It can be a minefield picking out the differences between construction products, especially with so many competing claims about what is the ‘best’ solution.
Insulation solutions are the perfect example – all offer a low thermal conductivity, but exactly how low do you need to go? Does it automatically follow that the insulation with the lowest thermal conductivity is the ‘best’ solution?
It all depends what you are specifying a solution for. Here at The Build Up, we try to take a broader view of building construction and performance, aiming for the best quality and the best long-term outcomes. This month we’re getting into the correct calculation of ground floor U-values, and looking at a comparison between XPS and PIR insulation. Read on to find out more.
What do architects need to know about calculating U-values for ground floors?
Last month we looked at the fundamentals of U-value calculations and what you needed to know about the combined method. This month, we’ve written about the specifics of ground floor U-values. Heat loss through a ground floor is different to any other construction element, and we look at the detail of what information helps us to provide you with the most accurate calculation.

Raw material shortages, international shipping delays and product price increases are all putting a squeeze on the construction industry at the moment. It’s more common than ever for contractors to seek approval for alternative solutions that are more readily available or more cost effective.
If you’re a regular specifier of PIR insulation and you’re finding that price rises and product shortages are hampering your projects, you might be interested in our new article that sets out why XPS could be your new go-to floor insulation of choice.

Getting More From Polyfoam XPS
So far in this issue of The Build Up we’ve looked at U-values for ground floors, and comparisons between XPS and PIR insulation.
We’re developing a range of resources about why XPS insulation is the ideal ground floor insulation solution. You can view our accredited online CPD session, and in the next few weeks we’ll publish a new white paper looking in detail at ground floor performance requirements and insulation options.
We are also developing a white paper and other resources looking at the use of XPS insulation in the base of masonry cavity walls, below DPC level.
While we work on these new in-depth publications, you can download our current white paper on inverted flat roof specification, including the assessment and certification of insulation systems
