Timber vs uPVC Roof Windows: Which Is Better?

May 2026

Choosing the right roof window can make a huge difference to the look, comfort and practicality of your home. But once you have decided on the size, glazing and opening style, there is another important choice to make, which internal finish should you choose? 

For many homeowners, the decision starts with timber vs uPVC roof windows. However, the choice is now more detailed than that. Today, most roof window ranges include several finish options, including: 

• White-painted timber roof windows 

• Natural pine timber roof windows 

• PVC roof windows 

• White polyurethane roof windows 

Each option has its own benefits, drawbacks and ideal room types. In this guide, we explain the differences between timber, PVC and white polyurethane roof windows so you can choose the best option for your home.

What Are Timber Roof Windows? 

Timber roof windows have an internal frame made from wood, usually pine. They are popular because they offer a strong, high-quality feel and a warm, natural appearance. 

Traditionally, natural pine was the standard timber finish. Today, however, white-painted timber roof windows have become the more common choice for many homes. They offer the same timber construction but with a cleaner, brighter finish that blends well with white ceilings and modern interiors. 

Natural pine is still available from several major roof window brands, including RoofLITE+, FAKRO and Keylite, while VELUX has moved more strongly towards white painted and white polyurethane finishes as standard options. 

What Are uPVC Roof Windows? 

uPVC roof windows, often listed as PVC roof windows, are designed for durability, easy cleaning and moisture resistance. Instead of a painted timber frame, they use PVC profiles, which makes them especially practical in rooms where humidity is a concern. 

PVC roof windows are commonly chosen for bathrooms, kitchens, utility rooms and rental properties because they require very little maintenance. 

However, it is important not to confuse PVC roof windows with white polyurethane roof windows. They may look similar at first glance, but they are made differently. Learn more about upvc roof windows here.

Timber Roof Windows: White Painted vs Natural Pine 

When comparing timber vs uPVC roof windows, it helps to separate timber into two main categories: white-painted timber and natural pine. 

White-Painted Timber Roof Windows 

White-painted timber roof windows are now the go-to option for many modern homes. They have a timber frame with a factory-applied white painted finish, giving you the strength and quality of wood with a clean, contemporary appearance. 

Natural Pine Roof Windows 

Natural pine roof windows have a visible timber grain and a warmer, more traditional appearance. They are ideal if you want the roof window to stand out as a natural feature rather than blend into the ceiling. 

Brands such as RoofLITE+, FAKRO and Keylite still offer a strong selection of pine roof windows, making them a good choice for homeowners who prefer a more traditional finish. 

Like all timber products, pine may also require more care over time than PVC or polyurethane-coated windows. 

PVC Roof Windows: Practical, Durable and Low Maintenance 

PVC roof windows are designed for practicality. They are moisture resistant, easy to clean and ideal for areas where timber may need more maintenance. 

Unlike white-painted timber or pine roof windows, PVC roof windows do not have a visible timber frame. Many use multi-chamber PVC profiles and are designed to cope well with everyday condensation and humidity. 

PVC roof windows are a strong choice if you want a simple, reliable and low-maintenance option. They are particularly useful in rooms where steam and moisture are common. 

PVC roof windows are best for: 

• Bathrooms 

• Kitchens 

• Utility rooms 

• Laundry rooms 

• Rental properties 

• Homes where easy maintenance is a priority 

The smooth white finish is easy to wipe clean, which makes PVC a practical option for busy households. 

The main drawback of PVC is that it can feel less premium than timber or white polyurethane. While it is practical and cost-effective, it may not offer the same high-end finish as a timber-core polyurethane roof window. 

PVC may also be less suitable for traditional interiors where natural pine or painted timber would look more in keeping with the property. 

White Polyurethane Roof Windows: A Premium Moisture-Resistant Option 

White polyurethane roof windows are often grouped together with PVC roof windows, but they are not the same. 

A white polyurethane roof window usually has a timber core protected by a smooth, moulded polyurethane coating. This gives you the strength of a timber window with a durable, moisture-resistant surface. 

That makes white polyurethane one of the best choices for homeowners who want a more premium roof window for bathrooms, kitchens and en-suites. 

White polyurethane roof windows offer a high-quality finish with excellent moisture resistance. The smooth white surface is easy to clean and works well in modern interiors. 

Because the polyurethane coating protects the timber core, this finish is especially useful where moisture resistance is important but you still want a solid, premium-feeling product. 

PVC vs White Polyurethane Roof Windows: What Is the Difference? 

PVC and white polyurethane roof windows are both popular choices for bathrooms and kitchens, but they are made differently. 

The simplest way to understand the difference is this: 

• PVC roof windows are built from PVC profiles. 

• White polyurethane roof windows usually have a timber core with a protective polyurethane coating. 

That difference affects how the product feels, how it is positioned and how it is usually priced. 

PVC vs White Polyurethane Comparison Table 

Which Is Better: PVC or White Polyurethane? 

Both are good choices, but they suit different priorities. 

Choose PVC roof windows if you want a practical, cost-effective and low-maintenance option for a bathroom, kitchen, utility room or rental property. 

Choose white polyurethane roof windows if you want a more premium product with excellent moisture resistance and a smoother, more robust internal finish. 

For homeowners comparing quality, white polyurethane is usually seen as the higher-end option because it combines a protected timber core with a durable coated surface. 

Timber vs uPVC Roof Windows: Which Should You Choose? 

The best roof window finish depends on where the window is being installed and how the room is used. 

Best Roof Windows for Bedrooms 

For bedrooms, white-painted timber roof windows are usually the best all-round choice. They offer a bright, modern look while keeping the premium feel of timber. 

Natural pine can also work well in bedrooms if you want a warmer, more traditional appearance. 

Best Roof Windows for Loft Conversions 

For most loft conversions, white-painted timber roof windows are now the most popular option. They blend into the ceiling, help the room feel brighter and suit a wide range of interior styles. 

If the loft conversion includes an en-suite, consider white polyurethane or PVC for the bathroom area. 

Best for loft en-suites or Bathrooms  

For bathrooms, moisture resistance is the priority. That makes PVC and white polyurethane roof windows the best choices. 

PVC is a practical, cost-effective option. White polyurethane is the better choice if you want a more premium finish. 

Best Roof Windows for Kitchens 

Kitchens often produce steam, heat and condensation, so a low-maintenance finish is usually best. 

Choose PVC if practicality and value are most important. Choose white polyurethane if you want a more premium finish. 

Best Roof Windows for Period Homes 

For period homes, natural materials often work best. Natural pine roof windows are a good match for rustic or traditional interiors, while white-painted timber can suit period properties that have been modernised. 

Best Roof Windows for Rental Properties 

For rental properties, durability and low maintenance are key. PVC roof windows are often the most practical choice because they are easy to clean and well suited to regular use. 

In simple terms: 

Choose white-painted timber for modern style. 

Choose natural pine for traditional character.
