Types of Timber Windows
Timber windows come in a wide variety of opening types, performance abilities, maintenance requirements and lifespans. Here are three popular options:
Timber Casements
Timber casement windows are hinged at the side or along the top edge and open outwards. The frames and opening sashes can carry multiple lines of continuous compression seals which combined with single handle operated multi point locking can ensure Air Infiltration Resistance of the highest level. Due to Timber’s inherent strength opening sashes can be made significantly larger than PVCu sashes offering excellent ventilation and unobstructed views. They are perfect for homes that require a traditional look with modern performance.
Key Features:
- Superior weatherproofing
- High-security locking mechanisms
- Customisable styles and finishes

Through Window Advice Centre, you can get double glazed timber casements that not only look great but also perform exceptionally well in Scotland’s climate.
Timber Vertical Sliders
Timber vertically sliding windows (also known as off-set sash and case windows) are a quintessential feature of many traditional Scottish homes and are ideal for preserving the historical appearance and character of your property. Thermal performance and Air infiltration levels vary significantly depending upon the supplier and the requested performance specification. High performance thermally enhanced double glazed Sash and Case operate with multiple lines of brushpile draft strips embracing the edges of the sashes with compressions seals top and bottom can achieve high levels of resistance to Air Infiltration while still allowing the sashes to slide vertically with ease.

Timber Double Swings
Timber double swing windows are unique in their ability to present the appearance of off-set sash and case windows (when they are closed) while operating on compression seals with outward opening sashes that can fully rotate in the more expensive versions to allow cleaning of external glass surfaces from within. This versatility makes them a practical choice for many homeowners. Double swing windows above the ground floor with tall outward opening lower sashes may not comply with the safety requirements of the Building Regulations except where additional safety rails are fitted internally.
Key Features:
- Dual opening mechanisms for flexibility
- Enhanced air infiltration resistance
- Suitable for both traditional and contemporary settings

When Timber Window Replacements May Be Necessary
Recognising when to replace your windows is an important factor in maintaining the integrity and efficiency of your home. In Scotland, the decision to select Timber Windows is often influenced by planning restrictions, and conservation area requirements.
- Material Wear & Tear: Eventually timber windows will reach the point where the constant cost of maintaining the windows places them beyond economic repair. Many householders commit the majority of the cost of replacement to refurbish existing dilapidated timber windows only to find that their substantial outlay results in only marginal short lived improvement with drafts quickly recurring at near to previous levels, with minimal thermal improvement and re-painting becoming ever more frequent. Where slimline double glazed units are fitted into the old original sashes many householders experience operational difficulties due to the increase in the glass weight and recurring costs to replace failed sealed units due to the much reduced size and effectiveness of the units edge seals. Once original timber windows become dilapidated the most cost effective solution can often be replacement with a quality energy efficient long lasting timber replica when you factor in the additional energy savings these deliver combined with the reduction in ongoing maintenance and repair costs and the often substantial increase in property sales value compared to the sales value of the same property with patched up old inefficient single glazing.
Seeking expert advice from Window Advice Centre can help you navigate and financially optimise these issues while maintaining the historical character of your home and ensuring compliance with Scottish regulations.
