Coming from the UK where uPVC windows are affordable and the main choice for homeowners.  We were shocked at the high cost of double glazing within New Zealand.  After obtaining various expensive quotes to replace the windows of our own home, we decided to search overseas.  The cost savings were considerable even after the shipping costs were added. On returning to New Zealand we were surprised at the interest and the fact that many homeowners wanted double glazing but could not afford it. This is why we decided to form Affordable uPVC Windows Limited. Bringing affordable uPVC double glazing to N.Z.

New zealand compliant

The CodeMark® Certification Scheme (CodeMark®) is a Building Product Certification Scheme that supports the use of new or innovative products. CodeMark®provides confidence and certainty to regulatory authorities and the market to demonstrate that a building product complies with the National Construction Code (NCC), Volume One and Volume Two. 

(The Scheme operates in both Australia and New Zealand and was developed in Australia by the Australian Building Codes Board (ABCB) and in New Zealand by the New Zealand Department of Building and Housing, Ministry of Business, Innovation and Employment (MBIE). Code Mark® is suitable for any building product or system, but is beneficial for innovative building products and/or systems. The scheme provides confidence and certainty to regulatory authorities and the market through the issue of a Certificate of Conformity.).

Code Mark is an unchallengeable form of product assurance. Building consent authorities (BCAs, usually councils) must accept a product certificate as evidence of compliance with the Building Code, as long as the product is used in accordance with the use and limitations defined on the certificate.

  • Products are certified against criteria set by building control authorities
  • The scheme is an unchallengeable form of product assurance
  • Clear demonstration that the product meets mandatory compliance requirements
  • Provides opportunity to access the market and offers a marketing advantage

R ValuesR Values
What does the R Value mean
R-Value is the rating system used to grade insulation products or a material's insulating properties. The “R” stands for “resistance” and refers to the resistance a material has to heat flow, or temperature conduction. When a product or home has a high R-Value, this means it is well insulated.

All our windows come with toughened low e glass and argon filled as standard, with an R value in excess of the new amendment to:-
" H1 Energy Efficiency for all Housing & Building up to 300 m2".

Advantages of uPVC Profiles?
uPVC (un-plasticised polyvinyl chloride) or rigid PVC is widely used in the building industry and is a low-maintenance product. uPVC is known as having strong resistance against chemicals, sunlight, and oxidation from water. “Un-plasticised” is the modification of PVC by using additives, chemical stabilisers, heat stabilisers such as titanium dioxide and UV Stabilisers. Plastics are relative newcomers as window and door frame materials within New Zealand but are growing in popularity. uPVC is a very versatile plastic with excellent insulating value, the uPVC frames have small hollow chambers inside and this is what helps to reduce temperature gain and loss as well as noise exchange. uPVC window and door frames have great moisture resistance and should have no problems with condensation or draughts. With the uPVC profiles you have a range of colour selection options and surface appearance options with the added use of laminates in modern manufacturing methods. Recent advances have improved dimensional stability and resistance to degradation from sunlight and temperature extremes which make them perfect for the tropical climate. In terms of thermal performance, uPVC frames are comparable with wood, while there are minor differences, depending on the frame construction, however the uPVC does not need ongoing maintenance like timber.
These factors make uPVC an ideal frame material for double glazed windows and doors.

Energy Efficient Windows
Energy efficient windows, also known as energy saving windows, are designed to prevent your heated or cooled air escaping from your home. Their increased insulation reduces your home’s energy usage—and therefore, your bills! while also making your home more comfortable overall.
The Benefits of Energy Efficiency Windows.

Save Money
Customers who install Energy Star windows save an average of 12 percent on their utility costs throughout the year. That means a customer who spends $200 a month or $2400 a year would save $24 a month—or roughly $288 a year. Your savings could be even greater depending on which windows you’re replacing and the climate of your area. In fact, Energy Star studies show that replacing single pane windows with double pane can save between 21% and 31% off heating and cooling costs.

Enjoy Some Peace and Quiet
The same insulating qualities that prevent heat loss in energy efficient windows also help keep sound out, so your home will be more quiet overall. This is good news if you live in a busy neighbourhood with barking dogs, lots of traffic, or any other source of regular noise.

Double and Triple Pane Windows
Energy efficient double pained windows and triple pained windows are made up of multiple sheets of glass sandwiched together with spacers. These multi-layer constructions create air pockets between the layers of glass, which are sealed shut to prevent any air from entering or escaping. Finally, they are filled with different gases to increase their efficiency.
Multi-pane windows are highly effective at insulating homes and are a major improvement over single-pane windows, although they’re more expensive than single pane windows. Still, upgrading your windows is one of the most effective ways to increase your home’s insulation, so the extra price is a wise long-term investment.

Low-e Window Coatings

Low-e or low-emissivity coatings are an effective way to keep heat inside your home in the winter or to keep it out of your home in the summer. These coatings are designed to control the way the heat energy from sunlight moves around. An exterior low-e coating can prohibit the ultraviolet and the infrared light—in other words, the heat—from entering your home while still allowing the sunlight to pass through.
In northern climates when heat gain is more desirable, a low-e coating is often used in the reverse. The full spectrum of light is allowed into the home as much as possible, but the heat energy it produces is trapped inside. This creates a powerful greenhouse effect that keeps a home extra warm during the coldest months of the year.

Combine an Efficient Window with an Efficient Frame
Installing an energy-efficient window is necessary for saving energy, but it will not do you much good if the window frame isn’t efficient as well. Generally, aluminium windows are the least efficient, even when they are manufactured with a thermal break . These windows simply conduct heat too much to be very efficient.
When searching for an efficient system, Veka uPVC framework combined with low e glass, argon filled is one of most efficient widow systems available.
