Green building product
what makes a product green?
Building materials have multiple impacts on the environment, both positive and negative. 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.
Made from PVC processed using relatively inexpensive eco-friendly methods, VEKA products do little to no harm to the Earth’s forests.
uPVC Windows & Doors have a life cycle of minimum 20 years. In comparison to the 7-10 year lifespan of wood, uPVC will outlast 2 or 3 conventional installations.
saves oil or gas
Poly uPVC chloride is a plastic with the lowest petroleum content at about 43% while the remainder of its composition is chlorine, an inexpensive, naturally occurring element.
projects 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 window systems are made energy efficient, due to their unparalleled thermal insulation properties. The specially designed insulating airspaces in uPVC window frames combined with their low conductivity make them a formidable barrier to heat transfer.
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).
|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 vinyl||0.3 – 0.5|
|Insulated Vinyl / Insultaed Fiberglass||0.2 – 0.4|
U-Factor Ranges for Various Frame Materials
*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.” Source: Residential VEKA windows: A Guide to New Technologies and Energy Performance, Second Edition, J.

VEKA uPVC windows are so durable that the vast majority of them, installed over the past 25 years worldwide, are still in use. 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.
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 odourless, 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.
VEKA uPVC’s high-durability and low maintenance windows are impervious to rot, rust, corrosion, blistering, flaking and infestation by termites or other insects. uPVC resists attacks by fungus and mildew, and scratches will not be prominent.
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.
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.
