Insulated plasterboard suits solid wall buildings where adding external insulation is not possible. This often occurs due to planning regulations or the high expense of external work. By bonding insulated plasterboard directly to the interior walls, we deliver an effective insulation upgrade where alterations to the outer side of the building aren’t feasible. This approach keeps everything contained within the property’s interior.
For builders aiming to improve efficiency, insulated plasterboard provides a practical option that combines insulation with plastering in a single step. Our experience guarantees precise fitting and finishing, which reduces labor time and minimizes the need for several trades on site. This method maintains project schedules and delivers a consistent, high-quality finish that is ready for decoration.
Homeowners in Streatham seeking to enhance energy efficiency without extensive renovations will find insulated plasterboard a practical choice. It adds insulation and a smooth finish in one go; this minimizes disruption inside the home. We manage the entire procedure, starting from the measurement to the final finish, ensuring an easy, reliable upgrade for solid wall properties.


Standard drywall plugs fail here. When fitting insulated plasterboard in Streatham homes, we always remind owners that heavy mirrors, boilers or floating book shelves require deep core fixings running straight into the masonry behind. Light picture frames sit securely in the gypsum face. For massive kitchen cupboards, timber battens must be marked early.
Cables need breathing room. Adding thermal panels brings the wall face further out into the room, meaning your existing back boxes cannot stay flush without extension collars or rewiring by an electrician. We check every back box before fixing panels so switches sit square against the fresh skim rather than recessed dangerously behind thick foam.
Insulated plasterboard offers thermal protection directly to solid walls without compromising room dimensions, unlike bulky external systems. This keeps interiors practical while enhancing energy efficiency.
Installing insulated plasterboard avoids tasks on the building’s exterior, perfect when planning rules or site conditions block external insulation. It’s a straightforward solution that respects the property’s appearance.
Combining insulation and plasterboard into one product means fewer steps required on site. We fit insulated plasterboard accurately, cutting down labor time and reducing disruption during renovations.
After we install insulated plasterboard, we finish joints and edges to create a uniformly paint-ready surface. This process eliminates the need for further plastering, speeding up the overall project.
Proper installation of insulated plasterboard guarantees continuous insulation without gaps or thermal bridges. With over 20 years of experience, we ensure the system performs effectively, providing enduring results.
The use of insulated plasterboard cuts the necessity for separate insulation and plastering trades, lowering labor expenses. This pragmatic approach aligns perfectly with projects where budget and timelines are critical without sacrificing quality.
Before we install insulated plasterboard, our team conducts precise measurements and inspects the solid walls to ensure a proper fit. This step is crucial for preventing gaps that could impact insulation efficiency. Our extensive experience with insulated plasterboard enables us to adapt the installation to each wall’s specific circumstances, addressing any irregularities on site.
We affix insulated plasterboard directly onto existing solid walls, maintaining insulation continuity without altering the property’s exterior. Precise fitting and sealing of joints prevent thermal bridging, ensuring the insulation operates as designed. Our crew handles the boards with care and finishes the surface smoothly, preparing it for decoration or additional treatment.

We examine the solid walls to ascertain suitability for insulated plasterboard, confirming it fulfills insulation requirements without impacting the building’s exterior.
Our team takes precise measurements to customize the insulated plasterboard panels for an ideal fit, preventing gaps and thermal bridging.
We prepare the existing walls by cleaning and priming as necessary to ensure a solid bond for the insulated plasterboard.
We securely fix the insulated plasterboard directly onto the walls, maintaining insulation continuity and structural integrity throughout the process.
Lastly, we seal all joints and edges, apply plaster for a smooth surface, and ensure the insulated plasterboard installation is ready for decorating or further work.
Never seal wet masonry. If cold autumn rain penetrates an unpointed external wall, fixing insulated plasterboard in Streatham over that damp spot risks trapping moisture deep inside your brickwork. We check damp levels first. Warm interior air meeting cold masonry behind badly sealed thermal sheets causes unseen rot unless the vapour control layer remains unbroken.
Heating pipes need altering. Bringing a room lining forward reduces clearance behind radiators, which often demands plumbing adjustments to shift copper tails away from the cold exterior boundary. The plumber must drain the central heating loops before boarding starts around window bays. Cold snaps reveal quickly whether pipe runs were protected from sub-zero drafts.


Narrow frames cause trouble. Thick insulated plasterboard in Streatham rooms can swallow deep window frames completely, blocking hinges and preventing casements from opening properly. Thin reveal panels prevent this cold bridging around draughty wooden sash bays.
Old timber often splits. Removing original skirting boards before lining solid walls often pulls brittle lime plaster right off the base brickwork. We inspect the floor perimeter to see whether base timbers can be salvaged or if fresh mouldings must be fitted afterwards.
Original cornices demand care. Tucking thick thermal boards against decorative ceiling coving requires delicate scribing so period plaster profiles do not get buried under new sheets. Sometimes halting insulation beneath the frieze preserves historical details.
With over 20 years of practical experience, we approach every insulated plasterboard project capably. We grasp the complexities involved in fitting insulated plasterboard to solid walls, guaranteeing that the insulation layer is both continuous and effective. Our methods avoid common issues such as thermal bridging, yielding strong results that prevail over time. With insulated plasterboard, we streamline the installation process to meet your requirements without compromising wall integrity or external aesthetics.
We manage the installation of insulated plasterboard from beginning to end, starting with meticulous measurements to guarantee a perfect fit. Our team bonds the panels straight to the existing walls, avoiding extra steps and materials. This strategy saves time on site and alleviates disturbances, especially when external insulation is impractical. We complete the job with clean, smooth surfaces that are ready for decoration, merging insulation and plastering into one dependable service.

Craftsmanship you can see
Every plastering project we complete leaves walls smooth, durable, and ready for whatever comes next.
It depends on whether you fix directly into shared masonry. If adhesive or mechanical anchors penetrate deeply into a shared party partition, notifying neighbours prevents disputes, particularly in terraced Streatham properties where sound travels between old adjoining brick structures.
Ask how they handle window reveals and vapour barriers. Competent trades explain thermal bridging immediately and describe how they seal joints, rather than merely treating the panels like ordinary sheets of basic plasterboard without regard for condensation.
Move furniture into the room centre and pull up edge carpet strips. Plasterers need clear access along all exterior walls, and removing curtains, blinds, and radiator covers beforehand prevents accidental damage from adhesive splashes during work.
Supply clear photos showing window bays, radiator locations, and wall surfaces. Note any history of penetrating damp or crumbling masonry, because fixing substrate problems changes the preparation work needed before drylining can safely proceed.
