With the amount of choice you are given when it comes to ordering new windows, you’ll likely have many questions in order to make the best decision for your home. We can help!
Can you explain the difference between flush and casement windows?

Yes! A casement is the part of the window that moves, opens and closes. On a standard window, also known as lipped, casements sit above the window frame.

However, many homeowners want a casement that sits completely level with the window frame, which is why the flush casement window is so popular. The design is flush and neat. Come down to our showroom to view the difference for yourself.

Oak Envisage Flush Windows
Should I choose Double Glazed or Triple Glazed Windows?

First of all, you’ll need to understand the difference between the two. Double glazed windows have two panes of glass within the unit, whereas triple glazed windows have three. We encourage you to speak to the team at Eden windows for advice on which would work best for you as there are advantages and disadvantages to both.

Typically, triple glazed windows work better at keeping heat within the home and minimising cold spots. They can also better soundproof your home.

Each one of our knowledgeable advisors are more than happy to explain the answers to your questions. Read the answers to a few of our most common questions below.

What is the difference between PVC Windows, PVCu Windows & UPVC Windows?

This is a trick question – there is no difference! However, the correct, technical term is PVC-U.

The official name was once UPVC, but the UK changed the name in the late 1980s to fall in line with European countries. In most European languages, they place the noun (PVC) before the adjective (U).

PVC refers to Poly Vinyl Chloride and the U refers to Unplasticised. You are likely to be familiar with the term PVC as PVC is modified to be used in many common products, such as fake leather, bags and shoes.

Pure PVC-U would not work for replacement windows and doors, so we add a tiny amount of additives, which provides weather and UV resistance and increases longevity of the product.

Which colours are Eden’s windows and doors available in?

They certainly do! There was a time that all windows had to be white, but thankfully this is not the case now. Our replacement windows are available in a massive range of shades.

If you still love classic white or cream, this is no problem. But many homeowners are looking for modern and on-trend colours, from Matt Black to Olive Grey.

We can also show you our collection of wood grains, from the bright, oak effect colours to the rich and dark colours.

If you can’t decide between two colours, why not have one on the inside and one on the outside? Most of our windows are available in different colour combinations – speak to us for more information.

I hear a lot about energy rated windows! What does 'A' rated windows mean?

Window Energy Ratings (WERs) use an easy to understand traffic light style to help homeowners figure out how energy efficient their new windows will be. This is similar to the energy ratings you find on white goods in your home such as fridges, freezers, washing machines etc – using a scale of A+ – G.

An A+ energy rating is recognised by the British Fenestration Ratings Council (BFRC) as being above normal recommended energy efficiency standards.

We encourage you to choose windows that carry an A or A+ rating for an energy-efficient home.

New and replacement windows require a minimum Window Energy Rating of C. Ask our friendly team for more information on this important part of shopping for new windows.

What does U-Value mean?

A U-Value is important because it communicates how well your windows will be at keeping internal heat inside the home. If heat easily escapes, you will need to keep turning up or heating or risk getting too cold! U-Values are measured in Watts per square metre or W/m2 K. The lower the number, the better the window performs at retaining heat.

New and replacement windows require a minimum U Value of 1.6 W/m2 K. Speak to an Eden advisor for further guidance on this.

What is Secured by Design?

Secured by Design refers to the security initiative that was developed by the police, with the mission of increasing the security of buildings and their immediate surroundings, in order to create safe spaces to live.

Commonly abbreviated to SBD, their product-based accreditation scheme – referred to as the Police Preferred Specification – offers a recognised standard for all security products with the goal of reducing crime. The scheme includes products such as domestic windows and doors, and the components within them such as locks and hinges.

Conservatory Outlet (part of the Conservatory Outlet Group), our sister manufacturing company, is a registered member of Secured by Design. Therefore, numerous products of ours have been tested to meet the demands of the standard. An Eden advisor will be more than happy to explain more.

Is Eden a member of FENSA?

Yes, we are very proud that Eden is a member of FENSA (Fenestration Self-Assessment Scheme). The scheme was started by the Glass and Glazing Federation (GGF) and other industry bodies with Government backing, to help homeowners comply with England and Wales’ Building Regulations.

If you are having replacement windows and doors installed, then it is necessary they meet current thermal performance standards and you must ensure you receive a certificate of compliance from FENSA or from Local Authority Building Control.

As a FENSA member, we are able to self certify compliance under Building Regulations.

What can I expect to pay to replace my windows and doors?

We will need to find out more about your requirements before giving you an accurate quote.

Our windows and doors are tailor-made to your measurements so we need to spend time with you first. There are many options when it comes to style and they do vary in price.

The first step is requesting a free design consultation, so we can find out exactly what you’re looking for and if you have a budget in mind. If you don’t know yet, we can help guide you!

Fill in your details onto one of our contact forms and we’ll be in touch to arrange a time and date that works for you ‘Appointment Booking Form‘.

How long will an appointment with your designer take?

A minimum initial appointment time of 1 hour is recommended. An Eden designer can take you through your options, as well as listening to what you had in mind.

How long will it take to install my new windows and doors?

This is a difficult question to answer because each job varies so much. It depends on how complex the job is and how many windows and doors we are installing. Often, a full house of windows will take around 3-4 days. We can give you a more accurate idea once speaking to you.
