Stylish Windows

How energy efficient are modern windows?

Energy bills are a major concern for South Wales homeowners. Old single-glazed or timber-framed windows lose significant heat, driving up costs. Daimant installs systems with:

• A+ rated glazing – argon-filled units with low-emissivity coatings.

• Triple glazing options – providing superior insulation and soundproofing.

• Thermally efficient frames – multi-chamber uPVC and thermally broken aluminium.

According to the Energy Saving Trust, upgrading from single glazing to modern A+ rated double glazing saves up to £195 per year in a semi-detached home. In exposed South Wales areas like Barry or Bridgend, triple glazing can cut drafts and condensation even further.

How secure are modern windows?

Security is one of the most important features of replacement windows. Daimant installs:

• Multi-point locking systems – bolts lock into frames at multiple points.

• Child restrictors – prevent accidental openings.

• PAS 24 certification – enhanced UK security standards.

• Secured by Design options – police-backed security features.

• Laminated or toughened safety glass – resists forced entry.

Example: In Cathays, Cardiff, landlords installing PAS 24 windows met new rental standards while also reducing burglary risk in shared student houses.

What design and finish options are available?

Your windows should reflect your property’s character. Daimant offers:

• Frame colours – classic white, modern anthracite grey, black, or timber-look foils.

• Glazing types – frosted for privacy, acoustic for noise reduction, decorative for style.

• Materials – durable uPVC or slimline aluminium.

• Handles and hardware – stainless steel, chrome, brass, or matte black.

Examples:

• In Roath, Cardiff, a Victorian terrace upgraded with timber-effect flush sash windows, maintaining heritage looks.

• In Caerphilly new-build estates, homeowners often choose modern grey casement windows to match composite front doors.

• In rural South Wales cottages, vertical sliding sash windows keep the traditional aesthetic while providing modern insulation.

Casement Windows – Simple, Secure & Versatile

Casement windows remain the UK’s most popular choice. They open outward on side or top hinges, providing excellent ventilation.

• Ventilation benefits – side-hung casements catch breezes, while top-hung prevent rain entry.

• Energy efficiency – A+ rated double glazing reduces drafts.

• Security – shootbolt locking systems and child restrictors.

Casement windows are perfect for South Wales family homes, where flexibility and efficiency matter most.

Tilt & Turn Windows – Safe Ventilation & Easy Cleaning

Tilt & turn windows are popular in modern homes and apartments across Cardiff. Their dual-function design allows:

• Tilt mode – safe top ventilation, even in rain.

• Turn mode – inward opening for easy cleaning.

• Fire escape suitability – complies with UK safety regulations.

These windows are often installed in high-rise Cardiff apartments or Caerphilly extensions, where accessibility is key.

Vertical Sliding (Sash) Windows – Heritage Style with Modern Comfort

Vertical sliding sash windows are a must for conservation areas in Cardiff, such as Pontcanna, Roath, and Llandaff. Daimant installs modern sash systems with:

• Spring balance or cord & weight options.

• Double-glazed units for insulation while preserving appearance.

• Planning-friendly designs accepted in heritage zones.

Example: A townhouse in Pontcanna upgraded to double-glazed sash windows, cutting heating bills while retaining Georgian-style charm.

Flush Sash Windows – Timber-Look Finish for Traditional Homes

Flush sash windows replicate traditional timber designs, where the sash sits flat within the frame. They are perfect for:

• Heritage properties – timber-effect finishes approved in Cardiff conservation areas.

• Modern builds – sleek, uniform lines for contemporary designs.

• Low maintenance – uPVC construction without painting or sanding.

Example: In Penarth, a Victorian home installed cream flush sash windows to meet conservation standards while reducing maintenance costs.

How much do replacement windows cost in South Wales?

Prices vary depending on style, material, and glazing:

• Casement Windows – £350–£600 per window.

• Tilt & Turn Windows – £450–£750.

• Vertical Sliding (Sash) Windows – £700–£1,200.

• Flush Sash Windows – £650–£1,000.

While sash and flush sash are higher in cost, they preserve property value in conservation areas where authenticity is critical. Estate agents estimate that upgrading windows can add up to 10% to home value in South Wales.
