Buying Guide

Not all windows and doors are created equal!

That’s why it is important to understand the various features of windows and doors and how to select the right ones for your home. In this buying guide, you will find fundamental information about our windows and doors.

The importance of u values for energy efficiency

Technology advancements mean that windows and doors manufactured today are vastly different to those of ten years ago. To compare energy efficiency and understand how it is measured today, u values are used to measure heat loss.

Traditional windows and doors were typically awarded a u value of between 2.5 and 3.5 W/m2 K. Today, the Astral Windows and Doors range boasts average a u value of 0.8 W/m2 K. This represents a 300% increase on energy efficiency on traditional windows and doors.

The lower the u value, the better the window and door is at minimising heat loss. The more insulated a product is, the better u value it will have. Yet the window or door is not the only factor required to achieve optimum energy efficiency; the quality of installation can also affect heat loss, where gaps can create draughts and allow heat to escape.

When selecting windows and doors for your property, it is important to consider the u value of the product and ensure your installer guarantees only the highest quality installation to achieve optimum energy efficiency.

Home security

Window and door technology plays a key role in crime prevention. On average, intruders will take just 90 seconds to break into a home. If they have not been able to gain access within four and a half minutes, statistics show they will move on due to the increased risk of getting caught.

Astral Windows and Doors is proud to supply and fit quality windows and doors that have Secured by Design accreditation by the Association of Chief Police Officers. The scheme recognises home improvement products that meet the principles of “designing out crime”. That means you can have peace-of-mind that your front door features the latest intruder barriers.

Energy efficiency and security are incredibly important, but so is aesthetic appeal. We understand your home is a reflection of your personal style and stock an expansive range of windows and doors alongside endless colour options and non-corrosion door furniture. Furthermore, our windows and doors are weather resistant, ensuring their appeal lasts for many years and stands up to the Irish weather.
