Edinburgh & the Lothians: slim aluminium windows

Modern aluminium window frames contain a thermal break: strips of low-conductivity material, usually polyamide, that separate the inner and outer aluminium. Without it, heat passes straight through the metal. Older aluminium windows made without thermal breaks are a common cause of cold frames and streaming condensation.

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 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.

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.

What applies in Edinburgh & the Lothians

Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.

Listed buildings in Scotland need listed building consent for most changes to historic windows; Historic Environment Scotland publishes guidance on traditional windows.

Edinburgh & the Lothians has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Salt air attacks metal finishes, so aluminium windows near the coast need a coating and pretreatment suited to marine exposure, stainless or protected hardware, and more frequent washing. Check that the coating terms allow for a coastal site before ordering.

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.

Aluminium Windows in Edinburgh & the Lothians: questions

What colours can aluminium windows be?

Aluminium windows can be powder coated in almost any RAL colour, in matt, satin, gloss or textured finishes, and many systems offer a different colour on each side. Anthracite grey, black and white are common choices, but heritage greens, creams and bronze tones are available too. Special colours can extend the manufacturing lead time, which is confirmed with the quote.

Do aluminium windows get condensation on the frames?

Modern thermally broken aluminium windows are far less prone to frame condensation than older aluminium windows made without a thermal break. Condensation can still form on any window if a room is humid and poorly ventilated, so trickle vents, extractor fans and sensible heating still matter. Warm-edge spacer bars also help keep the edges of the glass warmer.

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.
