Choosing the Right Windows
KingsRock Windows
1. Introduction
Selecting the right windows is a vital decision impacting aesthetics, performance, lifespan, and return on investment. Whether you're refurbishing a heritage home or building new, you’ll typically choose from three main categories:
Timber
Aluminium‑clad timber (alu‑clad)
Timber‑look uPVC
Let’s explore each of the advantages, drawbacks, and real-world performance from trusted manufacturers.
2. Timber Windows
What are they?
Made from solid or engineered woods often redwood or Accoya, these windows harness natural warmth and authenticity.
Advantages:
Longevity: High-quality timber (e.g., Accoya) can last 50–60+ years with proper maintenance, well above typical uPVC lifespans of ~30 years
Heritage appeal: Perfect for conservation or period properties
Energy efficiency: Natural wood is a great insulator, boosted further with double or triple glazing
Disadvantages:
Maintenance: Requires cleaning plus redecoration every 5–10 years—factory coatings have stretched cycles to 10+ years in some cases
Cost: Higher upfront price, though excellent durability can make timber cost-effective long term
Stats at a glance:
50–60 + years lifespan with quality timber and care
Maintenance redecoration intervals: prep and repaint every 5–10 years; annual clean recommended
3. Alu‑Clad Timber Windows
What are they?
A timber core encased externally in aluminium—offered by brands like Velfac and Rationel.
Advantages:
Low maintenance: Aluminium exteriors resist weathering for example Velfac windows are virtually maintenance-free woth annual cleaning/oiling, with lifespans up to 60 years!
Durability & performance: Aluminium resists rot, pests, and corrosion, Rationel AURAPLUS extends timber life by 20+ years
Energy efficiency: High-performance glazing with U‑values as low as 0.8 W/m²K (Velfac) and triple‑glazed Rationel achieving 0.79 W/m²K
Security & noise reduction: Rationel delivers 42 dB noise reduction and Secured by Design credentials; Velfac windows are burglary‑resistant
Disadvantages:
Higher cost upfront: Premium material and engineering come with a premium.
Design aesthetic: Exterior aluminium may feel less traditional than pure timber—though interior finishes remain natural wood.
4. Timber‑Look uPVC Windows
What are they?
Modern uPVC windows designed to mimic timber, like Roseview’s award-winning Rose Collection.
Advantages:
Low cost & low maintenance: Very affordable and easy to clean with minimal upkeep.
Suitable for conservation areas: Roseview’s Heritage/Ultimate models have planning consent in conservation zones
Eco wins: PVC is made partly from salt, recyclable, and has lifespans of ~35 years
Disadvantages:
Shorter lifespan & non‑renewable finish: Less long-lasting; cannot be re-stained like timber
5. Comparing Options for Refurbishment vs New Build
When choosing windows, your decision will often depend on whether you’re working on a refurbishment or a new build. For heritage refurbishments, timber windows are usually the best fit thanks to their authenticity, natural material, and compliance with conservation requirements. They’re ideal for period homes and listed properties, especially when matched with traditional glazing bars and profiles. However, if low maintenance is a priority, timber-look uPVC can be a great alternative, particularly in conservation areas where authentic appearance is needed without the upkeep.
For new builds, the choice tends to revolve around performance, aesthetics, and budget. Alu‑clad windows shine in this space, offering the warmth and beauty of timber inside with the weatherproof durability of aluminium outside. They deliver top-tier energy efficiency—often achieving U-values below 0.8 W/m²K—and require minimal maintenance. That said, timber is still a strong contender in new builds that aim for sustainability or a softer, more natural finish. Timber-look uPVC remains a solid budget-friendly choice for developers looking to balance appearance and cost.
Ultimately, if you're aiming for authenticity and longevity, timber is ideal. If you want durability and low maintenance, alu‑clad is your go-to. And if you’re working within tight budgets, timber-look uPVC offers visual appeal without the premium price tag.
Guidance:
For authentic period restoration → choose KingsRock Joinery for timber windows.
For long‑term ease, durability, and energy efficiency → Velfac or Rational alu‑clad is unmatched.
On budgets, preserving traditional look with low upkeep → Roseview’s timber‑look uPVC is superb.
