        + Frequently Asked Questions

        Are A-rated windows worth it?

        Do you want to reduce your energy bills? You need an A-Rated window! With the right windows, it can be easy for heat from a fireplace or radiator to escape and make your home colder. But with an A Rating on its side, these problems are gone like magic because of their excellent insulation capabilities.

        What makes an A-rated window?

        What makes an A-rated window? Well, to be honest, it's all about the numbers. Higher the letter the better. The letter rating is calculated using a formula that takes into account the windows’ overall thermal efficiency and air leakage (what percentage of heat from the sun passes through).

        Is all double glazing A-rated?

        No. not all double glazing is A-rated. In the UK, all WER schemes operate on a similar principle: rating the whole window including all of its components, such as frames and gaskets. And under current European regulations, you cannot provide an energy rating for just glass without considering other parts like frame type or air leakage rate from gaps around it.

        How do you stop condensation on the inside of windows?

        You can keep your thermostat at a consistent temperature throughout all rooms, and if there is any room in your home that isn't being used often, make sure you close its door. Another easy trick would be opening those unused doors every day for two hours so they don't get too humid or over-crowded with water vapor from other parts of the house!

        Is condensation on the inside of windows normal?

        Condensation on the inside of windows is just a sign that winter has arrived and we'll soon be warming up with some snow.

        Is water from condensed window fog bad for health?

        Condensation on the inside of your home means there is too much humidity in the room. The actual water droplets on the glass are not a health issue but high humidity in a room can cause health issues.

        What's the difference between A and A+ rated windows?

        A+ windows have a higher energy efficiency rating than A-rated ones. They're also more expensive to order and install, but they save on heating bills in the long run. You can also get A ++ rated windows.

        What U-value are A-rated windows?

        1.4W/m2K is the average for an "A" rating, but some have lower g-values and perform better than others!

        What is the best type of double glazing?

        The best type of double glazing is PVC because it's cheap and efficient. Aluminum frames are not as good, but wooden ones cost more and do the same job. The most popular style for double-glazed windows is casement or sash depending on what you prefer!

        What's the difference between A-rated and C-rated windows?

        A+ graded windows are more energy-efficient than those with lower or no letter grades. The letter rating is calculated using a formula that takes into account how much solar heat passes through, overall thermal efficiency, as well as air leakage of the window product. C Rated windows are a good option for those on a budget.

        What is the life expectancy of double glazing?

        A window that has been fitted to withstand exposure will have a lifespan between 20-25 years, but those in sheltered locations can over 30 years.

        What to look out for when buying windows?

        When purchasing windows, consider what your home needs. Windows provide natural light and outside views while also providing insulation from drafts in the wintertime. The best type of window for any house is one that blocks out wind and UV rays as well as being energy efficient to save on heating costs during cold seasons or cool air conditioning bills during hot summer months!

        What does the U-value mean in Windows?

        The U-value is a measurement of how much heat escapes your home through the windows. The lower his number, the better! A low U value indicates that you will be keeping more money in your pocket due to less energy usage and save on heating costs all year round.

        How much does a window replacement cost?

        It all depends on the material of your new windows and what you're willing to spend. The most common range is anywhere from £150-£1200 depending on how fancy or cheap your preferences are!

        Can I replace windows myself?

        Is there any adjustment on uPVC windows?

        Despite having a more rigid frame, there is no difference in the adjustment process between aluminum and uPVC windows.

        Why won’t my window close all the way?

        Check for paint that's preventing it from slamming shut. Cracks in the window frame can also make your windows too hard to close completely, or worse--prevent them entirely! A bit of dirt could have got into the hinges which over time has rusted the window shut, consult a windows repair specialist.

        Why is my uPVC window not closing properly?

        When a door or window doesn't close correctly, it's usually due to something is worn out on the hinges that interlock with each other and hold up your sash. If you only replace one hinge when this happens, then eventually both will wear down because they won't be working together as well anymore since there are no longer any locks in place for them to catch onto. That’s why you have to replace both hinges.

        How do I stop draughty uPVC windows?

        Draught-proofing your window starts with the locks. There are two types of locking mechanisms you may have: a side lock and a centre channel lock which sits on top of the lower rail. You can simply adjust it using an Allen key, making sure to close tightly against weather stripping at the bottom or outside edge for optimum protection from windy days when cold air wants in! The seal between the window frame and glass is also important - check that there are no gaps before winter hits.

        Why is my uPVC window so drafty?

        Your uPVC windows can't keep the wind out, and this leaves you at risk for colds.

        Double glazing is expensive. Depending on the size, type of window and location of your home, costs can vary between £400 to £800. This depends largely on what you need as well as how long it takes for installers to get the job done with different types of windows needing materials and labor time that are more or less costly than others.

        How do double glazed windows work?

        To create a strong and insulated home, installing double-paned windows is an excellent choice. Double panes of glass are glued together with gas in between the two layers to seal out cold air for the winter and to keep noise from seeping into your living space.

        What are the disadvantages of double glazed windows?

        Double glazing is a good choice for homes in colder climates because it allows less room for heat to escape, but not all properties need double glazing. When deciding whether or not you should invest in double-paned windows, consider your climate and how much money you want to spend upfront. Although double-paned windows are more expensive than single-pane windows, they save you on energy bills over time by keeping the house warmer longer. The added value of an energy-efficient property also makes investing in them worthwhile since these types of houses sell faster and for higher prices than non-energy efficient ones.

        Can you Demist double glazing?

        It might seem like a lot of work but there are ways to Demist your Double-Glazed Windows. If you have condensation on the outside, just wait for warmer temperatures during the day and this should clear up with time.

        Can you repair misted double glazing?

        Repairing a double glazed window is no easy task. A blown pane of glass can't be fixed, and it won't fix the foggy or condensation issues with your panes either. Buying new glass panes for the entire unit is cheaper than repairing misted/blown glazing units on an individual basis.

        How long does double glazing last?

        A double glazed window produced today will last for 30 years on average. If it is fitted in a sheltered location, not subject to any extreme weather and maintained, the lifetime can be increased by an additional 10 years.

        Does double glazing lose its effectiveness?

        Double glazed windows are made up of two sealed sheets of glass with an insulating void between them, but over time the effectiveness can wane. This is because if the seal goes around only one pane, air replaces either a vacuum or inert gas that would normally be in-between. Over time this will cause heat to escape and cold air to enter through the window when it's opened.

        How do you get rid of condensation in double glazing?

        As the cold air from outside enters your home, it creates a difference in temperature that will cause condensation. To reduce this, you should limit the amount of moisture inside your home by introducing less humidity as well as making sure there are no leaks or drafts. As the cold weather sets in, you might notice your house getting a little more stuff.If this is the case, consider these simple steps to help fight off those pesky winter blues: keep your home at constant temperature with less cold surfaces, open up windows or use extractor fans when taking showers and baths to make it easier for moisture to escape from around the house, and don't dry clothes inside as well as not using an extractor fan in your kitchen. These are all small but effective ways of reducing that musty feeling that comes with having damp walls and floors during colder months!

        Can you fit double glazing yourself?

        Imagine how much money you could save if you knew how to install double-glazing. But, the truth is that it can be a disaster if done incorrectly and it takes a lot of skill to do well. Don't try this at home! It is possible to double-glaze yourself and taking this course of action will enable you to save some money while looking out for your own best interests. However, unless you are proficient, highly competent, and have all the right tools, it could be a disastrous and expensive decision to install DIY double glazing. The installation of new windows is something that most people are hesitant to do themselves, mostly because they don't want to risk damaging their property and have to pay for the cost of a professional. It's important that you get the proper training before going ahead with your own window installation, and if you don't then it might end up costing you more money in the long run. If you're not an expert on installing windows then it could be best to hire a contractor rather than risking doing it yourself and potentially having legal issues when selling your home.

        How do double glazed windows reduce heat?

        Double-pane windows are for those who wish to save money and keep their home cozy. Double-panes of glass have a special gas in between the two panes that keeps it insulated from heat loss, keeping your house warm during winter months and cool during summer. Aside from this, they also provide protection against sound waves which can be an issue with single pane glass. Double pane windows are created with a special gas inside the two panes which provides insulation against heat loss during winter months or hot days in the summertime. They also provide soundproofing because of how thick they are, preventing noise from penetrating through them into other rooms of your house.

        Can you just replace the glass with double glazing?

        Single glazing has a serious problem, which is that it's too thin. With the depth of double glazing being much greater than single glazing pane, it is often impossible to swap out single glazing for a double-glazed window in the same frame. If you currently have single-glazed windows, there are two possibilities: either the whole window will be removed and replaced with a new high-performance double-glazed window (with new frame) or just one side of the top portion of your old glass will be swapped out to make room for another piece of thicker glass on that side.

        How does double glazing help keep a house warm?

        Double-glazing is a window consisting of two panes of glass separated by argon gas. The layer of argon gas has 67% thermal conductivity, which means it's not very good at keeping heat inside your home and can even make the air in your house worse. This also helps improve energy efficiency because the warm air can't escape easily.

        Can you replace just the glass in a double glazing window?

        Some windows can be replaced due to broken glass and the old glass should match the size and depth as close as possible. The replacement window pane needs to fit snug in the frame for it to work. Windows with blown/misted glass lose their energy efficiency performance, which is why it's important to get them replaced immediately. Reviews with
