What Makes a Good Window?

Technology is seeing advances every day and we’re not just talking about mobiles and computers – we’re talking about windows.

 With all the science, research and products around these days, it can be overwhelming to choose what windows are best for you. When making an investment that big, you want to ensure that you are getting the best deal but end up with a final product that is best for you and your needs.

At Crystal Clear we have compiled a simple list of what we think should be on your check list to consider before going out and making the purchase.

The Frame

Most great things need to be built with a strong foundation and in this case, the foundation is the frame. The frame acts as the structural backbone of the window itself so the need for it to be strong and rigid is essential. If the frame is of poor quality, it doesn’t matter how good the window is – the lifespan will inevitably be shorter and cost more in the long run.

A little bit of flexibility is good as long as the joints are strong.

And obviously, the frame is make or break for the appearance of the window which is inevitably going to come into play whilst choosing.

Air Infiltration

Air infiltration, also known as air leakage, is the unintentional introduction of outside air into a building. When it’s the other way round, it’s called extraction. Multiple things can cause this; cracks, chips, wind damage in the corners etc.

Air infiltration ratings are very low on vinyl windows because the corners are welded rather than screwed meaning the gap is very tight. On any other type of window, you’ll want to look at the weather stripping which can be found around the edge of the glass. This is usually made out of felt, fiberglass or in cranked open windows it can be rubber.

Much like windows can be double or triple glazed, windows can have multiple weather strips making it less likely to suffer from air infiltration.

A good window will have no air infiltration or extraction. Our windows also come with brush seals around the openings for exceptional draught proofing.

The Glass

This is where the cheap option is NEVER the best option. Regardless if everything else is in place, if the glass is poor then your window will not be effective.

Low-E Glass

A Low-E glass has a film applied to it to block harsh UV rays and block any heat coming from the outside.

There are varying degrees of Low-E glass but we recommend all types. You can speak to a member of our team to find out what level will be best and most cost effective for you.

Double or Triple Glazing

Another thing that will affect the quality of your windows is the thickness and the spacing between the panes of glass. We discussed the difference between double glazing, triple glazing and secondary glazing in our recent blog post on cancelling out the noise with double glazing.

Window Energy Rating

Having an energy efficient window doesn’t only reduce condensation making the window of less maintained, but it also retains heat within the house better meaning lower energy bills and a reduced carbon footprint.

Most windows will now come with a colourful sticker on with a rating from A-G which will tell you how energy efficient your window is. Considering up to 25% of the heat within most homes escape through the window, it’s not surprising that most people are now opting for A rated windows.

The Number of Panes

The number of panes will be determined by your needs, location and budget. If noise pollution or temperature is an issue around where you live then double glazing is a must; potentially even triple glazing.

A window of the highest quality will have three panes of glass with varying thickness and gaps between the panes. Triple glazing has many advantages such as being energy efficient, safer and more durable. However, others do find that double glazing does the job just as well.

Your window expert will be able to advise you on what is best on your budget and location.

Why Composite Doors Out Perform Traditional Timber Doors

Composite Wooden Door on House Exterior Choosing the right material for your front door can often be a tricky decision; especially when you’re a little inexperienced about what is on offer.

A traditional timber finish is a much sought after appearance for many residential properties. However, they are often expensive and generally require more maintenance. uPVC is certainly the cheaper option but can be seen as less secure and not quite as visually appealing.

Composite doors however, offer the best of both worlds and are, in our eyes, the clear winner. Let us explain to you in a bit more detail:
