Aluminium Flush Sash Windows
Our exclusive flush-fitting aluminium sash windows boast industry-leading slim sightlines for panoramic views. The ultra-slim reinforced frames are precision-engineered for uncompromising security and thermal optimisation to match strict energy efficiency ratings.
Why choose aluminium sashes?
- Durability – Aluminium is highly resilient against weathering, and it is impervious to pest damage and rot.
- Security – The slim yet strong aluminium frames resist forced entry, while multi-point locks provide reinforced security. Advanced glass options include laminate for smash resistance.
- Energy efficiency – Thermally optimised aluminium frames feature thermal breaks that improve insulation. High-performance glazing reduces heat loss for lower heating bills.
- Low maintenance – Unlike timber, aluminium flush sash windows do not require painting, staining, or varnishing to protect appearance or performance. A simple soap and water clean is all they need.
- Unrivalled views – Extra slim 50mm aluminium frames allow huge glass areas for increased natural light and panoramic views.
- Weather resistance – Triple weather seals prevent rainwater leakage, while the aluminium material is unaffected by exposure to rain, wind, snow, and UV rays.
- Versatility – Aluminium offers an extensive choice of frame finishes and hardware colours to match diverse architectural styles. Custom sizing is also available.
How do they compare to timber?
Aluminium flush sash windows replicate the aesthetic appeal of traditional timber sash windows yet deliver better performance, longevity, and cost savings with a slimmer profile.
Compared to timber, aluminium wins hands down for durability and weather resistance. Aluminium flush sash windows will easily outlast regular sanded and varnished timber windows with no maintenance whatsoever.
Are these windows energy-efficient?
Increasingly stringent sustainability regulations demand improved energy efficiency from windows. Our aluminium flush sash windows meet and surpass modern performance standards. Thermally optimised frames, advanced weather sealing, and high-performance glazing insulate against heat loss more effectively than alternatives.
By installing our energy-efficient flush sash windows, you can reduce home heating bills by up to 20% while doing your bit for the environment.
Heritage Sliding Sash Windows
Heritage sliding sash windows classically replicate the original Victorian and Georgian windows, retaining all their elegant period details in durable, low-maintenance uPVC.
What do Heritage sliding sash windows offer?
- Authentic styling – Painstakingly reproduces fine details like slender frames, rounded putty line glazing, and decorative horns.
- Energy efficiency – Thermal performance is vastly improved over original single-glazed timber but retains all the period charm.
- Enhanced solar gain – Maximise free heating from sunlight thanks to the large glass expanses of sash windows.
- Sound insulation – Effective at reducing noise pollution from traffic and other external noises for peaceful indoor relaxation.
- Robust security – Multi-point locks and reinforced frames resistant to forced entry with advanced glass options for smash resistance.
- Low maintenance – unlike traditional wooden sash windows, uPVC construction requires no sanding, painting, or staining.
- Weatherproofing – Compression seals prevent rainwater ingress, while the uPVC frames are unaffected by exposure to rain, wind, snow, and UV rays.
- Durability – The uPVC frame and glass units are inherently resilient to rot, warp, and pests, leading to a lifespan above 30 years.
Why pick Heritage over a standard sliding sash?
Heritage provides a truly authentic look impossible to achieve with regular sash windows. Meticulous detailing like slender putty lines, decorative horns, deep bottom rails, and wood effect joints recreate the traditional timber window aesthetic.
Of equal importance is performance. Beneath the period styling, Heritage sliding sash windows incorporate double or even triple glazing, draughtproofing, and weather seals that the original windows sorely lacked. This preserves charm while transforming comfort and energy efficiency.
Which sliding sash best suits my home?
For Victorian, 1930s, and other classically styled homes, classic sash windows align best with proportions in keeping with the period.
Thick frames create a bold, modern look, ideally complementing new builds or contemporary renovations. Porthole styles introduce a new dynamic for rooms lacking character while keeping operational functionality. The windows tilt in, making glass cleaning straightforward, while Georgian bar detailing can be added for an extra traditional touch.
Additionally, we offer single-glazed panes to repair existing sash windows alongside replacement double-glazed units to upgrade glazing without replacing full frames, allowing cost-effective upgrades in existing sash boxes.
KGlazing transformed our home into a masterpiece.
