Which Property Types Are Best for Timber vs UPVC Windows?

Best Properties for Timber Windows

  • Period Homes (Victorian, Georgian, Edwardian): Timber windows are the traditional choice for period properties due to their classic, elegant appearance and ability to maintain the authenticity of the building’s style. The warmth and charm of timber complement the design of older homes.
  • Cottages & Rural Properties: Timber windows suit rural and countryside homes well, where a natural aesthetic is often preferred to match the organic surroundings. The rustic look of timber enhances the quaint, rustic charm of cottages.
  • Conservation Areas: Many conservation areas have strict guidelines that require properties to retain their historical character. Timber windows are often the only option for homeowners who need to comply with these rules. The ability to refurbish and restore timber windows is also an important consideration for those living in listed buildings or conservation zones.

Best Properties for UPVC Windows

  • Modern Homes & New Builds: UPVC windows are commonly found in contemporary properties and new builds. The sleek, modern look of UPVC windows complements the clean, minimalist design of these homes. They are also designed to be energy-efficient, which aligns with the needs of newer buildings.
  • Rental Properties & Commercial Buildings: UPVC windows are often the preferred choice for landlords and property developers. They are low-maintenance, cost-effective, and durable, making them ideal for rental properties and commercial buildings, where long-term investment and minimal upkeep are key considerations.
  • Homes in Coastal or High-Moisture Areas: UPVC is highly resistant to moisture, making it perfect for properties located in coastal areas or regions prone to high humidity. Timber windows may warp or rot in these conditions, but UPVC windows remain weatherproof and corrosion-resistant, making them a more durable option for such environments.

Timber vs UPVC Window Styles

Both timber and UPVC windows come in various styles, each offering unique features and benefits. The style of window you choose will depend on the aesthetic and functionality you’re aiming for in your home.

  • Casement Windows: Casement windows are hinged at the side, opening outward like a door. They are one of the most popular window styles due to their excellent ventilation capabilities. Whether in timber or UPVC, casement windows are easy to open and close, and they offer a wide view of the outside. They are also ideal for hard-to-reach areas because they don’t need to slide up or down.
  • Sash Windows: These are traditional sliding windows, commonly found in period homes such as Victorian or Georgian properties. Timber sash windows are especially popular because they align with the historical architecture of these buildings. However, UPVC sash windows are now available and offer the same style with modern benefits like better insulation and security features.
  • Tilt and Turn Windows: These windows are a modern style that can open inward from the top or side. They offer versatility by allowing for easy cleaning, while also providing good ventilation. Timber tilt and turn windows offer a traditional finish, while UPVC tilt and turn windows provide a sleek, low-maintenance solution with better weather resistance.

View & Natural Light Intake

  • Timber windows often have thicker frames, slightly reducing glass surface area.
  • UPVC windows have slimmer frames, allowing more natural light into the home.

Insulation & Energy Efficiency

Glazing Options for Timber and UPVC Windows

Glazing TypeFeaturesEnergy Efficiency RatingAverage Pricing (per window)
Single GlazingA single pane of glass, typically used in older homes, offering basic insulation.E – Low£80 – £120
Double GlazingTwo panes of glass with a gap in between, offering improved insulation and soundproofing.B – Medium£150 – £200
Triple GlazingThree panes of glass, providing superior insulation, energy efficiency, and noise reduction.A – High£250 – £300

Self-Cleaning GlassGlass with a special coating that uses sunlight and rain to clean the surface automatically.A – High£300 – £350

  • Single Glazing: Commonly found in older homes, this is the most affordable option. However, it offers poor energy efficiency, making it less ideal for homeowners wanting to reduce heating costs.
  • Double Glazing: This is the standard for most modern homes, improving energy efficiency and reducing external noise. Energy efficiency ratings tend to range from B to A, offering a significant improvement over single glazing
  • Triple Glazing: Ideal for homes located in colder climates or for those who want the highest insulation and energy efficiency. Although it’s the most expensive option, it offers superior noise reduction and keeps homes warmer.
  • Low-E Glazing: This type of glazing is designed with a microscopic coating that reduces heat loss while letting in natural light. It has the best energy efficiency rating of all options, making it a great investment for those looking to reduce heating costs while keeping interiors well-lit.
  • Self-Cleaning Glass: This is a premium option that makes cleaning windows easier. Although it comes with a higher price tag, it offers the benefit of maintaining clear windows with minimal effort and is suitable for homeowners who want a low-maintenance solution.

Ventilation & Draughts

  • Timber windows may develop gaps over time, leading to draughts.
  • UPVC windows have airtight seals, reducing draughts and improving ventilation control.

Security Features

  • UPVC windows often include multi-point locking systems, making them highly secure.
  • Timber windows can be reinforced with additional locks for enhanced security.

Maintenance & Longevity

Maintenance AspectTimber WindowsUPVC Windows
CleaningRequires regular repainting and sealingEasy to clean with soap and water
Wear & TearCan rot, warp, or crack if not maintainedDurable, resistant to weathering and UV
Longevity50-60 years with proper care20-30 years

  • Timber Windows: If well-maintained (repainted and resealed regularly), timber windows can last 50-60 years, and they often add value to period properties due to their classic look and high-quality material.
  • UPVC Windows: While UPVC windows are more low-maintenance, they generally last 20-30 years before showing signs of wear. UPVC does not require repainting and is resistant to moisture, but UV rays can cause fading over time, which may affect their appearance. However, they still offer long-lasting durability with minimal upkeep.

In terms of better longevity, timber windows can offer a longer lifespan if maintained properly. UPVC windows, however, are the more low-maintenance option that still provides reliable durability for a few decades.

Costs & Installation

The price of new windows depends on several factors, such as the size, material, glazing options, and the complexity of installation. Below, we’ll compare the average prices of timber and uPVC windows:

FAQs

Are uPVC windows better than wood?

uPVC windows offer several advantages over timber windows, including lower maintenance costs, better insulation, and a longer lifespan. They are resistant to weathering, do not need painting, and are generally more energy-efficient. However, timber windows can provide a more classic, natural aesthetic and are often preferred for heritage homes or those aiming for a more traditional look.

Are timber windows worth it?

Timber windows are worth it for those who value traditional craftsmanship, natural aesthetics, and the potential for long-term durability with proper care. While they do require more maintenance (such as painting and sealing), they can add significant charm and value to a property, particularly in older homes. They also provide excellent insulation when properly maintained.

Can I replace timber windows with uPVC?

Yes, you can replace timber windows with uPVC windows. This is a common choice for homeowners looking to reduce maintenance or increase energy efficiency. However, you should consider the aesthetic impact, especially if your home is in a conservation area or has heritage value, as uPVC may not always match the look of timber windows.

Do people still use wood windows?

Yes, people still use wood windows, especially in older properties, conservation areas, or for those who prefer a more natural, traditional look. Timber windows are highly valued for their aesthetic appeal, insulation properties, and long lifespan, although they require more maintenance than uPVC alternatives.

Do uPVC windows look cheap?

uPVC windows can sometimes be perceived as looking cheaper compared to timber windows, particularly if the uPVC is of lower quality or poorly installed. However, high-quality uPVC windows come in a variety of finishes, including wood-effect options, which can mimic the look of timber while offering the practical benefits of uPVC. The appearance largely depends on the quality of the material and the installation.
