The real benefits of UPVC replacement windows

What are the benefits of having double or triple glazed UPVC replacement windows fitted, rather than say aluminium, composite or hardwood double glazed windows? In addition, why would property owners in Beds, Berks, Bucks, Hants, Herts, Middlesex, Oxon and Surrey choose Hazlemere Windows bespoke UPVC replacement windows over others available in the South of England?

Whilst less thermally efficient, less expensive UPVC windows rated B or C rated are available in the UK, Hazlemere only specify, supply and fit high quality â€ŔA” rated UK manufactured UPVC windows. Infact all Hazlemere UPVC double glazed and triple glazed UPVC casement, as well as tilt and turn windows are A Rated as standard. Their vertically sliding double glazed UPVC sash windows are also “A” rated.

Each UPVC casement window is individually made to order from scratch (nothing in stock), so every Hazlemere UPVC window is tailor made to each aperture. All side opening vents have high security dog bolts and an  easy clean/fire escape hinge fitted as standard, plus all opening vents on Hazlemere “A” rated UPVC windows have a lockable night vent facility.

All Hazlemere Windows UPVC frames are made from the finest extrusions and feature welded joints, with an attractive sculptured frame appearance inside and out. They have a 70mm deep multi chambered thermally broken frame, high security locking system and dog bolts on all opening vents. Internal glazing beads prevent removal of sealed units/panels from the outside. Toughened safety glass to BS6206 is fitted to all low-level glazing, and windows within 300mm of any door, or 800mm of any internal floor level.

All Hazlemere UPVC windows are constructed from high quality materials to ensure they offer excellent levels of thermal performance, plus both the 28mm wide double glazed sealed units and 36mm wide triple glazed sealed units reduce noise pollution by a slightly greater degree than standard 24mm wide aluminium or hardwood double glazed sealed units.

Hazlemere’s 28mm wide UPVC standard double glazed sealed unit is made up of 4mm/20mm/4mm, using a combination of low iron outer float or toughened clear or obscure safety glass, a black Swiss V warm edge spacer bar, 90% Argon filled, and an inner softcoat float or toughened glass pane. This double glazing specification achieves a centre-pane U Value of 1.2 W/m2K, and when tested with Hazlemere’s UPVC frames achieves a combined “A” rated U-Value of 1.4 W/m2K

Hazlemere’s 36mm wide UPVC triple glazed unit is 4mm/12mm/4mm/12mm/4mm, a combination of low iron outer, then a toughened middle glass pane as standard (to reduce any likelihood of cracking due to sharp temperature differentials), two black Swiss V warm edge spacer bars, 90% Argon filled, and an inner softcoat glass pane. This triple glazing specification achieves a centre-pane U value of 0.9 W/m2K, and when tested with Hazlemere’s â€ŔA” rated UPVC triple glazed windows achieves a combined U-Value of 1.0 W/m2K.

Like most high quality UPVC double glazing systems, all Hazlemere’s energy rated UPVC windows are available in real woodgrain effect single or dual colour foil finishes, with front doors, back doors, French doors and sliding patio doors in matching profiles.

The real benefits of replacement UPVC windows are simply therefore that they are more thermally efficient than aluminium or hardwood windows, are warmer to the touch than aluminium windows and usually cost far less.
