04Why Timber, Why Schnauber

What makes our timber windows special?

All timber is treated with waterproof sealants, LVL laminates and protective coatings in our workshop — then engineered with state-of-the-art German precision.

Tailor-Made Design

A wide range of designs, colours, finishes and glazing options — every window made to your exact specification.

Durability

Quality materials and modern manufacturing methods ensure every Schnauber window is guaranteed to last.

Virtually No Maintenance

Water-sealed finishes need attention only every 5–10 years — and alu-clad frames virtually none at all.

Safety & Security

Multi-point locking systems and precision-built frames as standard, for real peace of mind.

High Thermal Efficiency

Naturally resistant to heat loss — with double, triple, Slimlite or vacuum glazing to cut energy bills.

Eco-Friendly

Sustainably sourced timber from renewable forests, with responsible treatments and manufacturing.

Schnauber is FENSA registered — all installations comply with current building regulations and recognised industry standards, with certification provided for your peace of mind.

06Types of Timber Windows

Only hardwood or treated softwood — never compromise

Traditional untreated softwood frames often deteriorated in harsh weather. Some companies turned to plastic and metal — less sustainable, less environmentally friendly and rarely as beautiful as high-quality timber. Our extensive bespoke range includes:

Flush Casement WindowsStormproof Casement WindowsTilt & Turn WindowsTraditional Box Sash WindowsYorkshire-Style Sliding SashAlu-Clad Timber WindowsPassivhaus Certified WindowsHeritage Slimline WindowsVacuum Glazed Timber Windows

For heritage projects where original sightlines are essential, our ultra-slim vacuum glazing delivers outstanding thermal efficiency while preserving the delicate appearance required for listed and period properties.
