Specifying glazing for housing developments is a different challenge to fitting out a single home. When you are working across multiple plots, every decision around sizes, colours, lead times and building regulations gets multiplied. Get it right and the project runs to schedule. Get it wrong and you face delays, snagging and ordering errors that eat into your margin.
This guide is written for developers, contractors and architects who need aluminium windows and aluminium doors that perform consistently at scale. We will cover repeatability, lead time planning, drawing coordination, Part L and Part F compliance, and why supplier support matters when you are managing dozens of plots at once.
Why aluminium suits modern new build projects
Aluminium frames offer a slim sightline, a wide range of styles and a long service life with low maintenance. For a modern new build, that combination is hard to beat. Aluminium windows carry larger panes of glass than most uPVC windows because the frames are stronger, which means more daylight and a cleaner finish across an elevation.
On thermal performance, today’s aluminium systems use polyamide thermal breaks to reduce heat transfer through the frame. Paired with double glazing or triple glazing, you get the thermal efficiency needed to meet current building regulations while keeping the energy bills down for potential buyers. The benefits of double glazing, two layers of glass separated by a cavity filled with inert gas such as argon, include better energy efficiency, noise reduction and fewer cold spots around the home.
Consistency and repeatability across plots
The biggest gain on a multi-plot development comes from standardising sizes. Where house types repeat, your glazing schedule should repeat too. Standardising window and door sizes across plots delivers real cost savings because it simplifies ordering, reduces the risk of mistakes and speeds up installation on site.
A few practical points:
- Group identical house types and confirm that the glass options, colours and opening configurations match across each one.
- Keep your casement windows and aluminium doors to a set palette of sizes wherever the design allows.
- Agree colours early. A single RAL colour run across the whole development looks sharper and avoids mismatched batches.
- Repeatability also helps your fitters. When the same units appear plot after plot, installation becomes quicker and easier.
Coordinating drawings before manufacture
Most ordering errors start at the drawing stage. Before anything reaches the factory, structural openings, lintel positions and cill details need to be checked against the manufacturing schedule. A single transposed dimension repeated across 40 plots is an expensive mistake.
Good practice is to coordinate architectural drawings with the manufacturing schedule and sign off a sample plot first. This gives you a reference for the whole site and catches problems before they multiply. At Midland Aluminium, our team checks specifications and supports technical coordination so the schedule that goes into production is the one you actually need.
Meeting Part L and Part F
Two sets of building regulations matter most for glazing on housing developments.
Part L covers energy efficiency and limits heat loss through the building fabric. New windows must meet minimum thermal standards, which influences your choice of glazing and frame. You can read the current guidance on the GOV.UK Approved Document L page.
Part F covers ventilation, including the trickle vents now required in most new windows. You can find the detail in Approved Document F. This is where our hood vent feature earns its place. The concealed hood vent on our flush aluminium windows hides the trickle vent, so you stay compliant with Part F without the visible vent bar that developers and buyers dislike.
Meeting both documents at the same time, energy efficiency under Part L and ventilation under Part F, is far easier when your supplier understands how the two interact.
Lead time planning that protects your programme
Lead times drive everything on a phased development. Order too early and you tie up cash and storage. Order too late and the glazing holds up the whole programme.
Our lead times start from just 7 days on bifold doors and run to 2 to 3 weeks on most stock colour aluminium products. We deliver free across the UK on weekly routes, direct to site, with no minimum order. That means you can release plots in phases and have units arrive when each phase is ready, rather than storing a whole site’s worth of frames in one go.
We also turn quotes around within 24 hours, so you can price work and plan procurement without waiting days for figures.
Our range of aluminium windows and doors
Midland Aluminium supplies a full range built around Smart Systems profiles:
- Flush aluminium windows with the concealed hood vent and integrated drainage covers.
- Casement windows in aluminium and uPVC for projects with a mixed specification.
- Heritage ranges including Timberlook wood-effect windows and Steel-Look windows and doors for developments with a traditional aesthetic.
- Bi-fold doors using Visofold 1000
- Sliding systems and aluminium doors across the Visoglide and Alitherm ranges.
We supply both aluminium and uPVC frames, so you can match the right windows to each plot type and budget while keeping a single, reliable trade supplier behind the whole scheme.
Reducing snagging on multi-plot projects
Snagging multiplies on volume work. The fix is accurate scheduling, consistent products and a supplier who supports the technical detail. With standardised sizes, checked drawings and units that arrive correctly labelled per plot, your handover list stays short and your retentions get released faster.
Frequently asked questions
What lead times apply to aluminium glazing for housing developments?
Bifold doors start from 7 days and most stock colour aluminium products take 2 to 3 weeks. Phased ordering lets us match deliveries to your build programme across multiple plots.
Do your windows meet Part L and Part F?
Yes. Our systems meet current thermal standards under Part L, and our concealed hood vent provides Part F compliant ventilation without a visible trickle vent bar.
Can you match colours across a whole development?
Yes. We supply a wide range of RAL colours and recommend confirming a single colour run early so every plot matches.
Do you supply both aluminium and uPVC?
Yes. We supply roughly 80% aluminium and 20% uPVC, so you can specify the right system for each house type from one supplier.
