U-value is the measure of the heat gain/loss through the glass of your windows. Essentially a measure of your home’s energy efficiency. The higher the U-value the lesser the thermal performance of the unit will be, costing you more on your energy bills. The lower the U-value the better the insulation you will have, meaning the window has a greater resistance to the heat gain/loss, therefore saving you money on your heating and cooling.
Single Glazed standard window (4mm) U-value: 6.5
Double Glazed Standard Aluminium window U-value: 4.5
Double Glazed uPVC window (4mm-12arg-4mm) U-value: 2.4
glass offers very little resistance, Double glazing reduces heat loss by up to 56%to heat

- It is important to find the right business for you, so that you can feel at ease and rest assured that the substantial investment you are outlaying is in capable hands.
- Meet with several businesses, check what the warranty they offer is not only on the product itself but about the installation and service. A lot of businesses do not follow through on their service calls once windows have been installed.
- Ask around as word of mouth is a powerful source, check reviews on the internet - Google is a very reliable source as the reviews are put up by customers and can not be taken down if businesses don't like them, unlike social media sites such as Facebook etc where the sites are controlled and manipulated by the businesses.
- Make sure you get at least 2 quotes, match apples with apples. If you do not understand the quote fully then ask your supplier to explain it. Make an educated decision not just on the cost, we have had many calls from distressed customers who have ultimately chosen the cheapest quote and then have needed repair work with the business not coming back to fix the issues.
- Does your supplier just supply or do they offer installation as well? Is their installation team qualified to install your windows/doors? What is their qualifications. A lot of manufacturers will not warrant their products if they are not installed by a qualified trades person.
