Aluminium windows across March
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.
Aluminium frames are usually finished with polyester powder coating, baked on at the factory in a choice of RAL colours and in matt, satin or textured finishes. Dual-colour frames are possible, such as anthracite grey outside and white inside, so the windows can suit both the street and the room.
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.
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.
What's included
- Sealed double or triple glazed units to specification
- Written guarantee terms and advice on building regulations sign-off
- Thermally broken aluminium frames powder coated to order

About March for this job
- Postcodes covered
- PE15 and the surrounding area, including Wisbech, Whittlesey and Ely
- Coast
- March is well inland, around 32 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In March the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 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
- Rural homes often mix old stone walls with modern extensions, and aluminium suits both when profiles are chosen carefully. Irregular openings are measured individually, and exposed sites benefit from systems with high weather ratings and well-sealed joints against driving rain.
- 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.

Aluminium Windows in March: questions
How long does it take to install aluminium windows?
Most single windows are fitted within a day, and a typical house takes a few days on site depending on the number of windows and the access. The longer part is manufacturing, because frames are cut, coated and glazed to the survey sizes. The expected lead time is confirmed in writing when you accept the quote.
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.
Are aluminium windows better than uPVC?
Neither is better for every home; they suit different priorities. Aluminium gives slimmer frames, larger glass areas, a hard-wearing powder-coated finish and a wide colour choice. uPVC usually costs less and has chunkier frames. Both can meet the energy standard for replacement windows when specified correctly, so compare the certified ratings, the look you want and the guide prices.
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.
