The Brief
Project Overview
Karen Residence is a 59.4 m² home requiring a lightweight façade screen in dense urban conditions.
The timber system had to balance airflow, shade, and dimensional stability under humidity exposure.
Objective
The objective was to validate an Accoya Timberline screen system by delivering:
• Controlled ventilation and daylight diffusion
• Stable exterior performance under humidity
• Minimal maintenance lifecycle requirements
• Clean joinery alignment within compact urban constraints
This project reinforced façade performance as environmental engineering.
The Constraints
Urban Exposure Conditions
The facade faces heat, rain, and pollution. The material had to resist movement and surface degradation.
Airflow and Shade Calibration
Slat spacing required optimisation to balance ventilation with privacy and solar protection.
Low-Maintenance Requirement
The homeowner prioritised durability and reduced upkeep without compromising design quality.
Fine-Detail Expectations
Screen systems expose joints and edges. Any misalignment would disrupt visual rhythm.
The Engineering
Accoya Timberline System
Accoya was selected for its acetylated wood chemistry, which significantly reduces moisture absorption. Lower moisture uptake directly reduces swelling and shrinkage, protecting slat alignment under Jakarta’s humidity cycling.
Dimensional stability is the primary mechanism preserving facade straightness and consistent shadow lines over time.
Calibrated Slat Spacing Logic
Screen spacing was not aesthetic guesswork. Intervals were calculated to balance:
• Natural airflow
• Solar shading
• Visual privacy
• Structural stability
Spacing discipline ensures that ventilation does not compromise facade rhythm.
Ventilated Substructure Detailing
A ventilated cavity was integrated behind the slats to allow rear airflow and drying. This prevents moisture accumulation, reduces distortion risk, and extends service life.
Concealed mechanical fixing avoids surface stress concentration and protects visual clarity.
Precision Joinery and Alignment Control
Slats and frames were machined to controlled tolerances. Consistent spacing prevents cumulative deviation across long runs.
Alignment was treated as an engineered outcome, not a finishing correction.
The Products and Materials
The Results and Insights
Balanced Light and Privacy Achieved
The screen moderates daylight without over-darkening interiors.
Durability in Urban Climate Confirmed
Accoya’s stability reduces long-term warping and surface distortion.
Low-Maintenance Façade Delivered
The system supports long-term performance with minimal intervention.
Restraint as Architectural Strength
Karen Residence demonstrates that a disciplined timber screen can define identity without excess complexity.

Frequently Asked Questions
Got a question unanswered? Speak to our team.
Why use Accoya for façade screening?
Accoya undergoes acetylation, improving dimensional stability and resistance to moisture. This makes it suitable for humid urban climates with reduced maintenance demands.
How is airflow optimised in timber screens?
Through calibrated slat spacing, orientation, and ventilation detailing. Performance depends on precise alignment, not random placement.
Does a timber screen increase maintenance?
When engineered correctly with stable species and proper detailing, maintenance requirements remain manageable and predictable.
Why is this project strategically important for Woodlam?
Karen Residence reinforces Woodlam’s capability in engineered façade screening systems that balance environmental performance, durability, and restrained residential design.
