U value vinyl doublepane window windows#
The energy efficiency of windows has come a long way in the last couple of decades. With aluminum and wood blending, these windows offered a variety of arrangements possiblities and a wide selection of colors for exterior cladding which reduce maintenance. Their handy opening systems ensure effective ventilation and ease of care. These windows feature structural assembly, an inclined one-piece sill, weatherstripping, and sealed glass to ensure quality, resistance, and superior energy efficiency. But as it is one of the more durable materials, it's generally worth it. Cons: There really aren't a lot of negatives except for cost, as you will have to pay more for fibreglass.Fibreglass is made from silica sand which is readily available and recyclable. They can be made in a variety of colours, as well as with a wood laminate interior for a more traditional look.įibreglass frames are the preferred material of the LEED for Homes rating system due to performance and a more moderate environmental impact than other window frames. This can extend the life of the seals,delaying the inevitable day when the gas escapes. They offer one of the higher insulation values, and they have the best resistance to expansion and contraction due to temperature changes. Pros: Fibreglass frames are lightweight, durable and strong.
It might seem like a deal as you are pricing them out, but due to air leaks you will be paying extra on your heating bills. Until -10 Celsius they perform fine, but as it gets colder than that, the frames contract and the seals detach. Of all the window frame materials you will find, Vinyl performs the worst in cold climates.PVC has specifically been linked to reproductive, brain and immune system disorders. Although the amount from windows is minor, off-gassing of PVC from windows and other products in homes can affect air quality. Exposure to UV (which windows will receive their share of) causes vinyl to break down and release particles into the air. It is extremely energy intensive in production and accounts for 40% of global chlorine gas consumption. So much so that vinyl as a product is banned in many European countries. Cons: The environmental impact during production is significant.Pros: Resistant to moisture, insects, corrosion reasonably good insulation value low maintenance affordable.Vinyl / PVC (polyvinyl chloride) Windows:

The National Building Code of Canada requires aluminum windows to have a thermal barrier of rigid foam, polyurethane or wood to improve their thermal performance aluminum frames are susceptible to water leakage at the joints in the corners.
When we speak of durable and sturdy windows, we are referring to products and construction that are more resistant to pressure and warping due to temperature changes, which ultimately determines the life expectancy of your windows. Air in the cavities between panes expands as it heats up and contracts as it cools, which puts pressure on the seals and frames.
Window frames can be made from a variety of materials offering different levels of performance and insulation values.
