Building & Extension Services — Expert Integration with Glazing

The Fenestration Network, we provide a comprehensive, end-to-end service that brings every stage of your project together under one expert team. From foundations and brickwork to glazing and finishing, we seamlessly coordinate every trade to guarantee precision, performance, and a smooth experience for you.

We don’t just install glazing — we build around it.

Our integrated approach means the structural and glazing elements are designed and executed to complement one another from the start, delivering:

• Perfect junctions between structure and glass (no leaks, no cold bridges)
• Cohesive design and performance across the entire build
• Faster project delivery with a single accountable team
• Consistent quality control from groundworks to final finish

This joined-up delivery model ensures your orangery, extension, or renovation achieves the best of both worlds:

robust construction and high-performance glazing; delivered by specialists who understand both disciplines.

TECHNICAL AND PERFORMANCE FOCUS

Structural Integrity, Thermal Performance & Glazing Integration

Because we specialise in combining building works and glazing, we pay special attention to:

• Proper thermal breaks, insulation continuity and avoiding thermal bridging at glazing junctions
• Correct flashings, seals & waterproofing to prevent leaks where glass meets structure
• Engineered lintels, beams & supports sized for glazing loads and structural spans
• Use of high-performance glazing systems and compliance with U-value and energy targets
• Coordination of ventilation, drainage, drainage falls, condensation control

FREQUENTLY ASKED QUESTIONS

Will you handle planning permission / building regs?

Our teams can assist with what you require for your planning permission and can liaise with structural engineers to provide building regulation compliance.

How do you ensure the glazing integrates cleanly with new extensions?

We plan all junctions carefully (lintels, flashings, seals) and use compatible profiles / systems to ensure there’s no weak point or leak.

What timelines are typical?

Depending on the scale — a small orangery might take 8–12 weeks, a full extension could be 4–6 months. We provide a project schedule during quotation.

Can you match existing styles/materials?

Absolutely. We aim to blend new work with your property’s character — whether masonry, cladding, window style, etc.

What warranties or guarantees do you provide?

We stand behind structural work, glazing, and finishes. We’ll outline warranties in your contract and offer maintenance support.
