Essential double glazing windows guide

Upgrading a property to new double glazing windows is a sure way to add considerable value when putting a home on the market:  it’s most definitely one of the first things prospective homebuyers look out for.

With great acoustic and thermal insulation performances, it’s little wonder that double glazing is the recommended window solution for most properties out there and here’s how to get it right!

  1. Why should you change windows?

Upgrading your windows to double glazing is one of the most effective ways to insulate a property, alongside floor and attic insulation. Between 10 and 15% of overall energy efficiency is lost on average because of ill fitted or poorly insulated windows and doors, so it’s crucial to evaluate the situation before anything else that would need replacing in the house.

  1. Should you replace all windows at once?

It’s not compulsory, and it depends mostly on your budget. Top priority should be given to the main rooms in the house or the spaces that require heating the most such as kitchen and living room.

  1. Which window frame material should you opt for?

PVC is one of the most popular options at the moment: it’s cheaper, and offers one of the best insulating performances currently on the market. However, you have to consider the overall style of the house too: PVC offers fewer design options than wood or aluminium and could be a definite turnoff for prospective buyers if it doesn’t fit with the rest of the property’s look and feel. If your budget allows it, you could also opt for high end window frames combining several materials to get the best of both worlds, design and efficient insulating properties.

  1. Does double glazing require installing trickle vents?

A property that doesn’t have sufficient ventilation can suffer from condensation problems and moulding issues. New windows implies better insulation and less air coming in and out of the property, so it’s crucial that you check for ventilation solutions, such as trickle vents, in order to improve airflow and prevent the apparition of mould. Trickle vents are one of the easiest ways to deal with these types of problems and they’re also simple to install yourself directly into the window frames, thanks to a bit of drilling action.

  1. Will it involve a lot of work?

It obviously depends on the type of property that’s being renovated or built. Most of the time, it’s a fairly smooth operation: just a case of replacing the frames and putting in new windows without having to interfere with the walls. In the case of house renovations however, walls are sometimes a little worse for wear and will need to be replaced or reinforced. This can take much longer: up to a few weeks or so against 2 hours or half a day for a more straightforward window replacement.
