Insulated plasterboards are common building materials that consist of a sheet of standard plasterboard (or gypsum board),and a sheet of insulating material that are infused together into one single sheet.

There are also different types of insulated plasterboards which are standard insulated plasterboards, tapered edge plasterboards and moisture-resistant insulated plasterboards

The reason many homeowners, construction workers and housebuilders use (or suggest using) insulated plasterboards is because the variety of benefits that come in using insulated plasterboards beats other alternatives for other insulating materials within your walls.

Insulated plasterboards can be implemented with nails, screws or even strong adhesives that allow it to be an easier option for some DIY tasks, thus making it a popular choice for homeowners who want to apply these boards within their interior walls.

Cost-effectiveness is also a common reason why insulated plasterboards are frequently used, as the materials within these products are usually cheap to produce.

Other smaller but equally impactful benefits include heat retention, energy efficiency, chemical-free and environmentally friendly materials.

Insulated plasterboards should commonly be at least 30mm thick, and can go up to 100mm in thickness. At UK Flat Roofing, we offer boards between 32.5mm to 92.5mm in thickness, so you have a variety of options to choose from when deciding what thickness of insulated plasterboard should be fitted in your home or construction project.

If you have any questions, feel free to contact us and we’ll advise you as best as we can as experts.

Applying and fitting insulated plasterboard on a ceiling is possible, as long as you acquire the right fixings that fit into the timber ceiling joists of your ceiling. Before fitting insulated plasterboards on your ceiling, ensure you check the exact thickness and layers of your existing ceiling, as it may already have multiple layers applied to it.
