What Is Celotex With Plasterboard?
Celotex PL4000 insulated plasterboard is comprised of a board of polyisocyanurate (PIR) insulation bonded to a sheet of standard tapered edge plasterboard, using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential.
The plasterboards are rigid, durable, and lightweight with a low lambda value of 0.022 W/mK, making them the go-to choice for project managers who want to improve thermal conductivity.
Plasterboards are panels that are made from calcium sulfate dihydrate, also known as gypsum. Manufacturers bond a sheet of Celotex insulation board to one side of 12.5mm plasterboard creating an all-in-one product that both insulates and dry lines in one easy application.
Celotex PL4000 Thermal Insulation Board
Celotex PL4000 is a multi-purpose thermal insulation board designed for providing thermal insulation and plasterboard benefits in one robust solution.
Celotex’s standard high-performance insulation board is bonded to a 12.5mm plasterboard that has a tapered edge, which offers the user the ability to install both the insulation and plasterboard in one operation thus reducing installation times.
You can install these boards, in internal walls or pitched roof systems below the rafters, with either dot-and-dab bonding or mechanical fit methods.
All the products in the PL4000 range have a thermal conductivity value of 0.022 W/mK, making them very thermally efficient.
We recommend PL4000 products for internal solid walls, pitched roofs, flat roofs, and timber frame linings. You can install these boards under and between rafters and joists.

Celotex PL400 Insulated Plasterboard Benefits
The biggest benefit of Celotex PL4000 boards is that they quickly and easily insulate and dry line walls in one operation.
Each board combines the low-heat transfer properties of PIR with the structural integrity of plasterboards.
All-in-one boards are perfect for people who do not have time for the traditional lath and plaster process for internal wall lining applications for quicker installation speed.

PL400 Celotex Insulated Plasterboard Thickness
When discussing Celotex insulated plasterboard thicknesses, it is important to understand that the thicknesses shown on our website refer to the overall thickness of the insulation and plasterboard bonded together.
All Celotex insulated plasterboards are made by bonding a Celotex PIR board to a sheet of 12.5mm plasterboard.
For example, the 52.5mm product in this range comprises a 40mm Celotex PIR Insulation board bonded to a 12.5mm Plasterboard sheet. This is why all Celotex insulated plasterboard thicknesses end in 2.5mm.
Like all other insulation products in our online shop, Celotex insulation backed plasterboards come in a range of thicknesses. Our customers can choose Celotex plasterboards that range from 37.5mm to 72.5mm in thickness.
Different thicknesses are suited to different projects. By stocking a range of different thicknesses, we cater to every insulation need.
Frequently Asked Celotex Insulated Plasterboard Questions
Are Celotex Plasterboards Flammable?
Celotex PL4000 thermal insulation boards are a B on the Euroclass scale. This basically means that they contribute to a fire to a very limited extent, their smoke production is very limited and they do not produce flaming droplets.
Are Celotex Plasterboards Vapour-Resistant?
Provided all joints between the product are sealed in accordance with manufacturer instructions, Celotex PL4000 boards can offer significant resistance to water vapour transmission.
How Should I Cut Celotex Insulated Plasterboards?
The two-in-one nature makes these boards far stronger, but more difficult to cut.
Whereas single Celotex insulation boards can be cut with a utility knife, you will need a saw to cut Celotex with plasterboard. You can use an ordinary saw, but we recommend using a saw with fine teeth for a clean, precise cut.
Always take the proper safety precautions when cutting insulation. We recommend cutting insulation in a clear, open space. You should always wear safety goggles and thick gloves.
How Should I Install Celotex Insulated Plasterboards?
Celotex insulated plasterboards are a popular choice because they are extremely easy to install and speed up installation times. The tapered edge plasterboard allows them to fit seamlessly to lots of different joists, frames, and rafters.
You can fit Celotex plasterboards with industry-wide, standard practices. Direct bonding dot and dab (also known as drylining) is one of the most popular ways of installing plasterboards. You can install the plasterboard directly on top of a concrete or blockwork wall application. This process gains its name from the way that the plasterboard adhesive is pasted to the wall in even dots and dabs.
Some people use mechanically fixed installation techniques to secure insulated plasterboards to walls. More often than not, a galvanised mechanical anchor with a concave head can achieve your desired result. There are lots of different types of mechanical fixings that you can choose from.
