What makes windows more energy efficient?

Creating a home that stays warm all year round and benefits from reduced energy costs, if you can believe it, can be as simple as installing energy efficient windows. We at Turkington know a little bit about this, having operated as a respected double glazing installer for well over 70 years across Dublin and Northern Ireland. That’s why, for homeowners wondering how to improve their home’s energy efficiency, we’re here to put any confusion to bed and highlight what can make your windows more energy efficient than ever before.

Three material choices for energy efficient windows

The first thing to know about energy efficient windows is that there are three unique frame materials to pick from. Too often do people assume that material is a factor that purely affects a property’s aesthetic, when the truth is that it also plays into how successful your home is at combating such issues as draughts, condensation, and heat loss. Which window material is best for energy efficiency? Here’s a brief summary about what PVC, Aluminium, and Lumi all offer.

PVC is the most popular window material due to its relative affordability. However, modern uPVC windows are more energy efficient than ever, using such technologies as multi-chambered frames, low-e glass coating, and triple glazing to prevent heat loss. Aluminium windows, by comparison, offer all this while retaining a look that is sleek and modern due to minimalist frames. However, it’s frameless Lumi windows that are considered to be the most energy efficient option on the market, as their uninterrupted profiles offer U values as low as 0.7 – always remaining stylish and energy saving for the eco-conscious homeowner.

Small thermal window techniques help make a big difference

With your energy efficient material selected, making your windows as insulating as possible comes down to other small optional choices available. For instance, opting for argon-filled triple glazing over conventional double glazing provides an extra layer of defence against any escaping heat. While you’re at it, why not upgrade either your new or existing windows’ glazing to low-emissivity glass? Such a technique has been statistically proven to prevent heat loss by up to 75% (depending on the brand used). This handful of subtle glazing techniques help make all the difference.
