windows – like all uPVC – can be recycled. As with any building product, the key to post-consumer uPVC window recycling is to find a cost-effective way to collect, separate, process and transport used materials to a manufacturer for use in new products.

Inherently fire retardant, meeting stringent fire requirements

UPVC window products, which are based on a naturally fire retardant polymer, have excellent fire performance qualities. UPVC is self-extinguishing when a flame source is removed.

In addition, VEKA uPVC windows are able to meet building codes for ignitability, flammability, heat release, burning rate, flame spread and smoke density. Certain uPVC formulations are able to meet the stringent National Electrical Code of the National Fire Protection Association for insulating electrical and data cables.

Most fire scientists recognize that the largest hazards in a fire are heat and carbon monoxide, an odour-less asphyxiate gas produced in abundance by all organic materials, natural and synthetic. The contribution of the combustion products from VEKA uPVC windows to the overall toxic threat of fires containing many types of combustibles is insignificant.

Made of plentiful natural resources the leading component in the production of uPVC is common salt, an abundant and inert natural resource. More than half of uPVC resin is derived from salt, and natural gas or petroleum makes up the balance. Worldwide, uPVC production accounts for less than 0.3 percent of all annual oil and gas consumption and about 10 percent of annual salt consumption.

Environmental benefits across product life cycle a study by life cycle assessment experts Greg Norris and Peter Yost2 shows the use phase is the most important in terms of a material’s life cycle impact, and counterbalances over time the environmental impact stemming from a product’s manufacture. The material uPVC, because of energy efficiency, thermal-insulating value, low contribution to greenhouse gases, easy maintenance and superior durability of products made from it, provides excellent life cycle benefits.

A study conducted by Franklin Associates shows that VEKA uPVC windows require only one-third as much energy to manufacture as aluminium windows. That study also found that using uPVC over aluminium or steel window frames saves the nearly 2 trillion BTUs of energy per year – enough to meet the yearly electrical needs of 20,000 single-family homes.
