Lawsons stocks a wide range of insulation materials, including Rockwool insulation, Multi-foil, PIR insulation, and standard mineral roll rolls for loft insulation. Everything you need to bring your new build up to building regulations or increase your home insulation for better thermal efficiency

Effective and Eco-Friendly Insulation

Our range of insulation options means that you can find exactly what you’re looking for, whether it’s the most cost efficient way to reduce heat loss, or an environmentally-friendly solution that reduces your home’s impact on the environment. We even have acoustic insulation for soundproofing, both for individual rooms and to reduce noise pollution from outside.

Choose from insulation specifically designed for warm roof constructions, to improve the thermal performance of exterior walls, or prevent heat loss through the loft. Building regulations are increasingly focusing on the efficiency of buildings as a whole, so new builds will need a variety of insulation installed to prevent heat loss through the windows, roof, and walls.

Our products are non-combustible and moisture resistant to improve home safety and comfort – the individual qualities of each product vary, so please call if you have questions or specific requirements.
The required U-value depends on the type of building, application, and location of the building project. Our insulation will help you meet and exceed insulation requirements on any building project, whether it’s a partial roof renovation, an exercise to add insulation with no building involved, or a new build.

Take a look at our products below, or call or visit your local branch. We hold large amounts of stock but can make special orders for larger projects or more unusual products. We can arrange next day delivery for online or telephone orders if they are agreed early enough – please let us know your requirements and we will do everything we can to meet them.

PIR Insulation

PIR Insulation (Thermal Sheathing)

Our rigid insulation is well suited to use in warm roof constructions. It is robust enough to span the rafters and will resist moisture. Also, its high thermal resistance enables the required U-value to be achieved with a minimum thickness of insulation.
