Timber Frame Insulation Enertherm ALU
Timber frame insulation fills or covers the spaces between structural timber studs to reduce heat loss, improve sound control, and ensure compliance with UK Building Regulations.
What is external timber frame insulation?
External wall insulation for timber-framed systems adds a protective thermal layer around the structure. It balances indoor temperatures for greater comfort and shields the frame from moisture.
Adding insulation to timber frames maintains a continuous thermal envelope that reduces cold bridging, keeping the building warmer for longer. Timber frame insulation options include rigid PIR boards, mineral wool slabs, and breathable external wall insulation systems.
What is timber frame insulation used for?
Effective insulation is essential for timber-framed builds, extensions, and renovations, focusing on sustainability and reduced energy use.
Timber frame insulation is installed to:
- Improve insulation levels and achieve target U-values in both external and internal walls.
- Reduce heat loss and lower energy bills.
- Minimise sound transfer between rooms or from outside.
- Guard against condensation and potential timber damage.
- Create a more comfortable and energy-efficient living space.
- Improve energy ratings for new constructions and retrofits.
Types of external wall insulation for timber frame
Builders choose insulation in timber-framed walls based on build type, performance target, and budget. Common options include:
PIR insulation boards
Premium-grade and lightweight, they have excellent thermal conductivity and are ideal for external wall insulation timber frame builds with limited space.
Mineral wool insulation
A natural, sustainable option that enhances breathability. Perfect for green or fire-resistant builds.
EPS insulation
Recognised for their exceptional stability and strength. An economical and quick-to-fit solution suitable for external wall render systems.
Insulated plasterboard
A two-in-one combination of plasterboard and rigid insulation. Provides a smooth, ready-to-finish internal wall lining.
Benefits of timber frame insulation
Fitting quality insulation into framed timber walls offers several long-term advantages:
- Better heat retention: Stable indoor temperatures year-round.
- Energy efficiency: Heating demand goes down.
- Moisture control: Protects the frame from damp and condensation.
- Acoustic comfort: Reduces noise transfer between floors, rooms, and external walls.
- Fire safety: Many insulating materials for timber-framed systems meet Class A2-s1, d0 or Class B-s1, d0 fire ratings, depending on material.
- Regulatory compliance: Supports compliance with Part L thermal efficiency and Part B fire safety requirements.
- Durability: Offers long-term, consistent thermal and acoustic performance.
- Sustainability: Supports low-carbon construction and long-term environmental performance.

FAQ
What is the best insulation for timber frame homes?
The proper insulation for a timber frame home varies with project goals and energy priorities. PIR boards offer high efficiency in compact spaces, whereas mineral wool ensures dependable fire safety and acoustic comfort. For eco-builds, wood fibre insulation delivers natural breathability and sustainability.
What insulation for timber frame extension?
Choose materials that match the main structure’s performance and durability. PIR and mineral wool boards typically meet these standards. These can be fixed within the wall studs or externally.
What is timber frame insulation?
This covers any insulation material that limits heat transfer and dampens sound within timber-framed walls. The insulation is fixed internally between studs, externally under cladding or render, or as part of a full wall system for energy-efficient construction.
