There has been a boom in home extensions in recent times, and using SIP (structurally insulated panel system) modular panels allows us to build strong, high-quality, residential extensions and buildings in a fraction of the time of traditional build.
These durable, high-performance, energy-efficient panels are a very cost-effective building solution and can be used for home extensions, garden rooms, home offices and other stand-alone buildings.
We pre-fabricate SIP panels under factory-controlled conditions, meaning that extension walls will be more airtight and energy-efficient than a traditional build. And the panels are delivered to site ready to be installed.
Has the time come for you to change your conservatory roof? If so then let us help you transform your conservatory into the perfect living space that you can use all year round.
Here at PCL Building Products Limited we manufacture, supply and install our bespoke lightweight tiled conservatory roof. Designed and manufactured in our own factory, with our backed guarantee, and our excellent after-sales support team.
Our lightweight tiled roof provides you with a well-insulated roof which is useable all year round! Our design means that less air can escape and reduces drafts and air leaks considerably therefore the room stays cool in summer and warm in winter and uses up to 60% less energy to keep a stable temperature.
Our Insulated Conservatory Roof is designed to replace an existing glass or polycarbonate roof or can be installed as part of a new installation. We prefabricate the roof in our 40,000sq ft factory in Radcliffe, Greater Manchester.
The installation process is both quick and efficient, creating minimum disruption at your home.
PCL Building Products manufactures precision Structural Insulated Panels (SIPs) for commercial construction — built for architects, estimators, commercial directors, and developers who need predictable performance and a building envelope they can specify with confidence.
Every panel is fabricated to tight dimensional tolerances at our 40,000 sq ft factory in Greater Manchester. The result is consistent structural performance, engineered load paths, and panels that fit as detailed — removing rework and variation from your programme.
Because panels are prefabricated off-site and delivered sequenced for installation, structures are enclosed in a fraction of the time required by traditional methods. Where ground conditions or site access are challenging, our ground screw foundations remove excavation and curing from the critical path — installable in most soil types and producing around 60% less CO2 than concrete.
The airtight envelope delivers very low U-values with minimal thermal bridging, supporting Part L compliance and net-zero-ready specifications without compromise.
