Aluminium windows across Guildford
Large aluminium windows that reach low down, such as floor-to-ceiling glazing, need safety glass. In England, Approved Document K treats glazing within 800mm of the floor as a critical location, so those panes are usually toughened or laminated and permanently marked to show their safety classification.
Powder-coated aluminium does not need painting, but it does need cleaning. Wash frames with warm water and a mild detergent a few times a year, rinse, and avoid abrasive pads or solvents. Clean more often near the sea or busy roads, where salt and grime sit on the surface for longer.
Aluminium is strong enough to hold large, heavy glass units in narrow frames, so sightlines are slimmer than uPVC of the same size. That means more glass and more daylight from the same opening, which suits modern extensions, wide picture windows and slim replacements for old steel windows.
Aluminium windows can be fitted with trickle vents in the frame head, which matters because in England, Approved Document F expects ventilation after window replacement to be no worse than before. The glazier records the existing vents at survey and sizes new ones to suit each room.

- Coast
- Guildford is well inland, around 48 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Guildford the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Slim aluminium frames let more daylight through the same opening. Large south or west-facing panes can overheat rooms, so solar-control glass may help, while north-facing rooms benefit from high light-transmission low-E glass that keeps heat in during short winter days.
- Access and setting
- Large aluminium units are heavy, so city jobs need planned unloading, parking and sometimes lifting gear or extra hands for upper floors. Flats need freeholder consent and planning permission, and conservation areas often control frame colour and glazing bar patterns.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

In England, replacing a whole window, roof window or glazed external door is building work. It has to be notified to building control, either by an installer registered with a competent person scheme such as FENSA or Certass, or through a building notice to the council. Replacing only the glass in an existing frame is a repair and is not notifiable.
Specification choices
Tilt and turn
Inward-opening sashes that tilt for secure ventilation or swing open for cleaning and escape, useful for flats and high floors.
Dual-colour powder coat
A different colour inside and out, such as anthracite grey outside with white inside, from a wide range of RAL colours and textures.
Glass upgrades
Triple glazing, laminated acoustic glass, solar-control coatings or obscure glass, chosen per window to suit the room and elevation.
Aluminium Windows in Guildford: questions
Are aluminium windows secure?
Aluminium windows can be very secure, because the metal is strong and the frames carry multi-point locks, internal glazing beads and lockable handles. For easily accessible windows in new homes in England, Approved Document Q expects PAS 24 security. Asking for windows tested to that standard is a good benchmark when replacing ground-floor windows in an existing home.
What guarantee do aluminium windows come with?
Manufacturer guarantees apply to the frames, powder coating, hardware and sealed units, and the terms are confirmed in writing. Coating cover often depends on the site environment and on regular cleaning, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, before you agree to go ahead.
How do I look after powder-coated aluminium windows?
Clean powder-coated aluminium windows with warm water and a mild, non-abrasive detergent a few times a year, then rinse and dry. Avoid scouring pads, solvents and pressure washers close to the seals. Keep drainage slots clear and put a little light oil on hinges and locking points. Near the coast, more frequent washing removes salt deposits.
How much do aluminium windows cost?
The cost of aluminium windows depends on the number and size of windows, the profile system, how many sashes open, the colour and finish, the glass and the access. They generally cost more than equivalent uPVC because of the material and factory coating. See the guide prices for typical ranges; the written quote fixes the price for your exact specification.
