Timber

Recommended Timer Bifold
For the best balance of durability, stability and aesthetics, we recommend:

Accoya

Accoya is a high-performance modified timber that offers industry-leading stability and durability. It does not shrink or swell, ensuring windows and doors operate smoothly in every season. This stability prevents paint from cracking, meaning finishes last significantly longer. It is ideal for the British weather and is guaranteed against rot for 50 years.

Red Grandis

Red Grandis is a durable hardwood known for its consistent grain and uniform appearance. It provides an excellent, smooth surface for both paint and stains, making it a popular choice for premium joinery. Sourced from sustainable plantations, it offers a high-quality, stable, and ethically sound alternative to traditional hardwoods.

Tricoya

We often use Tricoya panels in our timber doors for their stability, weather resistance and longevity, particularly in exposed positions.

Finishes

Our finishes are done in house and we offer the following:

Opaque finishes

These coatings provide a flawless, uniform look in any shade. They offer maximum protection by blocking UV rays and sealing out moisture to prevent fading and timber movement.

Translucent finishes

Designed to showcase the wood’s natural grain and texture, these finishes provide a warm, organic aesthetic while maintaining a durable, weather-resistant shield.

RAL and custom colours

Choose from 147 standard colours or opt for our colour-matching service to RAL, British Standard, or NCS charts for a truly bespoke finish.

Factory finished

Every item is coated in a controlled factory environment before delivery. This ensures even coverage and superior adhesion for a professional, long-lasting result that on-site painting can’t match.

Glazing

We offer the following glazing options:

Standard double glazing

Unless a client requests an alternative specification, our joinery is typically supplied with 24 mm double-glazed units filled with Argon gas. In a unit of this thickness, alternative gases do not offer any meaningful improvement to thermal performance, so Argon represents the most effective and sensible choice in terms of insulation, reliability, and value.

Slim heritage units

For heritage properties or conservation areas with strict planning requirements, we offer slim double-glazed units. These are filled with Krypton gas, which performs more effectively than Argon in thinner cavities. This allows us to maintain slender, authentic profiles without sacrificing the thermal performance needed for a comfortable living environment.

Specialist and triple glazing

We offer a range of advanced glazing solutions for specific project needs. This includes triple glazing for superior acoustic and thermal insulation, as well as cutting-edge vacuum glazing. For those seeking an authentic period look, we can provide double-glazed units with drawn glass to recreate the subtle, classic distortions found in historic windows.
