Windows that perform: A buyers guide

This includes infrared heat from heaters and people, and re-radiated heat from hot surfaces such as pavers outside. Thus, low-e coatings can be used to keep such heat inside in winter, and exclude it in summer. This improves the U-value of the glass and reduces the solar heat gain coefficient . Shading double glazing is even more important than shading single-pane windows, as double glazing will trap solar heat in the home in summer if exposed to the sun. But this doesn’t mean that double glazing shouldn’t be used in warmer climates—it should be used in conjunction with appropriate shading, window coatings or other direct radiant protection.
Windows set down low that are larger than a certain size also must use safety glass. Raising sill heights to 500 mm above floor level can eliminate the requirement for safety glass and save a lot of money, yet  you may still want to consider safety risks for animals and small children. It is also important to remember that a window allowing aluminium doors airflow around it will be a poor insulator, no matter what its materials and construction. Windows that have moving sections should have good seals between the moving frame and the window frame. Most modern commercially-made windows have a reasonable seal, but their effectiveness depends on how well the window is designed and manufactured.

Double-glazed windows are more efficient and utilise more materials, so they’re bound to be more expensive. Depending on where you get your windows from, they can range in price from $200 to $1,500 per square unit. Look for our FSC® certified  wooden window and door products on our website.
In this comprehensive guide, we'll delve deep into understanding the multifaceted benefits of certified windows and explain the rigorous certification process they undergo. Investing in energy-efficient windows is a necessary step for homeowners looking to embrace sustainability. These windows not only enhance the aesthetics of your home but play a significant role in reducing energy costs—especially during the peak of summer. Traditional windows frequently allow the cool air to escape, thus increasing the energy consumption required to maintain a pleasant indoor environment.

They'll examine your windows, walls, and eaves to see if they can spot any significant issues causing leaks into or out of your home. As an investment in a house, efficient windows may cost more initially. Wood frames, offering a classic aesthetic, are excellent insulators but demand more maintenance, including regular treatments to prevent decay. They are favored for their natural beauty but involve a commitment to upkeep. Vinyl frames are a popular choice due to their low maintenance needs and  good insulation properties.
Spread the cost of your new windows and doors with our low rate finance plan from 12.9% APR variable. At Everest, energy efficiency is at the core of what we do and we are committed to offering a range of products with the lowest U-values in the UK. Our triple-glazed windows are our most energy-efficient A++ rated with the lowest market-leading U-values. The calculation for the rating is taken from the positive effect of the G-value minus the U-value heat loss and L-value air leakage.
The tranquility it brought to my home was a clear testament to the power of high-quality window glazing. Double glazing, on the other hand, involves two panes of glass with a space in between – usually filled with an inert gas like argon – which acts as an insulation layer. It’s akin to wearing a double-layered coat in a chilly weather; the air or gas layer traps heat, providing a buffer against the cold.

All the same, proper installation is vital to achieve these benefits. A simple star rating is used—the more stars a product has, the better its energy efficiency level. Homeowners can easily compare different products to see which ones offer the best energy savings. Every single element of our windows and doors has been designed to deal with the harshest weather.
Get the most use from all our timber products by following our simple guide to timber window and door care and maintenance. Upgrading windows at the right time ensures your HVAC system operates efficiently, reduces energy costs, and enhances comfort. One of the most overlooked elements in this equation is home windows. Did you know that up to 30% of your heating energy can be lost through inefficient windows? This forces HVAC systems to work overtime, leading to skyrocketing costs and unnecessary wear and tear.

Energy-efficient windows are key to saving money and making your home more comfortable. These windows have special layers to keep heat out, saving you money all year, especially in cold or hot places. It’s difficult to overstate the importance of windows in home design, not least because they have an impact on both the interior and exterior of a home. And this is one upgrade where it’s important to spring for a well-constructed product.
Energy-efficient windows minimise energy loss, resulting in reduced heating and cooling costs. Buildings account for an estimated 40% of global carbon emissions, with building operations producing 27% of total emissions. The industry can help reduce carbon emissions and promote environmental conservation by incorporating sustainable glass windows. Energy efficiency is an important consideration when shopping for new or replacement windows and doors. There are a number of energy efficient features and benefits to consider when researching windows, including cost, energy savings, comfort, and environmental sustainability.
They had to weigh up material costs, existing supplier relationships and industry practices. Some told us it was cheaper at times to import from Europe or Asia than to buy Australian-made. But our research in Victoria found the main one is cost – double-glazing costs much more than a standard single-glazed window. Houses with double-glazing can add resale value and even improve occupant health. The inherent strength of uPVC reduces the need for frequent maintenance or replacements.

Ever-increasing energy costs make thermal insulation more and more important for building owners. Start by looking for the ENERGY STAR® logo or National Fenestration Rating Council logo on the window  or door you want to buy or install. Window installers and companies will also typically promote products that are NFRC labeled and ENERGY STAR certified so you know up front if they sell and install energy-efficient windows.
Your windows  are made to measure at state-of-the-art factories here in the UK. The Fenestration Self-Assessment Scheme ensures window installers comply with buildings regulations in England & Wales. Everest's policy is one of continued development and in accordance with this, we reserve the right to amend specification of our products as their development dictates. Good U-value building components increase the surface temperature on the inside which is critical in preventing surface mould growth.
