Top 5 Window Styles for Energy Efficiency in NI

With Northern Ireland's climate and rising energy costs, choosing the right windows can make a significant difference to your home's thermal performance and heating bills.

1. Flush Sash Windows

Flush sash windows sit flush with the frame, eliminating gaps and draughts. With A+ energy ratings and modern glazing technology, these are perfect for new builds focused on energy efficiency.

Key Benefits:

Minimal cold bridging
Superior weather sealing
U-values as low as 0.8 W/m�K
Contemporary aesthetics

2. Casement Windows with Multi-Chambered Frames

Modern casement windows with multi-chambered uPVC profiles trap air for excellent insulation. When combined with low-E glazing, they offer outstanding thermal performance.

Why They Work: Multiple air chambers create thermal barriers, reducing heat loss by up to 70% compared to single-glazed windows.

3. Tilt & Turn Windows

These European-style windows offer exceptional sealing when closed, with compression gaskets all around the frame. Perfect for exposed locations in Northern Ireland.

Ideal For: Coastal properties, upper floors, and areas with high wind exposure.

4. Triple-Glazed Sliding Sash

Traditional styling doesn't mean compromising on efficiency. Modern sliding sash windows can now accommodate triple glazing for maximum thermal performance while maintaining heritage aesthetics.

Perfect Match: Period properties seeking energy upgrades without losing character.

5. REHAU Total70 System

Our REHAU Total70 windows feature a 70mm frame depth specifically designed for Northern Ireland's climate. They achieve Passive House standards when specified correctly.

Technical Excellence: 6-chamber profile, reinforced frame, and warm-edge spacer bars.

Expert Tip from Bespoke Windows NI

"Energy efficiency isn't just about the window style�it's about proper installation, correct glazing specification, and ensuring airtightness. We always conduct a thermal assessment before recommending specific systems for your home."

What to Consider

When choosing energy-efficient windows for your Northern Ireland home, consider:

U-Value: Look for 1.2 W/m�K or lower
Glazing: Low-E coating and argon gas fill
Installation: Professional fitting is crucial
Ventilation: Balance efficiency with air quality
Building Regulations: Ensure compliance with NI standards

Every home is different. Our team can assess your property and recommend the most energy-efficient window solutions for your specific needs and budget.

Composite vs uPVC Doors: Which Is Best for Your Home?

Choosing between composite and uPVC doors is one of the most common questions we hear. Both offer excellent performance, but which is right for your Northern Ireland home?

Composite Doors: Premium Performance

Composite doors are constructed from multiple materials�typically a timber core, insulating foam, and a GRP (glass-reinforced plastic) skin. This creates an incredibly strong, thermally efficient door.

? Composite Door Advantages

Superior Security: 48mm+ thickness, solid core, Secured by Design approved
Authentic Look: Replicates traditional timber appearance
Excellent Insulation: Foam core provides outstanding U-values
Low Maintenance: GRP skin won't warp, crack, or fade
Durability: 35+ year lifespan
Design Options: Hundreds of styles, colours, and glazing patterns

? Composite Door Considerations

Higher Cost: Typically 30-50% more expensive than uPVC
Weight: Heavier, requires robust hinges
Lead Time: Often made to order, 2-3 week wait

uPVC Doors: Value & Versatility

Modern uPVC doors have come a long way. Multi-chambered profiles and reinforced frames deliver impressive performance at an accessible price point.

? uPVC Door Advantages

Affordable: Excellent value for money
Low Maintenance: Simple to clean, never needs painting
Weather Resistant: Ideal for NI's wet climate
Energy Efficient: Multi-chamber profiles trap heat effectively
Quick Installation: Usually available within 1-2 weeks
Colour Options: White, woodgrain, anthracite, and more

? uPVC Door Considerations

Aesthetics: Less authentic timber appearance
Thickness: Typically 44mm vs 48mm+ for composite
Perceived Quality: May appear less premium

Which Should You Choose?

Choose Composite If:

You want the ultimate in security and insulation
Authentic timber appearance is important
You're replacing a front door on a period property
Budget allows for premium investment
You value long-term durability (35+ years)

Choose uPVC If:

You need excellent performance at a lower cost
Replacing multiple doors (back, side, patio)
Quick installation is important
You prefer a clean, modern look
Budget is a primary consideration

Our Recommendation

"For front doors, we usually recommend composite�it's your home's first impression and main security point. For back or side doors, uPVC offers fantastic value. Many customers do a composite front with uPVC throughout the rest of the house."
