Why Pecasa Garden Rooms Built With SIP Panels Are a Superior Choice

When investing in a garden room, what you don’t see is just as important as what you do. Behind every beautifully finished Pecasa garden room is a carefully engineered structure designed for strength, insulation and long-term performance — and that’s where SIP panels make the difference.

What Are SIP Panels?

SIP panels (Structural Insulated Panels) are an advanced construction system made by bonding a high-performance insulating core between two structural boards. This creates a panel that is:

• Extremely strong
• Highly insulated
• Airtight and efficient

Pecasa uses SIP panels because they outperform traditional timber frame construction in almost every key area.

Superior Insulation & Year-Round Comfort

One of the biggest advantages of SIP panels is thermal performance. SIP construction drastically reduces heat loss, meaning your garden room stays warm in winter and cool in summer — without excessive heating or energy costs.

For customers who work from home or use their garden room daily, this makes a huge difference.

“The insulation is incredible. Even in cold weather, the room stays warm and comfortable all day.”

Stronger, More Solid Construction

Because SIP panels are structural, they create a rigid, solid building envelope. This means:

• Less movement over time
• Better durability
• A more “house-like” feel

Many customers comment that their Pecasa garden room feels like a permanent extension rather than a garden building.

“It feels incredibly solid — nothing like a typical garden room. You can really feel the quality.”

Airtight & Energy Efficient

SIP panels form a much tighter building envelope than traditional methods. Fewer gaps mean:

• Reduced drafts
• Improved energy efficiency
• More consistent internal temperatures

This airtightness not only improves comfort but also helps reduce long-term running costs.

Thicker Walls, Better Performance

Pecasa SIP panels are significantly thicker than standard garden room walls, allowing:

• Higher insulation values
• Better sound reduction
• More stable internal conditions

This is especially important for home offices, studios or therapy rooms where comfort and quiet matter.

“The sound insulation is excellent. It’s quiet, peaceful and perfect for working.”

Faster Build, Better Quality Control

SIP panels are precision-manufactured and prepared before installation. This allows Pecasa to:

• Maintain consistent quality
• Reduce on-site construction time
• Minimise disruption to your garden

Faster installation doesn’t mean cutting corners — it means better planning and better results.

Built to Last

A garden room should be a long-term investment. SIP panel construction offers:

• Long life expectancy
• Reduced risk of warping or thermal movement
• Strong structural integrity over time

Combined with premium external finishes and expert installation, Pecasa garden rooms are built to perform for decades.
