Traditional sash windows are a beautiful feature of many Thanet homes — from seaside terraces in Margate to period townhouses in Broadstairs and Ramsgate. But old timber sashes can often mean drafts, rattles and high energy bills.
That’s where modern double glazed sash windows come in. At Clear Fast Glass, we design, supply and install double glazed uPVC and timber-effect sash windows across Thanet, giving homeowners classic aesthetics with 21st-century performance.
Quick answers
Are sash windows still available in double glazing?
Yes — modern uPVC sash windows are double glazed by default and can even replicate original Georgian or Victorian profiles.
Can sash windows be energy-efficient?
Absolutely. With quality glazing and seals, new sash windows can perform similarly to other double glazed units — warmer in winter, cooler in summer.
Do you install sash windows in conservation areas?
Yes, where design and appearance rules are met. Clear Fast Glass supplies heritage-look sash windows suitable for conservation-style properties around Thanet.
Why homeowners in Thanet love sash windows
Thanet’s housing stock is rich in Victorian, Georgian and Edwardian properties, many of which originally featured sliding sash windows. New double glazed sash designs let you keep the same heritage look — but with:
- Better insulation (double glazing + modern seals)
- Reduced condensation and drafts
- Smooth slide operation (no more sticking sashes)
- Easy-clean tilting mechanisms
- Long-lasting uPVC or timber-look frames
Clear Fast Glass fits sash windows designed to maintain traditional character while dramatically improving energy efficiency.
The benefits of double glazed sash windows
1. Energy savings
Double glazing keeps warm air inside and cold air out, lowering energy bills and creating a more comfortable indoor temperature.
2. Noise reduction
Perfect if you live near roads, the seafront, or busy town centres like Margate or Ramsgate — double glazing significantly cuts outside noise.
3. Low maintenance
uPVC sash windows don’t need painting and are resistant to rot, warping, and swelling — ideal for coastal homes.
4. Security
Modern locking systems and reinforced frames provide solid peace of mind. Clear Fast Glass offers sash windows with secure locking systems and robust frames.
5. Heritage appearance
Slim sightlines, woodgrain finishes, and authentic detailing mean you can preserve your home’s charm while enjoying modern comfort.
