Slab insulation is among the most effective ways 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!

Which Brand is Best?

We supply insulation batts from a variety of manufacturers. These include Knauf, Superglass and Rockwool. Each are widely recognised for their commitment to innovation and quality products, used in thousands of properties across the country. We recommend choosing your insulation based upon the thermal efficiency, acoustic performance and material. This is as each of our insulation slabs offer unique features and capabilities.

Which Insulation Slabs Are Best Suited to 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 an insulation manufacturer.

They will be able to recommend the appropriate 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 either on our website or by contacting our experienced team.

How to Cut Slab Insulation?

It’s always best to cut insulation slabs using a serrated edge, such as with a fine tooth saw or even a bread knife. It may be easier for you to mark out where you need to cut using a straight edge and a felt tip pen. Simply carefully slice along this line until your slab is at the desired size. Avoid cutting insulation to be too tight a fit, as a very slightly loose fit often works best, particularly for acoustic insulation. Please remember to wear PPE when working with mineral wool, as it cause severe irritation.

Slab insulation is one of the most common types of insulation used in Britain today. This is thanks to its easy installation and unrivalled thermal efficiency. Insulation slabs, also known as insulation batts, are truly versatile, and can be installed into walls, floors and roofs.

Installing insulation slabs into your home is an excellent way to drastically reduce heat loss and shrink annual energy bills. Reducing the U-value of your property will also help you to meet national regulations without having to invest in a variety of insulation types.

Slab insulation is most commonly made from glass wool, mineral wool or sheep’s wool. Instead of being moulded into rolls, the material is formed into rigid slabs which makes them easier to install. They fit neatly between joists and battens in loft spaces and ceilings, as well as fitting snugly into walls.

Benefits of Slab Insulation

Superb Thermal and Acoustic Insulation

Insulation slabs utilise modern materials to provide highly effective thermal and acoustic insulation. The most common material in slab insulation is mineral wool, which is excellent at reducing heat loss.

We work with top brands such as Rockwool, Knauf and Superglass, whose innovative products offer maximum protection from thermal leakage and sound transmission. For example, the Rockwool Flexi features a patented flexible edge to ensure a snug fit for years to come. This brings an end to cold spots or poor acoustics.

Ideal for Insulating Walls, Floors and Roofs

Insulation batt’s rigidity means it can be used almost anywhere in your home. Whether that’s insulating internal or external walls, flooring or pitched roofs. Due to the slabs’ ideal sizing, you needn’t worry about having to cut them down to size on-site.

If you do need to cut an insulation slab, however, ensure that you have a fine tooth saw as well as appropriate personal protection. This makes installing the slabs hassle-free for both tradesmen and DIYers.

Designed to Prevent the Spread of Fire

Preventing the spread of fire through your property is one of the foremost concerns for manufacturers. That’s why they’re committed to using non-combustible materials in their slab insulation.

This has resulted in many slabs in our range being accredited as Euroclass A1. This highly regarded accreditation should provide you with the peace of mind that your property is safe from fire. Insulation batts effectively combat the spread of fire, which gives more time to escape and reduces damage to your property.
