Sustainable And Eco Friendly uPVC Windows

uPVC windows are impervious to rust, rot, blistering, corrosion, flaking and infestation by termites or other insects.

Today, plastic rivals traditional materials for windows and frames, providing competitive energy efficiency, aesthetics, design flexibility and price criteria. For instance , polycarbonate plastic—the same material utilized in eyeglasses and known for durability and clarity—is utilized in windows. Shatter-resistant and light-weight , the uPVC product has low thermal conductivity, thus reducing heating and cooling costs though still providing protection against dangerous weather.

The presence of mold can have drastic effects on indoor air quality and therefore the health of these with asthma or hypersensitivity. When uPVC is employed as window dressing, like solid uPVC frames, it serves to assist minimize condensation, thus aiding within the prevention of mold.

A study by an internationally respected lifecycle analysis firm shows uPVC window frames require 3 times less energy to manufacture than aluminum window frames. Beyond that, the utilization of uPVC window frames has been shown to save lots of the US nearly 2 trillion BTUs of energy per year—enough to satisfy the yearly electrical needs of 18,000 single-family homes. the planning of uPVC window frames further enhances energy efficiency by creating chambers within the frame that provide additional resistance to heat transfer and insulating air pockets.

The energy efficiency of uPVC windows and doors can mean less electricity which is employed to heat and funky a home or building which may help reduce the greenhouse emission emissions related to coal-fired power plants. additionally , the low maintenance requirements of uPVC windows and doors eliminate the necessity for paints, stains, strippers and thinners, which may negatively impact air quality.

Low impact, high performance
Thanks to advances in recycling and merchandise innovation, uPVC is now widely known as a sustainable option for the development industry. Old uPVC window frames are often recycled and repurposed up to 10 times without the standard or performance deteriorating. consistent with the Building Research Establishment (BRE), the typical lifespan of uPVC windows is 35 years, which suggests PVC-U offers up to 350 years of high performance, with minimal impact on the environment.

Material property benefits
uPVC is usually erroneously thought to be ‘unsustainable’ because it’s not organic like timber. But being organic is merely one element of sustainability, and a less critical one within the exterior building products market, which by definition needs products to be highly durable, low maintenance and thermally efficient. uPVC is inherently insulant , whereas timber is porous and aluminum may be a conductor (prone to thermal bridging issues, a serious explanation for condensation) On a like-for like basis uPVC is the most thermally efficient material. uPVC is additionally fully recyclable and may be recycled up to 10 times with no material degradation. This provides a bit of uPVC a minimum lifetime of 350 years (source: BRE) Timber isn’t recyclable and is most ordinarily disposed of by burning, which may be carcinogenic. Clearly uPVC may be a sustainable material, and offers better value for money than timber or aluminum.

An environmentally sound option:
• uPVC windows achieve an A rating for residential buildings and an high rating for commercial projects within the BRE Green Guide
• Recycled uPVC offers many years worth of usage
• Reduced environmental impact
• Purposed engineered to supply superior energy efficiency
• Reduced amount of uPVC getting to landfill

Green Point Design, an architectural firm based within the Victorian highland tourist town of Daylesford aims to integrate best practice in energy efficiency and materials utilized in its sustainable building projects and has chosen vinyl windows on several occasions within the past few years.

Principal architect of the firm, Eric Zehrung, described the challenges of a recent house that was a contender for the 2003 RAIA Victorian architecture Awards.

“The design brief involved optimal energy efficiency, but the block posed some challenges that made appropriate dealings somewhat difficult. For instance, it had been steeply sloping, exposed to harsh winter winds, and had limited access to the northern sun. Not all the choices were made easily.” Eric said.

In aiming for a sustainable building, the architects considered issues like embodied energy, durability, and energy efficiency of materials. uPVC windows consistently rate five stars under the Window Energy Rating Scheme.

“For windows we selected uPVC which doesn’t require trees to be hamper , and has excellent thermal performance. In fact timber and aluminum are the opposite options for windows, and sometimes we don’t have a choice. for instance , we designed a house down along the good Ocean road where we discovered that the local cockatoos had a particular taste for cedar – if you used it, they ate it!” Eric explained.

Although not the ultimate winner of the RAIA Awards, Green Point Design’s Daylesford house achieved excellent ratings altogether in categories of the ESD criteria. It received 21 points and five stars within the FirstRate House Energy scoring system – one among the very best scores that the rating service had ever awarded.

“As a policy we never endorse any particular product – we maintain an edge of independence and keep an open mind. Some decisions are difficult to form , though with the windows we had the arrogance that they had excellent physical properties for energy efficiency.”

Green Point Design’s approach may be an exemplar of selection on merit – a principle supported by the Vinyl Council of Australia , where products or materials are selected on the idea of their merits in terms of performance, environmental impact and price for the actual project at hand. Sophi Macmillan, Vinyl Council Chief Operating Officer said, “PVC’s technical properties and life cycle attributes, like thermal efficiency and sturdiness , lend themselves to a spread of products which will positively contribute to sustainability in construction.”

Eric adds, “Some decisions can even be agonising and positively ‘sustainability’ isn’t always clear cut. Only future generations will really know if what we’ve done is sustainable.”
