Fibreglass insulation is found in most properties across the UK and is in fact the most commonly used product in our homes today. At one point in time, many would argue that this was the best choice or method available, hence why you will find it in millions of loft spaces all around the world. However, that perception and idea is changing. Fibreglass is becoming outdated and less effective in comparison with other alternatives and methods such as spraying foam, which is becoming more and more widespread.

Here are a few reasons why.

Thermal Qualities
The barrier that spray foam creates stops air escaping from your home and stops cold air from entering in. Whereas fibreglass acts more like a woolly-jumper, allowing air to pass through its delicate fibres. This air leakage can cause you to see a rise in your energy costs. So spray foam definitely wins the first round of spray foam insulation vs traditional insulation.

This expansion means it can fill every nook and cranny with ease, allowing you to effectively insulate even the most awkward areas and property shapes. Whereas on the other hand, it’s hard to fit fibreglass pieces perfectly into place to achieve a similar all-encompassing effect.
