Common Questions

Slab insulation is amongst the most effective way to increase the thermal efficiency of your property whilst minimising sound transmission. This is due to them being ideal for virtually any use, whether you're insulating your loft or floors. There are, however, a few common questions our customers ask before buying this insulation. Below are answers to each of these! 

What is the U-value of Slab Insulation? 

This can vary for each insulation slab, as different materials and build-ups achieve varying U-values. Where possible, we display the U-value of each insulation slab on the product page. However, you can not achieve the U-value required in your region through the insulation alone. This is as the U-value you achieve is determined by all the materials used on your roof, walls or floor. You can learn more about U-values by clicking here.   

Which Brand is Best? 

We supply slab insulation from various manufacturers. These include Knauf, Superglass and Rockwool. Each are widely recognised for their innovative materials and their products are used on thousands of properties across the country. We recommend choosing your insulation based upon the thermal efficiency, accoustic performance and material. This is as each of our insulation slabs offer unique features and capabilities. 

Which Insulation Slabs Are Best Suited for My Project? 

The insulation you require is determined by local building regulations and the other materials used in your property. We therefore recommend consulting a qualified tradesman or contacting a insulation manufacturer. They will be able to recommend the appropriate build-up of materials based upon the required U-value. They will then confirm the exact insulation slab you require, which you will be able to easily find on our website or by contacting our team.
