The light, wafting smoke of the incense will move with a very low air current, which you might not be able to detect yourself. Having secured a superb reputation for delivering market leading products for over 50 years, you can trust Starglaze to take you one step closer to your perfect home. Starglaze Home Improvements are a family run business, manufacturing home improvement products in Lincoln since 1974. Glass that lets less heat pass through it, has a lower u-value than ones which let more heat out. Furthermore, the uPVC profile that we use to make windows contains many chambers. We supply UK wide and can also provide an installation service to most areas of the UK.

The BFRC (British Fenestration Rating Council) gives windows a thermal efficiency rating from A++ to G, with A++ awarded to windows with extremely high levels of efficiency. For any window to be considered ‘energy saving’, it must be rated a C at the very least. The aim of an energy efficient window is to reduce the need to consume energy in a home through heating or cooling a room. Replacement windows will be more airtight than your original frames, so condensation may build up in your house due to the reduced ventilation. If your house does not have much background ventilation, look for replacement windows with trickle vents incorporated into the frame to let in a controlled amount of ventilation. If you can’t install double glazing – for example, if you live in a conservation area, period property, or listed building – you can install secondary glazing, use heavy curtains, or preferably both.

The various materials available all have different qualities and could help to increase the efficiency of your home. To meet ‘Energy Saving Recommendation’ certification, the windows must be C-rated at the very least. It’s not just the type of glazing in a window that will affect its energy efficiency. These figures from the Energy Saving Trust show how much you could save each year if you replace single-glazed windows with double-glazed ones. More efficient windows generally have pane spacers containing little or no metal.

If your home has its original single-glazed timber windows or uPVC windows that are more than 20 years old, it might be time to replace them to cut down your energy bills. There are a number of straightforward DIY options when it comes to energy efficiency, like using draught excluders and insulating loft and underfloor spaces. The BSI Energy Rating system is the UK’s national system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method to show compliance. BSI window energy rating uses a traffic-light style A-E ratings guide similar to that used on white goods (such as fridges, freezers, washing machines etc). As well as taking U values into consideration, the BSI energy ratings also take into account the nominal solar heat gain provided by windows.

The GGF monitors the performance of members, ensuring the standard of products passive house windows and installation remains high. The window rating is usually lower than the glass rating and U values actually increase with the size of the window. The U-value is rated on a scale from 0.01 W/m2K being ultra-low to 4.8 W/m2K which is a high rating for single glazing. Shortwaves can pass through glass but the longwaves can't, so the thermal energy of the infrared radiation becomes trapped and the room begins to overheat.

This includes cleaning, checking for damage andensuring that all windows in your home close properly. Over time, componentssuch as frames and seals can deteriorate, leading to gaps and drafts. At Majestic Designs our range of windows are rated A+14 on the WER scale. That means our windows not only succeed in insulating homes and retaining heat effectively, but are certified as some of the most energy efficient windows available on the market today.
