Is triple-glazing worth the extra cost?

Your guide to the benefits of installing triple glazing

Promotional Feature By Jennifer Turner |

Whether it’s as part of a new build or retrofitting your existing home, glazing is a key consideration. With everything from energy use to acoustic performance on the line, it’s worth taking the time to find out if the extra spend required for triple glazing is worth it for your project.

Is triple glazing worth it?

Energy use is a very important factor in modern homes, with an increased emphasis on conserving energy, making homes more heat efficient and cutting energy bills. When designing a new home, or making improvements to your current one, you need to take a holistic approach to heat loss, and this means not just the walls and roof, but also the doors and windows. Triple glazing can make a great contribution to your home’s ecological profile.

Is triple glazing better than double glazing?

More isn’t always better, but in the case of professionally installed triple glazing it is. The extra layer of glass – and the inert gas between it and other pane – reduces the U value (thermal transmission, where the lower the rating the better) of the window significantly. If you’re aiming for a Passivhaus low energy building, then quality triple glazing can make a big difference.

Is it worth the money?

An upgrade to triple glazing is an investment that may take the medium term to recoup in terms of energy bill savings,  but it will make an immediate impact on heat waste, which is important to many self-builders and architects.

It’s also worth considering the other key benefits of triple glazing – the increased acoustic performance shutting out unwanted noise from outside, and increased security.

Is it easy to install?

Triple glazing is heavier than double glazing, so if you’re building a new home, you or your architect should account for this in your plans. If you’re retrofitting into an existing building, then you’ll need to consider thermal bridging to ensure there are no gaps in your insulation, creating weak points.

This is why it’s vital to use an experienced and professional installer so that your window performs to its maximum ability. Green Building Store supplies and fits timber and alu-clad windows and doors with knowhow in both new and older buildings.
