Which insulation board should you choose for an external wall insulation system?

Three types of insulation, three ways to insulate effectively

The choice of an insulating panel for an external thermal insulation system (ETIS) is based on four criteria:

  • its thermal conductivity (λ), which determines the required thickness;
  • its fire performance;
  • its vapour permeability, i.e. its ability to allow the wall to ‘breathe’;
  • its price.
Centrale ITE offers three product ranges: White EPS Graphite-reinforced EPS Rock wool Wood fibre λD (W/m·K) 0.038 0.031 to 0.032 0.035 to 0.036 0.037 to 0.038 Fire Euroclass E Euroclass E Euroclass A1 Euroclass E Key features Lightweight, economical Better performance for the same thickness Non-combustible, vapour-permeable, good sound insulation Summer comfort, vapour-permeable (µ 3) References Isol France TH38 TH31 and TH32 Re Coat+, Isofacade 35R Gutex Thermowall-L EPS is the most cost-effective and easiest-to-install solution. Graphite-reinforced, grey EPS achieves the same performance with a thinner layer. Rock wool is essential where required by fire safety regulations, and is recommended for older buildings. Gutex Thermowall-Lwood fibre is dense (approximately 110 kg/m³) and has a high thermal capacity (2,100 J/kg·K). It delays heat gain in summer, making it the ideal insulation for summer comfort.

Thickness of external wall insulation and thermal resistance R

The right thickness for the right performance

The thickness of insulation depends on the target thermal resistance (R) and the thermal conductivity (λ) of the material, according to the formula R = thickness / λ. In France, R 3.7 m².K/W is the benchmark for high-performance external wall insulation that is eligible for renovation grants. To achieve this, you need to: Insulation Thickness for R ≈ 3.7 Graphite-modified expanded polystyrene (EPS) λ 0.031 115 mm Rock wool, λ 0.035 130 mm White expanded polystyrene (EPS) λ 0.038 140 mm Wood fibre λ 0.037 140 mm (R 3.75) ACERMI-certified thermal resistance values for white EPS TH38 in 1200 × 600 mm: Thickness Certified R-value 100 mm 2.60 120 mm 3.15 140 mm 3.70 160 mm 4.20 180 mm 4.75 Installation. The panels are laid with staggered joints, bonded using dots and beads of adhesive (approximately 4 kg/m² of A 96 adhesive), then fixed with approximately 7 fixings per m². Storage. Store the panels away from the rain, in their original packaging. A panel that is damp, warped or damaged must never be installed.

لا توجد أي مادة قادرة على تحمل جميع أشكال الضغط؛ ويُعد البوليسترين الموسع المقوى بالجرافيت (EPS) هو الأكثر مقاومة للتشوه. يضمن الكرتون القوي، ذو السماكة (A1)، والتركيب على الحائط «تركيبًا مثاليًا». تخلق الزوايا الأربع، في حد ذاتها، إحساسًا بالهدوء، مما يسمح للضوء الطبيعي بتدفق الضوء عبر المساحة. يتم تثبيت الهيكل في الجزء الخلفي من السقف باستخدام قاعدة خشبية، مما يضمن استقرار العوارض وكذلك السلامة الهيكلية.
أنبوب من البوليستيرين بقطر 115 مم، مغطى بطبقة من الجرافيت-البوليستيرين (EPS) (λ 0.031)، مع فراغ يبلغ 130 مم (λ 0.035) و140 مم من البوليستيرين الموسع (EPS) (λ 0.038) أو مادة عازلة من الجيلتي (λ 0.037). كما تجدر الإشارة إلى أن الألواح تتوافق مع مواصفات ACERMI الخاصة بالتدفئة.
EPS يُصنع باستخدام الجرافيت — وفي نفس العملية، يمكن ملاحظة أن درجة حرارة الكتابة أعلى بحوالي 20 درجة من درجة حرارة الجرافيت (λ 0.038 مقارنة بـ 0.031): وهو ما، في هذا السياق، يساهم في دقة القياسات، مما يوفر حماية أكبر ضد أشعة الشمس على النوافذ والأبواب، وكذلك على حواف عتبات النوافذ. وهذه سمة تاريخية مهمة: يُظهر EPS مقاومة ميكانيكية فائقة.
