SIP Panel Extensions
Cambuslang.
SIP panel extensions use structural insulated panels to create strong, energy-efficient building structures. Modular Home Extensions designs and builds SIP panel extensions across Cambuslang — combining architectural flexibility with modern insulation performance and traditional concrete foundations.
What is a SIP
panel extension?
A SIP (Structural Insulated Panel) extension uses factory-manufactured panels that combine structural strength and high-performance insulation in a single component. Each panel consists of a rigid insulation core bonded between two structural facing boards — creating a wall or roof element that is simultaneously load-bearing and thermally efficient.
Because the structure and insulation are integrated, SIP extensions eliminate the thermal bridging found in traditional construction — resulting in a warmer, more energy-efficient space that performs consistently throughout the year.
- Structure and insulation in a single factory-made panel
- Eliminates thermal bridging found in traditional construction
- Manufactured off-site to precise tolerances
- Fast on-site assembly — panels arrive ready to install
- 10-year structural guarantee as standard
How a SIP panel
is constructed.
Each SIP panel is a composite component — three distinct layers that work together to deliver structural performance and thermal efficiency in a single, factory-manufactured unit.
Structural facing board
The outer layer is a structural board — typically oriented strand board (OSB) — that provides the rigidity and load-bearing capacity of the panel. It forms the structural skin of the extension wall or roof element.
High-performance insulation core
The insulation core — expanded polystyrene (EPS) or polyurethane foam — is bonded directly to both facing boards under pressure. This continuous core eliminates the air gaps and thermal bridges that occur in traditional stud-and-insulation construction, dramatically improving thermal performance.
Internal structural board
The inner facing board mirrors the outer layer — providing the structural integrity of the panel from the inside, a continuous surface for internal finishes, and a substrate for service routes routed within the panel.
Architect designed SIP extensions.
Open plan. Modern. Yours.
Our architectural team designs SIP extensions to support the open plan living spaces, large glazing features and modern layouts that contemporary Cambuslang homes demand. Because the structural and thermal elements of the SIP panel are integrated, our architects have more freedom to design expansive, thermally efficient spaces without compromising on performance.
Every project is designed by our in-house team — from the first free consultation through to planning permission, building warrant submission and completion certificate. No third-party architect fees. No handoffs between separate professionals.
- Open plan kitchens, dining and living extensions
- Large glazed panels, bifolds and sliding doors
- Flat and pitched roof configurations
- Planning permission and building warrant managed for you
- One team from first sketch to final sign-off
Traditional foundations
for every SIP build.
All SIP panel extensions we construct are installed on traditional concrete foundations — not ground screw systems — ensuring structural reliability and full building control approval in line with Scottish Building Standards.
Concrete pad or insulated strip foundations provide the stable, compliant base that a permanent residential extension demands. Our groundworks team installs them efficiently, keeping the overall programme on track without cutting corners on what goes beneath the ground.
- Insulated strip foundations or reinforced concrete bases
- Fully compliant with Scottish Building Standards
- Building control approved on every project
- No ground screw or alternative foundation methods
Why choose a SIP
panel extension?
SIP extensions combine structural performance, thermal efficiency and fast installation in a single system — with full architect design and no compromise on layout or appearance.
Superior thermal performance
The continuous insulation core of a SIP panel eliminates thermal bridging — delivering a warmer, more consistent internal environment and lower heating costs compared to traditional stud-and-insulation construction.
Factory precision
Panels are manufactured off-site to exact tolerances in controlled conditions, not cut and fitted on site. The result is consistent quality that doesn't vary with weather, workmanship or site conditions.
Fast installation
SIP panels arrive on site ready to assemble, significantly reducing the on-site construction programme compared to traditional build — meaning less disruption to your household and a faster route to enjoying your new space.
Design flexibility
The SIP system supports open plan layouts, large areas of glazing, vaulted ceilings and modern roof forms. Our architects design around your brief — the system doesn't constrain what's achievable.
Structural reliability
SIP panels are load-bearing by design. The system carries independent structural certification and a 10-year guarantee — providing long-term confidence in the structural performance of your extension.
Pre-approved for building control
The system is pre-approved for Building Regulation compliance, making the building warrant process fast and straightforward. Our team manages the full submission — you don't have to navigate it yourself.

Cambuslang & beyond.
We design and build sip panel extensions across Cambuslang and the surrounding areas. Our local experience means we understand the planning requirements and property styles specific to each neighbourhood.
SIP panel extensions in Cambuslang
— answered.
Do modular extensions require planning permission in Cambuslang?
Planning permission depends on the size and design of the extension. Our in-house architectural team can guide homeowners through planning rules and prepare drawings for building warrant approval.
Are modular extensions installed on traditional foundations?
Yes. All Modular Home Extensions projects are built on reinforced concrete or insulated strip foundations rather than ground screw systems.
Who designs the extension?
Every project is designed by our in-house architectural team. Modular Home Extensions is part of the OBG Group.
