FAQ

When and why is triple glazing best?
If you’re looking for a thermally efficient home that doesn’t let heat escape, triple glazing is the best choice for you. The 2 outer panes have a Low E glass coating to reflect heat back into your home, while between the panes is krypton, an inert gas that acts as another barrier to retain heat. This technology acts in two ways, keeping heat inside your home and preventing cold from getting in from the outside. Triple glazing is most suited to the north facing elevation of your home where less heat will be coming into your home from the sun. You’re best to mix our A or A+ rated double-glazing with our A++ triple glazed windows to get the ultimate performance. Triple glazing isn’t just better for its heat retention properties, it also acts as a fantastic sound barrier. The extra pane of glass provides extra sound insulation, reducing external noise from roads, railways or airports in your vicinity.

Can I paint UPVC window frames?
You can, but it’s not something we would recommend as there’s a good chance it won’t look very good. If you really want to paint your frames then you can buy UPVC primer that makes it easier for paint to adhere, but once done it’s almost impossible to return to the original unpainted effect. Be aware that by painting or modifying your windows, you will invalidate your guarantee, so give us a call before doing anything too drastic. Walbert Windows does, however, provide a range of window colors to suit all your needs. This includes choosing different colors on the outside and the inside, giving you more control over the design of your home.

Does Walbert Windows do bay windows?

Yes, we do. We offer UPVC bay and bow windows and bay and bow conversions. However, if you’re building a new bay window, then give us a call.


Why is there condensation on the inside of my windows?
Water or frost on windows is condensation. Condensation is formed when warm moist air comes in contact with cooler dry air. An example of this is when a bathroom mirror steams up after a hot shower. Just like that mirror, the inside or outside of your window can sweat or fog because of temperature differentials.

argonWhat is Argon gas used for?

Argon and other inert gasses are used to reduce the loss of heat through an insulating glass unit. Since inert gasses are heavier than air, their molecules do not move as easily. This makes the space between the panes of glass in the window less conductive. Inert gasses between the panes of glass make it more difficult for the warmer inside air to pass through the glass to the colder outside. With lower heat loss, the R-Value is increased.


What is Low-E glass?
This is where low emissivity or low-e glass coatings come into play. Low-e glass has a microscopically thin, transparent coating – it is much thinner than a human hair – that reflects long-wave infrared energy (or heat). Some varieties of low-e glass also reflect significant amounts of short-wave solar infrared energy.
