Sash window frame materials

Sash windows are known for their timeless elegance and classic design. They have been a prevalent choice for homeowners for centuries, and their popularity persists to grow. 

One of the key elements of sash windows is the frame material. 

This guide will look at the three most popular sash window frame materials: timber, uPVC, and aluminium. We’ll examine the benefits and drawbacks of each material and how they complement the design of sash windows.

Timber sash windows

Timber is the traditional and most popular choice of frame material. Wooden window frames are known for their natural beauty and warmth, which can enhance the aesthetic appeal of any home. Timber frames are also highly customisable, allowing homeowners to choose from various finishes, stains, and paint colours to match their home’s unique style.

Benefits:

• Natural beauty and warmth
• Highly customisable
• Durable and long-lasting
• Environmentally friendly

Drawbacks:

• Require semi-regular maintenance
• Can be susceptible to warping, rot, and insect damage if not properly maintained
• It can be more expensive than other frame materials

So, therefore, timber frames are an excellent choice for those looking for a traditional and elegant look. 

uPVC sash windows

uPVC window frames have gained popularity due to their low maintenance and durability. They are made from a type of plastic that is both lightweight and strong. uPVC frames are also energy-efficient, which can help to reduce heating bills.

Benefits:

• Low maintenance
• Durable and long-lasting
• Energy-efficient
• Affordable
• Offer extensive customization options, allowing for various finishes and colour choices, including wood grain options.

• Eco-conscious material due to its high recyclability, making it an environmentally friendly choice for window frames.

Drawbacks:

• Using cheaper or inferior-quality uPVC materials can result in poor-quality sash windows, which may not perform well regarding energy efficiency, noise reduction, or security.

• Can look out of place in traditional homes
• It can be more expensive than other materials, such as timber, which may be a better option for those on a tighter budget.

While uPVC frames may not have the same natural beauty as timber frames, they are perfect for those looking for a low-maintenance, energy-efficient option. They are the most affordable option for homes with a contemporary look, making them popular for homeowners on a budget.

Aluminium sash windows

Aluminium window frames are known for their strength, durability, and modern look. They are also highly customisable, with various colours and finishes available. Aluminium frames are also resistant to rust and corrosion, making them ideal for homes in coastal areas.

Benefits:

• Highly customisable
• Durable and long-lasting
• Resistant to rust and corrosion
• Modern look

Drawbacks:

• Less energy-efficient than uPVC frames
• It can be more expensive than other frame materials
• It may not complement the traditional look of sash windows

Aluminium frames are an excellent choice for those looking for a modern and customisable option. They are durable and resistant to rust and corrosion, making them ideal for homes in coastal areas. However, they may not complement the traditional look of sash windows.

Remember, the choice of sash window frame material is an important decision that should be based on your personal style, the sash window replacement cost, and maintenance preferences. Each material has its benefits and drawbacks, and choosing which one best suits your needs is up to you.

Double glazing or triple glazing? 

Double glazing or triple glazing, which one should you choose for your replacement sash windows? Let’s take a deeper look at the advantages and disadvantages of each option.

Double glazed sash windows

Double-glazed windows are made up of two glass panes separated by a layer of gas or air. They offer a range of benefits, including:

• Improved energy efficiency, as they provide better insulation and reduce heat loss
• Reduced noise pollution, making your home quieter and more peaceful
• Increased security, as they are harder to break than single glazed windows
• Reduced condensation, as the inner pane stays warmer, reducing moisture buildup.
• Double glazing is also eligible for window replacement grants, unlike other types of glazing.

However, there are some disadvantages to consider, such as:

• Cost: Compared to other double glazed window types, such as casement, tilt, and turn windows, Double-glazed sash windows are typically more expensive due to their complex design.
• Aesthetics: they can sometimes look thicker or less traditional than single glazed windows
• Planning permissions: Those living in heritage properties may not be allowed to replace their sash windows with double glazing.

Suppose you’re looking to replace your sash windows with double glazing. In that case, whether you want to replace the entire window or just the glazing panels is worth considering. Replacing the panels can be a more cost-effective option. It can also help you retain the traditional look of your sash windows.

Additionally, when replacing glazing panels with thicker double glazing, it’s important to consider the type of glazing bars that will work best for your replacement. Astragal bars offer a more traditional look, while Georgian bars offer a more modern style.

Triple glazed sash windows

On the other hand, triple glazed windows consist of three glass panes and two layers of gas or air. 

Some of the benefits of triple glazing include the following:

• Even greater energy efficiency, as they provide even better insulation than double glazing
• Reduced noise pollution, making your home even quieter than with double glazing
• Increased security, as they are even harder to break than double glazed windows

However, there are certain disadvantages to consider, such as:

• Higher cost: triple glazing can be significantly more expensive than double glazing
• Reduced light transmission: the extra layer of glass can reduce the amount of natural light that enters your home
• Aesthetics: they can look thicker and less traditional than both single and double glazed windows

Is triple glazing worth the extra investment, compared to double glazing?

There are many different types of double glazing and in case some improvement is needed, such as increased noise insulation, security, and reflection insulation, just choosing the right pane of the double glazing will do the trick. 

The biggest downside of triple glazing is its price and the fact that compared to double glazing it is around 30% more expensive.

So therefore, when considering replacing sash windows with double glazing or triple glazing, it’s also important to note that planning permissions may be required for glazing replacement in certain situations. 

For example, suppose your home is in a conservation area or listed building. In that case, you may need approval before making any changes to your sash windows. But if you need more ideas on how to go about it. Then, it will be most reasonable to consult with your local authority to determine whether this is necessary for your specific situation.

However, secondary glazing can be considered an alternative solution to avoid the regulatory process. This option can also provide benefits like improved energy efficiency, noise reduction, and enhanced security. 

In summary, deciding between double glazing and triple glazing ultimately depends on your individual needs and budget. However, both options offer a range of benefits for those looking to replace their sash windows with double glazing, if necessary.
