🛠 How We Install Internal Wall Insulation
🛠 How We Install Internal Wall Insulation
At J. Barber Plastering, we offer two high-quality methods of applying internal wall insulation to solid walls, both designed to enhance energy efficiency, comfort, and finish quality.
➤ Method 1: Insulated Plasterboard Direct Fix
➤ Method 1: Insulated Plasterboard Direct Fix
We start by applying high-performance insulated plasterboards directly onto your internal walls using a strong, durable adhesive. Once in place, each board is mechanically fixed with screws or proprietary fixings to ensure maximum security and long-term stability.
This method offers:
A fast, clean installation with minimal disruption
An energy-efficient, ready-to-plaster surface
A great solution for retrofit insulation in homes across Chesterfield, Matlock, Bakewell, Rotherham, and surrounding areas

➤ Method 2: Stud Wall with Cavity Insulation
➤ Method 2: Stud Wall with Cavity Insulation
For more complex walls or to improve breathability and moisture control, we may build a stud framework using either timber or metal. This creates a ventilated cavity between the insulation and the solid wall, helping to prevent condensation and damp issues.
We then:
Fill the cavity with insulation
Securely fix plasterboard to the studwork
Prepare the surface for plastering and final decoration
This method is ideal for properties prone to moisture or for clients looking for superior thermal and acoustic performance.
