Windows, Glazing & Blinds
Windows and blinds in a retail shop are not just for looks; they are part of the building envelope, security, energy efficiency, and customer experience. Below is a full breakdown of what’s typically included and why.
Windows – Structure and Placement
Purpose
- Provide natural light, ventilation, visual connection with the street, and display opportunities.
- In retail, windows are also part of branding, so their construction and specifications matter.
- o Shopfront Glazing (Full-Height Glass): Tempered/laminated safety glass, 10–12 mm thick for strength and security.
- o Fixed Windows: Non-opening panels to maximize visibility and minimize maintenance.
- o Opening Casement Windows: Often used in staff areas, kitchens, or back rooms for ventilation.
- o Fire-Rated Windows: Required where regulations demand escape routes.
- o Aluminum Frames: Durable, slim sightlines, powder-coated for corrosion resistance.
- o UPVC Frames: Cost-effective, good insulation but bulkier.
- o Timber Frames: Common in heritage areas.
- o Comply with Part L (energy efficiency) of UK Building Regulations.
- o U-values typically 1.4–1.6 W/m²K for double glazing.
- o Safety glazing to BS EN 12150 or BS EN 14449 standards.
Shopfront Glazing Details
• Glass Specification
- o Large panes of double-glazed units with low-emissivity coatings.
- o Laminated inner panes for security and safety.
- o Optional solar control coatings to reduce glare and fading.
- o Aluminum mullions and transoms fixed to structure.
- o Silicone joints or dry gaskets to seal.
- o Thermally broken profiles to minimize heat loss.
- o Low-threshold automatic sliding or swing doors (Equality Act compliant).
- o Manifestation (stickers/frosting) for visibility and safety.
Blinds – Types and Functions
- • Roller Blinds: Simple, robust, ideal for shopfronts (manual or motorized).
- • Vertical Blinds: For side windows or office areas.
- • Blackout Blinds: Used in fitting rooms, back offices, or AV display areas.
- • Solar Control Blinds: Reduce heat/glare while maintaining visibility.
- o Fire-retardant fabrics (BS 5867 Part 2 compliant).
- o UV-stable, easy to clean.
- o Aluminum or steel roller tubes for strength.
- o Manual chain or crank-handle systems for smaller windows.
- o Electric/motorized blinds for large areas or integration with building management systems.
Security Measures
- • Security shutters or grilles installed behind or outside glazing.
- • Laminated glass for resistance against forced entry.
- • Blinds combined with security mesh/screens where required.
Ventilation & Condensation Control
- • Trickle vents in frames to maintain airflow.
- • Opening panels or louvres for natural ventilation in staff/non-public areas.
- • Sealed frames with drainage channels to prevent leaks.
